deciding most appropriate path for windows compatibility for cwltool and schema-salad

Hi As I would be working on windows compatibility, I need some help 😃
Current understanding according to me:

1. Some of our CommandLineTool uses baseCommand like echo and cat. These are unix tools only available in linux system.
2. We can run Linux container on a windows 10 machine. https://stefanscherer.github.io/run-linux-and-windows-containers-on-windows-10/
3. Docker support for windows server is only from windows server 2016 onwards. https://blog.docker.com/2016/09/dockerforws2016/

For us providing windows support means, a user can develop a workflow on his windows machine. On run if the workflow uses unix utilities/tools, then in that case these workflow should run in a Linux docker container or alternatively we can make it default that all workflows should run in a Linux container. We will be using Appveyor CI for testing and as some of our unit tests uses unix tools like cat on testing, I guess we need to provide a Linux container where they can use these tools. Appveyor has a Visual Studio 2017 image(runs windows server 2016) and supports docker But as I read somewhere this Docker support only applies to windows containers and not Linux Containers. I raised a issue with appveyor to confirm it.
I also found a Linuxkit for windows released last month that should allow linux container on windows server 2016 but I am not sure if Appveyor already supports it or not.
So if you have any idea how else we can test these builds, that would be awesome.
In the meantime what I am can do is, setup docker and linux container on my windows machine. Start working on other issues that are preventing us from windows support and for running test cases, use --default-container flag to generate a linux container and run test cases there. I talked to Janneke, she is one of my mentor and potential user of windows support and for her use case running workflows in a linux container on windows machine is good.

Thanks to all for helping. 😄 Now cwltool and Schema salad is Windows Compatible.

So maybe they are doing it on purpose. For Now I will start working with Schema-salad for windows compatibility.
