Yeah faced that issue a couple of weeks ago as well after updating Podman. It didn’t allow me to set container individual UID/GID mappings or UserNS when running in a pod, so I just took them out of the pod as I couldn’t be bothered and run them as separate containers in the same network. Works just as good.

You just have to make sure to move the PublishPort block from the pod quadlet to the gluetun container (for all the containers which route their traffic through gluetun, i.e. which have ‘Network=container: gluetun’ set). This should solve the problem and still allows you to use UserNS or UID/GID mappings on the containers. No disadvantages so far, you just lose the convenience of stopping/starting all the containers at once through the pod. But I’d rather take this ‘inconvenience’ than troubleshooting for days how to make it work with a pod again.

Nice setup! Is that a Minisforum below the optiplex?

Haha I read your comment the wrong way around the first time thinking you got a Minisforum MS-01 for like €460. That would have been a great deal 😄

Because searching for what a new MS-01 with i5 and 32gb RAM and 1TB SSD cost is more towards €700. Haven’t found a lot of offerings for a used one in my region and buying new currently I think I would have to pay too much.

Ah nice, another vintage story aficionado 👌 Have my server running on my mini pc in a LXC since a couple of weeks, sadly haven’t found a lot of time exploring v1.21 since becoming a dad last year 😄

But yeah was looking for a bit beefier server hardware to maybe run some more game servers like Valheim or Satisfactory besides my other selfhosting services.

Just try the simple image, see https://github.com/alam00000/bentopdf?tab=readme-ov-file#-simple-mode-for-internal-use :)

That’s where UserNS=keep-id:uid=1000,gid=1000 comes 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/24934

Well 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.

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:

I run my podman containers in a VM running Alma Linux. 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, did the same for some services I run at home. Now in the process of migrating my stuff on my vps from docker compose to quadlets. It’s a bit more involved but worth the QoL stuff quadlets bring with them, like automatic updates and systemd integration. I’m curious, which is your Linux distro of choice to run your podman quadlets on?
