Chef Intermediate Topics - Online
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 expand 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 managing your infrastructure.
Two day course agenda:
- Why write tests? Why is that hard?

This was the best course I've ever taken. The instructor was just GREAT!
Even though I've been using Chef for three years, I found this class immensely useful; not only did it allow me to examine and compare my current practices to those presented in the training, but I learned several new techniques for using Chef tools.
this is a great class, with great content and mentor
I will recommend this class to my organization as one of the more complete solutions to on boarding new Chef users.
I was sad to have the training end! The personalized attention from the instructor was priceless. Chef made sense and I LOVED it! Every question and problem were solved and explained. Truly craft masters of Chef, take this and be ready to be amazed. I'm applying what I learned the next week after the course. Thank you CHEF!
Class was excellent, and the Instructor was even better! Robin Beck is the best!
This was the best training class I've taken. It was online using Zoom, it was super easy to share code and collaborate. The instructor kept everything going at a perfect pace and his knowledge and expertise on the topic was evident. 22 years of training in my career and this was hands down the best class I've taken. Better than classroom training. Looking forward to more!
It was great.
