我想在google kubernetes engine上想部署java web服务，请问在cloud上zookeeper的ip怎么设置

用docker起zookeeper服务，在本地环境java web服务是没问题的，但是一旦在k8s上运行后，java web所运行的pod就无法连接docker上的zookeeper

注册完zookeeper
$ docker container ls
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
b99c41f81335 zookeeper:3.5 “/docker-entrypoint.…” 8 minutes ago Up 8 minutes 2888/tcp, 3888/tcp, 0.0.0.0:2181->2181/tcp, 8080/tcp nostalgic_nash

查看zookeeper的ip address
$ docker inspect b99c4
"Networks": {
“bridge”: {
“IPAMConfig”: null,
“Links”: null,
“Aliases”: null,
“NetworkID”: “a03e6772fc858a1e14847f0d2a8edcb2d0ee39ddb2449f5f62b89da73d54ce51”,
“EndpointID”: “53d85011cb72cd74dd8d7bd6c469a5f6416c11ec959ad22f86ad9904a9c1ded8”,
“Gateway”: “172.18.0.1”,
“IPAddress”: “172.18.0.2”,
“IPPrefixLen”: 16,
“IPv6Gateway”: “”,
“GlobalIPv6Address”: “”,
“GlobalIPv6PrefixLen”: 0,
“MacAddress”: “02:42:ac:12:00:02”,
“DriverOpts”: null
}
}
配置好web服务的zookeeper的ip
cat ./WEB-INF/classes/applicationContext-service-config.xml

    <dubbo:application name="demo" />
    <dubbo:registry address="zookeeper://172.18.0.2:2181" />
    <dubbo:consumer retries="3" timeout="60000" />

用docker启动web服务
docker run -it gcr.io/lithe-sonar-276007/web:v1

ete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.
