Short answer, yes. Medium answer, images your Dockerfile is based on are still run in a Linux environment, even if it's virtualised differently.

Wait now, hold on a minute. I'm very confused and curious how does this work? Can I run any linux-based container on Windows? Can I run (are there any?) windows-based containers? If so, does it work the other way around: windows container on linux host? Does it somehow use the recently published Linux Subsystem for Windows, or is it completely different compatibility layer? If it is different, doesn't it seem like a waste of effort?

      No, GP got it right. The quoted part is that instead of VirtualBox one can use Hyper-V. In either case, it's handled by docker-machine which runs a GNU/Linux VM with Docker (host) tools installed, and containers are ran on that VM. I would be surprised if there aren't plans to support WSL (to run Linux-targetting binaries on Windows "natively", thus have "native" Docker containers) but don't think that's available yet.

  Native Windows containers are in beta and will be released later this year. You cannot run them on Linux hosts. They do not use the Windows subsystem for Linux, they are really native for Windows.
