Run Kafka Container

Start Kafka service

The following commands will start a container with Kafka and Zookeeper running on mapped ports 2181 (Zookeeper) and 9092 (Kafka).

docker pull spotify/kafka
docker run -d -p 2181:2181 -p 9092:9092 --env ADVERTISED_HOST=kafka --env ADVERTISED_PORT=9092 --name kafka spotify/kafka

Why Spotify?

ADVERTISTED_HOST was set to kafka, which will allow other containers to be able to run Producers and Consumers.
