I am setting up my first jellyfin server via docker, and I am offered the option to either use TMDB or OMDB. I have jellyfin on a LAN-connected device w/o VPN connection, and I am concerned queries to those DBs with file names of torrented files can get tracked and reported to my ISP. Could that be the case? And if so what to do about it? Are there more privacy-preserving metadata services than others?
Yes as long as you expose the ports for the jellyfin web GUI within the gluetun container as the other commenter mentioned.
In each container, you want to change your network to the gluetun container:
network_mode: "container:gluetun"
The first time you docker-compose up, you might get an error that the gluetun container doesn’t exist. Just run it twice and you’ll be good.
