Run updates on your Pantheon site on a separate multi-dev environment. If any updates found -- also runs visual regression testing using https://diffy.website service.
Borrowed a lot of code from https://github.com/pantheon-systems/example-terminus-auto-update-script
Script does:
- checks if your site needs updates
- drops and recreate auto-updates multidev environment
- deploy all the updates there
- trigger Diffy compare job to verify against Live
In order to set it up check configuration.sh script for required variables.
Also set up a project in Diffy for the Live environment of the site.
