# 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.
