Docker Container Networking

Each container should serve a single purpose, such as running one application like a web server. Containers can be powerful by themselves, but when connected together, they are far more useful. For example, a web server container can be connected to a database container to provide application storage. Docker provides multiple options for networking containers. In this lab, you'll explore a few of the common types of networks that Docker supports, and learn how containers within those networks interact.
