I connected my existing kubernetes cluster to gitlab using the gitlab integration in myproject/operations/kubernetes on the left tab pane in the gitlab gui.
After having installed helm + gitlab runner from the gitlab GUI applications, the new gitlab runner is visible in the project runners.
What I don't understand from the gitlab documentation is how do you modify the new runner's configuration. You cannot use the gitlab-runner cli, like for a non-kubernetes runner, because the runner in running in a pod, not on the host machine, right?
I am not sure which part of the runner doc applies to my case. What to use if I wanted to make the runner use another executor or build from another image ? (default image of the pod is ubuntu 16 for me).
If you have already installed and configured a runner installed this way, from the GUI, please tell me how. Thank you.
