Ideally atomic will be able to run multiple container runtimes. In and effort to do so, we must have a concept of a global registries configuration file which will allow us to pull images with atomic and skopeo. The tooling that parses the global configuration file is: https://github.com/projectatomic/registries This is step one in the implementation of this tooling and direction.
