Persistence

So we've gone as far as we can with our cluster, without any form of persistence. As soon as we want to retain data, be it a database, metrics history, or objects, we need one or more ways to persist data within the cluster.

Here are some popular options, ranked in difficulty/complexity, in vaguely ascending order:

• Local Path Provisioner (on k3s)
• TopoLVM
• OpenEBS (coming soon)
• Rook Ceph (coming soon)
• Longhorn (coming soon)
