Learn Kubernetes Weekly issue 198 · 26 Aug 2026

Data Lakehouse Infrastructure, Kubernetes Tool Trends, Kafka Performance Lessons, CODECO Architecture, AI Deleted Wrong Deployment

This newsletter is brought to you by LearnKube — master Kubernetes with hands-on training designed for engineers who want to learn the smart way.

We published a free, 342-page technical guide to Kubernetes rightsizing.

The guide covers:

  • How Kubernetes requests and limits work.
  • Which container, runtime, and application metrics you can trust.
  • How to apply changes safely with policy, GitOps, rollouts, and rollback conditions.
  • Where AI can help without receiving unchecked production authority.

This is by far the longest book I've written with Gulcan! There's so much to say about requests/limits 😅

Articles

  1. Data Lakehouse: Infrastructure

    medium.com

    This case study walks through how Fresha built a scalable AWS-backed Data Lakehouse using EKS, Flink and StarRocks, bringing real-time streams and batch analytics together in one platform.

  2. What the Popularity of Emerging Tools Tells Us About Kubernetes' Future

    kube.today

    Drawing on more than 100 KubeFM conversations, this article shows how tools like Karpenter, KRO, Argo CD, OpenTelemetry, Kueue, and Kgateway are shaping autonomous infrastructure, platform engineering, and AI workloads.

  3. Kafka on Kubernetes: Performance Lessons for Any Disk-Heavy Data Service

    dev.to

    This case study traces why Kafka started reading from disk after moving from EC2 to EKS, and lands on cgroup v2 reclaim pressure.

  4. To Centralise or Not to Centralise: The Questions That Shaped the Kubernetes CODECO Federated Architecture

    medium.com

    This article explains the centralise-or-not trade-off behind CODECO's federated Kubernetes architecture across cloud, edge and IoT, and how neighbourhood-scoped control, decentralised AI and federated scheduling answer it.

  5. Your AI just deleted the wrong deployment. Now what?

    medium.com

    This article argues that MCP servers for Kubernetes ship the accelerator without the brake, and walks through a two-tier design in which an agent can only propose a change, and a human approves the exact plan before it is applied.

  6. My Experiments with MCP: Moving Beyond the “Agent Wrapper”

    godfreym.medium.com

    This article presents a proof of concept in which an Elasticsearch MCP server runs on Kubernetes so an SRE agent can search logs in plain language, and it ends with the authentication and RBAC work still needed for production.

The Technical Guide to Kubernetes Rightsizing

Guessing at CPU and memory limits again? We've all been there.

This guide walks through the whole rightsizing journey, from messy metrics to safe production changes, and shows where AI actually helps (and where it doesn't).

Tutorials

  1. Building a Real k6 Test Suite Against a Live Kubernetes App

    dev.to

    This tutorial builds a real k6 test suite against Google's Online Boutique running on a home lab Kubernetes cluster, with a shared client library, smoke, load, stress, and browser tests, and the two bugs the first run exposed.

  2. From Ingress to Gateway API: How We Modernized Networking on Our GKE Cluster

    medium.com

    This tutorial explains why Gateway API replaces Ingress on GKE, walking through GatewayClass, Gateway, and HTTPRoute, then sets up traffic splitting and TLS without vendor-specific annotations.

  3. Deploying WSO2 API Platform Gateway on OpenShift: A Practical Guide

    medium.com

    This tutorial walks through deploying the WSO2 API Platform Gateway on OpenShift, from building the images and installing cert-manager to applying the gateway operator, a sample REST API, and the route that exposes it.

  4. Autoscalable GitLab runners on AWS EC2

    palark.com

    This tutorial shows how to replace always-on EC2 runners with autoscaling GitLab runners using the AWS fleeting plugin and an Auto Scaling Group, so instances start per job and shut down when the queue is empty.

Why Kubernetes Needs to Learn GPUs

Kube Signals starts where the keynote ends: with the trends that platform teams will have to operationalize next.

In this special episode, Brian Teller speaks with Saiyam Pathak about his KubeCon India keynote and the shift from developer platforms to AI factories. They examine what GPU scarcity, shared accelerators, and AI workloads mean after the conference slides meet real infrastructure.

In this interview:

  • Why GPU infrastructure is becoming a platform-engineering concern
  • How DRA, HAMI, MIG, and MPS change GPU allocation and utilization
  • Where isolation, scheduling, and observability become harder for AI platforms
  • Which cloud-native AI trends and projects platform engineers need to watch

Code & tools

  1. KubeElasti: scale services to zero without dropping requests

    github.com/kubeelasti

    KubeElasti scales idle Kubernetes services down to zero and wakes them on the first request, holding that traffic in a proxy queue so nothing is lost while the pods start.

  2. Kubernetes IPsec Connection Operator

    github.com/dialohq

    IPMan is a Kubernetes operator that automates IPSec VPN setup (via StrongSwan) so your workloads can securely connect across networks.

  3. OpenDepot

    github.com/tonedefdev

    OpenDepot is a self-hosted, Kubernetes-native registry for your OpenTofu/Terraform modules and providers, so you control distribution and versions rather than relying on the public registry.

  4. Klarity

    github.com/selvarajmurugesan90

    Klarity is a read-only Kubernetes dashboard for GitOps teams: it shows everything running in the cluster but never lets anyone change it outside Git.

  5. kstack: Claude Code skill pack for Kubernetes operations

    github.com/kubetail-org

    kstack is a skill pack for Claude Code that runs monitoring, troubleshooting and audit tasks on your clusters, handing the heavy shell work to tools like Kubetail, Helm and Trivy to keep answers fast.
