nixosConfigurations

The nixosConfigurations attribute lets you set outputs for NixOS systems and home-manager users.

It should be set to an attribute set. Each value should be a set of nixpkgs.lib.nixosSystem args, the result of calling nixpkgs.lib.nixosSystem, or a function that takes moduleArgs and returns one of the prior.

When using a set of nixpkgs.lib.nixosSystem args, NixOS modules will have access to a flake module arg equivalent to moduleArgs plus inputs' and outputs'. Conflake's pkgs attributes, withOverlays, and packages will also be available in the NixOS instance's pkgs, and Conflake's nixpkgs.config will apply to it as well.

Usage

For example:

{
  inputs.conflake.url = "github:ratson/conflake";
  outputs = { conflake, ... }:
    conflake ./. ({ lib, config, ... }: {
      nixosConfigurations.test-system = {
        system = "x86_64-linux";
        modules = [{ system.stateVersion = "24.05"; }];
      };
    });
}
