Run real KVM virtual machines as Kubernetes resources on k3s. One control plane for pods and VMs, no more juggling Proxmox alongside your cluster every day.

Open Policy Agent and Gatekeeper enforce rules across Kubernetes, block privileged pods, require labels, restrict images. Rego basics and real homelab constraints.

Two ways to give your K8s cluster persistent block storage, Longhorn for simplicity, Rook-Ceph for scale. Real homelab tradeoffs, not vendor marketing slides.

Ingress is the annotation-soup classic. Gateway API is the role-oriented future with proper L4/L7 separation. Here's when to migrate and when to wait.

Your cluster will fail. Velero captures everything, manifests, CRDs, persistent volumes, and lets you replay it on a fresh cluster. Setup, gotchas, real DR plans.

Kustomize patches YAML with overlays. Jsonnet is a real templating language with imports and functions. Here's which K8s manifest tool to pick.

cert-manager makes Let's Encrypt automatic on Kubernetes, once. Then you scale, hit DNS-01 quirks, wildcard limits, and rate-limit walls. Here's the full survival guide.

Argo Rollouts uses a Rollout CRD with a slick UI. Flagger watches your Deployment with a Canary CRD. Here's which progressive-delivery tool to pick.

Two Kubernetes-native pipeline engines from CNCF, Argo Workflows and Tekton. Different philosophies, same goal: stop using Jenkins. Honest comparison.

kubeadm is the official Kubernetes bootstrapper. k3sup is a one-shot SSH installer for k3s. Here's which one to use for your homelab cluster.

etcd powers Kubernetes. Consul is the service-discovery Swiss army knife. ZooKeeper is the grizzled veteran. Here's how to pick a coordination store.

Alpine gives you a shell and apk; Distroless gives you nothing but the app. Compare attack surface, image size, and multi-stage build complexity.
