Docker is awesome, right? And thanks to boot2docker Windows users were no longer left out of the fun. Still, setting everything up could be a PITA and you had to install Oracle VirtualBox to use it as Docker containers were actually run inside of a VM (which was the purpose of boot2docker).
This short post is more of a note to myself for when I run into the same problem. I just wasted an hour on it so I guess that justifies it. So, what happened? I wanted to check out the new Docker Machine with Hyper-V support, but the Hyper-V Manager told me it could not connect to my local computer.
