NOTE: THIS HEADLINE DOES NOT MEAN THAT DOCKER WORKS IN WINDOWS
I have spent all day today trying to switch from running Docker in a Vagrant to running Docker for windows and can say without question that Docker and Windows are incompatible as of today.
Specific issues are numerous, but primarily it is slow, and has stupid defaults, volumes will drive you nuts, don't use with cygwin or Ubuntu for Windows either (volumes won't work) and expect everything to crash your terminals.
