I've deleted an L7 ingress in Google Container Engine (Kubernetes v1.4.5) via the following command: kubectl delete -f l7-ingress.yaml. However, resources still linger, including its backend services so that I cannot recreate the ingress because my quota for backend services (3) is reached. Even after deleting the GKE cluster in question, the backend services and instance groups linger.
If I try to delete one of the backend services via gcloud the following happens:
$ gcloud compute backend-services delete k8s-be-31917--0901b0d0f6edfe9d
The following backend services will be deleted:
- [k8s-be-31917--0901b0d0f6edfe9d]
ERROR: (gcloud.compute.backend-services.delete) Some requests did not succeed:
- The backend_service resource 'k8s-be-31917--0901b0d0f6edfe9d' is already being used by 'k8s-um-default-l7-ingress--0901b0d0f6edfe9d'Moreover, if I try to delete one of the instance groups created by the ingress from the Google Cloud Console, an "undefined" error is reported in a dialog.
How do I remove all resources associated with an L7 ingress in Google Container Engine??
Maybe this changed from few months ago, when I was using GCE, but I remember it was not allowed to delete the L7 LB. Instead you can scale it to 0.
kubectl scale rc l7-lb-controller --replicas=0 --namespace=kube-system
