Switch to Windows Container needs to selected from docker icon running under hidden icon from the bottom right... The moment you switch from Linux to Windows or Windows to Linux, Docker daemon automatically restarts to consider switched container...

I would highly recommend you to view these 2 links to get more insight into how to create window containers:

• Forum post

• Blog post

I really found the content of these links very helpful to make a window container which is still being enhanced for the generic issue we are all are facing since support for window container is yet to mature like Linux containers!

Answer 2

You need to go to the Taskbar → right click the Docker icon → use option Switch to Windows containers...

Answer 3

Your Docker host is configured to run Linux containers inside of a VM. To run Windows containers, you need to "Switch to Windows containers" in the Docker menu. Documentation on that is available here.

Answer 4

microsoft/nanoserver is a windows native container image. So you cannot run this as linux containers run natively. It can only be run on windows 10 or windows server.

If you are in windows 10, you can switch to windows containers by selecting

switch to windows containers
