Podman, rootless containers work well, and there is no central process running everything. I like that starting containers on boot is integrated with systemd.
How do you automatically start podman containers? I currently just manually add systemd entries but that’s a lot more cumbersome than Docker which doesn’t require you to do anything at all.
I use Quadlet, which is now merged in podman. The only issue I had with it is running system systemd services as other (rootless) users, I can’t get it to create cid files that the users can access. In those cases only, I have to modify the generated services files, which defeats the purpose.
Since I use Docker Compose with Podman, I just make a single systemd service to run Docker Compose on boot, thereby starting all my containers at once.
I have one Compose file per stack, which is an application and all of its containers, databases, etc. Pretty much the same way I organized things with just Docker.
Podman supports docker compose just fine. You have to run it as a service, so that it can expose a socket like docker does, but it supports doing exactly that
Check my comment history for an example of a simple bind mount compose.yaml I use for developing a small Python project. It’s exactly the same as Docker Compose (since Podman Compose follows the Compose spec) but if you’re just getting started, it might be a good skeleton to build on.

That’s an interesting way to do it. Do you have everything in 1 compose file?

i would like to try… but as far as i know, there is no “docker compose up -d”

Apparently it does! podman-compose
cool, thank you!
