How vagrant works

Basic VagrantFile

• Vagrant box file can be obtained from 3 places

Three methods to create a box file

Method Pros Cons

Download a box file from http://www.vagrant.es

- Simplest - Up and running quickly

- You don’t know whats on the base box

Using the instructions off vagrantup.com

- Gives understanding of the specifics of a vagrant box setup

- Time consuming. - Miss a step or do a step wrong and you have a vagrant box which has odd behaviour

Using the opensource project VeeWee off github
