Subject [jira] [Created] (MESOS-3740) LIBPROCESS_IP not passed to Docker containers
Date Wed, 14 Oct 2015 23:58:05 GMT
Cody Maloney created MESOS-3740:
-----------------------------------

             Summary: LIBPROCESS_IP not passed to Docker containers
                 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).
