Problems with Current Approach of Developing Cookbooks

• Every time a correction is made to the cookbook, version is changed and new version is uploaded to chef server
• This leads to incorrect cookbooks for some versions.
• Solution is to upload only stable cookbook versions to chef server.
• The Answer to solve this is Test Kitchen.

Test Kitchen

• This is testing environment for chef cookbook development.

• Workflow

  • Develop Cookbook
  • Test cookbook
  • Uplod cookbook to chef server

• Test Kitchen has drivers. Driver is the virtual environment where the servers are created. Driver Examples are

  • AWS
  • Azure
  • Docker
  • Vagrant

• In Test Kitchen,

  • a test vm gets created using the driver configure.
  • In this Test VM Chef Zero/Chef solo (Chef server and chef node on same machine)
  • Run list gets executed and logs, results are shared.

• Whenever you create a cookbook, kitchen.yml file is created. This is the configuration file for test kitchen.

• In kitchen.yml file the default configuration will be using driver vagrant.
