---------------------------------
Hi, [~cmaloney] A little thing I could not understand here, in which case, we
need pass LIBPROCESS_IP to docker containers? Because only
mesos-docker-executor would communicate with agent and docker container is
managed by mesos-docker-executor. Seems the docker containers not need know
LIBPROCESS_IP here. Or you refer to launch a seperate docker container to run
the executor when we specify docker_mesos_image flag?

> 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
> Assignee: Michael Park
> Labels: mesosphere
>
> 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).
