How to enable metrics server in minikube

Metrics server is a component that allows you to view the metrics of your cluster. If you would like to experiment with Horizontal Pod Autoscaling (HPA), metrics server is a necessary component in Minikube.

Within minikube, metrics-server is available as a add-on. If it is not enabled already, you can enable it by running the following command:

minikube addon enable metrics-server

Once it is enabled, you can view the metrics of a running pod using the following command:

kubectl top pods

This will show CPU and memory usage of the running pod.
