-使用此命令，您可以使用与 ‘kubeadm init’ 相同的配置文件将配置上传到集群中的 ConfigMap。
-如果您使用的是 v1.7.x 或更低版本的 kubeadm 客户端初始化集群并且使用了 --config 选项，那么在使用 'kubeadm upgrade' 升级到 v1.8 之前，您需要使用相同的配置文件运行此命令。
-<!--
-Using this command, you can upload configuration to the ConfigMap in the cluster using the same config file you gave to 'kubeadm init'.
-If you initialized your cluster using a v1.7.x or lower kubeadm client and used the --config option, you need to run this command with the
-same config file before upgrading to v1.8 using 'kubeadm upgrade'.
