Thank you for taking interest in contributing to Trivy !
## Issues
- Feel free to open issues for any reason. When you open a new issue, you'll have to select an issue kind: bug/feature/support and fill the required information based on the selected template.
- Please spend a small amount of time giving due diligence to the issue tracker. Your issue might be a duplicate. If it is, please add your comment to the existing issue.
- Remember users might be searching for your issue in the future, so please give it a meaningful title to help others.
- The issue should clearly explain the reason for opening, the proposal if you have any, and any relevant technical information.
## Pull Requests
1. Every Pull Request should have an associated bug or feature issue unless you are fixing a trivial documentation issue.
1. Your PR is more likely to be accepted if it focuses on just one change.
1. Describe what the PR does. There's no convention enforced, but please try to be concise and descriptive. Treat the PR description as a commit message. Titles that starts with "fix"/"add"/"improve"/"remove" are good examples.
1. Please add the associated Issue in the PR description.
1. There's no need to add or tag reviewers.
1. If a reviewer commented on your code or asked for changes, please remember to mark the discussion as resolved after you address it. PRs with unresolved issues should not be merged (even if the comment is unclear or requires no action from your side).
1. Please include a comment with the results before and after your change.
1. Your PR is more likely to be accepted if it includes tests (We have not historically been very strict about tests, but we would like to improve this!).
1. If your PR affects the user experience in some way, please update the Readme and the CLI help accordingly.
## Understand where your pull request belongs
Trivy is composed of several different repositories that work together:
- [Trivy](https://github.com/aquasecurity/trivy) is the client-side, user-facing, command line tool.
- [vuln-list](https://github.com/aquasecurity/vuln-list) is a vulnerabilities database, aggregated from different sources, and normalized for easy consumption. This of this as the "server" side of the trivy command line tool. **There should be no pull requests to this repo**
- [vuln-list-update](https://github.com/aquasecurity/vuln-list-update) is the code that maintains the vuln-list database.
- [fanal](https://github.com/aquasecurity/fanal) is a library for extracting system information containers. It is being used by Trivy to find testable subjects in the container image.

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the

work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.

and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only

# Abstract
`Trivy` (`tri` pronounced like **tri**gger, `vy` pronounced like en**vy**) is a simple and comprehensive scanner for vulnerabilities in container images, file systems, and Git repositories, as well as for configuration issues.
`Trivy` detects vulnerabilities of OS packages (Alpine, RHEL, CentOS, etc.) and language-specific packages (Bundler, Composer, npm, yarn, etc.).
In addition, `Trivy` scans Infrastructure as Code (IaC) files such as Terraform, Dockerfile and Kubernetes, to detect potential configuration issues that expose your deployments to the risk of attack.
`Trivy` is easy to use. Just install the binary and you're ready to scan.

# Quick Start
## Scan Image for Vulnerabilities
Simply specify an image name (and a tag).
```
$ trivy image [YOUR_IMAGE_NAME]
```
For example:
```
$ trivy image python:3.4-alpine
```

# Air-Gapped Environment
Trivy can be used in air-gapped environments.
## Download the vulnerability database
At first, you need to download the vulnerability database for use in air-gapped environments.
Go to [trivy-db][trivy-db] and download `trivy-offline.db.tgz` in the latest release.
If you download `trivy-light-offline.db.tgz`, you have to run Trivy with `--light` option.
```
$ wget https://github.com/aquasecurity/trivy-db/releases/latest/download/trivy-offline.db.tgz
```
## Transfer the DB file into the air-gapped environment
The way of transfer depends on the environment.
```
$ rsync -av -e ssh /path/to/trivy-offline.db.tgz [user]@[host]:dst
```
## Put the DB file in Trivy's cache directory
You have to know where to put the DB file. The following command shows the default cache directory.
```
$ ssh user@host
$ trivy -h | grep cache
--cache-dir value cache directory (default: "/home/myuser/.cache/trivy") [$TRIVY_CACHE_DIR]
```
Put the DB file in the cache directory + `/db`.
```
$ mkdir -p /home/myuser/.cache/trivy/db
$ cd /home/myuser/.cache/trivy/db
$ mv /path/to/trivy-offline.db.tgz .
```
Then, decompress it.
`trivy-offline.db.tgz` file includes two files, `trivy.db` and `metadata.json`.
```
$ tar xvf trivy-offline.db.tgz
x trivy.db
x metadata.json
$ rm trivy-offline.db.tgz
```
In an air-gapped environment it is your responsibility to update the Trivy database on a regular basis, so that the scanner can detect recently-identified vulnerabilities.
## Run Trivy with --skip-update option
In an air-gapped environment, specify `--skip-update` so that Trivy doesn't attempt to download the latest database file.
```
$ trivy image --skip-update alpine:3.12
```

