Deployment

To define and deploy a machine (called twinpeaks in this example), do the following.

1. Put its configuration under machines/twinpeaks.
2. Create an outputs.nixosConfigurations.twinpeaks block in flake.nix. If necessary, define its network configuration in intranet/devices.nix and intranet/wireguard.nix.
3. Start the machine and its SSH server to generate an SSH host key.
4. Obtain the host key.

   $ ssh-keyscan <ip-address>
   

5. Follow the instructions in the infra-secrets repository.
6. SSH into the machine and enter a Nix shell with git (the flake setup needs it).

   $ nix shell nixpkgs#git
   

7. Run

   # nixos-rebuild switch --flake 'github:tomaskala/infra#twinpeaks'
   

   Explicitly setting the flake is only necessary during the initial deployment. Afterwards, the hostname will have been set and nixos-rebuild will automatically select the matching flake.
