我的 docker-compose 正在运行，但我无法从主机访问

Question

这是我的 docker-compose.yml 文件

version: '3.2'

services:
  elasticsearch:
    build:
      context: elasticsearch/
      args:
        ELK_VERSION: $ELK_VERSION

  zookeeper:
    image: strimzi/kafka:0.11.3-kafka-2.1.0
    container_name: zookeeper

    ports:

    networks:

  kafka:
    image: strimzi/kafka:0.11.3-kafka-2.1.0
    command: [
      "sh", "-c",
      "bin/kafka-server-start.sh config/server.properties --override listeners=$${KAFKA_LISTENERS} --override advertised.listeners=$${KAFKA_ADVERTISED_LISTENERS} --override zookeeper.connect=$${KAFKA_ZOOKEEPER_CONNECT}"
    ]
    depends_on:
      - zookeeper
    ports:
      - "9092:9092"
    networks:
      - elk
    environment:

      KAFKA_LISTENERS: PLAINTEXT://0.0.0.0:9092
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181

networks:
  elk:
    driver: bridge

volumes:
  elasticsearch:

这是我的 logstash.conf 文件：

input {
  kafka {
    bootstrap_servers => "kafka:9092"
    topics => "results"
    codec => json { charset => "UTF-8" }
    }
}
filter {
    date {
    match => [ "timestamp" , "dd/MMM/yyyy:HH:mm:ss Z" ]
    }
}
output {
    elasticsearch {
        hosts => "elasticsearch:9200"
        user => "elastic"
        password => "changeme"
        ecs_compatibility => disabled
    }
}

我可以向结果主题发送消息，但我也无法在容器内看到此消息，也无法在容器内生成任何消息。这里有什么问题？如果我可以建立连接，这条消息无论如何都会通过logstash？

Answer 1

KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://localhost:9092

如果您只宣传 localhost，Docker 网络中的 Kafka 客户端无法访问您的代理。

另外，我不确定 Strimzi 图像是否使用了这些变量 - source

您可以使用confluentinc/cp-kafka 所讨论的confluentinc/cp-kafka 图像，对这些变量稍作修改，或者如果您对此有异议，您可以使用 Bitnami 或 wurstmeister 容器，它们每个都有自己的用于这些设置的单独环境变量
