Self-Healing Registry Mirror, Migrating to Fly.io, Kubeshark Packet Visibility, Temporal.io in Production, Tracking Kubernetes Costs
This newsletter is brought to you by LearnKube — master Kubernetes with hands-on training designed for engineers who want to learn the smart way.
Hi,
We published a new page for companies interested in working with us, LearnKube.!
We want to keep creating ambitious technical education for Kubernetes and platform engineering teams, and already have ideas we’d like to develop around AI infrastructure, Kubernetes resource optimization, platform engineering, and general Kubernetes education.
If your company wants to support these efforts and reach Kubernetes practitioners with useful technical content, get in touch!

Articles
We built a self-healing registry mirror (because Docker hub rate limits are no fun)
tinysystems.io
This article shows how to build a self-healing registry mirror on GKE with zot and automation that copies remote images locally and rewrites deployments to avoid Docker Hub rate limits and ImagePullBackOff failures.
Our Kubernetes Cluster Was Costing $14,850/Month. We Moved to Fly.io for $680.
levelup.gitconnected.com
This is a war story about a 3-person startup that replaced a $14,850/month over-engineered Kubernetes setup on AWS with Fly.io for $680, cutting P99 latency from 320ms to 180ms and deploy time from 8 minutes to 45 seconds.
Kubeshark: Making Packet Level Visibility in Kubernetes
anishkumarait.substack.com
This article explains how Kubeshark provides packet-level visibility in Kubernetes by capturing live pod traffic, decoding protocols such as HTTP and gRPC, and mapping requests back to workloads for debugging.
Running Temporal.io on Kubernetes in Production — What Nobody Tells You
medium.com
This article explains how to run Temporal on Kubernetes in production, covering GKE deployment, Cassandra repair and backups, Istio mTLS, resource sizing, PodDisruptionBudgets, and Prometheus-based monitoring.
What 6 Months of Tracking a Production OpenShift Cluster Revealed About Kubernetes Costs
blog.kubeledger.io
This article explains what six months of production OpenShift cost tracking revealed, including a 24 to 30 percent non-allocatable CPU tax and how infrastructure overhead can consume most cluster capacity before app workloads even start.
Orchestrating Secure AI Agents on Amazon EKS
dev.to
This case study shows how Unitary built Osmia, an open-source orchestration layer on EKS to run autonomous AI coding agents safely at scale using pod isolation, Karpenter, IRSA-based secrets, and real-time trajectory scoring.
Some LearnKube projects are too large to make alone
We want to keep creating ambitious technical education for Kubernetes and platform engineering teams.

Tutorials
LLMs on Kubernetes: The Easy Way
pittar.medium.com
This tutorial shows how to run an open source LLM on OpenShift with Red Hat AI Inference Server based on vLLM, using a PVC, GPU-backed deployment, OpenAI-compatible endpoint, model switching, and an optional AnythingLLM UI.
Kubernetes Gateway API on EKS Exposed via ALB
dev.to
This tutorial shows how to set up Kubernetes Gateway API on EKS using Istio Ambient Mesh exposed through AWS ALB, with Terraform, ArgoCD, and a layered architecture separating infra from app deployment.
Designing an Elastic Kubernetes Platform on VMware vSphere with Cluster API and Cluster Autoscaler
msyawalsaputra.medium.com
This tutorial teaches how to build an elastic Kubernetes platform on VMware vSphere using Cluster API, Talos, and Cluster Autoscaler for declarative provisioning and automatic node scaling.
What happens when an AI agent stops generating Kubernetes YAML and starts operating the cluster directly?
Mike Solomon, software engineer at AIATELLA, explains how his team moved from a sprawling Helm setup to Markdown-driven infrastructure specs that Claude Code can execute, test, and refine.
You will learn
- Why Helm became hard to maintain for a fast-moving medical infrastructure repo
- How Claude debugged Argo, TLS conflicts, kubectl patches, and private registry credentials
- How runbooks plus agent memory files capture failures so deployments become reproducible.
It is a practical look at where Kubernetes automation may be heading: less hand-written YAML, more precise intent, and a sharper definition of when the human must stay in the loop.
