'moby run' will use the kernel and initrd image produced by 'moby build' and, on macOS, will run it inside a hyperkit VM. This assumes that you have a recent version of Docker for Mac installed as it re-uses the hyperkit and VPNKit from it. Signed-off-by: Rolf Neugebauer <rolf.neugebauer@docker.com>
