   ##### SUMMARY
   <!-- Explain the problem/feature briefly -->
   
   When a kubernetes cluster is spinned up metric API is not available. We will have to configure metric API manually. Without metric API horizontal pod auto scale will not work and also kubernetes admin won't able to know the utilisation each pod and node is accuring.
   
   There are different way to enable metric API but I feel more easy on below steps.
   
   Step 1 : Check metric API
                 kubectl top nodes
                 (it will show metric API not available error)
   
   Step2: Install metric API from kubernetes git
                kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml
   
   Step 3: Check metric pod is running
               Kubectl -n kube-system get pods
   
   Step 4: Edit metric server deployement and below line
                kubectl -n kube-system edit deploy metrics-server 
                <Add below lines after metric-resolution=15s in containers tag>
                command:
           - /metrics-server
           - --kubelet-insecure-tls
           - --kubelet-preferred-address-types=InternalIP
           
   Step 5: Check metric API
               kubectl top nodes
   
   ##### STEPS TO REPRODUCE
   <!--
   For bugs, show exactly how to reproduce the problem, using a minimal test-case. Use Screenshots if accurate.
   
   For new features, show how the feature would be used.
   -->
   
   Just bring up a cluster and type kubectl top nodes command will get metric API unavailable message
   
   ##### EXPECTED RESULTS
   <!-- What did you expect to happen when running the steps above? -->
   
   If a user bring up a kubernetes cluster they should get maximum componenets on cluster so that they don't want to go around for each. If any changes on this can be done please do the needful so it can help users using kubernetes on cloudstack

   This isn't supported yet or even need to be supported; the k8s side dashboard may be more appropriate for cluster-specific metrics observations.

   This is good improvement request, as it best way to scrape metrics from a kubernetes cluster
   
   Other Public clouds,  support metric server installation on the k8s cluster
