Gardener Extensions Configuration

Other than the core Gardener components, Gardener extensions are configured through a 23KE internal helm chart. Consequently, you cannot retrieve any information about possible values via e.g. the helm cli. For this reason the extension-values Secret is documented here. As the other configuration secrets, the secret's header looks like the following:

apiVersion: v1
kind: Secret
metadata:
  name: extensions-values
  namespace: flux-system
type: Opaque
stringData:
  values.yaml: |
  ...
