So let’s say I theoretically wanted to move a docker container to another device or maybe if I were re-installing an OS or moving to another distro, could I in theory drag my local docker container to an external and throw my device in a lake and pull that container off into the new device? If so … what then, I link the startups, or is there a “docker config” where they are all able to be linked and I can tell it which ones to launch on OS launch, User launch, delay or what not?

For ease of moving containers between hosts I would use a docker-compose.yaml to set how you want storage shared, what ports to present to the host, what environment variables your application wants. Using Wordpress as an example this would be your starting point
github.com/docker/awesome-compose/…/compose.yaml
all the settings for the database is listed under the db heading. You would have your actual database files stored in /home/user/Wordpress/db_data and you would link /home/user/Wordpress/db_data to /var/lib/MySQL inside the container with the line
As the compose file will also be in home/user/Wordpress/ you can drop the common path.
That way if you wanted to change hosts just copy the /home/user/Wordpress folder to the new server and run docker compose up -d and boom, your server is up. No need to faf about.
Containers by design are suppose to be temporary and the runtime data is recreated each time the container is launched. The persistent data is all you should care for.

“Containers by design are suppose to be temporary and the runtime data is recreated each time the container is launched. The persistent data is all you should care for.”
So that’s really why they should be good for Jellyfin/File servers, as the data isn’t needing to be stored in container, just the run files. I suppose the config files as well.
When I reverse proxy to my network using wireguard (set up on the jellyfin server, I also think I have a rustdesk server on there) on the other hand, is it worth using a container, or is that just the same either way?
I have shoved way to many things on an old laptop, but I never have to touch it really, and the latest update mint put out actually cured any issues I had. I used to have to reboot once a week or so to get everything back online when it came to my Pihole and shit. Since the latest update I ran in September 4th, I haven’t touched it for anything. Screen just stays closed in a corner of my desk with other shit stacked on top
