vCluster - Create fully functional virtual Kubernetes clusters - Each vcluster runs inside a namespace of the underlying k8s cluster. It's cheaper than creating separate full-blown clusters and it offers better multi-tenancy and isolation than regular namespaces. observed · 2026-08-28

vCluster is an open-source tool that creates fully functional virtual Kubernetes clusters, each running inside a namespace of an underlying host cluster, providing stronger multi-tenancy and isolation than plain namespaces at lower cost than separate full clusters. It has evolved into a broader tenant cluster platform for AI infrastructure, supporting managed Kubernetes, Slurm, and inference clusters on shared nodes, private nodes, or bare metal via its vMetal machine API.
Use cases
- run isolated virtual kubernetes clusters inside a shared host cluster
- give each team or customer their own kubernetes control plane without provisioning full clusters
- build a multi-tenant kubernetes platform for internal teams or external customers
- spin up ephemeral kubernetes clusters for local development and CI with Docker
- offer self-service managed kubernetes on GPU infrastructure for AI workloads
- achieve kubernetes multi-tenancy beyond namespaces with isolated API servers and RBAC
- turn bare metal GPU servers into a cloud platform with tenant clusters
When to choose
- you need hard isolation between tenants on a shared kubernetes cluster
- creating separate full clusters per team or customer is too expensive or slow
- you are building an AI cloud, GPU cloud, or platform-engineering offering with self-service clusters
- you want a CNCF-certified kubernetes experience with your own API server, CRDs, and RBAC per tenant
When to avoid
- simple namespaces with RBAC and resource quotas are sufficient isolation for trusted internal teams
- you have no kubernetes cluster or infrastructure to host virtual clusters on
- you need a fully managed hosted kubernetes service rather than self-operated tooling
- your workloads are tiny and the overhead of a virtual control plane is not justified
