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

1. “How LinkedIn moved its Kubernetes APIs to a different API group” by Ahmet Alp Balkan & Ronak Nathani Butler, LinkedIn.

“We recently migrated one of LinkedIn’s major internal custom Kubernetes APIs to a new API group, while also introducing major changes to the API. [..] This article will explain why we moved this API between Kubernetes API groups, the limitations of the API versioning machinery in Kubernetes, and how we created our own solution – a “mirror controller” – to seamlessly migrate to a new API while the old API was actively being used.”

2. “Argo Rollouts – What Is It, How It Works & Tutorial” by James Walker, Spacelift.

“This article will explain more about Argo Rollouts, how it works, and how to get started using it in your own cluster. We’ll finish by sharing a simple example of how to launch a canary rollout for a Kubernetes deployment.”

3. “Kubernetes security fundamentals: Authorization” by Rory McCune, Datadog.

“In this post, we'll focus on another key aspect of Kubernetes security: authorization, which allows a cluster to know if the requester is allowed to take a specific action. Authorization is the second step (after authentication) in the process that requests to the main API server go through before they’re applied to the cluster.”

4. “Full-Guide: How to Easily Publish Helm Charts on GitHub with GitHub Pages” by Artem Lajko.

“In this short blog, I am going to show you how you can easily publish your locally written Helm chart on GitHub using GitHub Pages. We will cover the following steps: Create a Helm Chart; Create auto releases; Use GitHub workflows to generate Helm docs on push; Automated test the Helm chart on a Kind cluster after push; Publish it on GitHub using GitHub Pages; Use the published Helm Chart; Add the Helm Chart to artifacthub.io.”

5. “ArgoCD/Flux vs Kluctl” by Alexander Block.

“Kluctl is very flexible when it comes to deployment strategies. All features implemented by Kluctl can be used via the CLI or via the Kluctl Controller. This makes Kluctl comparable to ArgoCD and Flux, as these projects also implement the GitOps strategy. This comparison assumes that you already know Flux and/or ArgoCD to some degree, or at least have heard of them.”

Can the automatic shutdown of your Kubernetes workloads be beneficial? It could cut your cloud costs and reduce your carbon footprint. The new sleepcycles tool aims to do just that, allowing you to:

- Define the working hours (shutdown & wake up schedule) for your K8s resources using the cron expressions;
- Specify these schedules for Deployments, CronJobs, StatefulSets, and HPAs (HorizontalPodAutoscalers);
- Specify the needed time zones;
- Use these features for applications provisioned with Argo CD.

The project is implemented as a Kubernetes controller following the K8s operator pattern. It’s written in Go and can be installed via a Helm chart.

How about starting this week with favourite Kubernetes interview questions?

Here are the top interview questions about K8s, based on a recent discussion on Reddit and its users’ feedback:

- What’s the difference between a Pod, a Service, and a Deployment?
- Let's say you are joining a company and you are working with several product teams that have already undergone the process of containerizing their applications. How would you go about deploying and operating these applications?
- Can you explain to me how applications in Kubernetes accept traffic from clients?
- Can you describe the specific steps that are happening when a client hits a load balancer that's pointing to your Kubernetes nodes?
- How do you troubleshoot a CrashLoopBackOff?
- My application in a Pod is unable to reach the API server via the kubernetes endpoint. Can you debug this issue for me?
- If I want to ensure some data survives a Pod restarting how would you do it?

… and perhaps the funniest of all those questions:

- If you were a Kubernetes resource, what would you be and why? 🤣

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.”

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.
