Additional information

#17851 and #17580 have also reported this & been closed, but this is still happening.

This is quite painful, because always containers are always restarted. Many devs in my org will have multiple copies of, for example, a postgres database container. We expect to be able to stop most of them, but have one started, and have that one and only that one resume when podman machine starts up after reboot.

But currently, with podman-restart, all always containers will start, and the multiple postgres containers will all try to grab the same 5432 port.

There were some asks in #10539 about how to implement unless-stopped, but no answers were found there. It seems like we need to store more state than we have available (or than I know how to access) to properly implement this capability: we have to know what containers were running, which were stopped, as podman shuts down/system reboots.

[rhatdan]

I think the problem here is differentiating between whether the container was actually stopped.

@vrothberg Do you know about this?

[vrothberg]

Needs investigation. The podman-restart.service only stops containers with restart=always on shutdown but there may still be something else at play.

[vrothberg]

Ah, yes. The restart service only starts containers with --restart=always.

[rhatdan]

Does Docker differentiate ones that we shutdown via Human versus shutdown because the system was rebooting. We might need to somehow figure this out. I would figure restart "unless-stopped" containers should start on reboot, if they we shut down via reboot, as opposed to someone doing a podman stop. (Of course I am not sure Podman knows the difference since systemd is trigging podman stops.

[jennydaman]

For those who are looking for a fix, run

systemctl --user edit podman-restart.service

And add

[Service]
ExecStart=
ExecStart=/usr/bin/podman $LOGGING start --all --filter restart-policy=always --filter restart-policy=unless-stopped
ExecStop=
ExecStop=/bin/sh -c '/usr/bin/podman $LOGGING stop $(/usr/bin/podman container ls --filter restart-policy=always --filter restart-policy=unless-stopped -q)'

Save, then run

systemctl --user enable podman-restart.service

I regret to inform that this glaring error has yet to be rectified.
