How can I add multiple hosts?

So currently, the nixosConfigurations block in flake.nix just iterates over the system types and creates flake targets automatically. You could remove this in favor of your own, specific targets. Then create files in hosts/nixos for each host.

Something like:

    nixosConfigurations = {
        host1 = nixpkgs.lib.nixosSystem {
          system = "x86_64-linux";
          specialArgs = inputs;
          modules = [
            disko.nixosModules.disko
            home-manager.nixosModules.home-manager {
              home-manager = {
                useGlobalPkgs = true;
                useUserPackages = true;
                users.${user} = import ./modules/nixos/home-manager.nix;
              };
            }
            ./hosts/nixos/host-1.nix
          ];
        };
        host2 = nixpkgs.lib.nixosSystem {
          system = "x86_64-linux";
          specialArgs = inputs;
          modules = [
            disko.nixosModules.disko
            home-manager.nixosModules.home-manager {
              home-manager = {
                useGlobalPkgs = true;
                useUserPackages = true;
                users.${user} = import ./modules/nixos/home-manager.nix;
              };
            }
            ./hosts/nixos/host-1.nix
          ];
        };
        # Add other hosts here in a similar manner
      };
    };

Then just check out the simple scripts to run build and build-switch. You'll see we just call a simple command nixos-rebuild switch to switch to a new Nix generation.

Your command would look like: /run/current-system/sw/bin/nixos-rebuild switch --flake .#host1

dustinlyons / nixos-config
