This app demonstrates a few concepts..

• Rapid prototyping with Docker
• Kafka
• A simple producer (message-api)
• A simple consumer (consumer) that does something with the messages (stores them in redis)
• A simple www-api that reads from redis and returns this data via JSON
• A simple web page (using harp to serve the static assets) which uses jquery to display a list of messages from the www-api
• Running of Integration tests

This is not meant to ever leave a developers laptop...

Checkout this repo and just run docker-compose up -d.

Fire off an event with something like....

curl -X POST -H "Content-Type: application/json" -d '{"message":"This is a test message!"}' http://192.168.99.100:8081/message/news

Tail the logs of the consumer process

curl 192.168.99.100:8080/messages/list

open http://192.168.99.100:9000

1. First start all services via docker-compose up -d
2. Give the system a minute or so to converge and such. Kafka needs to start up and register itself with zookeeper.
3. Run the integration tests with the following command docker-compose run tests lettuce
