# this is an example extending Kubeclient::Client with an get_pod_exec method
# 
# it's just a POC
# I did run a pod with `kubectl -n kube-system run --tty --stdin --image=debian:buster-slim kubeclient`
# installed base ruby and required gems like: 
# `apt-get update && apt-get install -y ruby ruby-dev build-essential && gem install --no-ri --no-rdoc kubeclient websocket-client-simple`
