Use your own runner from a dedicated VM
In this section we will add a dedicated GitLab runner to the CI/CD infrastructure. The runner will execute inside a docker container.
- Create the docker volume:
docker volume create gitlab-runner-config -
Start the GitLab runner container using the volume we have just created:
Check your container is running:docker run -d --name gitlab-runner --restart always \ -v /var/run/docker.sock:/var/run/docker.sock \ -v gitlab-runner-config:/etc/gitlab-runner \ gitlab/gitlab-runner:latestdocker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 94f0a1bdc4de gitlab/gitlab-runner:latest "/usr/bin/dumb-init …" 6 minutes ago Up 5 minutes gitlab-runner -
Register the runner
- Obtain a token:
Visit your project web page (at
https://baltig.infn.it/USERNAME/tutorial-ci) and go to Settings > CI/CD and expand the Runners section:
Click "New project runner" under the section Project runners:
Select the option "Run untagged jobs" as shown in the next figure:
Copy the token displayed in step 1:
- Launch the following command replacing the
***********with the token you have just copied:If the registration is successful you will get a similar message:docker exec -it gitlab-runner gitlab-runner register -n --url https://baltig.infn.it \ --token *********** --description "My Docker Runner" \ --executor docker --docker-image "docker:latest" \ --docker-volumes /var/run/docker.sock:/var/run/docker.sockYou will see the message about the successful registration also in the web page:Runtime platform arch=amd64 os=linux pid=16 revision=8ec04662 version=16.3.0 Running in system-mode. Verifying runner... is valid runner=5sYMm3yvH Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded! Configuration (with the authentication token) was saved in "/etc/gitlab-runner/config.toml"
and your runner will appear under the specific runners of the project:

Visit your project web page (at
Now you can disable the shared runners and use your newly created one:
Let's trigger our pipeline. You can commit a change in your repository or trigger it manually from CI/CD > Pipelines:
You can also look at the runner logs using the command docker logs gitlab-runner:
docker logs -f gitlab-runner
