Do you guys have any success with setting up an arr stack with rootless Podman Quadlets? I really like the idea of Quadlets, but I can’t make it work.
Any guide and/or experience sharing would be greatly appreciated.
I have set up a Rocky Linux 10 with Podman 5.4.2 but after downloading the containers the quadlets were crashing.
Shall I continue digging this rabbit hole or shall I switch back to Docker Compose?
Nice, did the move from docker to podman a couple of months ago myself. Now running the arr stack, nextcloud, immich and some other services as quadlets. File permission due to podmans rootless nature usually was the culprit if something was not working properly.
I can share my quadlet systemd files I use for the arr stack. I deployed it as a pod:

Works pretty great so far.
Had the same issue when debugging systemctl errors, journalctl not being very helpful. At one point I just ran
podman logs -f <container>in another terminal in a while loop just to catch the logs of the application. Not the most sophisticated approach, but it works 😄Nice, thanks for sharing. How did you solve the file permission issue?
Also I see you put all your services as a single pod quadlet what I am trying to achieve is to have every service as a separate systemd unit file, that I can control separately. In this case you also have a complication with the network setup.
That’s where
UserNS=keep-id:uid=1000,gid=1000comes into play. It “maps” the containers’ user to your local user on the host to some extent, there is a deeper explanation of what exactly it does in this GitHub issue: https://github.com/containers/podman/issues/24934Well the pod only links the container together, it’s not one systemd file. Every container has its own file, so does the pod and the network (separated by ‘—’ in my code block above). You still can start and stop each container as a service separately or just the whole pod with all containers linked to it. Pods have the advantage that the containers in them can talk to each other more easily.
The network I just created to separate my services from each other. Thinking of it, this was the old setup, as I started using gluetun and run it as a privileged container, it’s using the host network anyway. I edited my post above and removed the network unit file.
