Running a Kubernetes Cluster at Home
Kubernetes at home is divisive. For many self-hosters, Docker Compose is genuinely enough. But if you want to learn the platform that runs most of the modern internet — and you are willing to invest a weekend — a home cluster is one of the best classrooms there is.
When it makes sense
- You are preparing for a CKA/CKAD certification.
- You manage Kubernetes professionally and want a safe lab.
- You genuinely have 20+ self-hosted services and want declarative config.
If none of the above apply, stay on Docker Compose. There is no shame in that.
Distribution choice
- k3s — single binary, perfect for one to three nodes. Our default recommendation.
- k0s — similar to k3s, slightly different defaults.
- Talos — immutable OS, beautiful, slightly more advanced.
Avoid full upstream Kubernetes at home — it is a lot of moving parts for no real benefit.
Hardware
Three mini-PCs (N100 class) with 16 GB RAM each gives you a real multi-node cluster for under the price of a single gaming GPU. Add a NAS for persistent storage via NFS or Longhorn.
What to actually run
- Traefik or Nginx Ingress for routing
- cert-manager + Cloudflare for automatic TLS
- ArgoCD or Flux for GitOps
- Longhorn or Rook-Ceph for storage
- Prometheus + Grafana + Loki for observability
The honest tradeoff
A home cluster will eat one weekend a month for the first six months while you learn it, then almost no time after that. Budget accordingly.
If you would like Rustyt to design or audit a home — or production — Kubernetes estate, start a conversation.
