We'd like changes to our Cookbooks to be automatically tested and deployed using our CI system. Additionally, these Cookbooks must also be automatically propagated to our end-users (developers).

Workflow (today)

Our current workflow is as follows:

  1. Jim, the developer, commits a change to the webapp Cookbook, and pushes that change to Github.
  2. Jenkins, the Continuous Integration system, checks-out the updated webapp Cookbook repo and runs its tests using test-kitchen.
