I just setup the ARR stack and you can use a docker compose file to manage all the services. Then you need to create individual account for the services but that is straight forward.

You’ll need to do some config on the actual services as well. Mostly in regards to telling it how you want to add things to your wanted list, how it should search for files, how you want it to download files, how it should handle downloaded files to be compatible with your media server, etc… Docker-compose can do a lot, but the *arr services are too granular to define everything directly in the compose file. You’ll need to actually configure the services after they are booted up via docker.

My stack includes the following:
Prowlarr for tracker management. This defines the various search methods, and makes them available for the rest of the stack.
Seerr for media requests. This manages what shows/movies are on the stack’s search list.
Sonarr for TV shows. Seerr tells it what to search for. It takes the relevant trackers from Prowlarr, and uses them to search for wanted media. It grabs media from the search based on quality profiles. For instance, my profiles are set to exclude 3D media, because none of my screens can display 3D. This is synced with my torrent client for automated downloads. When a download is completed, it automatically creates a hardlink in the relevant media folder for my media server to find. It uses the specific naming scheme for the media program, so the program can automatically detect info about the files.
Radarr for movies. Same basic concept as Sonarr.
Cleanuparr for download management (and some basic malware protection). Tracks downloads’ ratios, and automatically removes them from my torrent list when the ratio/time threshold is met. It also tracks “slow” torrents and will automatically retry them if a torrent is stalled/slow for too long. Also does some basic “movie.mp4.exe” torrent checking, to automatically block malicious downloads that get grabbed by the rest of the stack.
Bazarr for subtitle downloads. Automatically analyzes my media, and finds matching subtitle files for my media server to use.

Each of these will require specific config steps. For instance, Prowlarr will need to know which torrent/usenet trackers you want to use. Sonarr will need to know how to interface with your download client, which files to grab based on quality profiles, and how to rename files during import.
