As a way to get Zookeeper / Kafka AND Kafka Manager working together in docker compose...

docker-compose.yml

version: '2'
services:
  zookeeper:
    hostname: zookeeper
    image: wurstmeister/zookeeper
    ports:
      - "2181:2181"
  kafka:
    hostname: kafka
    image: wurstmeister/kafka:0.9.0.0-1
    ports:
      - "9092:9092"
      - "9093:9093"
    links:
      - zookeeper
    environment:
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
      KAFKA_ADVERTISED_HOST_NAME: ${DOCKER_KAFKA_HOST}
      JMX_PORT: 9093
      KAFKA_ADVERTISED_PORT: 9092
      KAFKA_DELETE_TOPIC_ENABLE: 'true'
      KAFKA_LOG_RETENTION_HOURS: 1
      KAFKA_MESSAGE_MAX_BYTES: 10000000
      KAFKA_REPLICA_FETCH_MAX_BYTES: 10000000
      KAFKA_GROUP_MAX_SESSION_TIMEOUT_MS: 60000
      KAFKA_NUM_PARTITIONS: 2
      KAFKA_DELETE_RETENTION_MS: 1000
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
  kafka-manager:
    hostname: kafka-manager
    image: sheepkiller/kafka-manager
    ports:
      - "9000:9000"
    links:
      - zookeeper
      - kafka
    environment:
      ZK_HOSTS: zookeeper:2181
      APPLICATION_SECRET: letmein  

You need to also do:

export DOCKER_KAFKA_HOST=$(ipconfig getifaddr en0)

This is how to get it working on Mac!

For working with postgres in a container:

docker run -e POSTGRES_USER=dev -e POSTGRES_PASSWORD=secret -p 5432:5432  postgres
