I'm getting Failed to upload keys: I/O Error: No such file or directory (os error 2) when I try to upload keys. The key block is:

          deployment = {
            keys."myservice.secret" = {
              keyFile = /full/path/to/secrets/myservice.secret;
              uploadAt = "pre-activation";
            };
          };

Am I doing something obviously stupid? File is in the ./secrets dir by the flake, and owned by the same user

Yeah, on non-NixOS hosts the Nix binaries aren't in the PATH set up by sshd/pam. It's a long-standing issue: https://github.com/NixOS/nix/issues/1078

Hi! I'm new to NixOS, but want to try out Colmena as a means to set up some computers in my home. One of them is a Microsoft Surface Pro 3, which needs <nixos-hardware/microsoft/surface-pro/3> to function properly. However, I'm struggling to use that with Colmena.

What I have now is something like this:

flake.nix
machines

• surface-configuration.nix
• surface-hardware-configuration.nix

In flake.nix:

inputs = { nixpkg.s.url = ... };

And machines/surface-configuration.nix is the /etc/nixos/configuration.nix file copied from the surface after a fresh install. It, in turn, imports machines/surface-hardware-configuration.nix, which I've also left as default.

From this, I first get an error error: cannot look up '<nixos-hardware/microsoft/surface-pro/3>' in pure evaluation mode (use '--impure' to override), so I use --impure, but then get error: file 'nixos-hardware/microsoft/surface-pro/3' was not found in the Nix search path (add it using $NIX_PATH or -I. I should probably add it the proper way with a url to nixos-hardware as shown in the nixos-hardware section on flakes, but I'm not sure where to stick in those modules ref: (nixos-hardware#flakes)[https://github.com/NixOS/nixos-hardware#using-nix-flakes-support].

Does anyone know how I should proceed?

hit enter too soon... hold on

Done :)

I wouldn’t use the impure mode here. The syntax with brackets is not what you want with flakes. You will need to add nixos-hardware as a flake input instead.

If that doesn’t make sense I can give a more complete example when I’m back at my computer. 

I was eventually able to create a flake wrapper around my existing config, which seems to work. At least nix build .#nixosConfigurations.surface.config.system.build.toplevel succeeds.

So I think it's now just about importing that into the Colmena flake? I've tried a few variations of the below colmena flake, but to no avail.

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    surface.url = "/home/sivert/work/nixos-surface";
  };
 
  outputs = {nixpkgs, surface, ...}: {
    colmena = {
      meta = {
          nixpkgs = import nixpkgs {
            system = "x86_64-linux";
          };
      };
 
      surface = { name, ...}: {
 
        deployment = {
          targetHost = "surface";
          targetUser = "nixos";
        };
        
        networking.hostName = "surface";
 
        imports = [
          surface #.nixosConfigurations.surface.config.system.build.toplevel
          ];
      };
    };
  };
}
