Chef Intermediate Topics is an instructor-led course that first introduces you to test-driven development (TDD) and then shows you how to extend your cookbooks with custom resources and Ohai plugins.

Building cookbooks with tests will increase the speed at which you work by giving you consistent feedback throughout the entire cookbook development process. Extending your cookbooks with custom resources will increase clarity within your recipes and provide resources that are portable to other cookbooks. Ohai plugins gather data from your nodes that will aid in more dynamic recipes and extensive reporting.

In this course, you will learn how to confidently refactor and extend a cookbook through explanation, demonstration, practice, and discussion. At the end of the course, you will have created a code repository that can be applied to solve the unique challenges you face when managing your infrastructure.
