More and more, we find ourselves working with Docker containers in the context of microservice architectures comprising multiple, loosely-coupled applications and services, and/or projects made up of two or more distinct apps running side-by-side talking to each other via APIs. As developers who work on these types of projects know all too well, setting up your local development environment to run multiple Docker applications at the same time can be a real hassle. Developing each app on its own is a breeze using Kool and Docker Compose. However, when you need to run multiple apps at the same time, configuring the routing and intercommunication between different containers can be challenging.
