The "UCR" (aka mesos containerizer) and "Docker containerizer" are two different containerizers that users tend to choose between. UCR is what many of our serious users rely on and so we made the investment there first. GPU support for the docker containerizer was also something that was planned, but hasn't been prioritized: https://issues.apache.org/jira/browse/MESOS-5795
These days, many of our users use Docker images with UCR (i.e. bypassing the need for the docker daemon). Maybe the containerization devs can chime in here I'm in saying anything inaccurate or to shed some light on where things are headed.
