Kafka producer错误“1个分区有领导者代理，但没有匹配的侦听器”

Question

第一次与Kafka和多克合作。我正试图向Kafka发布一条消息，但出现了一个错误（请看下面）。问题是什么？

2020-07-21 16:37:40274警告[Kafka制作人网络线程|制作人-1]组织。阿帕奇。Kafka。客户。NetworkClient$DefaultMetadataUpdater:[Producer-clientId=Producer-1]1个分区的前导代理没有匹配的侦听器，包括[demo-topic-0]

Answer 1

我的问题在这里得到了部分回答，没有Kafka匹配的监听器错误。

docker-compose rm -sfv

上述代码最终解决了多个消费者的问题。
