那些遇到过的问题

使用“localhost”配置侦听器会导致无法检索有关代理的元数据

coo*_*kie 4 apache-kafka docker docker-compose

我正在尝试使用 docker 容器设置单个 Kafka 代理，并且我正在使用此处的图像。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_LISTENERS和KAFKA_ADVERTISED_LISTENERS属性时，我意识到如果以下配置到位，我将无法检索代理元数据

KAFKA_BROKER_ID: 0
KAFKA_INTER_BROKER_LISTENER_NAME: INTERNAL
KAFKA_LISTENER_SECURITY_PROTOCOL_MAP: INTERNAL:PLAINTEXT,EXTERNAL:PLAINTEXT
# KAFKA_ADVERTISED_LISTENERS must be EQUAL or SUBSET of KAFKA_LISTENERS
KAFKA_LISTENERS: INTERNAL://kafka0:29092, EXTERNAL://localhost:9092
# INTERNAL://kafka0:29092 is specified because of the KAFKA_INTER_BROKER_LISTENER_NAME configuration.
KAFKA_ADVERTISED_LISTENERS: INTERNAL://kafka0:29092, EXTERNAL://localhost:9092

> kafkacat -b localhost:9092 -L
ERROR: Failed to acquire metadata: Local: Broker transport failure

但是在配置中替换EXTERNAL://localhost:9092为EXTERNAL://kafka0:9092或EXTERNAL://:9092（默认接口）修复了它。KAFKA_LISTENERS

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

这是非常令人费解的。Kafka 2.2.x 的 Kafka 文档中没有任何关于这种行为的说明。http://kafka.apache.org/22/documentation.html#config。希望有人能有所启发。

完整的 docker-compose 文件如下
