All the configurations we have done up until this point have relied on using the docker0 bridge to facilitate connectivity between containers. We've had to consider port mappings, NATing, and container connection points. These considerations had to be made because of the nature of how we connect and address containers and to ensure a flexible deployment model. Host mode takes a different approach and binds containers directly to the Docker host's interfaces. This not only removes the need for inbound and outbound NAT but also restricts how we can deploy containers. Since the containers will be in the same network construct as the physical host, we cannot overlap service ports as this would cause a conflict. In this recipe, we'll walk through deploying a container in host mode and describe the pros and cons of this approach.

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.
