loft-sh/vcluster
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.
Build with Backblaze B2
SDKs, agent skills, IDE extensions, and reference pipelines from Backblaze Labs. All open source.

Use Cases & Benefits
- Creates fully functional virtual Kubernetes clusters inside namespaces of a host cluster or standalone on bare metal, each with its own API server and isolated environment.
- Enables flexible multi-tenancy with strong isolation and resource syncing while leveraging shared platform infrastructure to reduce overhead and costs.
- Use for providing isolated, managed Kubernetes environments to GPU cloud customers with fast provisioning and production-grade security.
- Use for running multi-tenant AI/ML workloads on-premises with dedicated or private nodes to maximize GPU utilization and compliance.
- Use for deploying Kubernetes-native software with isolated virtual clusters per customer, enabling secure multi-tenancy and simplified operations.

From the README
Flexible Tenancy For Kubernetes and AI Infra
vCluster creates fully functional virtual Kubernetes clusters that run inside namespaces of a host cluster. Each virtual cluster has its own API server, runs on shared or dedicated infrastructure, and gives you flexible tenancy options—from simple namespaces to fully dedicated clusters.
40M+ virtual clusters deployed by companies like Adobe, CoreWeave, Atlan, and NVIDIA.
Prerequisites: A running Kubernetes cluster and
kubectlconfigured.
