I am using 3 docker images for zookeeper , Kafka and Kafka Manager by dockerkafka ,

config :kaffe,
  producer: [
    endpoints: [kafkadocker_kafka_1: 9092],
    allow_topic_auto_creation: true,
    # endpoints references [hostname: port]. Kafka is configured to run on port 9092.
    # In this example, the hostname is localhost because we've started the Kafka server
    # straight from our machine. However, if the server is dockerized, the hostname will
    # be called whatever is specified by that container (usually "kafka")
    topics: ["test_topic"], # add a list of topics you plan to produce messages to
  ]

Above is the config in config.exs ,

I tried both with localhost and the container name after mapping the port 9092 , during the container startup ,

Command I am using to being up the containers ,

docker run -d --name kafkadocker_zookeeper_1  dockerkafka/zookeeper;docker run -d -p 9092:9092 --name kafkadocker_kafka_1 --link kafkadocker_zookeeper_1:zookeeper dockerkafka/kafka;docker run -it --rm --name kafka-Manager --link kafkadocker_zookeeper_1:zookeeper --link kafkadocker_kafka_1:kafka -p 9000:9000 -e ZK_HOSTS=zookeeper:2181 dockerkafka/kafka-manager

It doesnt work and fails at the startup while connecting to the broker , does anyone know what could be the case here ?
