Migrating from docker to podman, encountering some issues - eviltoast

I’ve been messing around with podman in Arch and porting my self-hosted services over to it. However, it’s been finicky and I am wondering if anybody here could help me out with a few things.

  1. Some of my containers aren’t getting properly started up by podman-restart.service on system reboot. I realized they were the ones that depended on my slow external BTRFS drive. Currently its mounted with x-systemd.automount,x-systemd.device-timeout=5 so that it doesn’t hang up the boot if I disconnect it, but it seems like Podman doesn’t like this. If I remove the systemd options the containers properly boot up automatically, but I risk boot hangs if the drive ever gets disconnected from my system. I have already tried x-systemd.before=podman-restart.service and x-systemd.required-by=podman-restart.service, and even tried increasing the device-timeout to no avail.

When it attempts to start the container, I see this in journalctl:

  1. When I shutdown my system, it has to wait for 90 seconds for libcrun and libpod-conmon-.scope to timeout. Any idea what’s causing this? This delay gets pretty annoying especially on an Arch system since I am constantly restarting due to updates.

All the containers are started using docker-compose with podman-docker if that’s relevant.

Any help appreciated!

EDIT: So it seems like podman really doesn’t like systemd automount. Switching to nofail, x-systemd.before=podman-restart.service seems like a decent workaround if anyone’s interested.

    What happens if you use regular docker-compose but with podman-docker? I’ve gotten better results with that.

      It just bothers me that I have to use a tool outside of the ecosystem for that. Doesn’t it also behave differently though? Like doesn’t it assume everything is root when you use the socket required for docker-compose?

        Yes, I think it does, but thats how docker-compose works with docker anyways so it’s a closer experience. I think if you’re using docker-compose files you sorta want that docker-like experience no?

        I get where you’re coming from though. It would be nice to run docker-compose files completely rootless with podman-compose.

          Eh, I don’t mind learning a new config if the tool requires it. I just want to define run commands in yaml and have it auto generate pods and startup scripts.
