【问题描述】：

当我使用 http 协议 kafka 与我一起运行时，我遇到了 kafka 问题

但是在将协议从 http 升级到 https 之后

升级后所有服务都返回相同的错误

2021-10-28 23:16:26.367  WARN 1 --- [ad | producer-1] org.apache.kafka.clients.NetworkClient   : [Producer clientId=producer-1] Connection to node 1 (/206.189.178.228:9092) could not be established. Broker may not be available.
2021-10-28 23:18:02.623  WARN 1 --- [ntainer#1-0-C-1] org.apache.kafka.clients.NetworkClient   : [Consumer clientId=consumer-2, groupId=groupId] Connection to node 1 (/206.189.178.228:9092) could not be established. Broker may not be available.

在生产者和消费者中，我不知道会发生什么，也不知道这个错误是否来自 SSL

但我没有更改任何关于 Kafka 的配置

这是我的 kafak.yml 文件

                                                                                   kafka.yml

networks:

这是服务配置，此配置存在于其他服务中

【解决方案1】：

Kafka 不是 HTTP 协议，因此您的问题与此无关

你已经设置了KAFKA_BOOTSTRAPSERVERS=kafka:9092

我没有更改任何关于 Kafka 的配置

我想你做到了。该 IP 地址不是任何默认值。要在同一 Docker 网络中恢复到预期行为，您需要设置

LISTENERS: PLAINTEXT://0.0.0.0:9092
KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://kafka:9092

不清楚您从哪里获取 IP 地址，但如果您想将 Docker 容器暴露给该子网中的外部网络，那么您将需要其他设置
