Goodbye Etcd, Hello PostgreSQL: Running Kubernetes with an SQL Database

Sometimes you don't need to make your entire infra distributed, just parts of it. I'm comfortable having my cluster's database be something like RDS while I benefit from the distributed nature of the compute I get from k8s.

I've stood up multiple k8s cluster, and so far the most fickle component is ETCD. My last cluster is k3s on Postgres, and has been running in production for a very long time with very little babysitting.

Next I'll experiment with SQLite.

k3s started with sqlite and moved to etcd so I'd start with finding out why in that case

k3s still uses SQLite - or Postgres. It just also can run etcd.
