Installing packages from satellite in Docker

Dear all,

I have read in the announcement of satellite blog that it was mentioned that there is some docker integration work with Satellite.
I wonder how this will be done, and also if this would change anything regarding RedHat satellite fees.

Is there any workaround to install packages within a docker container ? Despite, creating a distinct yum repository ?
I know Docker may not be supported yet, but it's time to test and play with it.
