30. Converge Testing
32. CaaP! vs! IaaP

91. Cookbook Dependencies
92. Often, a cookbook will depend on another
93. include_recipe ‘another_cookbook::recipe’! ! OR! ! consume a resource shipped in another_cookbook
94. For example
97. not in core Chef
98. ships in mysql cookbook
101. Dependencies suck and you don’t want to manage them manually.
103. Berkshelf is bundler for Chef cookbooks
105. your chef-server here
107. Bundler installs dependencies into your local gem cache
108. Berkshelf installs dependencies into your local cookbook cache
115. needs moar ServerSpec
116. Continuous Integration
117. This is all driven from the command line
118. Which makes it super easy to wire into CI systems
119. CI should watch version control for commits
120. Polling! vs! Notifications
121. I ran out of slides!
