As it is said in the text before "The example bind-mounts `/mnt/registry` on the swarm node to `/var/lib/registry/` within the container." the example uses a bind-mount instead of a volume-mount (see difference here in the docs: https://docs.docker.com/engine/swarm/services/#give-a-service-access-to-volumes-or-bind-mounts). As bind-mounts are only applied with `type=bind` configuration parameter of `--mount`, it has to be added here so that the `swarm-registry` service is able to start. Additionally, the bind-mount relies on the pre-existing src-directory `/mnt/registry`, which should also be added to the documentation - see important notes "If you bind mount a host path into your service’s containers, the path must exist on every swarm node." in https://docs.docker.com/engine/swarm/services/#give-a-service-access-to-volumes-or-bind-mounts.

…/1)"-error, see docker/docs#4641 We need to configure the bind-mount in the --mount configuration parameters of docker service create command, as the docs state. Also added constraint to only replicate registry on Linux nodes and created `/mtn/registry` directory on all Linux nodes.
