-    # Kubernetes labels will be added as Prometheus labels on metrics via the
-    # `labelmap` relabeling action.

-    # service so this uses `endpoints` role and uses relabelling to only keep
-    # the endpoints associated with the default/kubernetes service using the
-    # default named port `https`. This works for single API server deployments as
