I vaguely understand what docker is. I’ve tried to set it up on my Mac and had no luck getting it going. My understanding is that if you want to move your jellyfin install to another machine, it’s easy to just grab the whole container rather than hunting down jellyfin’s settings spread throughout the disk. I’ve moved a Plex installation and it’s not fun. It’s not hard but it’s not fun. So yes, it would be beneficial to be able to just move a container from machine to machine if need be.

I’m not new, but I shouldn’t consider myself any more advanced than a new/beginner level user. I remember liking Red Hat back when that was a home user distro. I didn’t much like Fedora. I have used Mint and I like it well enough. I also like Ubuntu. Heard good things about one called Cachy.
