Get started with Chef by taking Chef Essentials. It’s a two-day instructor-led course that covers all the basics. You’ll learn what it means to turn infrastructure into code so that you can automate the configuration, deployment and management of your servers. You’ll also learn about Chef architecture and the set of tools included in the Chef Development Kit (ChefDK). Finally, we’ll show you how to test your infrastructure code so that you can deploy with confidence. Each of the core units includes hands-on exercises that will give you confidence in your new skills. At the end of the course, you’ll come away with a repo and the skills to start automating your own infrastructure.
