I set up a new home server recently using containerized services, and I wanted to share what I learned. Nothing here is revolutionary, but this is the type of resource I wish I had when I started.
I’m open to feedback on what I could have done better!
Do you do some sort of versioning/snapshotting of your services? I’m on the compose route as well, and have one btrfs subvolume per service that holds the compose.yml and all bind-mounted folders for perstistent data. That again gets regularly snapshotted by snapper.
What leaves me a bit astounded is, that nobody seems to version the containers they are running. But without that, rolling back if something breaks might become a game of guessing the correct container version. I started building a tool that snapshots a service, then rewrites the
image:in compose.yml to reflect what ever the current:latesttag resolves to. Surprisingly, there doesn’t seem to be an off-the-shelf solution for that…
