Kafka (and Zookeeper) in Docker

Kafka in Docker

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

Why?

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

Run

Any kafka property can be set by using an env variable prefixed by _KAFKA_. All the . in the property name have to be replaced by _ (bash env variables can not contain .)

docker run -p 2181:2181 -p 9092:9092 --env _KAFKA_advertised_host_name=`docker-machine ip \`docker-machine active\`` --env _KAFKA_advertised_port=9092 flozano/kafka

export KAFKA=`docker-machine ip \`docker-machine active\``:9092
kafka-console-producer.sh --broker-list $KAFKA --topic test

export ZOOKEEPER=`docker-machine ip \`docker-machine active\``:2181
kafka-console-consumer.sh --zookeeper $ZOOKEEPER --topic test
