1. "Kubernetes In Anger" by Samuel Vijaykumar Madireddy.
This guide is not for beginners. There’s a gap between knowing Kubernetes concepts (pods, deployments, services, kubectl) and actually being able to keep an EKS cluster healthy in production. [..] What you will find: what to do when pods are Pending and you don’t know why, how to tell if DNS is the problem or just a symptom, why your NLB keeps resetting connections, and how to collect evidence before the cluster auto-heals and destroys your ability to do an RCA.
2. "What kubectl debug doesn’t tell you: The silent evidence gap" by Shamsher Khan.
A kubectl debug session can contain the only direct observation of a failing system state. [..] Once the pod state changes, the Kubernetes API no longer exposes the termination context of that debug session. The exit code that encoded your finding, the duration of the session, which container you targeted — is not retained by the Kubernetes API after subsequent pod updates. Here is what that looks like, and what it means for your incident response workflow.
3. "Static web hosting on Kubernetes with OCI images as volumes" by Kowalski7cc.
Introduced in Kubernetes 1.31, promoted to beta in 1.33 and entered in stable with Kubernetes 1.36, we can use OCI images as volumes for containers. They are now a possible storage choice among Persistent Volume Claims, empty directory, pod metadata, Config Maps and Secrets. This option can take advantage of the existing tooling and CI/CD already present to deliver an archive containing any kind of data.
4. "Kubernetes Gateway API" by Roman Glushko.
We have covered a lot of ground here. We traced the evolution of Kubernetes ingress patterns from the early days of Kubernetes to the Gateway API era. Then we stopped at Gateway API and went deeper into the protocol itself. [..] Finally, we looked at available Gateway API implementations and how to think about picking one.
5. "Kyverno in Action: Policy-as-Code Admission Control for Kubernetes" by Sergei Olshanetski.
In this article, we’ll build a complete Kyverno demo on Minikube. We’ll start with an open cluster, layer on one policy at a time, and end with a hardened production baseline that includes Cosign image signature verification, automated tenant onboarding, and TTL-based cleanup. Every step runs on your laptop.
6. "The feedback loops behind Kubernetes" by Fatih Arslan, PlanetScale.
Before we look at a single line of Kubernetes, we're going to run a production database by hand and slowly let the feedback loop appear on its own. Then we'll map that loop to Kubernetes, with the pieces production needs: a store, watches, queues, retries, and more. At the end, we'll look at what one of these loops looks like in a real operator.
7. "Writing a Kubernetes Operator in the Age of AI" by Fernando Villalba, Numtide.
Six months into building a production Kubernetes operator for Multigres with AI, the code stopped being the hard part. Most of the effort went into design, hygiene, continuous improvement, and review. What I learned in 1,303 commits is that the best way to use AI is to build a factory floor of specialists you orchestrate yourself.