# Embed in Dockerfile
Scan your image as part of the build process by embedding Trivy in the
Dockerfile. This approach can be used to update Dockerfiles currently using
Aquas [Microscanner][microscanner].
```bash
$ cat Dockerfile
FROM alpine:3.7
RUN apk add curl \
&& curl -sfL https://raw.githubusercontent.com/aquasecurity/trivy/main/contrib/install.sh | sh -s -- -b /usr/local/bin \
&& trivy filesystem --exit-code 1 --no-progress /
$ docker build -t vulnerable-image .
```
Alternatively you can use Trivy in a multistage build. Thus avoiding the
insecure `curl | sh`. Also the image is not changed.
```bash
[...]
# Run vulnerability scan on build image
FROM build AS vulnscan
COPY --from=aquasec/trivy:latest /usr/local/bin/trivy /usr/local/bin/trivy
RUN trivy filesystem --exit-code 1 --no-progress /

# Podman
!!! warning "EXPERIMENTAL"
This feature might change without preserving backwards compatibility.
Scan your image in Podman (>=2.0) running locally. The remote Podman is not supported.
Before performing Trivy commands, you must enable the podman.sock systemd service on your machine.
For more details, see [here][sock].
```bash
$ systemctl --user enable --now podman.socket
```
Then, you can scan your image in Podman.

# Overview
We use two labels [help wanted](#help-wanted) and [good first
issue](#good-first-issue) to identify issues that have been specially groomed
for new contributors. The `good first issue` label is a subset of `help wanted`
label, indicating that members have committed to providing extra assistance for
new contributors. All `good first issue` items also have the `help wanted`
label.
## Help Wanted
Items marked with the `help wanted` label need to ensure that they are:
- **Low Barrier to Entry**
It should be tractable for new contributors. Documentation on how that type of
change should be made should already exist.
- **Clear Task**
The task is agreed upon and does not require further discussions in the
community. Call out if that area of code is untested and requires new
fixtures.
API / CLI behavior is decided and included in the OP issue, for example: "The
new command syntax is `trivy --format yaml IMAGE_NAME`"_ with
expected validations called out.
- **Goldilocks priority**
Not too high that a core contributor should do it, but not too low that it
isn't useful enough for a core contributor to spend time to review it, answer
questions, help get it into a release, etc.
- **Up-To-Date**
Often these issues become obsolete and have already been done, are no longer
desired, no longer make sense, have changed priority or difficulty , etc.
## Good First Issue
Items marked with the `good first issue` label are intended for _first-time
contributors_. It indicates that members will keep an eye out for these pull
requests and shepherd it through our processes.
These items need to ensure that they follow the guidelines for `help wanted`
labels (above) in addition to meeting the following criteria:
- **No Barrier to Entry**
The task is something that a new contributor can tackle without advanced
setup, or domain knowledge.
- **Solution Explained**
The recommended solution is clearly described in the issue.
- **Provides Context**
If background knowledge is required, this should be explicitly mentioned and a
list of suggested readings included.
- **Gives Examples**
Link to examples of similar implementations so new contributors have a
reference guide for their changes.
- **Identifies Relevant Code**
The relevant code and tests to be changed should be linked in the issue.
- **Ready to Test**
There should be existing tests that can be modified, or existing test cases
fit to be copied. If the area of code doesn't have tests, before labeling the
issue, add a test fixture. This prep often makes a great `help wanted` task!

Triage is an important part of maintaining the health of the trivy repo.
A well organized repo allows maintainers to prioritize feature requests, fix bugs, and respond to users facing difficulty with the tool as quickly as possible.
Triage includes:
- Labeling issues
- Responding to issues
- Closing issues
# Daily Triage
Daily triage has two goals:
1. Responsiveness for new issues
1. Responsiveness when explicitly requested information was provided
It covers:
1. Issues without a `kind/` or `triage/` label
1. Issues without a `priority/` label
1. `triage/needs-information` issues which the user has followed up on, and now require a response.
## Categorization
The most important level of categorizing the issue is defining what type it is.
We typically want at least one of the following labels on every issue, and some issues may fall into multiple categories:
- `triage/support` - The default for most incoming issues
- `kind/bug` - When its a bug or we arent delivering the best user experience
Other possibilities:
- `kind/feature`- Identify new feature requests
- `kind/testing` - Update or fix unit/integration tests
- `kind/cleanup` - Cleaning up/refactoring the codebase
- `kind/documentation` - Updates or additions to trivy documentation
If the issue is specific to a driver for OS packages or libraries:
**co/[driver for OS packages]**
- `co/alpine`
- `co/amazon`
- `co/debian`
- `co/oracle`
- `co/photon`
- `co/redhat`
- `co/suse`
- `co/ubuntu`
**co/[driver for libraries of programming languages]**
- `co/bundler`
- `co/cargo`
- `co/composer`
- `co/npm`
- `co/yarn`
- `co/pipenv`
- `co/poetry`
**Help wanted?**
`Good First Issue` - bug has a proposed solution, can be implemented w/o further discussion.
`Help wanted` - if the bug could use help from a contributor
## Prioritization
If the issue is not `triage/support`, it needs a priority label.
`priority/critical-urgent` - someones top priority ASAP, such as security issue, user-visible bug, or build breakage. Rarely used.
`priority/important-soon`: in time for the next two releases. It should be attached to a milestone.
`priority/important-longterm`: 2-4 releases from now
`priority/backlog`: agreed that this would be good to have, but no one is available at the moment. Consider tagging as `help wanted`
`priority/awaiting-more-evidence`: may be useful, but there is not yet enough support.
# Weekly Triage
Weekly triage has three goals:
1. Catching up on unresponded issues
1. Reviewing and closing PRs
1. Closing stale issues
## Post-Release Triage
Post-release triage occurs after a major release (around every 4-6 weeks).
It focuses on:
1. Closing bugs that have been resolved by the release
1. Reprioritizing bugs that have not been resolved by the release
1. Letting users know if we believe that there is still an issue
This includes reviewing:
1. Every issue that hasnt been touched in the last 2 days
1. Re-evaluation of long-term issues
1. Re-evaluation of short-term issues
## Responding to Issues
### Needs More Information
A sample response to ask for more info:
> I dont yet have a clear way to replicate this issue. Do you mind adding some additional details. Here is additional information that would be helpful:
>
> \* The exact `trivy` command line used
>
> \* The exact image you want to scan
>
> \* The full output of the `trivy` command, preferably with `--debug` for extra logging.
>
>
> Thank you for sharing your experience!
Then: Label with `triage/needs-information`.
### Issue might be resolved
If you think a release may have resolved an issue, ask the author to see if their issue has been resolved:
> Could you please check to see if trivy <x> addresses this issue? We've made some changes with how this is handled, and improved the trivy logs output to help us debug tricky cases like this.
Then: Label with `triage/needs-information`.
## Closing with Care
Issues typically need to be closed for the following reasons:
- The issue has been addressed
- The issue is a duplicate of an existing issue
- There has been a lack of information over a long period of time
In any of these situations, we aim to be kind when closing the issue, and offer the author action items should they need to reopen their issue or still require a solution.
Samples responses for these situations include:
### Issue has been addressed
>@author: I believe this issue is now addressed by trivy v1.0.0, as it <reason>. If you still see this issue with trivy v1.0 or higher, please reopen this issue.
>
>Thank you for reporting this issue!
Then: Close the issue
### Duplicate Issue
>This issue appears to be a duplicate of #X, do you mind if we move the conversation there?
>
>This way we can centralize the content relating to the issue. If you feel that this issue is not in fact a duplicate, please re-open it. If you have additional information to share, please add it to the new issue.
>
>Thank you for reporting this!
Then: Label with `triage/duplicate` and close the issue.
### Lack of Information
If an issue hasn't been active for more than four weeks, and the author has been pinged at least once, then the issue can be closed.
>Hey @author -- hopefully it's OK if I close this - there wasn't enough information to make it actionable, and some time has already passed. If you are able to provide additional details, you may reopen it at any point.
>
>Here is additional information that may be helpful to us:
>
>\* Whether the issue occurs with the latest trivy release
>
>\* The exact `trivy` command line used
>
>\* The exact image you want to scan
>
>\* The full output of the `trivy` command, preferably with `--debug` for extra logging.
>
>
>Thank you for sharing your experience!
Then: Close the issue.
## Help Wanted issues
We use two labels [help wanted](https://github.com/aquasecurity/trivy/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22)
and [good first issue](https://github.com/aquasecurity/trivy/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22)
to identify issues that have been specially groomed for new contributors.
We have specific [guidelines](/docs/advanced/contribd/contrib/help-wanted.md)
for how to use these labels. If you see an issue that satisfies these
guidelines, you can add the `help wanted` label and the `good first issue` label.
Please note that adding the `good first issue` label must also
add the `help wanted` label.
If an issue has these labels but does not satisfy the guidelines, please
ask for more details to be added to the issue or remove the labels.

### GitLab CI using Trivy container
To scan a previously built image that has already been pushed into the
GitLab container registry the following CI job manifest can be used.
Note that `entrypoint` needs to be unset for the `script` section to work.
In case of a non-public GitLab project Trivy additionally needs to
authenticate to the registry to be able to pull your application image.
Finally, it is not necessary to clone the project repo as we only work
with the container image.
```yaml
container_scanning:
image:
name: docker.io/aquasec/trivy:latest
entrypoint: [""]
variables:
# No need to clone the repo, we exclusively work on artifacts. See
# https://docs.gitlab.com/ee/ci/runners/README.html#git-strategy
GIT_STRATEGY: none
TRIVY_USERNAME: "$CI_REGISTRY_USER"
TRIVY_PASSWORD: "$CI_REGISTRY_PASSWORD"
TRIVY_AUTH_URL: "$CI_REGISTRY"
FULL_IMAGE_NAME: $CI_REGISTRY_IMAGE:$CI_COMMIT_REF_SLUG
script:
- trivy --version
# cache cleanup is needed when scanning images with the same tags, it does not remove the database
- time trivy image --clear-cache
# update vulnerabilities db
- time trivy --download-db-only --no-progress --cache-dir .trivycache/
# Builds report and puts it in the default workdir $CI_PROJECT_DIR, so `artifacts:` can take it from there
- time trivy --exit-code 0 --cache-dir .trivycache/ --no-progress --format template --template "@/contrib/gitlab.tpl"

