Configuration

Configuration

You can set everything up through the web UI in Settings, but you can also pass environment variables if you prefer to set things at the Docker level.

Required

Variable	What it is
PLEX_URL	Your Plex server URL, e.g. http://192.168.1.100:32400
PLEX_TOKEN	Your Plex token (how to find it)

Sonarr & Radarr

Not technically required, but you'll want at least one of these — it's how Prunerr actually removes content.

Variable	What it is
SONARR_URL	Sonarr URL
SONARR_API_KEY	Sonarr API key (Settings > General > Security)
RADARR_URL	Radarr URL
RADARR_API_KEY	Radarr API key (Settings > General > Security)

Watch History

You need one of these for watch-based rules to work. Without it, Prunerr won't know what's been watched.

Variable	What it is
TAUTULLI_URL	Tautulli URL
TAUTULLI_API_KEY	Tautulli API key (Settings > Web Interface)

Tracearr is an alternative if you don't run Tautulli. Configure it through the Settings UI.

Optional

Variable	What it is
OVERSEERR_URL	Overseerr/Seerr URL
OVERSEERR_API_KEY	Overseerr API key
DISCORD_WEBHOOK_URL	Discord webhook for notifications
PRUNERR_API_KEY	Override the auto-generated API key
LOG_LEVEL	error, warn, info, or debug (default: info)
PUID / PGID	User/group ID for file permissions (default: 99/100)

Service Health

Once everything's connected, the dashboard shows a Service Status panel with connection status and response times for each service. If something's red, check the URL and API key.
