Because a dokcer not start, leading kubelet can not start
Solution: First check whether the normal start docker, if docker also can not start, you need to start docker, before you can start kubelet
if docker not start, the solution rm -rf / var / lib / docker / docker and then start again, can be found start, and then start kubelet
Two for no reason my kubelet service is stopped, and found not start,

Solutions: Then I restarted the docker, discovery can start, but I still can not start kubelet start,
finally, because docker and kubelet driver inconsistency caused
See docker drive, with docker info, following FIG.
Check the type of drive kubelet
If inconsistencies are kubelet not start
