Deploying a Service on an Overlay Network
Bridge networks are a powerful tool for controlling communication between containers on a single host, but what if you need to provide isolated networking between containers in Docker Swarm? With Docker Swarm, you can use custom overlay networks to allow groups of containers to communicate transparently, even if they are running on different swarm nodes.
In this lab, you will have the opportunity to work with overlay networks. You will set up a custom overlay network and deploy three different services that communicate with each other using this network.
