Docker host network container service access under Windows

If I run docker container using the host network (--network host), for any services running in the container their exposed port can be directly accessed from host right?

I always thought so until I'm running docker container using the host network under Windows --

I.e., the container IP address and host IP are completely different. Unlike what the https://www.metricfire.com/blog/understanding-dockers-net-host-option/ says.

Anyway, if I'm running any services in the container, how to expose their port so that they can be directly accessed from host? (I thought with host network (--network host), you no longer need to map port from container to host)

thx

Since version 4.34 Docker Desktop for Windows supports host networking. https://docs.docker.com/engine/network/drivers/host/

Host networking is not supported on Windows:

The host networking driver only works on Linux hosts, and is not supported on Docker Desktop for Mac, Docker Desktop for Windows, or Docker EE for Windows Server.

https://docs.docker.com/network/network-tutorial-host/

I would suggest trying the -p option to docker run, since that is supported on Windows.

Alternately, one forum user suggests using VirtualBox in bridged mode to install Linux, which can then use host networking. YMMV.
