i am using nfs and i think its pretty simple and just works

It's simple enough, and I moved from Longhorn to NFS for my homelab as well, but I bristle at needing to have the same unix UIDs everywhere that wants to mount or serve an NFS volume. It seems like a huge layering violation.

I "just" want to expose storage over the network (I don't really care about the protocol, NFS would be fine) with a pre-shared secret or something like that.

edit: NFS really goes poorly when containers want to chown things, now I need to have a 'postgres' UID that's the same everywhere?
