KubeVela is widely used to build Control Plane of a Multiple-Tenancy Cloud platform. Its terraform k8s operator component Terraform Controller provides the capabilities to manage cloud resources with HCL manifest and it fetches back the terraform outputs back to CRDs' status for higher layer k8s operators to further reconcile the states.
