Tips

  1. Since all slave nodes have no capability of storing in kubernetes, it means that kubelet has to request api-server in period.

  2. Once slave node was registered to cluster, it no way reconfigure some features by restarting kubelet, for example labeling node by --node-label option when start kubelet. However, if slave node is deleted by administrator(kubectl delete node $NODE_NAME) from cluster, slave node can rejoin cluster by restarting cluster, also some reconfigurable features will active.
