docker怎么部署etcd集群

本篇内容介绍了“docker怎么部署etcd集群”的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！

需要安装：

• docker

• dockerpose

参数详细：

• –name：设置成员节点的别名，建议为每个成员节点配置可识别的命名

• –advertise-client-urls：广播到集群中本成员的监听客户端请求的地址

• –initial-advertise-peer-urls：广播到集群中本成员的Peer监听通信地址

• –listen-client-urls：客户端请求的监听地址列表

• –listen-peer-urls：Peer消息的监听服务地址列表

• –initial-cluster-token：启动集群的时候指定集群口令，只有相同token的几点才能加入到同一集群

• –initial-cluster：所有集群节点的地址列表

• –initial-cluster-state：初始化集群状态，默认为new，也可以指定为exi-string表示要加入到一个已有集群

创建etcd数据目录

mkdir-p./etcd-node{1,2,3}

创建docker网络

dockernetworkcreate--driverbridge--subnet172.62.0.0/16--gateway172.62.0.1etcd-cluster

etcd-clusterpose.yml

启动并验证集群

验证集群

通过etcdctl member list命令可以查询出所有集群节点的列表并且结果一致即为成功
