Kamaji
What Kamaji is
Kamaji runs Kubernetes control planes as pods in a management cluster, giving platform teams a way to operate multiple tenant clusters. Tenant control planes work independently, with separation between tenants. The project uses upstream Kubernetes components and kubeadm, and its tenant clusters are CNCF conformant. Worker nodes can run on bare metal, virtual machines, or cloud instances. Cluster API integration supports infrastructure provisioning and lifecycle management. Datastores include etcd and MySQL- or PostgreSQL-compatible databases through kine; NATS support is experimental. Konnectivity, enabled by default, creates secure tunnels between tenant control planes and worker nodes. Kamaji exposes Prometheus-format metrics for both management and tenant control planes. By default, manager and kubeconfig-generator metrics endpoints use unauthenticated plaintext, though documentation describes an option for HTTPS and bearer-token authentication. The software collects usage data about its version and tenant control planes, with an opt-out setting. The Kamaji Open Source plan costs nothing under Apache 2.0. Clastix offers subscription enterprise support, including SLA-based ongoing engineering support and one-off deployment assistance.
