This may not be the answer you are looking for, but one method would be to use WSL on windows to run a Linux distro with Docker installed and just migrate everything over, basically 1-to-1. Then set WSL to auto start when you boot up windows. If you install Docker Desktop on Windows, it will also pick up that you’re using Docket via WSL and allow you to manage shit from the client. I don’t do that though, I’m a masochist old-school.

Sadly it’s unavailable while it is being re-worked, but I am really hoping it turns out to be good. It’s not all too hard to find a cheap or free used/refurb PC that’s good enough to play video on a TV
