Note: The Docker Image is available here.

Run docker-compose up --build using the docker-compose.yml found here.
In this setup, the API will listen for Kafka at address kafka:9092 (kafka being the name of the kafka container), but the API will need to be manually linked to Kafka's container using the --link flag.

The configuration file can be found at api/appsettings.json.
The new setup can be executed by docker-compose up --build using .../api as the current working directory.
