While attempting to deploy an awesome set-it-and-forget-it volume snapshot solution for my GKE cryptocurrency mining pool empire, I stumbled across the following error when trying to create the necessary RBAC ClusterRoleBinding:
$ kubectl apply -f rbac.yaml
serviceaccount "k8s-snapshots" unchanged
clusterrolebinding.rbac.authorization.k8s.io "k8s-snapshots" configured
