Kubernetes Virtual Clusters
summary
Creates a self‑contained Kubernetes control plane inside one namespace by running k3s in a pod (api server + storage) and a synchronizer that copies/renames pods, services and ingresses into the host namespace; uses the vcluster CLI and Helm for provisioning. Demonstrates different API versions (host 1.21, virtual 1.24), shows kyverno policy enforcement installed in the virtual cluster that blocks pod creation without readiness/liveness probes, and uses scale-to-zero to free resources; overhead is small (runs on Raspberry Pi / <1GB).
