The new Driver in 1.12 is MacVLAN. MacVLAN is a performant driver designed to allow the Docker network to plumb to the existing VLAN, for example, a corporate one, letting everything to continue to work. There is a scenario where we will gradually migrate workloads from the original VLAN to Docker and MacVLAN will help plumb the Docker cluster to the original VLAN. This will make the Docker networks integrated with the underlay network and the containers will be able to work in the same VLAN.

We could just create a network with the MacVLAN driver and specify the real subnet to the network. We can also specify a range of IP addresses only for the containers. Also, we can exclude some IP addresses, for example, the gateway, from assigning to containers with --aux-address. The parent interface of the MacVLAN driver is the interface we would like to connect this network to. As previously mentioned, MacVLAN yields the best performance of all drivers. Its Linux implementation isextremely...
