This isn't a direct answer to your questions but you might be interested in the Kubernetes operator for Apache Cassandra [1] from DataStax. You can use the cass-operator to deploy a C* 3.11.6 image to your Kubernetes cluster. The docs are available here [2].
FWIW there are several other published operators from the likes of Orange [3] and Instaclustr [4]. The authors have come together in the community to contribute their work and "combine" them into an "official" operator for Cassandra. (I'm sure someone will correct me if I've made any misrepresentation). Cheers!
