Step 1 – Install Latest Version of Docker

Step 2 – Run “gitlab-runner” command in the container

# Use local system volume mounts to start the Runner container

$ docker run -d --name gitlab-runner --restart always \
  -v /srv/gitlab-runner/config:/etc/gitlab-runner \
  -v /var/run/docker.sock:/var/run/docker.sock \
  gitlab/gitlab-runner:latest

$ docker logs gitlab-runner

Step 3 – Register the runner

The following steps describe launching a short-lived gitlab-runner container to register the container you created during install. After you finish registration, the resulting configuration is written to your chosen configuration volume (for example, /srv/gitlab-runner/config) and is loaded by the runner using that configuration volume.

To register a runner using a Docker container: Run the register command based on the mount type:

$ docker run --rm -it -v /srv/gitlab-runner/config:/etc/gitlab-runner gitlab/gitlab-runner register


- Enter your GitLab instance URL (also known as the gitlab-ci coordinator URL).
- Enter the token you obtained to register the runner.
- Enter a description for the runner. You can change this value later in the GitLab user interface.
- Enter the tags associated with the runner, separated by commas. You can change this value later in the GitLab user interface.
- Enter any optional maintenance note for the runner.
- Provide the runner executor. For most use cases, enter docker.
- If you entered docker as your executor, you are asked for the default image to be used for projects that do not define one in .gitlab-ci.yml.
