Using Shef, the Chef Shell
The Chef Shell (Shef) is a powerful wrapper around an Interactive Ruby (IRB) session that allows Chef admins to easily debug recipes. With the ability to emulate both a Chef Solo and regular Chef Client, it's an incredibly valuable tool for doing anything from basic expression evaluation to in-depth debugging.
This session will provide an introduction to Shef and demonstrate how it can be incorporated into your daily workflow.
