service designed by the CoreOS team for kubernetes, which simply means that the Docker container created by the different node hosts in the cluster has a unique virtual IP address for the complete cluster. It also creates an overlay network between these IP addresses, which, through this overlay network, passes the packets intact to the target container (Overlay).Here is a schematic diagram of its network:As you can see,
