I'm using compose wrong and I know it. (lemmy.one)

For the last two years, I've been treating compose files as individual runners for individual programs.

Then I brainstormed the concept of having one singular docker-compose file that writes out every single running container on my system... (that can use compose), each install starts at the same root directory and volumes branch out from there.

Then I find out, this is how most people use compose. One compose file, with volumes and directories branching out from wherever ./ is called.

THEN I FIND OUT... that most people that discover this move their installations to podman because compose works on different versions per app and calling those versions breaks the concept of having one singular docker-compose.yml file and podman doesn't need a version for compose files.

Is there some meta for the best way to handle these apps collectively?

The best way is to use Podman's Systemd integration.

This is what I use whenever I make my own services or am using a simple service with only one container. But I have yet to figure out how to convert a more complicated service like lemmy that already uses docker-compose, so I just use podman-docker and emulate docker-compose with podman. But that doesn't get me any of the benefits of systemd and now my podman has a daemon, which defeats one of the main purposes of podman.

You can use podman pods and generate the systemd file for the whole pod.

But how do I convert the docker-compose file to a pod definition? If I have to do it manually, that's a pass because I don't want to do it again if lemmy updates and significantly changes it's docker-compose file, which it did when 0.18.0 came out.
