我的 docker-compose 是运行，但我无法从主机访问

Question

这是我的 docker-compose.yml 文件

version: '3.2'

  zookeeper:

    depends_on:

      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，我也无法在容器内生成任何消息。这里有什么问题？如果我能建立连接，这条消息会通过 logstash 发送吗？

Answer 1

KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://localhost:9092

如果您只通告本地主机，Docker 网络中的 Kafka 客户端将无法访问您的代理。

此外，我不确定 Strimzi 图像是否使用了这些变量 - source

您可以使用所讨论的 confluentinc/cp-kafka 图像 in this post 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，它们都有自己的容器这些设置的各个环境变量
