  1. 1. Chef for OpenStack OverviewOpenStack Summit April 2013Matt RayOpscode
  2. 2. Why Chef?
  3. 3. Chef is Infrastructure as Code • Programmatically provision and configure • Treat like any other code base • Reconstruct business from code repository, data backup, and bare metal resources.
  4. 4. Declarative Interface to Resources• Define policy• Say what, not how• Pull not Push
  5. 5. Ruby!extra_packages = case node[platform] when "ubuntu","debian" %w{ ruby1.8 ruby1.8-dev rdoc1.8 ri1.8 libopenssl-ruby } endextra_packages.each do |pkg| package pkg do action :install endend
  6. 6. Recipes and Cookbooks• Recipes are collections of Resources• Cookbooks contain recipes, templates, files, custom resources, etc• Code re-use and modularity• Hundreds already on
  7. 7. The Chef Community• Apache License, Version 2.0• 1300+ Individual contributors• 200+ Corporate contributors • Dell, DreamHost, HP, Rackspace, VMware, SUSE and many more• 900+ cookbooks•
  8. 8. Chef and OpenStack?Thats great and all, but tell me about OpenStack!
  9. 9. Deploying OpenStack• Chef ties it all together automatically• Scaling changes how we deploy• Interchangeable components• Configurations shared, supported & documented• Licensing makes it available to everyone
