docker-compose安装zk集群

$NODE1、$NODE2、$NODE3分别取值zk集群中的三节点的IP，分别使用2181、2182、2183作为容器绑定宿主机的端口，具体的示例docker-compose .yml文件如下：

version:'2'

services:

zk1:

image: zookeeper

restart: always

container_name: zk1

ports:

-"2181:2181"

        environment:

ZOO_MY_ID: 1

ZOO_SERVERS: server.1=$NODE1:2888:3888 server.2=$NODE2:2888:3888 server.3=$NODE3:2888:3888

zk2:

image: zookeeper

restart: always

container_name: zk2

ports:

-"2182:2181"

        environment:

ZOO_MY_ID: 2

ZOO_SERVERS: server.1=$NODE1:2888:3888 server.2=$NODE2:2888:3888 server.3=$NODE3:2888:3888

zk3:

image: zookeeper

restart: always

container_name: zk3

ports:

-"2183:2181"

        environment:

ZOO_MY_ID: 3

ZOO_SERVERS: server.1=$NODE1:2888:3888 server.2=$NODE2:2888:3888 server.3=$NODE3:2888:3888
