My Jellyfin config has some YAML like this.

# Sometimes work  
devices:  
- /dev/dri/renderD128:/dev/dri/renderD128  
- /dev/dri/card0:/dev/dri/card0

Occasionally when I reboot my server, I end up with no card0 and instead I have /dev/dri/card1. This breaks my Jellyfin server…

I noticed there is also dri/by-path, which I’m guessing is a more stable path than a card index… however, doing this doesn’t work for me.

# No work  
devices:  
- /dev/dri/by-path/pci-0000:00:02.0-render:/dev/dri/renderD128  
- /dev/dri/by-path/pci-0000:00:02.0-card:/dev/dri/card0

I tried with and without quotes and the result is the same. Error to start. I’m guessing Docker is failing to correctly parse the string because of the colons in pci-0000:00:02.0-card…

How’s everyone else handling this problem? I’ve been updating my compose.yaml every time the index switches, card0 to card1 to card0… but this is getting annoying now. (This is a worse problem now that I’m running Fedora IoT!)

Any thoughts?

        I had the same issue a while ago. :) I think the docs tell you to do it the way you had it, which is why it causes confusion.

      This is also good because if you have a newer cpu it has integrated graphics built in, and you have a dedicated gpu card, will give you two devices here, which this will auto mount both.
