<p>Docker daemon accepts <code>--bip</code> argument to configure the subnet of the docker0 bridge. It also accepts <code>--mtu</code> to set the MTU for docker0 and veth devices that it will be creating. Since flannel writes out the acquired subnet and MTU values into a file, the script starting Docker can source in the values and pass them to Docker daemon:</p>
