FAQs

Where are the katas?

Katas are located in the katas directory. They all have unique names. They are not in any particular order, feel free to start with any that you find interesting.

You can contribute your own katas. To know how, look at the Contributing section.

Tell me more about kata

To paraphrase from the Wikipedia entry on kata:

The basic goal of kata is to preserve and transmit proven patterns and techniques. By practicing in a repetitive manner the learner develops the ability to execute those patterns and techniques in a natural, reflex-like manner. Systematic practice does not mean permanently rigid. The goal is to internalize the patterns and techniques of a kata so they can be executed and adapted under different circumstances, without thought or hesitation.

Tell me more about DevOps kata

In order to define a DevOps kata, we must first define DevOps. The philosophy is that you want to adopt practices that enable you to build quality and flexibility into your software. You also want to adopt a culture that enables members of your team to collaborate effectively.

Coming back to DevOps kata, perhaps it is best to start with an example:

Make a change to a web application without taking it down. Users must not be interrupted at any time during the change.

This can be solved in different ways - for example perform rolling restarts on your application server, OR provision an entirely new server and switch over your load balancer. Each approach has costs and benefits. Practicing them both will let you make a better informed decision the next time such a requirement comes up.

We do these things regularly, but a kata would let you take a more systematic approach to things, by writing down what you did and sharing it with a wider audience for feedback.

Contributing

A good DevOps kata:

  • has a tangible objective
  • is a common problem/pattern addressed by DevOps
  • is solvable in more than one way
  • is designed to help a learner get better
  • is framed as a question and a set of considerations that guide the learner along

This repository is built by and for the community. We would love to get inputs from you. Feel free to add your own kata in the katas directory and send us a PR. Remember to also add the kata to the list of katas on this README.
