这里我们分别为
node0/node1/node2开放宿主机的
9200/9201/9202作为
http服务端口，各实例的
tcp数据传输用默认的
9300通过容器管理通信。如果需要多机部署，则将
ES的
transport.tcp.port: 9300端口映射至宿主机
xxxx端口，
discovery.zen.ping.unicast.hosts填写各主机代理的地址即可：
#比如其中一台宿主机为192.168.1.100
...
- "discovery.zen.ping.unicast.hosts=192.168.1.100:9300,192.168.1.101:9300,192.168.1.102:9300"
...
ports:

- 9300:9300创建并启动服务
