Limiting the amount of surprises you get when developing a large-scale Drupal project is always a good thing. And to that end, Acquia's BLT (Build and Launch Tools) wisely chooses to leave Drupal VM alone when updating BLT itself. Updates to Drupal VM can and should be done independently of install profile and development and deployment tooling.
But this creates a conundrum: how do you upgrade Drupal VM within a project that uses BLT and has Drupal VM as one of it's composer dependencies? It's actually quite simple—and since I just did it for one of my projects, I thought I'd document the process here for future reference:
- In your project's root, require the newer version of Drupal VM:
composer require --dev geerlingguy/drupal-vm:~4.0
(in my case, I was updating from the latest 3.x release to 4.x). - Edit your
box/config.yml
file—it's best to either use BLT's currentconfig.yml
template as a guide for updating yours, or read through the Drupal VM release notes to find out what config variables need to be added, changed, or removed. - Commit the updates to your code repository.
- (If updating major versions) Instruct all developers to run
vagrant destroy -f
, thenvagrant up
to rebuild their local environments fresh, on the new version. (If updating minor versions) Instruct all developers to runvagrant provision
to update their environments.
There are a lot of great new features in Drupal VM 4, like the ability to switch PHP versions in the VM on-the-fly. This is great for those testing migrations from PHP 5.6 to 7.0 or even 7.1! There's never been an easier and quicker way to update your projects to the latest VM version.
