Configuration of custom github labels for runners

[ebellefontaine]

Is there a way to configure custom github labels for runners at startup time. I'm currently installing this via helm chart, but didn't see anything immediately apparent on how to configure those custom github labels. I could go and add the label via the UI in github to a runner, but I'd rather have the labels automatically created based on what K8s cluster I have the github operator running. Wasn't sure if this was something that was already setup in this operator and can be easily configured, or not.

Yes, you can declare the pool like this (notice ACTIONS_RUNNER_INPUT_LABELS env var):

apiVersion: "garo.tietoevry.com/v1alpha1"
kind: GithubActionRunner
metadata:
  namespace: github-actions-runner
  name: default-pool
spec:
  # minimum amount of runners that should be available
  minRunners: 1
  # maximum amount of runners that should be available
  maxRunners: 9
  # the GitHub organization name, from https://github.com/yourGithubOrgId
  organization: XXX
  # reference to secret in same namespace containing the token for GitHub, needs org-level scope
  tokenRef:
    # name of secret
    name: github-token
    # key within secret holding the value
    key: GH_TOKEN
  reconciliationPeriod: "1m"
  # a podspec like you wish for the runners.
  # the spec here will run the one from https://github.com/evryfs/github-actions-runner as the runner,
  # with a companion dind (Docker In Docker) container.
  podTemplateSpec:

Thanks!

Is this option ACTIONS_RUNNER_INPUT_LABELS deprecated?
Seems like it was deleted in one of the recent builds.

UPD: The feature still working if you add this.

@davidkarlsen please bring it back in a future releases
