Abstract: Techniques are disclosed for a unified control plane in a nested cluster environment. In one example, an underlay orchestrator for a virtualized computing infrastructure is configured to provision, in an underlay cluster of one or more servers, an overlay cluster of one or more overlay nodes. Each of the overlay nodes is a workload of one of the servers and has a virtual network interface. Further, each server executes a virtual router and a virtual router agent for the virtual router for routing packets among virtual network interfaces of the overlay nodes executed by the server. A network controller is configured to configure virtual network sub-interfaces for workloads of the overlay nodes to enable communications among workloads executing in different overlay nodes. Each of the sub-interfaces is a virtual network sub-interface of one of the virtual network interfaces.

Abstract: Techniques are described for creating multiple virtual network interfaces usable by a logically-related group of one or more containers (“pod”) for communicating on respective virtual networks of a network infrastructure. In some examples, a control flow for pod network interface configuration on a host includes obtaining, by a CNI instance, a list of multiple virtual network interfaces from an agent of a network controller that is executing on the host. The single CNI instance processes the list of multiple virtual network interfaces to create corresponding virtual network interfaces for the pod and, for each of the virtual network interfaces, to attach the virtual network interface to the pod and to the virtual router or bridge for the host. In this way, the single CNI enables packetized communications by containers of the pod over multiple networks using the multiple virtual network interfaces configured for the pod.
