我正在尝试使用docker容器设置单个Kafka代理，我正在使用来自的图像。目标是在docker中运行Kafka代理，并从主机运行生产者/消费者

在配置

KAFKA_监听器

和

KAFKA_监听器

属性时，我意识到如果以下配置已就位，我将无法检索代理元数据

KAFKA_BROKER_ID: 0
KAFKA_INTER_BROKER_LISTENER_NAME: INTERNAL

KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
KAFKA_AUTO_CREATE_TOPICS_ENABLE: 'false'
KAFKA_MESSAGE_MAX_BYTES: '200000'

但是将

EXTERNAL://localhost:9092

替换为

EXTERNAL://kafka0:9092

或

EXTERNAL://:9092

（默认界面）中的

KAFKA\u侦听器

config可以修复它。

>kafkacat -b localhost:9092 -L
Metadata for all topics (from broker 0: localhost:9092/0):

这是非常令人费解的。卡夫卡2.2.x的卡夫卡文档中没有任何关于这种行为的内容。希望有人能给我们一些启示

对于

侦听器

（不是公布的侦听器）

默认值为

0.0.0.0

，这意味着监听所有接口

通过将其设置为本地主机名，它只在本地（容器内）公开，而不向您的主机公开

，但我不明白这会如何影响

KAFKA_播发的_侦听器

设置。是不是当我尝试连接到localhost:9092时，它将尝试查找绑定在kafka0:9092的侦听器？您不是“外部”常规侦听器，因为设置已经是这样工作的。。。你只需要一个广告上的。如果您连接到端口9092，那么它仍然会响应localhost:9092，但这解释了当我尝试使用

kafkacat-b localhost:9092-L

连接到localhost:9092时，我从

KAFKA\u播发的侦听器

上接收元数据的是

EXTERNAL://localhost:9092

侦听器。但是，在

KAFKA_LISTENER

上使用相同的配置如何防止这种情况发生？正如我所解释的，它只侦听内部docker接口，而不侦听外部接口，因此端口转发甚至不起作用。你可以在融合的示例中看到，我现在看到的普通侦听器甚至都没有设置。谢谢
