docker - 套接字服务器无法绑定到 kafka:29092: 无法分配请求的地址

问题描述

我正在尝试从以下 yaml 文件创建一个 kafka 服务器：

version: "3.9"

services:
  zookeeper:
    image: 'bitnami/zookeeper:latest'
    ports:
      - '2181:2181'
    environment:
      - ALLOW_ANONYMOUS_LOGIN=yes

  kafka:
    image: 'bitnami/kafka:latest'
    ports:
      - '9092:9092'
    environment:
      - KAFKA_BROKER_ID=1
      - ALLOW_PLAINTEXT_LISTENER=yes
      - KAFKA_CFG_ZOOKEEPER_CONNECT=zookeeper:2181
      - KAFKA_LISTENERS=PLAINTEXT://kafka:29092,PLAINTEXT_HOST://localhost:9092
      - KAFKA_LISTENER_SECURITY_PROTOCOL_MAP=PLAINTEXT:PLAINTEXT,PLAINTEXT_HOST:PLAINTEXT
      - KAFKA_INTER_BROKER_LISTENER_NAME=PLAINTEXT
      - KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://kafka:29092,PLAINTEXT_HOST://localhost:9092
    depends_on:
      - zookeeper

但我收到一个错误：

我的配置有什么问题？

解决方案

错误在于绑定侦听器。 KAFKA_LISTENERS对于 bitnami 容器不正确。KAFKA_CFG如其自述文件中所写，所有代理属性都应以 开头。

此外，您应该设置KAFKA_CFG_LISTENERS使用 IP0.0.0.0来接受所有接口上的所有流量
