Using a local Github runner

  • Settings > actions > runners > new self-hosted runner

  • Create the Dockerfile
    Note we're setting up the container to use docker-in-docker with the host's Docker
    Alternative: install docker in the image

    $ mkdir runner-github
$ cd runner-github

# Create docker-compose.yml with the appropriate version
# Copy the command in Github's "download" section
$ curl="curl -o actions-runner-linux-x64-2.315.0.tar.gz -L https://github.com/actions/runner/releases/download/v2.315.0/actions-runner-linux-x64-2.315.0.tar.gz"

$ version=$([[ "${curl##*-}" =~ (\.?[0-9])* ]] && echo $BASH_REMATCH)
$ echo $version
2.315.0

$ docker_group=$(getent group docker | cut -d: -f3)
$ echo $docker_group

  • Build and launch

    # Build the image
docker-compose build

# Copy the command in Github's "configure" section
docker-compose run runner ./config.sh --url https://github.com/a-mt/gcp-gke-django --token AAIK6BREEMCZLYP23CIDL7LGD6H24

# Run
docker-compose up

    If your config.sh gives you "Http response code: NotFound from 'POST https://api.github.com/actions/runner-registration'": the token has expired, refresh the "new self-hosted runner" page to get a new token

  • Check that your runner is listed in the runners list and is "idle":
