As long as you are pulling images from a docker registry, this should automatically happen.

Ya the point is it won't have access to a registry. I would like to be able to ship docker "packages" that have everything they need, but not have a lot of duplicate data (the base os image) in each package. I should be able to have the base image as its own package for example, and the other packages just have the "diff" files that they need.
Last I checked. Docker will pull a delta when resolving new containers, but will export the entire thing if you want something for offline usage.

I had the same question as OP and didn't find anything that works as he described it when I looked 6+ months ago.
