During the PoC phase, our only networking-related requirement was to have all of the nodes on the same network, and a network configuration that would allow for a free flow of traffic between the nodes.

Introduction to Docker single-node networking
While single-node networking may seem like an oxymoron, in the early days of Docker, many containers would run on a single node. Additionally...
