This document discusses using Drone.IO and GitHub for automated testing of Chef cookbooks. Drone.IO is a continuous integration/delivery tool that watches GitHub repositories for code changes and then builds Docker images to run tests defined in a .drone.yml file. The document provides information on installing and configuring Drone, how it works, and recommends using a tool called Meez to generate testable Chef cookbook structures. It emphasizes that Chef cookbooks should be treated as code by using source control and testing tools like those discussed.

Runs Docker image
Runs a series of commands
Performs action based on result

21. Why use Drone ?
Same tooling for both Public and Private
Ultra fast - Docker FTW
Opensource

22. It’s not all rainbows and unicorns

39. As a NoOp I need a development
workflow with automated CI for
building reliable infrastructure using
chef cookbooks for my DevOps
environment.

40. “Chef cookbooks
are code.”

41. culture, culture, something,
learning organization, something,
devops...

46. Shameless plug… Meez
A tool I wrote … to scratch an itch.
generates a chef cookbook with plumbing for all the testing
tools in the previous slides … and more.

47. Generate a testable cookbook

48. Run tests!

49. Short feedback loops
Guard: run tests every change
