Docker Hub Group permissions

As part of a story in a recent development iteration at work, I found myself guiding two development teams in the use of Docker Hub.

Strangely my current project had already had an indirect dependency on Docker Hub for a few months, but today was the first time that we actually needed to consider the ins and outs of this particular system.

In this case the "in" side involves our continuous deployment system pushing an image, and the "out"side involves a separate system pulling an image from the same repository.

In the interests of ensuring that each project team does not run the risk of accidentally blowing away anything or everything that the other project teams have set up, I took it upon myself to learn the ins and outs of group permissions in Docker Hub.

Now instead of just having one big group of Owner users associated with our organisation we have two additional groups for my current project - one that contains users with the right to push images, and one with the right to read (pull) images.
