Metadata Provider Settings

These settings configure the integrations with external metadata providers like The Movie Database (TMDB) and The TVDB.

TMDB (The Movie Database)

TMDB is the primary metadata provider for MediaManager. It provides detailed information about movies and TV shows. Get an API key from The Movie Database to use this provider. You can create an account and generate a free API key in your account settings.

Other software like Jellyfin use TMDB as well, so there won't be any metadata discrepancies.

Variable	Default	Example
TMDB_API_KEY	None	TMDB_API_KEY=your_tmdb_api_key_here

TVDB (The TVDB)

The TVDB might provide false metadata, also it doesn't support some features of MediaManager like to show overviews, therfore TMDB is the preferred metadata provider.

Get an API key from The TVDB to use this provider. You can create an account and generate a free API key in your account settings.

Variable	Default	Example
TVDB_API_KEY	None	TVDB_API_KEY=your_tvdb_api_key_here

Directory Settings

Normally you don't need to change these, as the default mountpoints are usually sufficient. In your `docker-compose.yml`, you can just mount `/any/directory` to `/data/torrents`.

Variable	Description	Default
IMAGE_DIRECTORY	media images (posters, backdrops) will be stored.	/data/images
TV_DIRECTORY	location of TV show files	/data/tv
MOVIE_DIRECTORY	location of movie files	/data/movies
TORRENT_DIRECTORY	location of torrent files and downloads	/data/torrents

Build Arguments (Dockerfile)

Argument	Description	Example (in build command)
VERSION	Labels the Docker image with a version. Passed during build (e.g., by GitHub Actions). Frontend uses this as PUBLIC_VERSION.	docker build --build-arg VERSION=1.2.3 .
