一直报错：
1 partitions have leader brokers without a matching listener, including [cloudeasy.cmdb.cancel.manage-0]
查看zk服务端，报错如下：
原因是 watch 太多且路径太长导致重连的时候超过了 ZK maxBuffer 的限制
把 客户端从 3.4.6 升级到 3.4.7 就能解决这个问题
先部署zookeeper，默认docker不需要参数，域名访问地址为zookeeper-dev.cmsp-dev.svc.cluster.local:2181
docker 部署kafka(2.12-2.5.0)，启动参数如下：
sh
-c
exec kafka-server-start.sh /opt/kafka/config/server.properties --override advertised.host.name=zookeeper-dev.cmsp-dev.svc.cluster.local --override broker.id=-1 --override listeners=PLAINTEXT://:9092 --override advertised.listeners=PLAINTEXT://kafka-dev.cmsp-dev.svc.cluster.local:9092 --override zookeeper.connect=zookeeper-dev.cmsp-dev.svc.cluster.local:2181
./kafka-topics.sh --create --topic cloudeasy.dev.mess --replication-factor 1 --partitions 1 --zookeeper zookeeper-dev.cmsp-dev.svc.cluster.local:2181
./kafka-topics.sh --list --zookeeper zookeeper-dev.cmsp-dev.svc.cluster.local:2181
./kafka-topics.sh --delete --topic cloudeasy.dev.mess --zookeeper zookeeper-dev.cmsp-dev.svc.cluster.local:2181
如果删不掉，可以在zookeeper里删除
deleteall /brokers/topics
开发环境创建topic：
./kafka-topics.sh --create --topic cloudeasy.dev.mess --replication-factor 1 --partitions 1 --zookeeper zookeeper-dev.cmsp-dev.svc.cluster.local:2181
./kafka-topics.sh --create --topic cloudeasy.billing.executor --replication-factor 1 --partitions 1 --zookeeper zookeeper-dev.cmsp-dev.svc.cluster.local:2181
./kafka-topics.sh --create --topic cloudeasy.cloudmanager.event --replication-factor 1 --partitions 1 --zookeeper zookeeper-dev.cmsp-dev.svc.cluster.local:2181
./kafka-topics.sh --create --topic cloudeasy.cmdb.cancel.manage --replication-factor 1 --partitions 1 --zookeeper zookeeper-dev.cmsp-dev.svc.cluster.local:2181
./kafka-topics.sh --create --topic cloudeasy.cmdb.delete.resource --replication-factor 1 --partitions 1 --zookeeper zookeeper-dev.cmsp-dev.svc.cluster.local:2181
./kafka-topics.sh --create --topic cloudeasy.cmdb.update.project --replication-factor 1 --partitions 1 --zookeeper zookeeper-dev.cmsp-dev.svc.cluster.local:2181
./kafka-topics.sh --create --topic cloudeasy.user.event --replication-factor 1 --partitions 1 --zookeeper zookeeper-dev.cmsp-dev.svc.cluster.local:2181
查询有哪些客户端group
kafka-consumer-groups.sh --bootstrap-server localhost:9092 --list
查询指定group的消费情况
kafka-consumer-groups.sh --bootstrap-server localhost:9092 --group cloudeasy --describe
./kafka-consumer-groups.sh --bootstrap-server localhost:9092 --describe --group cloudeasy.billing.consumer
kafka-consumer-groups.sh --bootstrap-server localhost:9092 --describe --group cloudeasy.monitor.group
客户端kafka报错问题：

1 partitions have leader brokers without a matching listener，没有主broker了
./kafka-topics.sh --list --zookeeper zookeeper.cmsp-dev.svc.cluster.local:2181
./kafka-topics.sh --zookeeper zookeeper.cmsp-dev.svc.cluster.local:2181 --describe --topic cloudeasy.cmdb.update.project
显示Leader:-1 选主有问题
解决leeder为-1问题，连接zookeeper
