Full Description

Kafka in Docker

This repository provides everything you need to run Kafka in Docker.

For convenience also contains a packaged proxy that can be used to get data from
a legacy Kafka 7 cluster into a dockerized Kafka 8.


The main hurdle of running Kafka in Docker is that it depends on Zookeeper.
Compared to other Kafka docker images, this one runs both Zookeeper and Kafka
in the same container. This means:

  • No dependency on an external Zookeeper host, or linking to another container
  • Zookeeper and Kafka are configured to work together out of the box


Extract your docker-machine IP or use your localhost IP (with latest Docker CE 17.04):

docker run -p 2181:2181 -p 9092:9092 -p 9093:9093 -p 9094:9094 --env ADVERTISED_HOST= --env ADVERTISED_PORT=9092 hkarhani/kafka3 
export KAFKA=`docker-machine ip \`docker-machine active\``:9092 --broker-list $KAFKA --topic test
export ZOOKEEPER=`docker-machine ip \`docker-machine active\``:2181 --zookeeper $ZOOKEEPER --topic test

Running the proxy

Take the same parameters as the spotify/kafka image with some new ones:

  • CONSUMER_THREADS - the number of threads to consume the source kafka 7 with
  • TOPICS - whitelist of topics to mirror
  • ZK_CONNECT - the zookeeper connect string of the source kafka 7
  • GROUP_ID - the to use when consuming from kafka 7
docker run -p 2181:2181 -p 9092:9092 \
    --env ADVERTISED_HOST=`boot2docker ip` \
    --env ADVERTISED_PORT=9092 \
    --env CONSUMER_THREADS=1 \
    --env TOPICS=my-topic,some-other-topic \
    --env ZK_CONNECT=kafka7zookeeper:2181/root/path \
    --env GROUP_ID=mymirror \

In the box

  • spotify/kafka3

    The docker image with 3x Kafka Brokers and a Zookeeper. Built from the kafka3

  • spotify/kafkaproxy

    The docker image with Kafka, Zookeeper and a Kafka 7 proxy that can be
    configured with a set of topics to mirror.
