Headlamp plugins using helm chart

[mtotone]

Hello everyone,

I installed Headlamp on a Kubernetes cluster using the Helm chart.

Starting from version 0.31.0, it's possible to manage plugins using the pluginsManager field (ref).

I added the following values:

pluginsManager:
  enabled: true
  configContent: |
    plugins:
      - name: cert-manager
        source: https://artifacthub.io/packages/headlamp/headlamp-plugins/headlamp_cert-manager
        version: 0.1.0
      - name: trivy
        source: https://artifacthub.io/packages/headlamp/headlamp-trivy/headlamp_trivy
        version: 0.3.1
    installOptions:
      parallel: true
      maxConcurrent: 2

In the plugin installer container logs, I see:

info: Installing plugins from config: /config/plugin.yml

1 of 2 (cert-manager): info: Fetching Plugin Metadata

Watching /config/plugin.yml for changes...

However, in the web UI, no plugins appear.

Has anyone successfully gotten plugins to work using the Helm chart? Am I missing something?

Thanks.

Hey,
Did you also enable watch in your config ? It is required so that main container can watch the changes in plugin-directory
Reference: https://headlamp.dev/docs/latest/installation/in-cluster/#auto-updating-plugins

config:
  watchPlugins: true  # Set to true to enable automatic plugin updates in main headlamp container
