  • 15. Validation• Cookbook versions and their dependencies exist• Environment names and referenced cookbooks are correct• Role names and referenced roles and cookbooks are correct• Data bags parse, secret keys are present• Node run lists items are correct and their Environment exists
  • 16. Whats the Point?• Nodes are ephemeral• Everything we do is in code.• Everything is checked into version control.• Basic roadmap for deployment. http://www.flickr.com/photos/mrchippy/443960682/
  • 17. Break it DownHow do we recreate our infrastructure? http://www.flickr.com/photos/mrchippy/443960682/
  • 18. Real World Example• Whiteboard it out• Break it down into components• Comment it all out and start working http://www.flickr.com/photos/mrchippy/443960682/

  • 21. Versioned Infrastructure• Documentation for your deployment• Iterate over it• Stored in version control• Share with others http://www.flickr.com/photos/mrchippy/443960682/
  • 22. Whats Next?•Extract from chef-repo•Extract from Chef Server•Execute as knife plugin http://www.flickr.com/photos/mrchippy/443960682/
