Plex Media Server in Docker

Running Plex with hardware transcoding via Intel Quick Sync on my home server.

Docker Compose

plex:
  image: lscr.io/linuxserver/plex:latest
  container_name: plex
  network_mode: host
  environment:
    PUID: 1000
    PGID: 1000
    TZ: Europe/Paris
    VERSION: docker
  devices:
    - /dev/dri:/dev/dri
  volumes:
    - /app-config/plex:/config
    - /data:/data
  restart: unless-stopped

Key Decisions

network_mode: host -- required for DLNA discovery and local streaming to work without hassle. Plex uses a lot of random ports for local device discovery.
/dev/dri:/dev/dri -- passes through the Intel integrated GPU for hardware transcoding. Without this, Plex falls back to software transcoding which maxes out the i3 quickly.
Single /data mount -- Plex sees /data/media/movies and /data/media/tv. This is the same mount Radarr/Sonarr use, so hardlinks work (no duplicate disk usage).

Media Library Structure

/data/media/
  movies/
  tv/

Plex libraries are pointed at /data/media/movies and /data/media/tv.

Monitoring

Tautulli runs alongside Plex for viewing stats and history -- see the Tautulli TIL.
