Cool idea with that thread series! I tried a similar thing with the Selfhosting Sunday posts and I always enjoy seeing what everyone’s up to.

I’ve been running Docker containers on plain Linux (Debian mostly) for a long time (and native a pplications before but I’m glad I migrated most of it) but last year I switched to Proxmox for my own hardware. I was mostly interested in the super comfortable automated VM snapshots but after adding a second node I’m also glad to have High Availability. To maintain a proper quorum (have at least 3 nodes for decisions) I run corosync on a Raspi. It’s been super reliable once set up properly. I have a NAS for backups/snapshots which is native TrueNAS (it was simply the best GUI for ZFS and NFS).

Thought back and forth about setting up K3S and migrate everything but I decided it’s not worth the effort and would just be for practice, but I can’t be arsed to set it up just for that. (I do K8S at work but we have managed clusters so barely any low level tinkering).
