title: kubelet dynamic configuration doesn't work

  Hi, I got some troubles in following this tutorial. It is recommended to reconfigure the kubelet with configmap, but when i use "kubectl edit node " to modify the kubelet configuration, nothing changed though the output showing "node *** edited", and the ConfigOk status did not show up in the node status. For more info, the configmap, corresponding role and rolebinding can be all created successfully. Is there anything i have missed or this tutorial needs to be updated?
  I have tried so many times and it stucked in the <a href="https://kubernetes.io/docs/tasks/administer-cluster/reconfigure-kubelet/#observe-that-the-node-begins-using-the-new-configuration" rel="nofollow noreferrer">Observe that the Node begins using the new configuration</a> step. I wanna know if it's needed to set the node into the system:node group or anything else did i miss? Thanks!</p>
