Documentation: How to specify nixopsConfiguration.default? about nixops

[ldicarlo]

Hi, can you provide your flake.nix if any ?

[akavel]

@tartavull Sooo, based on

nixops/nix/eval-machine-info.nix

Line 20 in fc9b55c

flakeExpr = (builtins.getFlake flakeUri).outputs.nixopsConfigurations.default;

and some other lines in that file, as well as some rough understanding of flakes in general, I seem to believe a minimal flake.nix for nixopsUnstable would look like below:

{
  description = "NixOps config of my servers";

  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/release-22.11";
  };

  outputs = { self, ... }@inputs: {
    nixopsConfigurations.default = {
      inherit (inputs) nixpkgs;

      network.description = "my servers";
      network.storage.legacy = {};
      #network.storage.memory = {};  # what's the difference with above?
      #network.enableRollback = true;  # uncomment if you like/know what this even does

      ### Machines ###

      #my-machine-1 = { pkgs, ... }: {
      #  deployment.targetHost = "1.2.3.4";
      #  services.nginx.enable = true;
      #};
    };
  };
}
