Specify headless or GUI from command-line

According to the documentation it's easy to run a Vagrant VM in GUI mode:

config.vm.provider "virtualbox" do |v|
  v.gui = true
end

However, is there a way to do this from the command-line, for example when running vagrant up? For example,

vagrant up --gui
vagrant up --headless

Different users may prefer to boot the UI or not; it doesn't seem like it should be specified in the Vagrantfile that everyone will use!

The GUI option is provider specific (and only very few providers support it), so it doesn't feel right for a top level vagrant command to add a switch for it.

To my experience the most common use cases for GUI are:

  • Running a desktop type machine, in which case the setting makes sense in the Vagrantfile
  • Debugging a boot etc. issue, when you just want to enable it for a moment

If you anyway have a setup where it's normal to switch the GUI on and off, you can use environment variables. For example something like this in Vagrantfile:

# Returns true if `GUI` environment variable is set to a non-empty value.
# Defaults to false
def gui_enabled?
  !ENV.fetch('GUI', '').empty?
end

Vagrant.configure('2') do |config|
  config.vm.provider 'virtualbox' do |v|
    v.gui = gui_enabled?
  end
end

Then on command line on a *nix system:

GUI=1 vagrant up

And on Windows:

set GUI=1
vagrant up
