Managed forwarding element executing in separate namespace of public cloud data compute node than workload application

摘要

Some embodiments provide a method for a network controller that manages a logical network implemented in a datacenter having forwarding elements to which the network controller does not have access. The method identifies a data compute node (DCN) operating on a host machine in the datacenter, to attach to the logical network. The DCN has a network interface with an address provided by a datacenter management system. A workload application executes in a first namespace of the DCN. The method distributes configuration data for configuring a managed forwarding element (MFE) executing in a second namespace of the DCN to receive data packets sent from the application via an interface pairing between the first and second namespaces. The data packets sent by the application have the provided address as a source address when received by the MFE and are encapsulated by the MFE using the provided address as a source address.
