Nixarr

This is a Nixos module that aims to make the installation and management of a home media server as easy, and pain free, as possible.

If you have problems or feedback, feel free to join the discord.

Note that this is still in a somewhat alpha state, beware!

• Bugs are around
• Options are still subject to change
• Some options are mostly untested

The general format won't change however. If you do still use it, any feedback would be greatly appreciated.

Features

• Run services through a VPN: You can run any service that this module supports through a VPN, fx nixarr.transmission.vpn.enable = true;
• Automatic Directories, Users and Permissions: The module automatically creates directories and users for your media library. It also sets sane permissions.
• State Management: All services support state management and all state that they manage is located by default in /data/.state/nixarr/*
• Optional Dynamic DNS support: If you use Njalla and don't have a static IP, you can use the nixarr.ddns.njalla.enable option to dynamically update a DNS record that points to the dynamic public IP of your server or your public VPN IP.
• Optional Automatic Port Forwarding: This module has a UPNP support that lets services request ports from your router automatically, if you enable it.

To run services through a VPN, you must provide a wg-quick config file, that is provided by most VPN providers:

  nixarr.vpn = {
    enable = true;
    # WARNING: This file must _not_ be in the config git directory
    # You can usually get this wireguard file from your VPN provider
    wgConf = "/data/.secret/wg.conf";
  }

It is possible, but not recommended, to run the "*Arrs" behind a VPN, because it can cause rate limiting issues.

Importing this module

To use this module, add it to your flake inputs in your nix flake file, like shown in this example flake:

  {
    description = "Your nix flake";

    inputs = {
      nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
      nixarr.url = "github:rasmus-kirk/nixarr";
    };

    outputs = { 
      nixpkgs,
      nixarr,
      ...
    }@inputs: {
      nixosConfigurations = {
        servarr = nixpkgs.lib.nixosSystem {
          system = "x86_64-linux";

          modules = [
            ./nixos/servarr/configuration.nix
            nixarr.nixosModules.default
          ];

          specialArgs = { inherit inputs; };
        };
      };
    };
  }

VPN Providers

Your VPN-provider should at the very least support wg-quick configurations, this module does not, and will not, support any other setup. Most VPN-providers should support this ATM.

Secondly, it's recommended that the VPN you're using has support for static port forwarding as this module has no builtin support for dynamic port forwarding. I suggest AirVpn, since they support static port forwarding, support wg-quick configurations and accept Monero, but you can use whatever you want.

Domain Registrars

If you need a domain registrar I suggest Njalla, they are privacy-oriented, support DDNS and accept Monero. Note that you don't technically "own" the domain for privacy reasons, they "lease" it to you. However, this also means that you don't have to give any personal data.

Thanks

A big thanks to Maroka-chan for the heavy lifting on the VPN-submodule, that was integral to making this project possible.

I would also like to thank Lasse for helping out with the website.
