# Installing the Trivy-Operator through GitOps
|
|
|
|
This tutorial shows you how to install the Trivy Operator through GitOps platforms, namely ArgoCD and FluxCD.
|
|
|
|
## ArgoCD
|
|
|
|
Make sure to have [ArgoCD installed](https://argo-cd.readthedocs.io/en/stable/getting_started/) and running in your Kubernetes cluster.
|
|
|
|
You can either deploy the Trivy Operator through the argocd CLI or by applying a Kubernetes manifest.
|
|
|
|
ArgoCD command:
|
|
```
|
|
> kubectl create ns trivy-system
|
|
> argocd app create trivy-operator --repo https://github.com/aquasecurity/trivy-operator --path deploy/helm --dest-server https://kubernetes.default.svc --dest-namespace trivy-system
|
|
```
|
|
Note that this installation is directly related to our official Helm Chart. If you want to change any of the value, we'd suggest you to create a separate values.yaml file.
|
|
|
|
Kubernetes manifest `trivy-operator.yaml`:
|
|
```
|
|
apiVersion: argoproj.io/v1alpha1
|
|
kind: Application
|
|
metadata:
|
|
name: trivy-operator
|
|
namespace: argocd
|
|
spec:
|
|
project: default
|
|
source:
|
|
chart: trivy-operator
|
|
repoURL: https://aquasecurity.github.io/helm-charts/
|
|
targetRevision: 0.0.3
|
|
helm:
|
|
values: |
|
|
trivy:
|
|
ignoreUnfixed: true
|
|
destination:
|
|
server: https://kubernetes.default.svc
|
|
namespace: trivy-system
|
|
syncPolicy:
|
|
automated:
|
|
prune: true
|
|
selfHeal: true
|
|
```
|
|
|
|
The apply the Kubernetes manifest. If you have the manifest locally, you can use the following command through kubectl:
|
|
```
|
|
> kubectl apply -f trivy-operator.yaml
|
|
|
|
application.argoproj.io/trivy-operator created
|
|
```
|
|
|
|
If you have the manifest in a Git repository, you can apply it to your cluster through the following command:
|
|
```
|
|
> kubectl apply -n argocd -f https://raw.githubusercontent.com/AnaisUrlichs/argocd-starboard/main/starboard/argocd-starboard.yaml
|
|
```
|
|
The latter command would allow you to make changes to the YAML manifest that ArgoCD would register automatically.
|
|
|
|
Once deployed, you want to tell ArgoCD to sync the application from the actual state to the desired state:
|
|
```
|
|
argocd app sync trivy-operator
|
|
```
|
|
|
|
Now you can see the deployment in the ArgoCD UI. Have a look at the ArgoCD documentation to know how to access the UI.
|
|
|
|
|
|
|
|
Note that ArgoCD is unable to show the Trivy CRDs as synced.
|
|
|
|
|
|
## FluxCD
|
|
|
|
Make sure to have [FluxCD installed](https://fluxcd.io/docs/installation/#install-the-flux-cli) and running in your Kubernetes cluster.
|
|
|
|
You can either deploy the Trivy Operator through the Flux CLI or by applying a Kubernetes manifest.
|
|
|
|
Flux command:
|
|
```
|
|
> kubectl create ns trivy-system
|
|
> flux create source helm trivy-operator --url https://aquasecurity.github.io/helm-charts --namespace trivy-system
|
|
> flux create helmrelease trivy-operator --chart trivy-operator
|
|
--source HelmRepository/trivy-operator
|
|
--chart-version 0.0.3
|
|
--namespace trivy-system
|
|
```
|
|
|
|
Kubernetes manifest `trivy-operator.yaml`:
|
|
```
|
|
apiVersion: source.toolkit.fluxcd.io/v1beta2
|
|
kind: HelmRepository
|
|
metadata:
|
|
name: trivy-operator
|
|
namespace: flux-system
|
|
spec:
|
|
interval: 60m
|
|
url: https://aquasecurity.github.io/helm-charts/
|
|
|
|
---
|
|
apiVersion: helm.toolkit.fluxcd.io/v2beta1
|
|
kind: HelmRelease
|
|
metadata:
|
|
name: trivy-operator
|
|
namespace: trivy-system
|
|
spec:
|
|
chart:
|
|
spec:
|
|
chart: trivy-operator
|
|
sourceRef:
|
|
kind: HelmRepository
|
|
name: trivy-operator
|
|
namespace: flux-system
|
|
version: 0.0.5
|
|
interval: 60m
|
|
```
|
|
|
|
You can then apply the file to your Kubernetes cluster:
|
|
```
|
|
kubectl apply -f trivy-operator.yaml
|
|
```
|
|
|
|
## After the installation
|
|
|
|
After the install, you want to check that the Trivy operator is running in the trivy-system namespace:
|
|
```
|
|
kubectl get deployment -n trivy-system
|
|
```
|
|
