I'm not able to delete one of the replication controller no matter what, seems like it is corrupted as it is affecting some components.
kubectl delete rc kube-dns-v20 --namespace=kube-system
error: timed out waiting for "kube-dns-v20" to be syncedTried with several options like cascade=false, it says deleted, when actually it is not deleting it.
kubectl delete rc kube-dns-v20 --namespace=kube-system --force=true --cascade=false
replicationcontroller "kube-dns-v20" deletedAny other way in which this can be done?
I had a similar issue. Have you tried deleting the associated "deploymentconfig"? You can find it with kubectl get dc and then delete with kubectl delete dc <name>.
Attempt setting the grace-period to 0?
kubectl delete rc kube-dns-v20 --force=true --grace-period=0 --namespace=kube-system
