Liste des variables prédéfinies dans GitLab. C'est très utile pour déclencher des "when event".

Voici le script Ansible :

- name: List configured runners
  command: gitlab-runner list
  register: configured_runners
  changed_when: False

- name: Register runner to GitLab
  command: gitlab-runner register >
    --non-interactive
    --url '{{ gitlab_runner_coordinator_url }}'
    --registration-token '{{ gitlab_runner_registration_token }}'
    --description '{{ gitlab_runner_description }}'
    --tag-list '{{ gitlab_runner_tags | join(",") }}'
    --executor '{{ gitlab_runner_executor }}'
    --docker-image '{{ gitlab_runner_docker_image }}'
when: configured_runners.stderr.find('\n{{ gitlab_runner_description }}') == -1

Hors Ansible :

gitlab-runner register \
              --non-interactive \
              --url 'https ://${GITLAB_HOST}:${GITLAB_PORT}/ci' \
              --registration-token 'Yy1YWzcDVyBbc9RNGxsb' \
              --description 'Mon GitLab Runner' \
              --tag-list 'java php nodejs' \
              --executor 'shell'
#              --docker-image '{{ gitlab_runner_docker_image }}'
