问题
I set up Docker for Windows on my laptop and switched from Linux Containers to Windows Containers in Docker's settings (which prompted a couple of restarts and Windows updates). I pulled an image and ran a container based on it using the commands:
docker pull microsoft/dotnet-framework
docker run -it microsoft/dotnet-framework cmd
In a second terminal window, I executed the command:
docker cp app container_id:/
and received this error message:
Error response from daemon: filesystem operations against a running Hyper-V container are not supported
I googled this error, but nothing (explanatory) came up, quite surprisingly. Is there a way I can run the image as a Windows container rather than a Hyper-V container, on Windows 10?
Ultimately, I will deploy this container to a Windows Server 2016 host, but I need to do all development and testing in my laptop running Windows 10 Pro.

回答1:
Based on a comment by @GregorySuvalian, I understand that Windows 10 allows Hyper-V runtime only. So my workaround is to stop the container, running the docker cp command and restart the container. (I preferred this over setting up a volume, since it is just a one time operation.)
