Abstract: A network controller deploys network management applications to containers hosted on compute nodes. For each container on each compute node, the controller determines the network connectivity required by the application; assigns to the container one or more Internet Protocol (IP) addresses that satisfy the network connectivity, and provides the one or more IP addresses to the container; upon detecting the container is lost, blocks the one or more IP addresses so that the they cannot be re-assigned to any other container; and upon detecting that the application has been re-deployed to a new container on a new compute node, unblock the blocked one or more IP addresses, and assign and send the one or more IP addresses to the new container to enable the new container to establish the network connectivity required by the application without network address translation.

Abstract: A network device is configured to establish a messaging bus with a container networking plug-in, which is associated with a container virtual network. The network device is also configured to obtain, via the messaging bus, networking information for one or more containers hosted at the at least one container-hosting computing device. Based on the networking information, the network device provides visibility of one or more containers below the network device.
