【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？

标签： docker apache-kafka docker-compose

【解决方案1】：

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

另外，您应该将KAFKA_CFG_LISTENERS 设置为使用IP 0.0.0.0 来接受所有接口上的所有流量

【解决方案2】：

不管怎样，这对我来说是正确的配置：

version: "3.9"

services:
  zookeeper:
    image: 'bitnami/zookeeper:latest'
    deploy:
      replicas: 1
    ports:
      - "2181:2181"
    environment:
      - ALLOW_ANONYMOUS_LOGIN=yes

  kafka:
    image: 'bitnami/kafka:latest'
    deploy:
      replicas: 1
    ports:
      - 9092:9092
    depends_on:
      - zookeeper
    environment:
      KAFKA_CFG_ZOOKEEPER_CONNECT: zookeeper:2181
      KAFKA_CFG_LISTENERS: INTERNAL://:9093,OUTSIDE://:9092
      KAFKA_CFG_ADVERTISED_LISTENERS: INTERNAL://kafka:9093,OUTSIDE://sub.domain.ltd:9092
      KAFKA_CFG_LISTENER_SECURITY_PROTOCOL_MAP: INTERNAL:PLAINTEXT,OUTSIDE:PLAINTEXT
      KAFKA_CFG_INTER_BROKER_LISTENER_NAME: INTERNAL
      ALLOW_PLAINTEXT_LISTENER: "yes"
