# 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 cluster components.

# This TLS & bearer token file config is used to connect to the actual scrape
|
|
# endpoints for cluster components. This is separate to discovery auth
|
|
# configuration (`in_cluster` below) because discovery & scraping are two

|
# separate concerns in Prometheus.

# Scrape config for services.

#
|
|
# The relabeling allows the actual service scrape endpoint to be configured
|
|
# via the following annotations:
|
|
#
|
|
# * `prometheus.io/scrape`: Only scrape services that have a value of `true`
|
|
# * `prometheus.io/scheme`: If the metrics endpoint is secured then you will need
|
|
# to set this to `https` & most likely set the `tls_config` of the scrape config.
|
|
# * `prometheus.io/path`: If the metrics path is not `/metrics` override this.
|
|
# * `prometheus.io/port`: If the metrics are exposed on a different port to the
|
|
# service then set this appropriately.
