tl;dr - I thought I needed PersistentVolumes but I don’t (I do go through how to use/activate them though), they solve a different problem. All I needed was the combination of a Volume + StatefulSet + Node Affinity + Service in order to get my database running on a single node consistently, and accessible through DNS. I also go through setting up High Availability (HA)/clustered RethinkDB but it’s probably wrong/not axiomatic Kubernetes so check out the section on why I think it’s wrong.
