We can start with:

kubectl get no

  // For all the confusing Prometheus configuration and
  // regular expressions,
  // explained in examples.


  // Remember, there are default values for each item if it's missing.
  // regex is (.*),
  // replacement is $1,

# This script ports deployed Helm v2 Packages from k8s API v1.15 to 1.16
#
# When upgrading K8s clusters to a new minor API version it is possible that
# already deprecated API Endpoints are removed e.g.,
# extensions/v1beta1/DaemonSet
# K8s handles this transparently for already deployed ressources from the
# deprecated paths, making them available via their new API. They are no longer
# available through the removed paths though.
