Honestly if you have absolutely no idea then replicating my exact setup might be a bit steep.

Before i made the download script (which i can share if you ping me next week when i am back home) i already had a 24/7 Ubuntu server with docker running multiple containers like a small Minecraft server.

You could replicate much of what i did on windows and a not always online machine but it may take some extra steps to get working.

I also got much help from chatgpt-(4) the last year for all kinds of linux/docker/scripting questions, my total linux experience is less then 3 years.

I recommended to start of trying to host invidious, which on itself could already be a full experience without requiring local storage or scripts.

For any questions regarding docker i continuing to highly recommend chatgpt but remember its quality is entirely dependent on your ability to recognize “makes sense” versus “dangerously derailed bullshit”

If you have this working then getting jellyfin to work in docker will be a breeze. Only step remaining would be using a script like mine to download the videos and save them in the library folder. And as mentioned once i am back home next week i’ll be happy to share it and explain further.
