The document provides an overview of the Chef software platform, which is an automation framework that enables infrastructure as code through reusable definitions. It details core building blocks such as resources, recipes, cookbooks, roles, and environments, explaining their functionality and how they interact. The document also includes links to additional resources for learning and installation of Chef.

- 4. Building Blocks Cookbooks Recipes Resources
- 5. Building Blocks: What is a Resource? • A Resource is a system state you define • Example: Package installed, state of a service, configuration file existing • You declare what state you want the resource in. • Chef automatically determines HOW that state is achieved On Linux based OSes: On Windows based OSes:
- 6. Building Blocks: What is a Recipe? • A recipe is a collection of Resources • Resources are executed in the order they are listed. On Linux based OSes: On Windows based OSes:
- 7. Building Blocks: What is a Cookbook? • A cookbook is a set of recipes • A cookbook is a defined set of items and different outcomes that you expect to address • A cookbook could have a recipe to install apache2/httpd but also another set of recipes to activate modules required.
