Kubernetes Horizontal Pod Autoscaler | HPA | AWS EKS Tutorial

Описание: We're diving into the Horizontal Pod Autoscaler with hands on demos,
First demo, we will Use command line to create a Horizontal Pod Autoscaler,
and run load testing in nginx service to check HAP status.
Second demo, we will create another HPA with Behavior speck,
and run the same load testing again to check HAP status.

The minikube is used in my demo so demo has 0 cost.
