Karafka Example

A dockerized example on how to use Apache Kafka message broker with Ruby Karafka gem to publish/subscribe events between systems.

Usage

  1. Start the docker container by executing the below in the terminal (you need to install docker if not installed)

docker-compose up --build

Now Apache Kafka and Zookeeper are up and running, also our example-app is running Karafka server.

  1. Attach shell to the container example-app_app01 and send some messages by executing the following:

rake waterdrop:send

This will execute a rake task in the example code which publish some messages using waterdrop gem.

  1. Now you should see logs indicates that the karafka server consumed the messages and a ping pong messaging is working.

Please note that the example used here is the same official example provided by Karafka, I made this repo to make it easy to get things (kafka, zookeeper, karafka server) up and running quickly so anybody can play with the example smoothly to get a simple POC of what we can acieve with kafka.

Also you can implement your local message producers/consumers and use the kafka instance running in this example on kafka://localhost:9092
