ROS 2 and Kubernetes
Apart from plain LAN-to-LAN communication, Cloud environments such as container-oriented platforms have also been present throughout the DDS Router design phase. In this walk-through example, we will set up both a Kubernetes (K8s) network and a local environment in order to establish communication between a pair of ROS nodes, one sending messages from a LAN (talker) and another one (listener) receiving them in the Cloud. This will be accomplished by having a DDS Router instance at each side of the communication.
