namespaceLabels does not work as a targetCustomizations

[jhoblitt]

Is there an existing issue for this?

• [X] I have searched the existing issues

Current Behavior

I attempted to add additional namespace labels as targetCustomizations[0].namespaceLabels and no change was made to the existing labels on the default namespace.

Expected Behavior

I expected either the top level namespaceLabels to merged with targetCustomization namespaceLabels or overridden completely. I did not expect nothing at all to happen as namespaceLabels is part of BundleDeploymentOptions.

Steps To Reproduce

---
defaultNamespace: &name mimir
labels:
  bundle: *name
namespaceLabels:
  foo: bar
helm:
  chart: &chart mimir-distributed
  releaseName: *chart
  repo: https://grafana.github.io/helm-charts
  version: 5.2.0
  timeoutSeconds: 600
  waitForJobs: true
targetCustomizations:
  - name: ruka
    clusterName: ruka
    helm:
      valuesFiles:
        - overlays/ruka/values.yaml
    namespaceLabels:
      this.is/a: test

Is this possibly related to #1994?

This is not supported yet: https://fleet.rancher.io/gitrepo-targets#supported-customizations

[jhoblitt]

My use case for wanting to customize namsepaceLabels is to use different prometheus scraping labels on different groups of clusters.

Closing this as we're tracking the feature in https://github.com/rancher/fleet/issues/2441
