# 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. |
|
# |
|
# If you are using Kubernetes 1.7.2 or earlier, please take note of the comments |
|
# for the kubernetes-cadvisor job; you will need to edit or remove this job. |
|
|
|
# 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. |
