Use GitLab as a microservice

DETAILS: Tier: Free, Premium, Ultimate Offering: SaaS, self-managed

Many applications need to access JSON APIs, so application tests might need access to APIs too. The following example shows how to use GitLab as a microservice to give tests access to the GitLab API.

  1. Configure a runner with the Docker or Kubernetes executor.

  2. In your .gitlab-ci.yml add:

      - name: gitlab/gitlab-ce:latest
        alias: gitlab
      GITLAB_HTTPS: "false"             # ensure that plain http works
      GITLAB_ROOT_PASSWORD: "password"  # to access the api with user root:password

NOTE: Variables set in the GitLab UI are not passed down to the service containers. For more information, see GitLab CI/CD variables.

Then, commands in script sections in your .gitlab-ci.yml file can access the API at http://gitlab/api/v4.

For more information about why gitlab is used for the Host, see How services are linked to the job.

You can also use any other Docker image available on Docker Hub.

The gitlab image can accept environment variables. For more details, see the Omnibus documentation.
