Problem with upgrade and configuration

[v0rt]

Hi, 

Version: Actualy 10.10.7
Installation: Docker and Portainer for deploy on Ubuntu 25.04
Description:
I'm having some issues with my Jellyfin instance that I can't seem to resolve. When the Docker image is updated (sometimes):
- I lose the media libraries, but the files are still accessible from the interface; the update, however, when there's new media, no longer works.
- I lose the extensions, extension repositories, and configuration.
- Sometimes, after the update, it tells me that the server doesn't exist, and I have to reconnect.

I've already done multiple reinstallations from scratch, but I find it's starting to get overwhelming and quite annoying. I've tried the recommended mount points, I've tried hard-setting more points, I've tried numerous solutions, and I can't seem to resolve this issue. Do you have any leads?

Thank you in advance for your help.

Can you post your compose file?

For one thing you are never suppose to use the same volume for both the /config and /cache internal directories.

I believe the official recommendation is to use bind mounts for the config/cache directories. The way you're doing it now is letting Docker obfuscate that away and it sounds like there's a problem regarding the containers ability to properly read the config files (most likely since you're using a single volume for both /config and /cache) since you stated your instance looses that information upon upgrading.

If you are hell-bent on using docker volumes instead of bind mounts, then use a different volume for each path:

Code:

    volumes:
      - config:/config
      - cache:/cache
volumes:
  config:
  cache:

My recommendation is to read the docs completely, then start over from scratch.

Okay, I can try that and see if it works better. All my containers work in bulk, only the Jellyfin one is giving me problems. I'll try the recommended method, even though I think I've already tried it.

I'll give it a try and let you know.

Hi!

It took me a while to re-configure, but I feel like it's working much better! I already feel smoother when browsing, reading, and everything else, and my plugins are finally working properly, and the media library isn't getting deleted.

So, for me, everything's fine !

Thanks
