google_image_nixos

This terraform module creates a new image in the Google Cloud project using a public tarballs of a NixOS release. Those tarballs are released by the NixOS project.

Since image names are unique, only one instance per version of the module is supported per Google Cloud project.

Example

module "nixos_image_1809" {
  source = "github.com/tweag/terraform-nixos/google_image_nixos"
  nixos_version = "18.09"
}

resource "google_compute_instance" "example" {
  name         = "example"
  machine_type = "n1-standard-1"
  zone         = "us-central1-a"

  boot_disk {
    initialize_params {
      image = module.nixos_image_1809.self_link
    }
  }

  network_interface {
    network       = "default"
  }
}

Default configuration.nix

A new configuration.nix can be passed trough the userdata. Here is the default configuration to expand upon:

{ modulesPath, ... }:
{
  imports = [
    "${toString modulesPath}/virtualisation/google-compute-image.nix"
  ];
}
