Spotlight

Jack Lindamood

This case study shows how OOM Killer terminated a critical network daemon on Kubernetes nodes, causing a network outage.

It covers debugging via serial console and implementing memory reservations to prevent system-critical process termination.

Build a Production-Ready vLLM Inference Server on Kubernetes with AMD Instinct GPUs
Ojas Singh
This tutorial teaches how to run a production-ready vLLM inference server on Kubernetes with AMD Instinct GPUs using containerd, the AMD GPU Operator, persistent storage, and MetalLB.
Why Kubernetes Has No Login — And How We Solved It for AuditRadar
hybrid2k3
This article explains why vanilla Kubernetes has no real login event and shows a practical session-tracking workaround using credential-id fingerprints from audit logs, with a side-by-side comparison against OpenShift OAuth behavior.
Designing for Failure with CloudNativePG
Dylan Da Costa
This tutorial explains how to design CloudNativePG for production failure by using plugin-based backups, WAL archiving, point-in-time recovery, snapshots, and PgBouncer so recovery is treated as the real operational priority.

Tools and utilities

Kappal
Kappal runs your existing docker-compose.yaml on Kubernetes using familiar commands like up, down, logs, exec.
Kubie – isolated per-shell Kubernetes context and namespace manager
Kubie is a tool that provides an alternative to kubectx, kubens, and the k on prompt modification script, offering context switching, namespace switching, and prompt customization.
Harbor
Harbor is a CNCF-graduated open source container registry that stores, signs, and scans images, with built-in RBAC, LDAP/OIDC support, vulnerability scanning, policy-based replication, and a full REST API.
Zeropod: scale to zero
zeropod is a tool that automatically checkpoints containers to disk after a certain amount of time of the last TCP connection, allowing for fast and seamless scaling down to zero.
Yoke: WASM IaC deployer
Yoke is an IaC tool inspired by Helm that leverages WebAssembly and Go to dynamically deploy Kubernetes packages with executable runtime capabilities.

Three Weeks in the Trenches: Hunting a 4GB Native Memory Leak That .NET Couldn’t See
Kalyan Josyula
This case study shows how a team traced repeated pod OOM kills in ASP.NET Core to native memory growth from zombie SignalR connections, glibc fragmentation, and kernel socket buffers.
Autoscaling Hid Our LLM Cost Regression (85% → 4% Cache Hit Rate)
Nick Roan
This case study shows how a single RAG chunk size change collapsed vLLM prefix-cache hit rate from 85% to 4%, triggering an 80% GPU replica increase while latency stayed flat.
It also includes the fix: adding a two-phase cache replay gate in CI.
How My Client Hit Linux Kernel Network Limits on AWS EKS
Dat Ton
This case study explains how cURL 65 errors and DNS resolution failures on AWS EKS were caused by Linux kernel network limits being exceeded, resolved by increasing netdev_budget, netdev_budget_usecs, and netdev_max_backlog parameters.
Orchestrating Secure AI Agents on Amazon EKS
Matt Camp
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.
