People resoundingly suggested using containers. So I’ve been reading up. I know some things about containers and docker and what not. But there are a few decision points in the jellyfin container install instructions that I don’t know the “why”.

Data: They mount the media from disk, which is good cause it’s on a NAS. But for the cache and config they use docker volumes. Why would I want a docker volume for the config? Wouldn’t I want to be able to see it from outside the container easier? What am I gaining by having docker manage the volume?

Cache: I saw a very old post where someone mentioned telling docker to use ram for the cache. That “seems” in theory like a good idea for speed. I do have 16gb on the minipc that I am running this all on. But I don’t see any recent mentions of it. Any pros/cons?

The user. I know from work experience that generally you don’t want things running as root in the container. But… do you want a dedicated user for each service (jellyfin, arr*)? Or one for all services, but not your personal user? Or just use your personal user?

DLNA. I had to look that up. But I don’t know how it is relevant. The whole point seems to be that jellyfin would be the interface. And DLNA seems like it would allow certified devices to discover media files?
