Practical Puppet: Systems Building Systems

on YouTube ↗28m

" summary

Launches an EC2 AMI using user-data that runs Puppet to install Ruby, gems, MySQL, Apache + Passenger and a Rails app; the AMI build runs about 15 minutes (optimizable to 4–5 minutes). Puppet code declares resources, uses the gem provider, enforces idempotency and resource ordering, and notifies service reloads. Continuous integration + rspec validates resulting images; a demo instance boots, the public DNS is posted to Twitter, and the Rails welcome page comes up.
