title: metrics-server no metrics known for pod error during deployment
body: <p>I have a newly created AWS EKS 1.18 Cluster, applications are deployed on it, everything is fine, test and load test are successful, namely, my HPA and metrics-server is working fine.</p>
  <p>But when I make a deployment to a service, metrics-server is giving
  <code>unable to fetch pod metrics for pod xxx: no metrics known for pod</code> for the newly deployed pod, then problem is being resolved and everything is fine again.</p>
  <p>My question is, is this an expected behaviour for metrics-server? Or should I check my configs again?</p>
  <p>Thank you very much.</p>
