The Kubernetes project that vSphere with Tanzu Supervisor Cluster uses to automate the lifecycle management of Tanzu Kubernetes Grid Clusters is Cluster API. Cluster API is a Kubernetes project that provides declarative APIs for cluster creation, configuration, and management. Cluster API uses a set of custom resource definitions (CRDs) to represent clusters, machines, and other objects. Cluster API also relies on providers to implement the logic for interacting with different infrastructure platforms5. vSphere with Tanzu Supervisor Cluster uses Cluster API to deploy and manage Kubernetes clusters on vSphere 7 across multiple vCenter Server instances and/or multiple data centers via Tanzu Mission Control6.
