Comment on I'm using compose wrong and I know it.

  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.

    Just forget about podman-compose and use simple Quadlet container files with Systemd. That way it is not all in the same file, but Systemd handles all the inter-relations between the containers just fine.

    Alternatively Podman also supports kubernetes configuration files, which is probably closer to what you have in mind, but I never tried that myself as the above is much simpler and better integrated with existing Systemd service files.

      Quadlet

      Requires podman 4.4 though

        No, from that version on, it is integrated in Podman, but it was available for earlier versions as a 3rd party extension as well.

        But if you are not yet on Podman 4.4 or later you should really upgrade soon, that version is quite old already.

    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.

  doesn’t systemd come with it’s own container thingy?

    You're probably thinking about systemd-nspawn. Technically yes they're containers, but not the same flavour of them. It's more like LXC than Docker: it runs init and starts a full distro, like a VM but as a container.

    Nope, but it integrates very well with Podman.
