You can see pod metrics using this command:

If you have some issue then you can add the following command attributes in your “metrics-server-deployment file” under “containers” section.
command:
- /metrics-server
- --metric-resolution=30s
- --kubelet-insecure-tls=true

So, your deployment file will look like this:
containers:
- name: metrics-server
command:
- /metrics-server
- --metric-resolution=30s
- --kubelet-insecure-tls=true
imagePullPolicy: IfNotPresent

$ minikube addons enable metrics-server
$ minikube addons list

$ kubectl get pods -n kube-system

$ kubectl get all
$ watch -n1 !!
