          If using a Kubelet config file, edit $kubeletconf to set authentication: anonymous: enabled to
          false.
          If using executable arguments, edit the kubelet service file
          $kubeletsvc on each worker node and
          set the below parameter in KUBELET_SYSTEM_PODS_ARGS variable.
          --anonymous-auth=false
          Based on your system, restart the kubelet service. For example:
          systemctl daemon-reload
          systemctl restart kubelet.service

          Edit any manifest files or $kubeletconf that contain the feature-gates
          setting with AllAlpha set to "true".
          Set the flag to "false" or remove the "AllAlpha" setting
          completely. Restart the kubelet service if the kubelet config file
          if the kubelet config file is changed.
