I can't speak for Red Hat specifically (ethics concerns) but Atomic, Red 
Hat's bare-bones distribution based upon RHEL has docker 1.2. Atomic 
will move faster then RHEL and likely have  the first upgrade to docker 
1.3.  Knowing the RHT workflow, I expect a rebase of docker will hit 
RHEL 7 at some point in the near future, but I don't know the specific 
schedules.
