Is it possible to require certain Vagrant and VirtualBox versions in Vagrantfile?

Question

I recently noticed that I managed to have a version of Vagrant and VirtualBox installed that did not work with my Vagrantfile. Upgrading to the latest Vagrant & VirtualBox fixed the problem.

Is it possible to ensure minimum Vagrant and VirtualBox versions are installed before allowing vagrant up to launch?

Answer 1

For Vagrant itself, there is built-in support:

Vagrant.require_version ">= 1.3.5"

For Virtualbox, you can run some code at the top of your Vagrantfile like this:

if Gem::Version.new(`VBoxManage --version`.strip) < 
Gem::Version.new('5.1.6')
  abort "Please upgrade Virtualbox to 5.1.6 or later!"
end
