Chef Tutorials: Example of Chef Recipe Program

What is Chef Recipe?

A recipe is the most fundamental configuration element within the organization. A recipe:

• Is authored using Ruby, which is a programming language designed to read and behave in a predictable manner
• Is mostly a collection of resources, defined using patterns (resource names, attribute-value pairs, and actions); helper code is added around this using Ruby, when needed
• Must define everything that is required to configure part of a system
• Must be stored in a cookbook
• May be included in another recipe
• May use the results of a search query and read the contents of a data bag (including an encrypted data bag)
• May have a dependency on one (or more) recipes
• Must be added to a run-list before it can be used by Chef Infra Client
• Is always executed in the same order as listed in a run-list
