What is Chef and how does it work?
Chef is an automation platform that transforms infrastructure into code, allowing you to manage and configure systems consistently across various environments, including cloud, on-premises, and hybrid setups. It operates on a client-server model where the Chef server stores configurations, policies, and recipes. The Chef client, running on nodes (machines), communicates with the server to retrieve and apply these configurations, ensuring the desired state of the system.What are cookbooks and recipes in Chef?
In Chef, a cookbook is the fundamental unit of configuration and policy distribution. It contains recipes, attribute values, custom resources, files, templates, and other necessary components to support a specific scenario. Recipes specify which Chef Infra built-in resources to use and the order in which they should be applied. Cookbooks are authored, tested, and maintained on workstations and then uploaded to the Chef Infra Server.How do you handle dependencies in Chef?
Chef manages dependencies through the use of cookbooks and their associated metadata. The `metadata.rb` file within a cookbook describes the cookbook itself and any dependencies it may have. When a cookbook is uploaded to the Chef Infra Server, Chef resolves these dependencies to ensure that all required components are available before applying the configurations.What is the role of the Chef Workstation?
The Chef Workstation is a package that includes all the tools necessary for developing, testing, and maintaining Chef configurations. It includes tools like Chef Infra Client, Chef InSpec, Test Kitchen, ChefSpec, and Cookstyle.
