Automating application deployment (a WordPress example)
Chef can also be used to deploy applications from code repositories. It combines one of the most complete, feature rich, and complicated Chef resources available—the deploy
resource—and the various powerful and popular cookbooks, such as the database
cookbook. We'll show you how to deploy a simple WordPress application right from the GitHub repository, creating a dedicated database and user as well as all the required dependencies. This builds on what has already been done previously, but the resources and cookbook shown here are made to be reusable anywhere.
