>                 Key: MESOS-3740
>                 URL: https://issues.apache.org/jira/browse/MESOS-3740
>             Project: Mesos
>          Issue Type: Bug
>          Components: containerization, docker
>    Affects Versions: 0.25.0
>         Environment: Mesos 0.24.1
>            Reporter: Cody Maloney

> 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).
