IntroductionCourse Outline

The Chef configuration management course will provide attendees with an understanding of the principles of DevOps and shows students how to use OpsCode Chef as a tool to manage computing infrastructure.

Chef can run in client/server mode, or in a standalone configuration named "chef-solo". In client/server mode, the Chef client sends various attributes about the node to the Chef server. Chef recipes can query these attributes and use the resulting data to help configure the node.

In this Chef configuration management attendees will learn how to:

  • Create recipes and cookbooks for standard infrastructure management
  • Use the OpsCode Chef infrastructure to manage nodes
  • Use the ‘Ohai’ tool to understand the facts captured by Chef.
  • Use the ‘knife’ tool to interact with the Chef server and bootstrap nodes.
  • Use TestKitchen to test Chef cookbooks.
  • Use Foodcritic and Rubocop to check cookbooks for common problems.
