* k8s: Support discovery of ingresses * Move additional labels below allocation This makes it more obvious why the additional elements are allocated. Also fix allocation for node where we only set a single label. * k8s: Remove port from ingress discovery * k8s: Add comment to ingress discovery example

# 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.
