From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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.

Podman is fully open source, there is podman desktop

I just wish podman-compose wasn't so scuffed. I submitted a PR about some garbage months ago and it just seems dead.

[–] letbelight@lemmy.ml 1 points 1 year ago

You need to mention muayyad-alsadi, because the only one who maintain it now seems only him. Just keep mentioning, and he will review the PR.

You're supposed to use podman kube play instead of that

[–] Molecular0079@lemmy.world 1 points 1 year ago (1 children)

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

[–] Static_Rocket@lemmy.world 1 points 1 year ago (1 children)

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?

[–] Molecular0079@lemmy.world 1 points 1 year ago (1 children)

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.

[–] Static_Rocket@lemmy.world 1 points 1 year ago

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.
