There appears to be some sort of total character limit for at least the
following commands performed in the Dockerfile MAINTAINER, LABEL, ENV, CMD
(These are what I have tested against).
This is not an actual restriction of Docker. The images launch just fine in
Docker when manually invoking docker run from a Mesos slave.
I have attached two Dockerfiles, one that is a single character below this
limit and works and another that is a single character above this limit and
does not work.
