title: Kafka setup with docker-compose
body: <p>Hi I'm currently setting up Kafka with Docker. I've managed to setup Zookeeper and Kafka with the published confluent image, see following docker-compose file:</p>
  
  <pre><code>version: '2'
  
  services:
    zookeeper:
      image: confluentinc/cp-zookeeper:3.2.0
      container_name: zookeeper
      hostname: zookeeper
      ports:
        - "2181:2181"
      environment:
        ZOOKEEPER_CLIENT_PORT: 2181
        ZOOKEEPER_TICK_TIME: 2000
      restart: always
  
    kafka:

     restart: always
  
   connect:

     container_name: kafka-connect
     depends_on:
       - zookeeper

  <p>Now I've managed to expose correctly the Kafka container to my non-dockerized applications by correctly setting the advertised.listener property to PLAINTEXT://{DOCKER_MACHINE_IP}:9092, but as you can see I've also added other confluent applications to extend my Kafka setup (Kafka REST, Schema-Registry). These can no longer connect to my Kafka instance because of the advertised.listener property. </p>
  
  <p>I could change it to the correct container hostname --> PLAINTEXT://kafka:9092 but then I lose the ability to reach the kafka instance once again with my other apps. Is there any easy way to solve this issue?</p>
