Kubernetes

Kubernetes guides for homelabbers and sysadmins — k3s, k8s, deployments, service mesh, and the operational parts that don't fit into a "hello world" tutorial.

  •   Install Kubernetes on Rocky Linux

    Three-node cluster from scratch — one master, two workers, containerd runtime, Calico CNI. End-to-end tested, paired with a YouTube walkthrough.

  •   Ingress on bare metal

    NGINX Ingress Controller in-cluster with HAProxy as the front-end load balancer. Real domains, clean URLs, no per-app cloud LB bill.

On the roadmap

  • cert-manager + Let's Encrypt — automatic TLS for everything behind Ingress
  • GitOps with Argo CD or Flux
  • Storage for Kubernetes — Longhorn, OpenEBS, Rook-Ceph, NFS-backed PVCs
  • k3s vs full k8s — picking the right distribution for a homelab
  • Cluster upgrades — moving from 1.28 → 1.29 → 1.30 without breaking things
