vCluster creates tenant clusters: fully isolated environments delivered as managed Kubernetes, or as the foundation for Slurm, Ray, Run:ai and inference clusters. Each gets its own API server, CRDs and RBAC, and runs on an existing cluster or standalone on bare metal. CNCF Certified Kubernetes.
vCluster in Docker (vind) is KinD (Kubernetes in Docker) alternative with additional features. For source code, see loft-sh/vcluster repo linked below.
