This is a Vagrant test environment to run Docker Desktop in a VMware Fusion vagrant box. You need a Windows 10 Vagrant box, eg. built with https://github.com/StefanScherer/packer-windows and VMware Fusion 11.0.1 and Vagrant 2.2.x. Or maybe one of the boxes at Altas https://atlas.hashicorp.com/boxes/search?utf8=✓&sort=&provider=&q=win10 may help you skip the packer build step.
vagrant plugin install vagrant-reload
vagrant up
To start Docker Desktop wait until the desktop icon appears. Then double-click it.
You can switch between the Linux and Windows containers.
