+# A scrape configuration for running Prometheus on a Kubernetes cluster.
+# This uses separate scrape configs for cluster components (i.e. API server, node)
+# and services to allow each to use different authentication configs.
+#
+# Kubernetes labels will be added as Prometheus labels on metrics via the
+# `labelmap` relabeling action.
+
+# Scrape config for API servers.
+#
+# Kubernetes exposes API servers as endpoints to the default/kubernetes
+# 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
+# well as HA API server deployments.
