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 :latest tag resolves to. Surprisingly, there doesn't seem to be an off-the-shelf solution for that...

I don't do a great job of this, but take Immich for example. There, I specify the version in the compose.yml (technically, the version is in the .env file and substituted into the compose.yml). At that point, updating Immich is a matter of updating the version number and restarting the service.

These configuration files are all managed with git, so when I do these updates, I create a new commit. I just checked, and I have Forgejo pinned to a specific version in its compose.yml as well. But unfortunately, the other services are referencing :latest. I'm going to go back and pin them all :)

I built a small tool that does that for me now and published it: https://feddit.de/post/2909288 maybe you'll find it useful, no guarantee that it doesn't break something though :D

How do you do that? I'm building a similar system now that automatically updates my containers. I've played around with the API and I can see which versions are attached to the latest sha265, but I can't find a way to automatically tell which version it is. Especially when the same sha is linked to multiple versions

I only keep track of the sha256, compose happily uses those. I published the tool https://feddit.de/post/2909288 :)

Ah ok. I thought you meant the numbered version. I'm doing the same with sha256 too.
