21-nixos-configurations

This example shows a small nixosConfigurations output.

It includes:

  • a local module in module.nix,
  • one full system configuration exposed as nixosConfigurations.demo, and
  • a check that reads values from the evaluated system configuration.

Useful commands:

nix flake show
nix eval .#nixosConfigurations.demo.config.networking.hostName --raw
nix flake check
