@Tippon That is a big part of the point behind containers, you don't have any long term state inside them. Migration is just a case of copying the configuration over along with the contents of any persistent volumes.
It's worth looking into Podman instead of Docker, the daemon-less architecture makes it more lightweight and secure as it's easier to have rootless containers. Management can also be easer as being a Red Hat project it integrates well into Systemd.
With your existing server on Xubuntu you may as well stick with Ubuntu Server or Debian for the familiarity.
Podman also has tooling for deploying containers as systems services or as k8s deploymentments.
I have no idea what that means! (yet :D).
Time for some research :)
Brilliant :)
I've just been reading some of the other replies, and, yeah, it looks like containers are the way to go. I've got my data on separate drives, so that's easy enough to deal with, it's just the container side of things that's been confusing me.
I'll have a look at Podman, thanks :)
Like you say, I'm probably better off with a Debian fork, especially as I'm using Mint on my laptop, and should be on my PC if I can find alternatives to a few programs :)
I've been working with podman for a few weeks, and it's functional but a bit harder. If you're a noobie I would recommend you stick to docker. If you're a FOSS enthusiast and up for a little more challenge podman is pretty cool.