### Gitlab CI alternative template
Depending on the edition of gitlab you have or your desired workflow, the
container scanning template may not meet your needs. As an addition to the
above container scanning template, a template for
[code climate](https://docs.gitlab.com/ee/user/project/merge_requests/code_quality.html)
has been included. The key things to update from the above examples are
the `template` and `report` type. An updated example is below.
```yaml
stages:
- test
trivy:
stage: test
image: docker:stable
services:
- name: docker:dind

- wget --no-verbose https://github.com/aquasecurity/trivy/releases/download/v${TRIVY_VERSION}/trivy_${TRIVY_VERSION}_Linux-64bit.tar.gz -O - | tar -zxvf -

cache:
paths:
- .trivycache/
# Enables https://docs.gitlab.com/ee/user/application_security/container_scanning/ (Container Scanning report is available on GitLab EE Ultimate or GitLab.com Gold)
artifacts:
paths:
gl-codeclimate.json
reports:
codequality: gl-codeclimate.json
```
Currently gitlab only supports a single code quality report. There is an
open [feature request](https://gitlab.com/gitlab-org/gitlab/-/issues/9014)
to support multiple reports. Until this has been implemented, if you
already have a code quality report in your pipeline, you can use
`jq` to combine reports. Depending on how you name your artifacts, it may
be necessary to rename the artifact if you want to reuse the name. To then
combine the previous artifact with the output of trivy, the following `jq`
command can be used, `jq -s 'add' prev-codeclimate.json trivy-codeclimate.json > gl-codeclimate.json`.

