charts/headlamp: Fix for pluginctl without global install

[illume]

Because there is no permission to do that now. So we run it without installing it.

For

• Headlamp 0.36.0: Plugin manager sidecar crashes with npm permissions error #3999

Testing

1. Deploy Headlamp using Helm chart version 0.36.0

Enable plugin manager:

Put in values.yml

pluginsManager:
  enabled: true
  configContent: |
    plugins:
      - name: flux
        source: https://artifacthub.io/packages/headlamp/headlamp-plugins/headlamp_flux
        version: 0.5.0

Use the local chart instead of the one in the repo.

helm install my-headlamp charts/headlamp --namespace kube-system -f values.yml

3. Check pod status: kubectl get pods -n headlamp
4. Before you would see CrashLoopBackOff with 1/2 Ready, with this it will say something like my-headlamp-58789b6df-8cpwn 2/2 Running 0 0m11s.
5. Check logs: kubectl logs <pod> -c headlamp-plugin There should be a success message not a failure one.

@yolossn please review?

unrelated to this PR but the initcontianer is failing.

The configmap that is created from the pluginConfig has an empty line in the beginning.

@illume I tried reproducing this in helm playground.

@yolossn Thanks for testing and the review.

@illume I tried reproducing this in helm playground.

Neat tool. I updated the config so it does not render with the new lines. Could you please have a look?

[yolossn]

Now the plugin is getting created in the path correctly. The plugins are not getting loaded by headlamp because there is a race condition. The server is getting started even before the plugin is downloaded. Ideally the watchPlugins should be set to true if pluginManager is enabled. Since this is unrelated we can fix this in a new PR

Sorry, yes... this is because we need the watch config which I forgot to mention in the testing. But it's documented already.

Thanks @yolossn
