I really like what this script is doing - it's specifying system level dependencies, a database schema, an interpreter, the code that runs on that interpreter, the data (on disk!) required by that code, and an invocation to execute the code all in one script. That's amazing, and this is an excellent model for sharing a stand alone applications with non-trivial dependencies!

However, Docker is an OS-level virtualization. Docker natively supports Windows in the sense that there is a native app. That native app spins up Linux virtual machines, so the container is "native" to my Intel CPU with their virtualization extensions, but it is not native to Windows. I use it, which I say with no animus toward your original message.

edit: I was ignorant of native windows containers. I'm old and my brain still maps docker to lxc I guess. Apologies to OP - the DirectX line should have caught my attention.
