Here goes our latest bunch of interesting Kubernetes-related articles recently spotted online:

1. “Kubernetes Security Guide (Kubernetes Hardening)” by ReynardSec.

“This article discusses the topic of securing the configuration of Kubernetes clusters. [..] my goal is not merely to present a dry list of parameters and ready-made configuration snippets but to provide the reader with a fuller context. I want the reader to understand why certain modifications are necessary and what benefits their implementation will bring. Theory and practice must go hand in hand! Therefore, I have prepared a tool for you that will allow you to test everything I write about here in your local environment. You will find a script here that will easily start your Kubernetes cluster.”

2. “How we migrated onto K8s in less than 12 months” by Ian VonSeggern, Figma.

“At Figma, we need to be sure that any decision we make—whether it’s about user-facing features or back-end infrastructure—will leave the platform in a better position than when we started. The larger and more resource-heavy the workstream, the more confident we need to be that we’ll be able to complete the effort in a reasonable timeline without causing downtime to users. That’s why we didn’t take the decision to migrate our core services to Kubernetes lightly. Here’s a look at our process of evaluating, scoping, and executing the move.”

3. “K8s Vertical Pod Autoscaler's Algorithm” by Tanay Tummalapalli.

“I tried to understand how the Vertical Pod Autoscaler(VPA) works [..] I wanted to dig deeper to get at the essence of the recommender’s algorithm. This is my attempt to document my digging.”

4. “Kubernetes: The Art of Zero-Downtime Deployments” by Gulcan Topcu.

“This blog post will guide you through the techniques you need to achieve seamless deployments in Kubernetes. We’ll also put these strategies into practice using a knowledge-powered customer support chatbot. We’ll explore various deployment strategies, such as Blue/Green and Canary, sharing real-world examples and key metrics to monitor along the way.”

5. “Generating, transforming, and patching Kubernetes configuration with Kustomize” by Brian Grant, original lead architect of Kubernetes.

“Kustomize is a fairly unique tool, at least among the dozens of Kubernetes configuration and Infrastructure as Code tools that I’m aware of, and certainly it’s the most popular tool in its class. Why did we create it?”

Have you considered using or maybe even used KubeInvaders to make chaos engineering in Kubernetes fun? It features a new demo now! But first, let’s recall what this tool is about.

KubeInvaders describes itself as a “gamified Chaos Engineering tool for Kubernetes,” which sums it up perfectly. There was a classic shoot 'em up arcade video game from the 70s, Space Invaders, involving a laser cannon to shoot rows of aliens. This project mimics it by using your actual Kubernetes Pods as aliens you’re shooting. It comes with various features, including:

- Shuffling the positions of the Pods to be killed;
- Randomly switching between namespaces;
- Showing you online stats (running/not running/deleted Pods) and events;
- Exposing Prometheus metrics;
- Programming mode (beta) to define your chaos experiments in YAML.

Now, the project also has a live demo, meaning you can open your web browser and play with KubeInvaders against a preconfigured Kubernetes cluster.
