Updated and now can't add library/files

[private_wombat]

I decided to update the container to the newest version last night. After the update, JF lost my old library

I would just like to point out that you did not persist any of your Jellyfin data in the Docker setup you provided. Those environment variables listed (i.e., JELLYFIN_*) represent folders. If you do not map them, they are destroyed when you remove the container -- which happens when you update the container. I think you need the DATA_DIR and CONFIG_DIR, but the DATA_DIR is top-level, so the rest should follow. That needs to be mapped the way you mapped your media in the volumes section.

Code:

  - /path/to/store/jf/data:/config

I would start fresh (which you're doing already) and map this volume, see what happens.

I'm sure I messed that up, I'm a total noob and I have no idea what I'm doing. So that is something I should have said at the outset. I am honestly not even sure why this is coming up now as the last time I installed I didn't do anything with mapping DATA_DIR and CONFIG_DIR as it worked right out of the gate with no tweaking/config changes. 

When you mention mapping DATA_DIR and CONFIG_DIR with the code snippet you pasted, where do I put that? I'm sorry to be so stupid about this, I'm genuinely lost as to why this install/update is so different than last time. Really appreciate your help.
