如何为Kafka本地开发配置docker-compose.yml?

我正在尝试在docker容器中设置Kafka以进行本地开发。我的docker-compose.yml如下所示:

version: '3'
services:
  zookeeper:
    image: wurstmeister/zookeeper
    ports:
      - "2181"
    hostname: zookeeper
  kafka:
    image: wurstmeister/kafka
    command: [start-kafka.sh]
    ports:
      - "9092"
    hostname: kafka
    environment:
      KAFKA_CREATE_TOPICS: "UploadFile:1:1,GetFile:1:1,TrackUpload:1:1,GetEmailContent:1:1" # topic:partition:replicas
      KAFKA_ADVERTISED_HOST_NAME: kafka # docker-machine ip
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
      KAFKA_ADVERTISED_PORT: 9092
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    depends_on:
      - "zookeeper"

不幸的是,我在本地主机(不在docker中)运行的节点应用无法连接到它。我使用了网址“ kafka:9092”,甚至是“ localhost:9092”。什么都没有。知道发生了什么事吗?

暴露用于kafka服务的主机端口9092,您应该能够从应用程序或主机通过“ localhost:9092”进行连接。

  ....
  kafka:
    image: wurstmeister/kafka
    command: [start-kafka.sh]
    ports:
      - "9092:9092"
  ....
