Managing Web Application Servers with Puppet
Joshua Sierles of 37signals once described configuration management as something that "doesn't sound sexy, but it's the single most important thing we do as sysadmins" but what is it and what do tools like Chef and Puppet offer from the point of view of a developer?
In this presentation to the London Ruby User Group, Paul Mucur talks about how configuration management allowed him -- a developer with no access to the live servers and working with system administrators in a different time zone -- to not only install and configure servers quickly and in a repeatable way, but also let him feel confident about the consistency of each and every machine to which he deployed.
Using the example of getting a server ready to run a Rails application using Puppet (and testing things out with the aid of Vagrant), Paul showcases some patterns that he has developed for managing versions of Ruby with RVM, the installation of Phusion Passenger and how to deploy a database.yml when you're not allowed to see live passwords.
