ETCD更新集群成员信息

这个操作常用于自动发现建立集群，然后在起来之后需要修改数据信息使用

 

[root@master1 ~]# etcdctl member list --endpoints="https://172.21.130.169:2379,https://172.21.130.168:2379,https://172.28.17.85:2379" --write-out=table
+------------------+---------+--------+-----------------------------+-----------------------------+------------+
