How to build your own Raspberry Pi Cluster

Raspberry Pi Dramble cluster - with a banana for scale

When I originally built the Raspberry Pi Dramble 6-node Pi cluster in 2014 (for testing Ansible with bare metal hardware on the cheap), I compiled all the code, notes, etc. into a GitHub repository. In 2015, I decided to take it a step further, and I started hosting www.pidramble.com on the cluster, in my basement office!

Every time I've shared the cluster with others during presentations or at events like DrupalCon, someone how it's built. While I do have almost all my notes and instructions for building the entire cluster on the Pi Dramble Wiki, a step-by-step visual guide is better. Therefore, I'm posting a series of videos, "Let's Build a Raspberry Pi Cluster", to my YouTube channel.

The first video goes over hardware parts and setup:

The second goes over microSD card setup and Raspbian OS configuration:

These videos will also serve as good background material for those attending my upcoming talks on Drupal 8 and the Raspberry Pi:

I'll post again once I've wrapped up the video series (it will likely be either 5 or 6 parts total). What do you think of the videos? Should I consider making more of this kind of video, or ditch the idea and stick to writing?
