Yeah. Long time without writing here. I have lost about 2 or 3 hours of my life trying to configure it. So I think it deserves a post so anyone googling can find it.
It is as simple as adding the following to your
drush: install: '1' version: '8.x'
Yes. That's right. PuPHPet supports Drush already (I think because Puppet does.) Make sure you are already using
composer, otherwise it won't work.
