Chef Habitat is a workload-packaging, orchestration, and deployment system that allows you to build, package, deploy, and manage applications and services without worrying about which infrastructure your application will deploy on, and without any rewriting or refactoring if you switch to a different infrastructure. Habitat separates the platform-independent parts of your application—the build dep

This diagram shows how you develop, test, and deploy your Chef code. What’s New¶ The following

Elements of good approaches to building cookbooks and recipes that are reliable include: A consistent syntax pattern when constructing recipesUsing the same patterns in RubyUsing resources included in Chef Infra Client or community cookbooks before creating custom onesIdeally, the best way to debug a recipe is to not have to debug it in the first place. That said, the following sections discuss va

A cookbook is the fundamental unit of configuration and policy distribution in Chef Infra. A cookbook defines a scenario and contains everything that is required to support that scenario: Recipes that specify which Chef Infra built-in resources to use, as well as the order in which they are to be appliedAttribute values, which allow environment-based configurations such as dev or production.Custom

A role is a way to define certain patterns and processes that exist across nodes in an organization as belonging to a single job function. Each role consists of zero (or more) attributes and a run-list. Each node can have zero (or more) roles assigned to it. When a role is run against a node, the configuration details of that node are compared against the attributes of the role, and then the conte
