一、查看集群节点
etcdctl --endpoint=https://10.2.0.6:2379 --ca-file=/etc/etcd/ca.pem --cert-file=/etc/etcd/client.pem --key-file=/etc/etcd/client-key.pem member list
二、允许集群新增节点
kubectl member add <name> <peer-url>
三、启动新节点
--initial-cluster-state=existing
四、删除节点
etcdctl member remove c80cd07cd38b1e10
其中 c80cd07cd38b1e10 是老节点在集群中的id
