WARNING:
GitLab 14.0 will replace its container scanning engine with Trivy. Currently, GitLab uses the open
source Clair engine for container scanning. GitLab 13.9 deprecates Clair. This is not a hard
breaking change, as customers who wish to continue to use Clair can do so by setting the
`CS_MAJOR_VERSION` CI/CD variable to version 3 (or earlier) in their `gitlab-ci.yaml` file. Since Clair is
deprecated, however, note that GitLab will no longer update or maintain that scanning engine
beginning in the 14.0 release. We advise customers to use the new default of Trivy beginning in
GitLab 14.0 for regular updates and the latest features.

moving from Clair to Trivy.
Your application's Docker image may itself be based on Docker images that contain known
vulnerabilities. By including an extra job in your pipeline that scans for those vulnerabilities and
displays them in a merge request, you can use GitLab to audit your Docker-based apps.
By default, container scanning in GitLab is based on [Clair](https://github.com/quay/clair) and
[Klar](https://github.com/optiopay/klar), which are open-source tools for vulnerability static analysis in
containers. The GitLab [Klar analyzer](https://gitlab.com/gitlab-org/security-products/analyzers/klar/)
scans the containers and serves as a wrapper for Clair.
To integrate security scanners other than Clair and Klar into GitLab, see

If you want to override the job definition (for example, to change properties like `variables`), you
must declare a `container_scanning` job after the template inclusion, and then
specify any additional keys. For example:
must declare and override a job after the template inclusion, and then
specify any additional keys.
This example sets `GIT_STRATEGY` to `fetch` to be considered by both Klar and Container-Scanning:
```yaml
include:
- template: Container-Scanning.gitlab-ci.yml
container_scanning:
.cs_common:
variables:
GIT_STRATEGY: fetch
```
This example sets `KLAR_TRACE` to `true`, which is specific to Klar:
```yaml
include:
- template: Container-Scanning.gitlab-ci.yml
container_scanning:
variables:
CLAIR_TRACE: true
```
This example sets `TRIVY_DEBUG` to `true`, which is specific to Container-Scanning:
```yaml
include:
- template: Container-Scanning.gitlab-ci.yml
container_scanning_new:
variables:
TRIVY_DEBUG: true
```
WARNING:
GitLab 13.0 and later doesn't support [`only` and `except`](../../../ci/yaml/README.md#onlyexcept-basic).
When overriding the template, you must use [`rules`](../../../ci/yaml/README.md#rules)
instead.
### Migrating from Clair to Trivy
If you are currently using Clair and want to migrate to Trivy before GitLab 14.0, you can do so by
taking the following steps:
1. Take the following actions in your CI file:
- Set the variable `CS_MAJOR_VERSION` to `4`. The job scope is global variables, or under `.cs_common`.
- Remove the variable `CS_PROJECT` from your CI file. The job scope is `container_scanning_new`.
Setting this variable to `container-scanning` under the correct scope has the same effect as
removing it from your CI file.
- Remove the `CS_ANALYZER_IMAGE` variable from your CI file. The job scope is `.cs_common`. Note
that instead of overriding this variable, you can use `CS_MAJOR_VERSION`.
1. Remove any variables that are only applicable to Klar. For a complete list of these variables,
see the [available variables](#available-variables).
1. Make any [necessary customizations](#customizing-the-container-scanning-settings) to the
`Container-Scanning` scanner. We strongly recommended that you minimize customizations, as they
might require changes in future GitLab major releases.
**Troubleshooting**
Prior to the GitLab 14.0 release, any variable defined under the scope `container_scanning` is not
considered for Container-Scanning. Verify that all variables for the Container-Scanning analyzer are
either defined as a global variable, or under `.cs_common` and `container_scanning_new`.
### Using a custom SSL CA certificate authority
You can use the `ADDITIONAL_CA_CERT_BUNDLE` CI/CD variable to configure a custom SSL CA certificate authority, which is used to verify the peer when fetching Docker images from a registry which uses HTTPS. The `ADDITIONAL_CA_CERT_BUNDLE` value should contain the [text representation of the X.509 PEM public-key certificate](https://tools.ietf.org/html/rfc7468#section-5.1). For example, to configure this value in the `.gitlab-ci.yml` file, use the following:

against a Docker container without needing to run it within the context of a CI job. To scan an
image directly, follow these steps:
1. Run [Docker Desktop](https://www.docker.com/products/docker-desktop)
or [Docker Machine](https://github.com/docker/machine).
1. Run the analyzer's Docker image, passing the image and tag you want to analyze in the
`CI_APPLICATION_REPOSITORY` and `CI_APPLICATION_TAG` variables:
```shell
docker run \
--interactive --rm \
--volume "$PWD":/tmp/app \
-e CI_PROJECT_DIR=/tmp/app \
-e CI_APPLICATION_REPOSITORY=registry.gitlab.com/gitlab-org/security-products/dast/webgoat-8.0@sha256 \
-e CI_APPLICATION_TAG=bc09fe2e0721dfaeee79364115aeedf2174cce0947b9ae5fe7c33312ee019a4e \
registry.gitlab.com/gitlab-org/security-products/analyzers/container-scanning
```
The results are stored in `gl-container-scanning-report.json`.
