I have got a dockerfile based on the full-fat windows,
ie my first line is -
I then install lots of stuff including an app that requires full windows rather than servercore, nanoserver or iotcore.
Now I want to add python 2.7 to my container.
I struggled doing it manually then I tried adding a second FROM command.
But now I fear that my final image is based on Windows Server 2016 rather than Windows.
Also do I need to use the COPY command to copy stuff from one layer to the other?
I think I could just look at the python dockerfile
and copy it into my dockerfile apart from its first line
Is there a recommended approach?
