Inditex Tech
This case study shows how Inditex reclaims idle node capacity with an open-source overcommit operator that rewrites pod requests through a mutating webhook, based on priority class.
Ryan Waite
This case study follows one engineer building a home data centre from scratch, running k3s on recycled hardware with NAS storage, Cloudflare Tunnels for public access and Argo CD for deployments.
This article digs into a bug in VPC CNI v1.21.0 in which a reused loop variable wrote network policy rules to the wrong eBPF map, silently dropping every packet to the pod.
Abhi
This tutorial shows how to build a local Kubernetes lab in Vagrant where MetalLB actually works, by giving each VM both a host-only and a bridged network.
Tools and utilities
Hermes Agent Operator runs Hermes AI agents on Kubernetes as custom resources, so each agent's config, skills and workspace live in one manifest instead of drifting on someone's laptop.
System Upgrade Controller upgrades your nodes from inside the cluster: you describe the change in a Plan resource and it runs the upgrade job on each node, cordoning and draining when you ask it to.
Jarvis is a self-hosted web UI for Alertmanager where alerts are stored in a database, and people can claim and comment on them so the team sees who is handling what.
Kubernetes production readiness checklist is a free, open checklist for taking applications to production on Kubernetes, covering app design, manifests, security, scaling and going live.
Attune is a Kubernetes operator that monitors actual usage and adjusts CPU and memory requests for running pods in place, so nothing has to restart.

This case study shows how one team ran LiteLLM as a single gateway to many model providers on EKS, kept it highly available, and managed the whole thing with ArgoCD.
Anastassios Nanos
This case study shows how etcd CrashLoopBack pods on a Karmada/k3s demo cluster turned out to be a ZFS I/O latency problem, and how four ZFS tuning settings fixed it — including the exact etcd Prometheus metrics to watch.
