title: Unable to get kubelet config by alpha phase
body: <p>I'm trying to get kubelet config.yaml file on my broken production cluster with no luck. The command I am using is:</p>
  
  <pre><code>kubeadm alpha phase kubelet config write-to-disk --config=/var/lib/kubelet/config.yaml
  </code></pre>
  
  <p>This returns the following error:</p>
  
  <pre><code>no InitConfiguration or ClusterConfiguration kind was found in the YAML file
  </code></pre>
  
  <p>Could somebody please help me resolve this? Thanks.</p>
