87. Cookbook Dependencies

88. Often, a cookbook will
depend on another

89. include_recipe ‘another_cookbook::recipe’!
!
OR!
!
consume a resource shipped in
another_cookbook

90. For example

93. not in core Chef

94. ships in mysql
cookbook

97. Dependencies suck and
you don’t want to manage
them manually.

102. Berkshelf is bundler for
Chef cookbooks

104. your chef-server here

106. Bundler installs
dependencies into your
local gem cache

107. Berkshelf installs
dependencies into your
local cookbook cache

114. needs moar ServerSpec

115. Travis CI

116. Because I like to close my
laptop sometimes
