Docker for Windows supports Host mode?

Docker is a containerization technology that can be implemented by packaging applications into containers, simplifying the process of application deployment, management and operation. Docker not only supports running on Linux operating systems, but also supports running on Windows operating systems, and the operation methods are very similar.

However, there are some differences between using Docker on the Windows platform and using Docker on the Linux platform. One of the main differences is: does Docker for Windows support Host mode?

On the Linux platform, Docker supports Host mode. The function of this is to run the container directly in the network namespace on the host, thereby achieving the effect of consistent network interfaces between the container and the host, reducing network Delay and performance loss caused by forwarding.

In Docker for Windows, due to the structure and characteristics of the Windows operating system, Docker does not support Host mode. The reason is:

1. The network structure of the Windows operating system is different from that of Linux, and the Windows version of Docker needs to run the Hyper-V virtual machine on Windows Server 2016 and later versions, which results in Docker for Windows There is no way to access network devices on the host like the Linux version of Docker.
2. In addition, in Docker for Windows, the network interface between the container and the host is provided by a virtual bridge (VirtualBridge). This virtual network bridge method does not support Host mode.

Therefore, regardless of whether you use the server version or the desktop version of Docker for Windows, you cannot use the Host mode.

Of course, in Docker for Windows, there are also some other network modes to choose from, such as Bridge mode, Overlay mode, Macvlan mode, etc. These modes can meet different needs, such as the interconnection between containers, the connection between containers and the host, etc.

Summary

Although Docker for Windows does not support the Host mode, on the Windows platform, other network modes can still be used to replace the Host mode, such as Bridge, Overlay and other modes. If you need to use container technology on the Windows platform, Docker for Windows can also provide a good containerization platform.
