Helm plugins don't appear to work in devbox

[Shane Starcher]

What happened?

In my devbox global

* kubernetes-helm@latest
* kubernetes-helmPlugins.helm-diff@latest

  eval "$(devbox global shellenv --init-hook)"

❯ helm plugin list
NAME	VERSION	DESCRIPTION

❯ helm diff
Error: unknown command "diff" for "helm"
Run 'helm --help' for usage.

Steps to reproduce

1. devbox global add kubernetes-helmPlugins.helm-diff
2. devbox global add kubernetes-helm
3. helm plugin list

I would expect the plugin to be installed

Note: this is how they're handled in nix directly: https://nixos.wiki/wiki/Helm_and_Helmfile

My knowledge of nix is very limited working on that. I would have expected what I did above with

   "kubernetes-helmPlugins.helm-diff@latest",

to be equivalent of what they recommended below in nix or are you saying I should create a flake and have it referenced by devbox?

{
  environment.systemPackages = with pkgs; [
      (wrapHelm kubernetes-helm {
        plugins = with pkgs.kubernetes-helmPlugins; [
          helm-secrets
          helm-diff
          helm-s3
          helm-git
        ];
      }) 
    ];
}

It won't be equivalent. I believe jetpack would need to special case this.

I believe if you make a flake as you mentioned, this will work.

I'm on a m2 macbook. I tried searching for the relevant devbox/nix docs. The invocation of flake-utils.lib.eachDefaultSystem when I hunted down the readme for that library.

With the config pulled from the nixos wiki I get the following error. I apologize for being a complete noob.

Error: error installing package path:.devbox/flakes
source: nix path-info exit code: 1, output: warning: creating lock file '/Users/jameshounshell/git/ml/helm-charts/.devbox/flakes/flake.lock'

Oh my goodness I ditched the flake thing and got it to work by hackily supplying the HELM_PLUGIN environment variable
