  <pre><code>spec:
        containers:
        - command:
          - /metrics-server
          - --kubelet-preferred-address-types=InternalIP
          - --kubelet-insecure-tls
          - --logtostderr
  </code></pre>
  
  <p>The metrics-server logs reported with error and not able to use it for pods. Any Idea how to resolve this error</p>
