Running a Cassandra cluster in Kubernetes

In this section, we will explore in detail a very large example of configuring a Cassandra cluster to run on a Kubernetes cluster. I will dissect and give some context for interesting parts. If you wish to explore this even further, the full example can be accessed here:
