By default, Docker performs most of the netfilter configuration for you. It takes care of things such as publishing ports and outbound masquerading, as well as allows you to block or allow ICC. However, this is all optional and you can tell Docker not to modify or add to any of your existing iptables
rules. If you do this, you'll need to generate your own rules to provide similar functionality. This may be appealing to you if you're already using iptables
rules extensively and don't want Docker to automatically make changes to your configuration. In this recipe we'll discuss how to disable automatic iptables
rule generation for Docker and show you how to manually create similar rules.

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.
