I'm running podman and podman-compose with no problem. And I'm happy. At first I was confused by the uid and gid mapping the containers have, but you'll get used to it.
This are some notes I took, please don't take all of it for the right choice.
Podman-Stuff
https://github.com/containers/podman/blob/main/docs/tutorials/rootless_tutorial.md
storage.conf
To use the fuse-overlay driver, the storage must be configured:
.config/containers/storage.conf
[storage]
driver = "overlay"
runroot = "/run/user/1000"
graphroot = "/home/<user>/.local/share/containers/storage"
[storage.options]
mount_program = "/usr/bin/fuse-overlayfs"
Lingering (running services without login / after logout)
https://github.com/containers/podman/issues/12001
https://unix.stackexchange.com/questions/462845/how-to-apply-lingering-immedeately#462867
sudo loginctl enable-linger <user>
Yes all users that have containers running, that should keep running need lingering.
The Services do not restart themself. I have cronjob that executes
podman start --all
at reboot for my "podman user".
