Radarr

Radarr is a movie collection manager for Usenet and BitTorrent users. It can monitor multiple RSS feeds for new movies and will interface with clients and indexers to grab, sort, and rename them. It can also be configured to automatically upgrade the quality of existing files in the library when a better quality format becomes available. Note that only one type of a given movie is supported. If you want both an 4k version and 1080p version of a given movie you will need multiple instances.

Setup

Radarr is best installed as a service on NixOS in your configuration.nix.

A basic install can be done using the following options:

services.radarr = {
  enable = true;
  openFirewall = true;
};

The openFirewall option is used to open port 8989 on the host firewall.

Further configuration

Radarr can be further configured using NixOS options.

services.radarr = {
  ...
  user = "user";
  group = "group";
  dataDir = "path/to/directory"
};

Both the user and group options are used to specify which user and group is used to run Radarr. The dataDir option specifies the directory where Radarr stores its data files, and can be set to a custom location. When setting the dataDir option, be careful of permissions as a specified user still needs the correct read/write permissions in this directory.
