  1. Overseerr — Users submit requests for movies or TV shows
  2. Sonarr / Radarr — Receives the request and searches for releases via Prowlarr
  3. Prowlarr — Queries configured indexers and returns results to Sonarr/Radarr
  4. Flaresolverr — Assists Prowlarr with indexer sites behind Cloudflare
  5. qBittorrent — Downloads the selected release to /media/Downloads
  6. Sonarr / Radarr — Detects the completed download, moves/renames the file to the library
  7. Plex — Detects the new file and makes it available for streaming

Volume mounts

Container Container Path Host Path Purpose
Sonarr /config /opt/mediaserver/sonarr Config and database
Sonarr /media/TV Shows /stash/rodneystash/TV Shows TV library (ZFS)
Sonarr /media/Downloads /stash/rodneystash/Downloads Download import path
Radarr /config /opt/mediaserver/radarr Config and database
Radarr /media/Movies /stash/rodneystash/Movies Movie library (ZFS)
Radarr /media/Downloads /stash/rodneystash/Downloads Download import path
qBittorrent /config /opt/mediaserver/qbittorrent/config Config
qBittorrent /media/Downloads /stash/rodneystash/Downloads Download destination
Prowlarr /config /opt/mediaserver/prowlarr Config
Overseerr /app/config /opt/mediaserver/overseerr/config Config

Permissions

All Linuxserver.io containers run with PUID=0 and PGID=0 (root). Files created on the ZFS pool are owned by root:root with 755/644 permissions. Plex (uid 999) has read access via world-readable permissions.

Adding a new service

  1. Add the service to the Portainer stack compose file
  2. Map config to /opt/mediaserver/<service>/config:/config
  3. If it needs media access, mount paths from /stash/rodneystash/ at the paths the app expects
  4. Redeploy the stack via Portainer
