Defined in:
lib/vagrant-windows-domain/action/leave_domain.rb

Overview

Leave a domain on a ‘vagrant destroy`.

This is an Action middleware component that will detect the state of the machine - and any corresponding configuration and act accordingly. This function accepts user input and will halt the execution of proceeding middleware if the user chooses to cancel.

Also note that it will interfere with a ‘vagrant destroy` user input to avoid duplicate “are you sure..” messages.
