This is what we do on the tripleo undercloud using the image-serve
service[0]. We have python code that extracts the layers out and
writes it to disk[1][2] which makes it effectively a read only
registry.  Though the amount of code to do all this is terribly
complex and I wouldn't recommend doing it for anything else.  If you
can use the docker-registry via a container[3], that'd likely be a
better solution if you can (though may not be possible for various
reasons).
