# Simple example to show loading config from the cluster
#
# It works only from a pod. You can start an image with Python
# (for example python:latest), exec into the pod, install the library,
# then try out this example.
#
# If you get 403 errors from API server you will have to configure
# RBAC to add the permission to list pods.

You can’t perform that action at this time.