# Integrations
Scan your image automatically as part of your CI workflow, failing the workflow if a vulnerability is found. When you don't want to fail the test, specify `--exit-code 0`.
Since in automated scenarios such as CI/CD you are only interested in the end result, and not the full report, use the `--light` flag to optimize for this scenario and get fast results.

# Client/Server
Trivy has client/server mode. Trivy server has vulnerability database and Trivy client doesn't have to download vulnerability database. It is useful if you want to scan images at multiple locations and do not want to download the database at every location.
## Server
At first, you need to launch Trivy server. It downloads vulnerability database automatically and continue to fetch the latest DB in the background.
```
$ trivy server --listen localhost:8080
2019-12-12T15:17:06.551+0200 INFO Need to update DB

2019-12-12T15:17:56.707+0200 INFO Listening localhost:8080...
```
If you want to accept a connection from outside, you have to specify `0.0.0.0` or your ip address, not `localhost`.
```
$ trivy server --listen 0.0.0.0:8080
```
## Client
Then, specify the remote address.
```
$ trivy client --remote http://localhost:8080 alpine:3.10
```
<details>
<summary>Result</summary>

# Plugins
Trivy provides a plugin feature to allow others to extend the Trivy CLI without the need to change the Trivycode base.
This plugin system was inspired by the plugin system used in [kubectl][kubectl], [Helm][helm], and [Conftest][conftest].
## Overview
Trivy plugins are add-on tools that integrate seamlessly with Trivy.
They provide a way to extend the core feature set of Trivy, but without requiring every new feature to be written in Go and added to the core tool.
- They can be added and removed from a Trivy installation without impacting the core Trivy tool.
- They can be written in any programming language.
- They integrate with Trivy, and will show up in Trivy help and subcommands.
!!! warning
Trivy plugins available in public are not audited for security.
You should install and run third-party plugins at your own risk, since they are arbitrary programs running on your machine.
## Installing a Plugin
A plugin can be installed using the `trivy plugin install` command.
This command takes a url and will download the plugin and install it in the plugin cache.
Trivy adheres to the XDG specification, so the location depends on whether XDG_DATA_HOME is set.
Trivy will now search XDG_DATA_HOME for the location of the Trivy plugins cache.
The preference order is as follows:
- XDG_DATA_HOME if set and .trivy/plugins exists within the XDG_DATA_HOME dir
- ~/.trivy/plugins
Under the hood Trivy leverages [go-getter][go-getter] to download plugins.
This means the following protocols are supported for downloading plugins:
- OCI Registries
- Local Files
- Git
- HTTP/HTTPS
- Mercurial
- Amazon S3
- Google Cloud Storage
For example, to download the Kubernetes Trivy plugin you can execute the following command:
```bash
$ trivy plugin install github.com/aquasecurity/trivy-plugin-kubectl
```
## Using Plugins
Once the plugin is installed, Trivy will load all available plugins in the cache on the start of the next Trivy execution.
A plugin will be made in the Trivy CLI based on the plugin name.
To display all plugins, you can list them by `trivy --help`
```bash
$ trivy --help
NAME:
trivy - A simple and comprehensive vulnerability scanner for containers
USAGE:
trivy [global options] command [command options] target
VERSION:
dev
COMMANDS:
image, i scan an image
filesystem, fs scan local filesystem
repository, repo scan remote repository
client, c client mode
server, s server mode
plugin, p manage plugins
kubectl scan kubectl resources
help, h Shows a list of commands or help for one command
```
As shown above, `kubectl` subcommand exists in the `COMMANDS` section.
To call the kubectl plugin and scan existing Kubernetes deployments, you can execute the following command:
```
$ trivy kubectl deployment <deployment-id> -- --ignore-unfixed --severity CRITICAL
```
Internally the kubectl plugin calls the kubectl binary to fetch information about that deployment and passes the using images to Trivy.
You can see the detail [here][trivy-plugin-kubectl].
If you want to omit even the subcommand, you can use `TRIVY_RUN_AS_PLUGIN` environment variable.
```bash
$ TRIVY_RUN_AS_PLUGIN=kubectl trivy job your-job -- --format json
```
## Installing and Running Plugins on the fly
`trivy plugin run` installs a plugin and runs it on the fly.
If the plugin is already present in the cache, the installation is skipped.
```bash
trivy plugin run github.com/aquasecurity/trivy-plugin-kubectl pod your-pod -- --exit-code 1
```
## Uninstalling Plugins
Specify a plugin name with `trivy plugin uninstall` command.
```bash
$ trivy plugin uninstall kubectl
```
## Building Plugins
Each plugin has a top-level directory, and then a plugin.yaml file.
```bash
your-plugin/
|
|- plugin.yaml
|- your-plugin.sh
```
In the example above, the plugin is contained inside of a directory named `your-plugin`.
It has two files: plugin.yaml (required) and an executable script, your-plugin.sh (optional).
The core of a plugin is a simple YAML file named plugin.yaml.
Here is an example YAML of trivy-plugin-kubectl plugin that adds support for Kubernetes scanning.
```yaml
name: "kubectl"
repository: github.com/aquasecurity/trivy-plugin-kubectl
version: "0.1.0"
usage: scan kubectl resources
description: |-
A Trivy plugin that scans the images of a kubernetes resource.
Usage: trivy kubectl TYPE[.VERSION][.GROUP] NAME
platforms:
- selector: # optional
os: darwin
arch: amd64
uri: ./trivy-kubectl # where the execution file is (local file, http, git, etc.)
bin: ./trivy-kubectl # path to the execution file
- selector: # optional
os: linux
arch: amd64
uri: https://github.com/aquasecurity/trivy-plugin-kubectl/releases/download/v0.1.0/trivy-kubectl.tar.gz
bin: ./trivy-kubectl
```
The `plugin.yaml` field should contain the following information:
- name: The name of the plugin. This also determines how the plugin will be made available in the Trivy CLI. For example, if the plugin is named kubectl, you can call the plugin with `trivy kubectl`. (required)
- version: The version of the plugin. (required)
- usage: A short usage description. (required)
- description: A long description of the plugin. This is where you could provide a helpful documentation of your plugin. (required)
- platforms: (required)
- selector: The OS/Architecture specific variations of a execution file. (optional)
- os: OS information based on GOOS (linux, darwin, etc.) (optional)
- arch: The architecture information based on GOARCH (amd64, arm64, etc.) (optional)
- uri: Where the executable file is. Relative path from the root directory of the plugin or remote URL such as HTTP and S3. (required)
- bin: Which file to call when the plugin is executed. Relative path from the root directory of the plugin. (required)
The following rules will apply in deciding which platform to select:
- If both `os` and `arch` under `selector` match the current platform, search will stop and the platform will be used.
- If `selector` is not present, the platform will be used.
- If `os` matches and there is no more specific `arch` match, the platform will be used.
- If no `platform` match is found, Trivy will exit with an error.
After determining platform, Trivy will download the execution file from `uri` and store it in the plugin cache.
When the plugin is called via Trivy CLI, `bin` command will be executed.
The plugin is responsible for handling flags and arguments. Any arguments are passed to the plugin from the `trivy` command.

