I want to install the GitLab runner version 10.8.7 so that it matches the same version as the GitLab installation that I'm using. I tried to figure out the helm chart version with the following command:
helm search repo -l gitlab/gitlab-runner
NAME CHART VERSION APP VERSION DESCRIPTION
gitlab/gitlab-runner 0.15.0 12.9.0 GitLab Runner
...
gitlab/gitlab-runner 0.1.45 11.7.0 GitLab Runner
gitlab/gitlab-runner 0.1.44 GitLab Runner
gitlab/gitlab-runner 0.1.43 GitLab Runner
gitlab/gitlab-runner 0.1.42 GitLab Runner
gitlab/gitlab-runner 0.1.41 GitLab Runner
...
gitlab/gitlab-runner 0.1.14 GitLab Runner
gitlab/gitlab-runner 0.1.13 GitLab Runner
but it seems that only chart versions 0.15 to 0.14.5 specify the actual GitLab version (12.9.0 to 11.7.0).
So what chart version corresponds to app version GitLab 10.8.7?
