Finalization of pods not run when CR is deleted
Running kubectl apply -f .\gh-runners-linux.yaml creates the runners as expected in my GitHub organization. When I delete them though (using kubectl delete -f .\gh-runners-linux.yaml), the pods that contained the runners get stuck in a "Terminating" status.
NAMESPACE NAME READY STATUS RESTARTS AGE
github-action-runners runner-pool-pod-fhthp 0/3 Terminating 0 4m50s
github-action-runners runner-pool-pod-wfs62 0/3 Terminating 0 4m50s
github-actions-runner-operator github-actions-runner-operator-59b9d486b5-t2p62 1/1 Running 0 5m26s
If I edit the pod and remove the finalizer (garo.tietoevry.com/runner-registration), the pod successfully deletes after saving that change. The runner is not being removed from my list of GitHub self hosted runners though as I would expect. Am I missing something here?
Then there is a problem with unregistration, please provide logs from the operator to enable me to help you.
@davidkarlsen I don't see any mention of the delete in the operator log. The delete command was issued at 12:34:23 which is the last time there is anything in the operator logs here:

Sorry, I just noticed I put this on the wrong project. This should probably be on the github-actions-runner-operator project than here. Let me know if you want me to move it.
that's strange, what version are you running of the operator? can you provide the CR for the runner pool?
I'm running the latest version from helm charts 2.5.10. I'm just testing locally in my k8s environment in docker on win10.

I was able to reproduce it. It's an edge case when you delete the actual cr. In this case it's gone and the cleanup step handling the finalization https://github.com/evryfs/github-actions-runner-operator/blob/master/controllers/githubactionrunner_controller.go#L116 is not reached.

K8S operator for scheduling github actions runner pods - evryfs/github-actions-runner-operator
Hi there, I have the same issue here
NAME READY STATUS RESTARTS AGE
runner-pool-pod-7qhqc 0/3 Terminating 0 4d6h
runner-pool-pod-d96bw 0/3 Terminating 0 4h38m
runner-pool-pod-w278v 0/3 Terminating 0 4h38m
runner-pool-pod-xbmww 0/3 Terminating 0 4h47m
I can't remove them. Thank you.
@aroemen @duyhenryer I was able to delete them by removing the finalizers field. Patch the finalizers list to be null:
kubectl patch pod <POD_NAME> -n <NAMESPACE> -p '{"metadata":{"finalizers":null}}'
yes, and that's what the operator does after de-registering them from github - which is why I am curious what the operator logs.
@davidkarlsen I posted the operator logs back in March. Do you need additional data?
@aroemen sorry, commented on the wrong issue, I was thinking of https://github.com/evryfs/github-actions-runner-operator/issues/232 which was fixed recently. Still need this to fix this one (deleting CR)
@aroemen #264 will solve this, as you can scale the pool to zero, then delete the CR.
I'm trying to make this work on latest build but cant seem to make it...
$ kubectl patch githubactionrunners.garo.tietoevry.com runner-pool --namespace actions-runner --patch '{"spec":{"minRunners":0}}' --type=merge
Results in
The GithubActionRunner "runner-pool" is invalid: spec.minRunners: Invalid value: 0: spec.minRunners in body should be greater than or equal to 1
I suspect that either the image i'm pulling is not the latest - or i'm pulling the image wrong, the operator image i'm pulling using the published helm charts :
helm upgrade --install --wait github-actions-runner-operator evryfs-oss/github-actions-runner-operator --namespace actions-runner-operator --set githubapp.existingSecret=github-runner-app --set githubapp.enabled=true
The runner image is this one :
quay.io/evryfs/github-actions-runner:latest
What am i missing ?
Thx Tony
@tonywildey-valstro you probably don't have the lastest crd: https://raw.githubusercontent.com/evryfs/github-actions-runner-operator/v0.10.0/config/crd/bases/garo.tietoevry.com_githubactionrunners.yaml

Ah - there we go - I installed using the helm chart: https://github.com/evryfs/helm-charts/blob/master/charts/github-actions-runner-operator/crds/garo.tietoevry.com_githubactionrunners.yaml which does not have the min runners change
