Yesterday I told about moving the exisitng default boot2docker machine to my secondary hard drive.
Today, I wanted to create a new docker virtual machine directly to a specific location.
docker-machine -s "D:\softwares\Docker Toolbox\docker-vm" create --driver virtualbox machineName
Set as default location
Finally, I want to always use this new location so as mentionned here I created the variable environnement MACHINE_STORAGE_PATH with the path = D:\softwares\Docker Toolbox\docker-vm
