# Tested on Docker Toolbox installed via Homebrew

# Create a VirtualBox machine named as "default"
docker-machine create -d virtualbox --virtualbox-memory 2048 --virtualbox-disk-size 204800 default
# Start the Machine
docker-machine start default
#GET ENV
docker-machine env --shell=bash default
#Echo Env onto the terminal session
eval "$(docker-machine env --shell=bash default)"
# Explore the virtual machine with SSH
      #docker-machine ssh default
      ## Make Necessary Changes -- and then exit ssh example:
      # vi /etc/sysctl.conf
      # Save the machine state for the sake of later use
VBoxManage controlvm default savestate
# Restart the virtual machine "default", set env
docker-machine restart && eval "$(docker-machine env default)"
#To Confirm that changes are persistant, browse the machine to view if changes are saved
#docker-machine ssh default
# Clean up the virtual machine "default"
#docker-machine rm -f default
#rm -rf ~/.docker/machine/machines/default
