Hi Goby, while its technically possible: yes, you can docker exec into the container and edit /jellyfin/jellyfin-web/… its practically painful: every time the container is rebuilt (e.g. Jellyfin update, Synology restart with a fresh pull, or if you ever nuke/redeploy), all those edits are gone.
Docker images are meant to be immutable. You’re not supposed to hack the inside because the next update overwrites it. But that said, its just 2 files and 1 injection line.
For persistent customization you ~could~ blind-mount your own web override by putting the customized UI/ folder (with spotlight.html + spotlight.css) somewhere on the NAS (outside the container).
Then you tell Docker:
But you still have to edit the injection line into the chunk file and I had to gpt even that command so I couldn't help much further, sorry
If you are able to get it going let us know!
