Kubernetes-in-Kubernetes with Kamaji, KubeVirt, and the Cluster API
summary
Implements Cluster API on bare metal using a single management Kubernetes cluster called Cozy Stack and proves tenant clusters run reliably: Kamaji control plane as pods manages API server/controller/scheduler lifecycle, while KubeVirt VMs for workers provision machines via Cluster API machine deployments; Flux CD delivers Helm charts and tenant components; LinStore + a CSI passthrough provides dynamic PV provisioning; OVN handles L2/L3 routing and Cilium-style network policies enforce tenant isolation; cluster autoscaler and updates work end-to-end.
