+Synopsis
+
+Generates the client certificate for liveness probes to healtcheck etcd, and saves them into etcd/healthcheck-client.cert and etcd/healthcheck-client.key files.
+
+If both files already exist, kubeadm skips the generation step and existing files will be used.
+
+Alpha Disclaimer: this command is currently alpha.

+
+概要
+
+为探查healthcheck etcd的活跃度生成客户端证书，并且保存为 etcd/healthcheck-client.cert 以及 etcd/healthcheck-client.key 两个文件。
+
+如果两个文件都已经存在，kubeadm 将会跳过生成的步骤并且使用已经存在的文件。
+
+Alpha免责声明：这个指令现在是alpha版。
