Finally, let’s create a Cassandra cluster as a Kubernetes statefulset object. Doing that does not delete or stop the pods or the the PVCs - those will re-attach to the new statefulset spun up later, so you won't lose anything. There is a discussion on one of the OpenShift/Kubernetes task trackers (which I cannot find anymore) that explains the rationale: in contrast with stateless Deployments, where OpenShift can simply scale up a new set of pods, then scale down the old one, while routing traffic to the new one, this is not easily possible with statefulsets, since those have persistent PVCs, so there usually is a very defined number of pods that can/should run at a time. If used in a local binding, an admin user will have rights to view any resource in the project and modify any resource in the project except for quota.
