Setting Up A Drupal 8 Container on CircleCI with CircleCI 2.0 Syntax

I recently went through a learning process I want to share, since I found it somewhat difficult to find the pieces to make this work. That is, having CircleCI 2.0 style testing run on a Drupal 8 installation. For the environment setup, I wanted to use PHP 7.1, and MySQL 5.7. I also knew that I wanted to get drush working, and therefore would need composer, and I wanted to be able to leverage drush as I started this initial test environment. For this first run, I also wanted to execute a PHPUnit test 'FilterQualtricsTest' from our custom utexas_qualtrics_filter module. Here's how I wound up getting it setup.

NOTE: We are using a /web folder for our docroot, and composer with some defined composer-types that install into our web/ directory. If you aren't using this kind of structure, you should modify the code accordingly.

In the root of the project, have a .circleci folder with the following file structure:

Here's the code for these files. You may not necessarily need ALL the commands I'm using, and as I mentioned above, you may need to tweak the /web path depending on your Drupal site configuration. But it should serve as a great starting point for lots of different setups.

Listen 8080

<VirtualHost *:8080>

  UseCanonicalName Off
  ServerName test.dev
  DocumentRoot home/circleci/site_build/web

  <Directory "home/circleci/site_build/web">
    Options FollowSymLinks

Now when CircleCI tests your site, you should see all the steps execute, and get that nice, satisfying:
