From Zero to Homelab
Networking → Docker → Kubernetes → Observability
How to go from a single machine to a self-operated infrastructure fabric. This is the path the homelab in the Digital Twin was built on.
Understand the network first
Before containers and clusters: subnets, VLANs, routing, and DNS. Everything that fails later fails here first — the twin models this layer explicitly.
Containerize with Docker
One machine, many isolated workloads. Compose files are the first taste of declarative infrastructure — and the habit that makes Kubernetes learnable.
Graduate to Kubernetes
k3s on bare metal, GitOps with Flux, distributed storage with Longhorn. The cluster reconciles itself from Git — you stop SSH-ing into servers.
Observe everything
Prometheus and Grafana turn the fabric from a black box into a system you can reason about. This is the same philosophy the Runtime OS projects onto the twin.
