[~tnachen] Sorry for the radio silence. Do you have capacity to take this on/shepherding?

>          Issue Type: Bug
>          Components: containerization, docker
>    Affects Versions: 0.25.0

> Docker containers aren't currently passed all the same environment variables that Mesos Containerizer tasks are. See: https://github.com/apache/mesos/blob/master/src/slave/containerizer/containerizer.cpp#L254 for all the environment variables explicitly set for mesos containers.
> While some of them don't necessarily make sense for docker containers, when the docker has inside of it a libprocess process (A mesos framework scheduler) and is using {{--net=host}} the task needs to have LIBPROCESS_IP set otherwise the same sort of problems that happen because of MESOS-3553 can happen (libprocess will try to guess the machine's IP address with likely bad results in a number of operating environment).
