Hello, Please bear with me since I am not that very docker savvy. As far as I understand, normally, one can expose certain ports in a docker description file. But, how to do that when using `guix pack -f docker` command where the docker recipe is hidden from the user?
Also, I note I'm getting ~10 GiG image for a flimsy program depending on R and shiny. Somehow that doesn't feel right. :)
