Presentation given at the Denver Puppet user group. A copy of the files can be found at https://github.com/jscelza/vagrant_oscar_example. The purpose of this presentation was to walk the group thru how i used Vagrant and Oscar to development Puppet modules locally. Thanks to Adrien Thebo for all his work on the plug-in https://github.com/adrienthebo/oscar

2. What is Vagrant?
● Marketing: Create and configure lightweight, reproducible
and portable development environments
● Operation: Provides a disposable environment and
consistent workflow for developing and testing infrastructure
management scripts
● Developer: Isolates dependencies and their configuration
within a single disposable consistent environment, without
sacrificing any of the tool you use.
