In the previous recipe, we covered how Docker handles iptables
rules for the most common container networking needs. However, there may be cases where you wish to extend the default iptables
configuration to either allow more access or limit the scope of connectivity. In this recipe, we'll walk through a couple of examples of how to implement custom iptables
rules. We'll focus on limiting the scope of sources connecting to services running on your containers as well as allowing the Docker host itself to connect to those services.

Overview of this book
Networking functionality in Docker has changed considerably since its first release, evolving to offer a rich set of built-in networking features, as well as an extensible plugin model allowing for a wide variety of networking functionality. This book explores Docker networking capabilities from end to end. Begin by examining the building blocks used by Docker to implement fundamental containing networking before learning how to consume built-in networking constructs as well as custom networks you create on your own. Next, explore common third-party networking plugins, including detailed information on how these plugins inter-operate with the Docker engine. Consider available options for securing container networks, as well as a process for troubleshooting container connectivity.
Finally, examine advanced Docker networking functions and their relevant use cases, tying together everything you need to succeed with your own projects.
