i didn't have much trouble

    services:
      jellyfin:
        build:
          dockerfile: jellyfin.Dockerfile
        container_name: jellyfin
        group_add:
          - 44
          - 993
        environment:
          - TZ=<redacted>
          - JELLYFIN_PublishedServerUrl=<redacted>
          - DOMAIN_NAME=<redacted>
        ports:
          - 8096:8096
          - 8920:8920
          - "7359:7359/udp"
        volumes:
          - ./config:/config
          - ./cache:/cache
          - ./config/index.html:/jellyfin/jellyfin-web/index.html
          - type: bind
            source: /mnt/storage/Video
            target: /media
        restart: always
        devices:
          - /dev/dri:/dev/dri

the device and group_add were for integrated graphics passthrough for transcoding (very highly recommend if you're containerized)

i also recommend seerr to pair with jellyfin: https://seerr.dev/

my wife logs into the seerr ui with her jellyfin account, makes requests, they get grabbed by sonarr/radarr, which in turn place them in the correct library, and they're identified & labeled correctly on import
