Kafka in Docker not working

My solution to this issue is slightly different. I configure Kafka to advertise on kafka host and, because it’s exposed on the host machine on localhost:9092, I add an entry in /etc/hosts for kafka to resolve to localhost. By doing this Kafka can be accessed from both other Docker containers and from localhost.

docker-compose.yml:

  my-web-service:
    build: ./my-web-service
    ports:
     - "8000:8000"
    links:
     - kafka
  kafka:
    image: "wurstmeister/kafka:0.10.2.0"
    ports:
     - "9092:9092"
    hostname: kafka
    links: 
     - zookeeper
    environment:
     - KAFKA_ADVERTISED_HOST_NAME=kafka
     - KAFKA_ZOOKEEPER_CONNECT=zookeeper:2181
     - KAFKA_ADVERTISED_PORT=9092
  zookeeper:
    image: wurstmeister/zookeeper
    ports:
      - "2181:2181"

Updated hosts file:

more /etc/hosts
127.0.0.1       localhost kafka
