How to Build a Multi-Context Lab for Kubernetes
summary
Builds a local multi‑context Kubernetes lab with Vagrant and the Ubuntu-k8s box from a provided repo, creating three clusters (bk s, hk s, wk s) with configurable worker counts and switchable kubeconfigs that merge per‑master kubeconfigs into one console file. Demonstrates changing Kubernetes versions and scaling workers, claims it runs reliably in demos, and recommends a minimum of 16 GB RAM for the host. Setup uses Vagrant and reproducible Vagrantfiles; the demo works end‑to‑end.
