how can i pass different key for each host in colmena ?

maybe use ~/.ssh/config to configure which hosts should use which key. Or is ssh-ng ignoring that?

Hi Zhaofeng Li !

I beleive colmena eval was only ever made to be impure (so the --impure option might be a mistake), see:

    introspect = f:
      f {
        lib = nixpkgs.lib // builtins;
        pkgs = nixpkgs.legacyPackages.${builtins.currentSystem};
        nodes = l.mapAttrs (evalNode {_module.check = false;}) comb;
      };

        nodes = l.mapAttrs (evalNode {_module.check = false;}) comb;
      };

So I made use of the new colmenaHive output 🦾

That's a super nice iface, imo.

What I do not understand as much as I try, is why I get an infinit recursion when I try to freeformType evaluate the entire configuration, including all imports. https://github.com/divnix/hive/blob/main/make-honey.nix#L83-L85

In the unlikely event that somebody is keen on helping with an infinite recursion, here are the neuralgic points of the trace:

Hi Zhaofeng Li !

I beleive colmena eval was only ever made to be impure (so the --impure option might be a mistake), see builtins.currentSystem in:

    introspect = f:
      f {
        lib = nixpkgs.lib // builtins;
        pkgs = nixpkgs.legacyPackages.${builtins.currentSystem};
        nodes = l.mapAttrs (evalNode {_module.check = false;}) comb;
      };

Ah, it's in your make-honey.nix, missed it. But the options should be passed correctly and there is no --impure:
