Hetzner Cloud installation

⚠️ Only works with VMs that have more than 2GB of RAM.

⚠️ This document reflects more of an ideal than reality right now.

1. Create the VM in Hetzner Cloud, get the IP, IPv6, set the SSH public key.
2. Create a new NixOS configuration in your flake:

{
  inputs.nixos-anywhere.url = "github:nix-community/nixos-anywhere";
  inputs.srvos.url = "github:nix-community/srvos"; 
  inputs.disko.url = "github:nix-community/disko";

  outputs = { self, nixos-remote, srvos, disko, nixpkgs }: {
    nixosConfigurations.my-host = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [{ 
        imports = [ 
          srvos.nixosModules.hardware-hetzner-cloud
          srvos.nixosModules.server

          # Are those together?
          disko.nixosModules.disko
          srvos.diskoModules.disk-layout-single-v1
        ];
        networking.hostName = "my-host";
        # FIXME: Hetzner Cloud doesn't provide us with that configuration
        systemd.network.networks."10-uplink".networkConfig.Address = "2a01:4f9:c010:52fd::1/128";
      }];
    };
    # TODO other $systems
    devShells.x86_64-linux.default = with nixpkgs.legacyPackages.x86_64-linux; mkShellNoCC {
      packages = [
        # TODO: add nixos-rebuild as a package
        nixos-anywhere.packages.x86_64-linux.default
      ];
    };
  };
}

1. Update the hostname and IPv6 address in the config.

2. Bootstrap the NixOS deployment:

   $ nix develop
   $ nixos-anywhere --flake .#my-host --target <ip>
   

🎉

1. Pick a nixos deployment tool of your choice! Eg:

$ nixos-rebuild --flake .#my-host --target <ip> switch
