Configuring CloudFlare with Drupal 8 to protect the Pi Dramble

In a prior post on the constraints of in-home website hosting, I mentioned one of the major hurdles to serving content quickly and reliably over a home Internet connection is the bandwidth you get from your ISP. I also mentioned one way to mitigate the risk of DoSing your own home Internet is to use a CDN and host images externally.

At this point, I have both of those things set up for www.pidramble.com (a Drupal 8 site hosted on a cluster of Raspberry Pis in my basement!), and I wanted to outline how I set up Drupal 8 and CloudFlare so almost all requests to www.pidramble.com are served through CloudFlare directly to the end user!

CloudFlare Configuration

Before anything else, you need a CloudFlare account; the free plan offers the minimal necessary features (though you should consider upgrading to a better plan if you have anything beyond the simplest use cases in mind!). Visit the CloudFlare Plans page and sign up for a Free account.

Highly-Available Infrastructure Provisioning and Configuration with Ansible

The following is an excerpt from Chapter 8 of Ansible for DevOps, a book on Ansible by Jeff Geerling. The example highlights Ansible's simplicity and flexibility by provisioning and configuring of a highly available web application infrastructure on a local Vagrant-managed cloud, DigitalOcean droplets, and Amazon Web Services EC2 instances, with one set of Ansible playbooks.

tl;dr Check out the code on GitHub, and buy the book to learn more about Ansible!
