Kubectl output options

Let's look at some basic kubectl output options.

Our intention is to list nodes (with their AWS InstanceId) and Pods (sorted by node).

We can start with:

kubectl get no

local https://github.com/kubernetes-sigs/kind (or just use minikube if it works for you)
cloud https://cloud.google.com/kubernetes-engine (for PersistentVolume and Ingress, I needed to try the real deal)
practice environment: https://github.com/arush-sal/cka-practice-environment

	Below are the Big O performance of common functions of different Java Collections.
