Hi, I've recently found this project and was wondering if it's possible to just replace an existing deploy-rs setup with Colmena or would it cause some issues?

In reply to @luna:bddvlpr.com
Well besides reconfiguring the config structure, I’ve tried replacing deploy-rs’ flake structure with colmena’s but ran into some troubles. I’m guessing it’s because of the experimental flake support but haven’t had the time to properly look into it yet.

I did the opposite for some of my machines recently to test deploy-es and had no issue. Feel free to post the log here next time.

think I figured it out, or atleast it seems to work:

outputs = {nixpkgs, ...}:
  let
    hosts = nixpkgs.lib.mapAttrs'
      (filename: _: {
        name = nixpkgs.lib.nameFromURL filename ".";
        value = [ ./hosts/${filename} ];
      })
      (builtins.readDir ./hosts);
  in {
    colmena = hosts // {
      # ...
    };
};

In reply to @ser:sergevictor.eu
can colmena secrets deploy a whole directory, not single files only?

What tool do you people think would fit well with Colmena when deploying bare metal?

Oh my bad, I forgot --experimental-flake-eval, this is the log I get:

Is disko perhaps not compatible with colmena?

In reply to @ibizaman:matrix.org
Any tool should be compatible. I used nixos-anywhere successfully and heard about nixos-infect working too. I’ve got a flake template for the former https://github.com/ibizaman/skarabox if you want some inspiration.

In reply to@ibizaman:matrix.org
There are two errors at the end there, setting root filesystem and grub stuff. Usually those come from running the hardware generator on the new machine and that gets you a hardware-configuration.nix file. You must include that file or recreate the options it is setting for the configuration to be happy.

{
  self,
  inputs,
  ...
}: let
  inherit (self) outputs;
  inherit (builtins) mapAttrs;
in {
  flake = {
    colmena =
      (mapAttrs (host: value: {
          deployment = {
            targetHost = "${host}.cloud.bddvlpr.com";
          };
        })
        outputs.nixosConfigurations)
      // {
        meta = {
          nixpkgs = import inputs.nixpkgs {
            system = "x86_64-linux";
            overlays = [];
          };
        };
      };

    colmenaHive = inputs.colmena.lib.makeHive outputs.colmena;
  };
}
