if you are developing a regular web application, please use -p or it's better to look into user defined networks, docker-compose, and Swarm or Kubernetes, so that you build your app with the end in mind.You can read more about the topic on the Docker forums here and here. If you are wondering wether Docker will implement this on the Mac and Windows follow this issue. The reason behind this is that the Docker for Mac and Windows applications use a virtual machine under the hood, and "host" means the VM in this case, not your host machine. You can start your containers with -network host on the Mac without an error, but you'll not get the results you'd expect.
The host networking driver only works on Linux hosts, and is not supported on Docker for Mac, Docker for Windows, or Docker EE for Windows Server. It's mentioned here in the official docs.

The host network driver will work on Linux the way you'd expect, but it will not give you what you are looking for on Mac and Windows.
