Just make sure to mount your volumes with the :z or :Z flags. I have disabled SELinux on servers in the past, but never when I’ve just used podman containers, since “it just works” with SELinux. Literally never had any problems with containers and SELinux.
I’m currently running Jellyfin on a VM in Proxmox and have been for a long time, it works great. My storage solution isn’t glorious, but it is simple. I just have a Debian LXC container in proxmox that bind mounts a large disk and exposes that through an NFS share. Then I’ve installed jellyfin with Podman/Docker on a VM that has that NFS share mounted.
Also, a lot of people have already said this, but Podman/Docker only looks intimidating before you use it. It’s A LOT easier to get applications running then using the “traditional way”. The only thing that could potentially increase complexity for you is to expose a GPU to the docker container. But since you said you don’t have a dedicated GPU I’d strongly recommend using a docker container for the job. Once you’ve used it, you’ll never look back.
I used to manage the file hierarchy myself, but I haven’t done that for years at this point. Same goes for tagging files and such. I just download everything to a root folder called “music” and let lidarr handle everything from there.
Lidarrs default file structure is something like {Artist}/{Album}{Year}/{Track} . This can of course be changed. Then I let lidarr just tag everything for me automatically, embedding album art and such.
It’s a great setup overall, but I don’t know where Lidarr indexes it’s music library from, because some artists and albums might be missing sometimes. That’s really the only pain point.
I haven’t used Jellyfin with docker before, just with podman and as a pod in k3s. Both work great and are easy to maintain. If you’re more familiar with podman then docker, then I’d recommend using podman.
