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

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。

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
