Is it possible to deploy a single host?

[busti]

How do I deploy a single host only or alternatively make the deployment not fail when a host cannot be reached?

[infinisil]

I believe $(nix-build -A myHost) should work because of

nixus/build.nix

Line 58 in 5257be6

// nixusPkgs.lib.mapAttrs (n: v: v.deployScript) result.config.nodes

:)

Could you please also give an example of how to do it with flakes?

[infinisil]

Taking #54 as the base, something like

apps =
  {
    default = flake-utils.lib.mkApp {
      drv = self.packages.${system}.deployer;
      exePath = "";
    };
  }
  // nixpkgs.lib.mapAttrs' (name: value: {
    name = "node-${name}";
    value = flake-utils.lib.mkApp {
      drv = value.deployScript;
      exePath = "";
    };
  ) self.packages.${system}.deployer.config.nodes;

should work for nix run .#node-myHost :)
