Kubernetes is turning 11, so I'll be celebrating its birthday by giving you some open source tools that will help you cause chaos. Chaos engineering is part science, part planning, and part experiments. It's the discipline of experimenting on a system to build confidence in the system's capability to withstand turbulent conditions in production. Before I start passing out the gifts, in this introductory article, I will explain the basics of how chaos engineering works.

Imagine the chaos that would occur if all open source software vanished with the snap of a finger. Picture the devices that would turn to bricks in our hands, the infrastructure that would fail, and the machinery that would fall silent. The truth is we probably don't stop to think about all the open source libraries, frameworks, and components we depend on—until something goes wrong.

Advertising is central to the internet economy. It funds many free products and services. But it is also very intrusive.

While working on a continuous integration/continuous development (CI/CD) solution for a customer, one of my first tasks was to automate the bootstrapping of a CI/CD Jenkins server in OpenShift. Following DevOps best practices, I quickly created a configuration file that drove a script to complete the job.

I was once asked why computers are called "computers" when they do so much more than compute numbers. A modern PC browses the internet, plays audio and video, generates beautiful graphics for video games and movies, simulates and predicts complex weather patterns and epidemiological risks, brings architectural and engineering blueprints to life, and much more. The reason computers can do all of this because all these problems can be expressed as numerical equations, and the computer's CPU—its central processing unit—is actually little more than a simple calculator. read more