# Overview
Trivy detects two types of security issues:
- [Vulnerabilities][vuln]
- [Misconfigurations][misconf]
Trivy can scan three different artifacts:
- [Container Images][container]
- [Filesystem][filesystem]
- [Git Repositories][repo]
Trivy can be run in two different modes:
- [Standalone][standalone]
- [Client/Server][client-server]
It is designed to be used in CI. Before pushing to a container registry or deploying your application, you can scan your local container image and other artifacts easily.
See [Integrations][integrations] for details.
## Features
- Comprehensive vulnerability detection
- [OS packages][os] (Alpine, Red Hat Universal Base Image, Red Hat Enterprise Linux, CentOS, Oracle Linux, Debian, Ubuntu, Amazon Linux, openSUSE Leap, SUSE Enterprise Linux, Photon OS and Distroless)
- [**Language-specific packages**][lang] (Bundler, Composer, Pipenv, Poetry, npm, yarn, Cargo, NuGet, Maven, and Go)
- Detect IaC misconfigurations
- A wide variety of [built-in policies][builtin] are provided **out of the box**:
- Kubernetes
- Docker
- Terraform
- more coming soon
- Support custom policies
- Simple
- Specify only an image name, a directory containing IaC configs, or an artifact name
- See [Quick Start][quickstart]
- Fast
- The first scan will finish within 10 seconds (depending on your network). Consequent scans will finish in single seconds.
- Unlike other scanners that take long to fetch vulnerability information (~10 minutes) on the first run, and encourage you to maintain a durable vulnerability database, Trivy is stateless and requires no maintenance or preparation.
- Easy installation
- `apt-get install`, `yum install` and `brew install` is possible (See [Installation](installation.md))
- **No pre-requisites** such as installation of DB, libraries, etc.
- High accuracy
- **Especially Alpine Linux and RHEL/CentOS**
- Other OSes are also high
- DevSecOps
- **Suitable for CI** such as Travis CI, CircleCI, Jenkins, GitLab CI, etc.
- See [CI Example][integrations]
- Support multiple formats
- container image
- A local image in Docker Engine which is running as a daemon
- A local image in [Podman][podman] (>=2.0) which is exposing a socket
- A remote image in Docker Registry such as Docker Hub, ECR, GCR and ACR
- A tar archive stored in the `docker save` / `podman save` formatted file
- An image directory compliant with [OCI Image Format][oci]
- local filesystem
- remote git repository
Please see [LICENSE][license] for Trivy licensing information.

