Only first Docker volume added to runner configuration

[joelpet]

The following vars definition

gitlab_runner_docker_volumes:                  
  - "/cache"                                   
  - "/tmp"

results in a registration command like this:

gitlab-runner register ... --docker-volumes "/cache" "/tmp" ...

which does not seem to have the expected result—i.e. only /cache is being added as a volume in /etc/gitlab-runner/config.toml instead of both /cache and /tmp.

With the following code in place at

ansible-gitlab-runner/tasks/register-runner.yml

Line 19 in 7739185

{% if gitlab_runner_docker_volumes is defined %}

it works as expected (both volumes show up in config.toml):

    {% for volume in gitlab_runner_docker_volumes | default([]) %}
    --docker-volumes "{{ volume }}"
    {% endfor %}
