LCOW enabled system can't run Windows containers #35303
Description
Description
When running an LCOW enabled dockerd on Windows Server 1709 with $env:LCOW_SUPPORTED=1
and $env:LCOW_API_PLATFORM_IF_OMITTED="linux" set, Linux containers can be started but Windows containers such as nanoserver won't start.
Steps to reproduce the issue:
- Setup LCOW/LinuxKit as per https://blog.docker.com/2017/09/preview-linux-containers-on-windows/ and https://gist.github.com/rn/6bfade1ba98e22691cb287cc8c23609b
.\dockerd.exe -D --experimental -H 0.0.0.0:12375 --data-root "C:\lcow"docker run -H localhost:12375 -it microsoft/nanoserver powershell
Describe the results you received:
CLI output
cannot download image with operating system "windows" when requesting "linux".
See 'C:\LabBits\tools\docker.exe run --help'.

Ability to run both Linux and Windows containers alongside of each other without making specific changes.

Additional environment details (AWS, VirtualBox, physical, etc.):
