Creating a user-defined overlay network
While the ability to create your own bridge is certainly appealing, your scope is still limited to that of a single Docker host. The overlay network Driver aims to solve that by allowing you to extend one or more subnets across multiple Docker hosts using an overlay network. Overlay networks are a means to build isolated networks on top of existing networks. In this case, the existing network provides transport for the overlay and is often named the underlay network. The overlay Driver implements what Docker refers to as multi-host networking.
In this recipe, we'll learn how to configure the prerequisites for the overlay Driver as well as deploy and validate overlay-based networks.
