Is there a specific reason for why colmena diverges from the "standard" flake output schema? (For reference: https://nixos.wiki/wiki/Flakes#Output_schema )

In reply to @zhaofeng:zhaofeng.li
It also provides a clear upgrade path for users using legacy hive.nix to flakes

Also regarding upgrading to flakes, note that Colmena can auto-call if hive.nix evaluates to a function, allowing you to do things like this:

{ pkgs ? import <nixpkgs> { system = "x86_64-linux"; } }: # or how you pin your nixpkgs
{
  meta = { ... };
}

and importing it like outputs.colmena = import ./hive.nix { pkgs = ...; }; in your flake. You can then deploy with either flake.nix and hive.nix during your transition period.

Does this work for you?

colmena.my-host = { name, nodes, ... }:
{
   imports = [ self.nixosConfigurations.my-host ];
}; 

(if you get an error that deployment options are undefined, import colmena.nixosModules.deploymentOptions in your nixosConfiguration)

        deployment.allowLocalDeployment = true;
        nixpkgs.system = self.nixosConfigurations.x2100.config.nixpkgs.system;
        imports = self.nixosConfigurations.x2100.extraArgs.modules ;
      };

colmena.node-a = {
        deployment.allowLocalDeployment = true;
        nixpkgs.system = self.nixosConfigurations.x2100.config.nixpkgs.system;
        imports = self.nixosConfigurations.x2100.extraArgs.modules ;
      };

nixosConfigurations.x2100 = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      specialArgs = { inherit inputs; };
      modules = [
          module-a
     ];
};

colmena.node-a = {
        deployment.allowLocalDeployment = true;
        nixpkgs.system = self.nixosConfigurations.node-a.config.nixpkgs.system;
        imports = self.nixosConfigurations.node-a.extraArgs.modules ;
      };

nixosConfigurations.node-a = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      specialArgs = { inherit inputs; };
      modules = [
          module-a
     ];
};

colmena.node-a = {
        deployment.allowLocalDeployment = true;
        nixpkgs.system = self.nixosConfigurations.node-a.config.nixpkgs.system;
        imports = self.nixosConfigurations.node-a.extraArgs.modules ;
      };

nixosConfigurations.node-a = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      specialArgs = { inherit inputs; };
      modules = [
          module-a
          #inputs.colmena.nixosModules.deploymentOptions
     ];
};

Im also realize while playing with colmena/nixosConfigurations outputs that colmena are impure builds. Is there some option to force pure builds??

In reply to @pacien:pacien.net
hello, is it possible to define specialArgs per node? I'd like to "inject" some attributes which depend on different values of system

In reply to @winterqt:nixos.dev
but i'm curious why impure is passed by default, i only see it mentioned there and in a test, cc Zhaofeng Li