# Troubleshooting
## Scan
### Timeout
!!! error
``` bash
$ trivy image ...
...
analyze error: timeout: context deadline exceeded
```
Your scan may time out. Java takes a particularly long time to scan. Try increasing the value of the ---timeout option such as `--timeout 15m`.
### Certification
!!! error
Error: x509: certificate signed by unknown authority
`TRIVY_INSECURE` can be used to allow insecure connections to a container registry when using SSL.
```
$ TRIVY_INSECURE=true trivy image [YOUR_IMAGE]
```
### GitHub Rate limiting
!!! error
``` bash
$ trivy image ...
...
API rate limit exceeded for xxx.xxx.xxx.xxx.
```
Specify GITHUB_TOKEN for authentication
https://developer.github.com/v3/#rate-limiting
```
$ GITHUB_TOKEN=XXXXXXXXXX trivy alpine:3.10
```
### Running in parallel takes same time as series run
When running trivy on multiple images simultaneously, it will take same time as running trivy in series.
This is because of a limitation of boltdb.
> Bolt obtains a file lock on the data file so multiple processes cannot open the same database at the same time. Opening an already open Bolt database will cause it to hang until the other process closes it.
Reference : [boltdb: Opening a database][boltdb].
[boltdb]: https://github.com/boltdb/bolt#opening-a-database
## Homebrew
### Scope error
!!! error
Error: Your macOS keychain GitHub credentials do not have sufficient scope!
```
$ brew tap aquasecurity/trivy
Error: Your macOS keychain GitHub credentials do not have sufficient scope!
Scopes they need: none
Scopes they have:
Create a personal access token:
https://github.com/settings/tokens/new?scopes=gist,public_repo&description=Homebrew
echo 'export HOMEBREW_GITHUB_API_TOKEN=your_token_here' >> ~/.zshrc
```
Try:
```
$ printf "protocol=https\nhost=github.com\n" | git credential-osxkeychain erase
```
### Already installed
!!! error
Error: aquasecurity/trivy/trivy 64 already installed
```
$ brew upgrade
...
Error: aquasecurity/trivy/trivy 64 already installed
```
Try:
```
$ brew unlink trivy && brew uninstall trivy
($ rm -rf /usr/local/Cellar/trivy/64)
$ brew install aquasecurity/trivy/trivy
```
## Others
### Unknown error
Try again with `--reset` option:
```
$ trivy image --reset
```

`Trivy` (`tri` pronounced like **tri**gger, `vy` pronounced like en**vy**) is a simple and comprehensive [vulnerability][vulnerability]/[misconfiguration][misconf] scanner for containers and other artifacts.
A software vulnerability is a glitch, flaw, or weakness present in the software or in an Operating System.
`Trivy` detects vulnerabilities of [OS packages][os] (Alpine, RHEL, CentOS, etc.) and [language-specific packages][lang] (Bundler, Composer, npm, yarn, etc.).
In addition, `Trivy` scans [Infrastructure as Code (IaC) files][iac] such as Terraform and Kubernetes, to detect potential configuration issues that expose your deployments to the risk of attack.
`Trivy` is easy to use. Just install the binary and you're ready to scan.
All you need to do for scanning is to specify a target such as an image name of the container.

# vs Conftest
[Conftest][conftest] is a really nice tool to help you write tests against structured configuration data.
Misconfiguration detection in Trivy is heavily inspired by Conftest and provides similar features Conftest has.
This section describes the differences between Trivy and Conftest.

Trivy offers built-in policies and a variety of options, while Conftest only supports custom policies.
In other words, Conftest is simpler and lighter.
Conftest is a general testing tool for configuration files, and Trivy is more security-focused.
People who need an out-of-the-box misconfiguration scanner should use Trivy.
People who don't need built-in policies and write your policies should use Conftest.
[^1]: Pass only the types of configuration file as input, specified in selector
[^2]: To enrich the results such as ID, Title, Description, etc.
[^3]: Conftest supports [structured errors in rules][conftest-structured], but they are free format and not natively supported by Conftest.
[^4]: Trivy is not able to run `*_test.rego` like `conftest verify`.
[^5]: Dockerfile, HCL, HCL2, JSON, TOML, and YAML
[^6]: CUE, Dockerfile, EDN, HCL, HCL2, HOCON, Ignore files, INI, JSON, Jsonnet, TOML, VCL, XML, and YAML

# vs tfsec
[tfsec][tfsec] uses static analysis of your Terraform templates to spot potential security issues.
Trivy uses tfsec internally to scan Terraform HCL files, but Trivy doesn't support some features provided by tfsec.

tfsec is designed for Terraform.
People who use only Terraform should use tfsec.
People who want to scan a wide range of configuration files should use Trivy.

# Combined input
## Overview
Trivy usually scans each configuration file individually.
Sometimes it might be useful to compare values from different configuration files simultaneously.
When `combine` is set to true, all config files under the specified directory are combined into one input data structure.
!!! example
```
__rego_input__ := {
"combine": false,
}
```
In "combine" mode, the `input` document becomes an array, where each element is an object with two fields:
- `"path": "path/to/file"`: the relative file path of the respective file
- `"contents": ...`: the parsed content of the respective file
Now you can ensure that duplicate values match across the entirety of your configuration files.
## Return value
In "combine" mode, the `deny` entrypoint must return an object with two keys
`filepath` (required)
: the relative file path of the file being evaluated
`msg` (required)
: the message describing an issue
!!! example
```
deny[res] {
resource := input[i].contents
... some logic ...
res := {
"filepath": input[i].path,
"msg": "something bad",
}
}
```

# Custom Data
Custom policies may require additional data in order to determine an answer.
For example, an allowed list of resources that can be created.
Instead of hardcoding this information inside of your policy, Trivy allows passing paths to data files with the `--data` flag.
Given the following yaml file:
```bash
$ cd examples/misconf/custom-data
$ cat data/ports.yaml [~/src/github.com/aquasecurity/trivy/examples/misconf/custom-data]
services:
ports:
- "20"
- "20/tcp"
- "20/udp"
- "23"
- "23/tcp"
```
This can be imported into your policy:
```rego
import data.services
ports := services.ports
```
Then, you need to pass data paths through `--data` option.
Trivy recursively searches the specified paths for JSON (`*.json`) and YAML (`*.yaml`) files.
```bash
$ trivy conf --policy ./policy --data data --namespaces user ./configs
```

# Debugging policies
When working on more complex queries (or when learning Rego), it's useful to see exactly how the policy is applied.
For this purpose you can use the `--trace` flag.
This will output a large trace from Open Policy Agent like the following:
!!! tip
Only failed policies show traces. If you want to debug a passed policy, you need to make it fail on purpose.
```bash
$ trivy conf --trace configs/

# Examples
## Custom Policy
### Kubernetes
See [here][k8s].
The custom policy is defined in `user.kubernetes.ID001` package.
You need to pass the package prefix you want to evaluate through `--namespaces` option.
In this case, the package prefix should be `user`, `user.kuberntes`, or `user.kubernetes.ID001`.
### Dockerfile
See [here][dockerfile].
The input will be a dictionary of stages.
#### Single Stage
??? example
Dockerfile
```dockerfile
FROM foo
COPY . /
RUN echo hello
```
Rego Input
```json
{
"stages": {
"foo": [

### Docker Compose
See [here][compose].
Docker Compose uses YAML format for configurations. You can apply your Rego policies to `docker-compose.yml`.
### HCL
See [here][hcl].
Trivy parses HCL files and converts into structured data.
!!! warning
Terraform HCL files are not supported yet.
### Terraform Plan
See [here][tfplan].
Use the command [terraform show][terraform-show] to convert the Terraform plan into JSON so that OPA can read the plan.
```bash
$ terraform init
$ terraform plan --out tfplan.binary
$ terraform show -json tfplan.binary > tfplan.json
```
For more details, see also [OPA document][opa-terraform].
### Serverless Framework
See [here][serverless].
Server Framework uses YAML format for configurations. You can apply your Rego policies to `serverless.yaml`.
## Custom Data
See [here][data].
## Combined Input

# Custom Policies
## Overview
You can write custom policies in [Rego][rego].
Once you fisnish writing custom policies, you can pass the directory where those policies are stored with `--policy` option.
``` bash
trivy conf --policy /path/to/custom_policies --namespaces user /path/to/config_dir
```
As for `--namespaces` option, the detail is described as below.
### File formats
If a file name matches the following file patterns, Trivy will parse the file and pass it as input to your Rego policy.
| File format | File pattern |
| -------------- | ------------------------------------------------ |
| JSON | `*.json` |
| YAML | `*.yaml` |
| TOML | `*.toml` |
| HCL | `*.hcl`, `*.hcl1`, and `*.hcl2` |
| Dockerfile | `Dockerfile`, `Dockerfile.*`, and `*.Dockerfile` |
### Configuration languages
In the above general file formats, Trivy automatically identifies the following types of configuration files:
- Ansible (YAML)
- CloudFormation (JSON/YAML)
- Kubernetes (JSON/YAML)
This is useful for filtering inputs, as described below.
!!! warning
Custom policies do not support Terraform at the moment.
## Rego format
A single package must contain only one policy.
!!!example
``` rego
package user.kubernetes.ID001
__rego_metadata__ := {
"id": "ID001",
"title": "Deployment not allowed",
"severity": "LOW",
"type": "Custom Kubernetes Check",
"description": "Deployments are not allowed because of some reasons.",
}
__rego_input__ := {
"selector": [
{"type": "kubernetes"},
],
}
deny[msg] {
input.kind == "Deployment"
msg = sprintf("Found deployment '%s' but deployments are not allowed", [input.metadata.name])
}
```
In this example, ID001 "Deployment not allowed" is defined under `user.kubernetes.ID001`.
If you add a new custom policy, it must be defined under a new package like `user.kubernetes.ID002`.
### Policy structure
`package` (required)
: - MUST follow the Rego's [specification][package]
- MUST be unique per policy
- SHOULD include policy id for uniqueness
- MAY include the group name such as `kubernetes` for clarity
- Group name has no effect on policy evaluation
`__rego_metadata__` (optional)
: - SHOULD be defined for clarity since these values will be displayed in the scan results
`__rego_input__` (optional)
: - MAY be defined when you want to specify input format
`deny` (required)
: - SHOULD be `deny` or start with `deny_`
- Although `warn`, `warn_*`, `violation`, `violation_` also work for compatibility, `deny` is recommended as severity can be defined in `__rego_metadata__`.
- SHOULD return `string`
- Although `object` with `msg` field is accepted, other fields are dropped and `string` is recommended.
- e.g. `{"msg": "deny message", "details": "something"}`
### Package
A package name must be unique per policy.
!!!example
``` rego
package user.kubernetes.ID001
```
By default, only `appshield.*` packages will be evaluated.
If you define custom packages, you have to specify the package prefix via `--namespaces` option.
``` bash
trivy conf --policy /path/to/custom_policies --namespaces user /path/to/config_dir
```
In this case, `user.*` will be evaluated.
Any package prefixes such as `main` and `user` are allowed.
### Metadata
Metadata helps enrich Trivy's scan results with useful information.
!!!example
``` rego
__rego_metadata__ := {
"id": "ID001",
"title": "Deployment not allowed",
"severity": "LOW",
"type": "Custom Kubernetes Check",
"description": "Deployments are not allowed because of some reasons.",
"recommended_actions": "Remove Deployment",
"url": "https://cloud.google.com/blog/products/containers-kubernetes/kubernetes-best-practices-resource-requests-and-limits",
}
```
All fields under `__rego_metadata__` are optional.
| Field name | Allowed values | Default value | In table | In JSON |
| ------------------ | ------------------------------------| :-----------: | :----------------: |:---------------: |
| id | Any characters | N/A | :material-check: | :material-check: |
| title | Any characters | N/A | :material-check: | :material-check: |
| severity | `LOW`, `MEDIUM`, `HIGH`, `CRITICAL` | UNKNOWN | :material-check: | :material-check: |
| type | Any characters | N/A | :material-check: | :material-check: |
| description | Any characters | | :material-close: | :material-check: |
| recommended_actions| Any characters | | :material-close: | :material-check: |
| url | Any characters | | :material-close: | :material-check: |
Some fields are displayed in scan results.
``` bash
deployment.yaml (kubernetes)
============================
Tests: 28 (SUCCESSES: 14, FAILURES: 14, EXCEPTIONS: 0)
Failures: 14 (HIGH: 1)
+---------------------------+------------+-------------------------------------+----------+------------------------------------------+
| TYPE | MISCONF ID | CHECK | SEVERITY | MESSAGE |
+---------------------------+------------+-------------------------------------+----------+------------------------------------------+
| Custom Kubernetes Check | ID001 | Deployment not allowed | LOW | Found deployment 'test' but deployments |
| | | | | are not allowed |
+---------------------------+------------+-------------------------------------+----------+------------------------------------------+
```
### Input
You can specify input format via `__rego_input__`.
All fields under `__rego_input` are optional.
!!!example
``` rego
__rego_input__ := {
"combine": false,
"selector": [
{"type": "kubernetes"},
],
}
```
`combine` (boolean)
: The details is [here](combine.md).
`selector` (array)
: This option filters the input by file formats or configuration languages.
In the above example, Trivy passes only Kubernetes files to this policy.
Even if Dockerfile exists in the specified directory, it will not be passed to the policy as input.
When configuration language such as Kubernetes is not identified, file format such as JSON will be used as `type`.
When configuration language is identified, it will overwrite `type`.
!!! example
`pod.yaml` including Kubernetes Pod will be handled as `kubernetes`, not `yaml`.
`type` is overwritten by `kubernetes` from `yaml`.
`type` accepts `kubernetes`, `dockerfile`, `ansible`, `cloudformation`, `json`, `yaml`, `toml`, or `hcl`.

