docker-compose up -d

If you're on MacOS set an environment variable like:

export DOCKER_KAFKA_HOST=$(ipconfig getifaddr en0)

that is afterwards used in docker-compose.yml to identify the KAFKA_ADVERTISED_HOST_NAME. Some similar workaround has to exist for Windows users. For linux I assume you can just set it to localhost if you're only running on Kafka node. See github.com/wurstmeister/kafka-docker/wiki/Connectivity.

Kafka will be served on localhost:9092

open /geostream/frontend/app/index.html and associated map.js will consume messages when they come in

can produce messages to a topic at localhost:8002/producer/<topicname>

can consume kafka messages through at localhost:8003/consumer/<topicname>
