What about the negatives?

Docker has lots of potential, but sadly it doesn't always live up to people's hopes and aspirations. Microsoft now has native support for Docker containers, but we never did see that much hope for an Internet Explorer container. If you still need to test in Internet Explorer, sadly it's still administering physical boxes or your own set of virtual machines. On the plus side of things, Internet Explorer is becoming less and less relevant, so hopefully we will never need them. What about Edge though? It would be nice to be able to spin up some Edge containers in Docker to get away from physical Windows machines, or virtual machines for Edge testing. Alas, that doesn't appear to be coming any time soon. Windows Docker containers don't support a Windows GUI at the moment and there probably aren't that many use cases where doing...
