Create fully functional virtual Kubernetes clusters with vcluster. 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. vcluster itself is a certified Kubernetes distribution and is 100% Kubernetes API conform. Everything that works in a regular Kubernetes cluster works in cluster. Pods are scheduled in the underlying host cluster, so they get no performance hit at all while running. Split up large multi-tenant clusters into smaller vcluster to reduce complexity and increase scalability. Since most vcluster api requests and objects will not reach the host cluster at all, vcluster can greatly decrease pressure on the underlying Kubernetes cluster. Create via vcluster CLI, helm, kubectl, Argo or any of your favorite tools (it is basically just a StatefulSet).
Features
- Much cheaper than "real" clusters (single pod and shared resources just like for namespaces)
- Can be created and cleaned up again in seconds (great for CI/CD or testing)
- More powerful than simple namespaces (virtual clusters allow users to use CRDs etc.)
- Allow users to install apps which require cluster-wide permissions while being limited to actually just one namespace within the host cluster
- Complete separate Kubernetes control plane and access point for each vcluster while still being able to share certain services of the underlying host cluster
- Allow you to test different Kubernetes versions inside a single host cluster which may have a different version than the virtual clusters