# Testing
It is highly recommended to write tests for your custom policies.
## Rego testing
To help you verify the correctness of your custom policies, OPA gives you a framework that you can use to write tests for your policies.
By writing tests for your custom policies you can speed up the development process of new rules and reduce the amount of time it takes to modify rules as requirements evolve.
For more details, see [Policy Testing][opa-testing].
!!! example
```
package user.dockerfile.ID002
test_add_denied {
r := deny with input as {"stages": {"alpine:3.13": [
{"Cmd": "add", "Value": ["/target/resources.tar.gz", "resources.jar"]},
{"Cmd": "add", "Value": ["/target/app.jar", "app.jar"]},
]}}
count(r) == 1
r[_] == "Consider using 'COPY /target/app.jar app.jar' command instead of 'ADD /target/app.jar app.jar'"
}
```
To write tests for custom policies, you can refer to existing tests under [AppShield][appshield].
## Go testing
[Fanal][fanal] which is a core library of Trivy can be imported as a Go library.
You can scan config files in Go and test your custom policies using Go's testing methods, such as [table-driven tests][table].
This allows you to use the actual configuration file as input, making it easy to prepare test data and ensure that your custom policies work in practice.
In particular, Dockerfile and HCL need to be converted to structural data as input, which may be different from the expected input format.
!!! tip
We recommend writing OPA and Go tests both since they have different roles, like unit tests and integration tests.
The following example stores allowed and denied configuration files in a directory.
`Successes` contains the result of successes, and `Failures` contains the result of failures.
``` go
{
name: "disallowed ports",
input: "configs/",
fields: fields{
policyPaths: []string{"policy"},
dataPaths: []string{"data"},
namespaces: []string{"user"},
},
want: []types.Misconfiguration{
{
FileType: types.Dockerfile,
FilePath: "Dockerfile.allowed",
Successes: types.MisconfResults{
{
Namespace: "user.dockerfile.ID002",
PolicyMetadata: types.PolicyMetadata{
ID: "ID002",
Type: "Docker Custom Check",
Title: "Disallowed ports exposed",
Severity: "HIGH",
},
},
},
},
{
FileType: types.Dockerfile,
FilePath: "Dockerfile.denied",
Failures: types.MisconfResults{
{
Namespace: "user.dockerfile.ID002",
Message: "Port 23 should not be exposed",
PolicyMetadata: types.PolicyMetadata{
ID: "ID002",
Type: "Docker Custom Check",
Title: "Disallowed ports exposed",
Severity: "HIGH",
},
},
},
},
},
},
```
`Dockerfile.allowed` has one successful result in `Successes`, while `Dockerfile.denied` has one failure result in `Failures`.

# Filesystem
## Quick start
Trivy scans a filesystem such as a virtual machine to detect misconfigurations.
You have to specify `--security-checks config` to enable misconfiguration detection.
```bash
$ trivy fs --security-checks config /path/to/dir
```
Internally, it is the same as [config subcommand](iac.md).
## Vulnerability and Misconfiguration scanning
The difference between `fs` and `config` subcommand is that `fs` can detect both vulnerabilities and misconfiguration at the same time.
You have to specify `--security-checks vuln,config` to enable vulnerability and misconfiguration detection.
``` bash
$ ls myapp/
Dockerfile Pipfile.lock
$ trivy fs --security-checks vuln,config --severity HIGH,CRITICAL myapp/
