Run DAST in an offline environment

DETAILS: Tier: Ultimate Offering:, Self-managed, GitLab Dedicated

For self-managed GitLab instances in an environment with limited, restricted, or intermittent access to external resources through the internet, some adjustments are required for the DAST job to successfully run. For more information, see Offline environments.

Requirements for offline DAST support

To use DAST in an offline environment, you need:

GitLab Runner has a default pull policy of always, meaning the runner tries to pull Docker images from the GitLab container registry even if a local copy is available. The GitLab Runner pull_policy can be set to if-not-present in an offline environment if you prefer using only locally available Docker images. However, we recommend keeping the pull policy setting to always if not in an offline environment, as this enables the use of updated scanners in your CI/CD pipelines.

Make GitLab DAST analyzer images available inside your Docker registry

For DAST, import the following default DAST analyzer image from to your local Docker container registry:


The process for importing Docker images into a local offline Docker registry depends on your network security policy. Consult your IT staff to find an accepted and approved process by which external resources can be imported or temporarily accessed. These scanners are periodically updated with new definitions, and you may be able to make occasional updates on your own.

For details on saving and transporting Docker images as a file, see the Docker documentation on docker save, docker load, docker export, and docker import.

Set DAST CI/CD job variables to use local DAST analyzers

Add the following configuration to your .gitlab-ci.yml file. You must replace image to refer to the DAST Docker image hosted on your local Docker container registry:

  - template: DAST.gitlab-ci.yml

The DAST job should now use local copies of the DAST analyzers to scan your code and generate security reports without requiring internet access.

Alternatively, you can use the CI/CD variable SECURE_ANALYZERS_PREFIX to override the base registry address of the dast image.
