Kubernetes was not initially designed with persistence in mind. If it was then the etcd of the master nodes would also be in containers.

There are (good) attempts at shoving it in, but the general advice I would give is that if you care about your data you should give it every possible chance for to not be corrupted or disrupted; and that means keeping the number of abstractions and indirections low.

Everything comprising control plane runs in a container including etcd, apiserver, kube-controller and scheduler
