这是一个后续问题。我做到了以下几点：
为我的5代理kafka集群创建一个无头服务，用于代理间通信
为每个代理设置一个服务
每个服务都有一个外部ip
每个服务只选择一个吊舱，例如服务“kafka-0-es”选择吊舱“kafka-0”
pod正确地公布它们各自的外部ip。我通过访问zookeeper cli上的数据来验证这一点。
我创建了一个主题 test-topic 使用zkcli并验证它是否已创建。之后，我开始制作Kafka游戏机。

.\kafka-console-producer.bat --broker-list EXTERNAL_IP_1:9093,EXTERNAL_IP_2:9093,EXTERNAL_IP_3:9093,EXTERNAL_IP_4:9093,EXTERNAL_IP_5:9093 --topic test-topic --property parse.key=true --property key.

zookeeper称，我的Kafka经纪人“Kafka-2”是这个主题的领导者：

get /kafka/brokers/topics/test-topic/partitions/0/state

{"controller_epoch":5,"leader":2,"version":1,"leader_epoch":0,"isr":[2,1]}

但是Kafka-2号吊舱在日志中出现了错误

[2018-05-09 15:21:02,524] ERROR [ReplicaFetcherThread-0-2], Error for partition [test-topic,0] to broker 2:org.apache.kafka.common.errors.UnknownTopicOrPartitionException: This server does not host this topic-partition. (kafka.server.ReplicaFetcherThread)

不太清楚为什么会发生这种情况，配置看起来不错。还有什么我错过了让我的Kafka集群运行在库伯尼特斯？
注意，我也尝试过完全擦除我的集群（scale-down kafka cluster，delete kafka storage，scale-down zk cluster，delete zk storage，scale-up zk，scale-up kafka），但没有效果。
