Introduction Kubernetes 1.34 is scheduled to reach its upstream end-of-life (EOL) on October 27 , marking the cessation of all security patches and critical updates from the Kubernetes project for this version. However, for organizations leveraging managed Kubernetes services such as Amazon EKS…
A hands-on look at how etcd works, why it uses a flat key-space for hierarchies, and how MVCC handles state updates under the hood. Episode 5 of K8s with Pravesh Hola Amigos 👋 Welcome back to K8s-with-Pravesh . In the first few episodes, we covered the holistic journey of Kubernetes internal…
Kubernetes 1.34 reaches end of life upstream on October 27, 2026 . If you run it on EKS, GKE, or AKS, that date by itself changes very little. Each provider keeps its own support clock, and each one does something different when that clock runs out. EKS upgrades your control plane without notice.…
Las pruebas de email en CI fallan de una forma engañosa: el job termina en verde, pero el mensaje de verificación nunca llega a la bandeja que el test está leyendo. Un SLO pequeño y medible convierte ese misterio en un incidente operable. El síntoma: CI verde, correo perdido En un pipeline de…
Namespaces are a good isolation boundary right up until two teams need different cluster-scoped things. The first time one team wants a newer operator CRD, or a webhook configuration that does not match the rest of the cluster, the argument stops being about YAML and starts being about tenancy. A…
Originally published on DevToolHub . Kubernetes OOMKilled with exit code 137 means the Linux kernel killed your container's process for using more memory than it was allowed. Sometimes that's the container's own memory limit. Sometimes the whole node ran out of memory and your container lost the…
By Yaala Labs Some workloads are never leaving the building. Patient records. Trade surveillance feeds. Customer data that a regulator, a sovereign-cloud mandate, or a signed contract says must stay on hardware you control. The teams responsible for that data are also, very often, the teams that…
Most Kubernetes teams debug their platform in the one place it does not run: their laptop. Production is 82% likely to be Kubernetes ( CNCF Annual Cloud Native Survey , 2025, up from 66% in 2023), yet the local dev loop is often a Docker Compose file that quietly disagrees with the real cluster on…
Monday, 9am. First coffee. First Slack message of the week: "Who changed prod this weekend?" Silence. There was a freeze. Everyone agreed on it. It was pinned in the channel. A pipeline ran anyway, because pipelines don't read Slack. Kubernetes knows who can change production. It has no idea when…
If you're learning Kubernetes, here's a question you should be able to answer: What happens when a production Pod suddenly disappears? Not theoretically. Let's actually think through it. Imagine your application has: 3 Pods ↓ frontend frontend frontend Then someone runs: kubectl delete pod…
