In the previous recipe, we saw how to deploy our microservice in Marathon. We were able to deploy the geolocation microservice on Marathon, but it was not really useful because we haven't figured out how to talk to our microservice via its RESTful API. In this recipe, we will learn how to configure our application's service and host ports in Marathon to expose the RESTful APIs.
If you don't have your cluster up and running, bring it back up. Also make sure you have the geolocation application up and running in your cluster. You can verify that from the Marathon web interface.
