If you are creating a docker image for just a
package, why not just use `guix pack` on top of a
host image(like say alpine) or something similar?
I reckon it's more straightforward imho--- I've
had to do that before. Here are the docs:
https://github.com/genenetwork/genenetwork2/blob/testing/doc/docker-container.org. You
could just substitute the genenetwork2 package
with your package! ;)

HTH!
