Hi Rachel - thanks for this! Saved me a lot of time tonight. :)

A couple of notes:

• Drupal will fail to do config-import with this setup, because the image is missing the sqlite3 client. Easy to fix by adding apt install -y sqlite3 anywhere before that step.
• This doesn't do any caching. You very likely want to restore cache right before "composer install", with

     - restore_cache:
                key: deps1-{{ .Branch }}-{{ checksum "working/composer.lock" }}

And save it right after composer install, with:

     - save_cache:
          key: deps1-{{ .Branch }}-{{ checksum "~/working/composer.lock" }}
          paths:
            - "~/working/vendor"
            - "~/working/web/core"
            - "~/working/web/modules/contrib"
            - "~/working/web/profiles/contrib"
            - "~/working/web/themes/contrib"
            - "~/working/drush/contrib"
            - "~/working/libraries"
            - "~/.composer"

You could probably even get clever and cache an sqlite database of a fresh "minimal" install, and use drush cim instead of si.

Anyway thank you!

Since around beginning of Feb 2018 you have to update /etc/hosts manually to have Behat resolve the URL:

      - run:
          name: Update host file
          command: |
            echo 127.0.0.1 example.localhost | sudo tee -a /etc/hosts
            cat /etc/hosts

Otherwise you'll get cURL error 6: Could not resolve host: example.localhost.
