What's this got to do with DevOps?

Among other things, DevOps is about:

• Culture of collaboration
• Infrastructure as code
• Automating all the things
• Continuous Deployment

Why 'Fearless'?

Why 'Fearless'?

Setting up a proper development environment is:

• difficult
• time-consuming
• un(der)-appreciated

Why 'Fearless'?

"... the three great virtues of a programmer:

laziness, impatience, and hubris."

-- Larry Wall, et. al.

Programming Perl, 2nd Ed.

Why 'Fearless'?

Setting up a dev env is:

• difficult
• time-consuming
• un(der)-appreciated

Tools that can help

• Drush + Vagrant = Drush Vagrant Integration
• Drush-vagrant + Aegir = Aegir-up

What is Drush?

• Command line shell and Unix scripting interface for Drupal
• Common and widely supported Drupal power tool
• Written in PHP
• Drupal-specific

What is Vagrant?

• Command line shell and Unix scripting interface for VirtualBox
• Increasingly popular in DevOps circles
• Written in Ruby

What is Drush-Vagrant?

• A Drush extension that provides aliases and useful commands around Vagrant
• Written in PHP (mostly)
• Not exclusively Drupal-specific

What is Aegir?

• Drush & Drupal
• Aegir makes it easy to install, upgrade, deploy, and backup an entire network of Drupal sites
• Written in PHP (mostly)

What is Aegir-up?

• Aegir-up is a Drush-vagrant blueprint
• Local Aegir VM
• Written in PHP & Puppet

Why Fearless?

DevOps is about:

• Culture of collaboration
• Infrastructure as code
• Automating all the things
• Continuous Deployment

Why Fearless?

• Rebuild your entire environment quickly and easily
• Avoid 'works in dev, broken in prod'
• Share environments within and between Dev and Ops teams
• Simplifies the automation of building test environments

Future directions

• Test patches easily (drush --iq)
• Continuous Integration (Jenkins) VM
• End-to-end workflow automation
