出现这种情况：

[preflight] FYI: You can look at this config file with 'kubectl -n kube-system get cm kubeadm-config -o yaml'
[kubelet-start] Writing kubelet configuration to file "/var/lib/kubelet/config.yaml"

To see the stack trace of this error execute with --v=5 or higher

这是因为我最初初始化主节点的时候加入了该节点，然后kubeadm reset了，，需要初始化一下node节点才能成功，具体执行操作如下：

kubelet reset一下，然后发现node节点还是notready，journalctl  -f -u kubelet命令查看，出现如下：
