$NODE1、$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
