Moving an RHSCL app to Docker on Atomic

As many of you have probably heard, Red Hat announced a new “Docker server” at Summit. The new server is called “Atomic” and details can be found at the project home page. As you all know, I tend to be interested in using Software Collections to ensure the portability of applications. So, putting my foot^W money where my mouth is, I decided to download Atomic, run it as a VM, create a Docker image with a Software Collection, and copy a previous app there, unchanged. The pros and cons of running an application as a Docker container are debated heavily elsewhere, so we won’t discuss the “why” (unless you tell us we should in the comments 🙂 ), just the “how.”
