For instance, the following instructs +SAST to pull `my-docker-registry/gl-images/bandit` +instead of `registry.gitlab.com/gitlab-org/security-products/analyzers/bandit`. +In `.gitlab-ci.yml` define: + +```yaml +include: + template: SAST.gitlab-ci.yml + +variables: + SAST_ANALYZER_IMAGE_PREFIX: my-docker-registry/gl-images +``` + +This configuration requires that your custom registry provides images for all +the official analyzers. + +### Selecting specific analyzers + +You can select the official analyzers you want to run.
