Fletcher Nichol – Kitchen CI


We use Test Kitchen to test our continuous integration software at Safari Books Online. We run it on LXCs on both vagrant and testing nodes in our continuous integration pipeline. I was curious to see what was new with Kitchen CI and what Fletcher had to say. We use the framework in a standard way, though I learned the

kitchen diag

command, which is short for ‘kitchen diagnose’, and helps diagnose errors within Test Kitchen. I also learned how easy it is to test operating systems outside our current production systems with Kitchen CI. This would be useful to test cookbooks that we planned on releasing to the community. We could get a sense of what other OSes were already supported and what work would need to be done in order to support them if not.

Jamie Windsor – Berkshelf

We use Berkshelf to manage our cookbook dependencies. We love it and it works well. Jamie talked about the vision for Berkshelf 3.0 and how the product has been improved. I downloaded and installed the new Chef DK to play with which included both Berkshelf 3 and Kitchen CI. His talk details how artifacts are more strictly regulated in Berkshelf 3. Jamie also spoke about an online game platform he build using Elixir. He will be speaking more about it at the Atmosphere Conference in Poland.

Rachel Chalmers

Rachel said something that has stuck with me and I have repeated many time since. To paraphrase,

Automation Software is the Codification of Institutional Knowledge

I love that idea. Chef recipes are self-documenting processes for other engineers to learn from. What was once stored inside one person’s head is now codified with recipes. I love the concept!

My big take-away from this talk:

Automating everything allows your business to pivot.

Big and small companies need to pivot; markets change and businesses change. If your infrastructure creation is automated, you can pivot from one direction to another more easily and in a safer, testable way.

Justin Arbuckle


Justin gave a great talk on automation software in our contemporary corporate culture. He used the story of Moby Dick to illustrate different struggles we face. This was a delightful talk with fantastic artwork by Matt Kish.

The Take-Away


It is easy for departments to live in silos. The current trend is to find ways to diminish the time wasted handing off tasks from one department to another. We’ve taken some of the recommendations to heart at Safari Books Online already. Historically, we’ve supported two Jenkins servers: one for IT and one for Engineering (Development). We have two source control repositories. We did this with good intentions: to stay out of each other’s way. For new projects that involve both departments, we try to consolidate source control and testing to the Engineering infrastructure. We now have software developers writing deployment cookbooks, which is exactly the direction we want to go. We have a long way to go, but this is a start.
