This document discusses Docker networking strategies in Swarm, Mesos, and Kubernetes orchestration tools. It provides an overview of early Docker networking methods like bridge, host, and container modes as well as the newer libnetwork approach. The document outlines PLUMgrid's involvement in the Docker ecosystem through their libnetwork plugin and work with Mesos networking. It concludes with an agenda for a demo of Docker Swarm with network creation using libnetwork and PLUMgrid virtual distributed services for container micro-segmentation and security policies.
