--------------------------------------
[~greggomann]
trying to understand this issue as we hit this issue very often.
do we need docker inspect just for the pid of the newly launched container?
wondering if there is an alternative to 'docker inspect' if its just pid.
> Docker executor makes no progress when 'docker inspect' hangs

> In the Docker executor, many calls later in the executor's lifecycle are
> gated on an initial {{docker inspect}} call returning:
> https://github.com/apache/mesos/blob/bc6b61bca37752689cffa40a14c53ad89f24e8fc/src/docker/executor.cpp#L223
> If that first call to {{docker inspect}} never returns, the executor becomes
> stuck in a state where it makes no progress and cannot be killed.
> It's tempting for the executor to simply commit suicide after a timeout, but
> we must be careful of the case in which the executor's Docker container is
> actually running successfully, but the Docker daemon is unresponsive. In such
> a case, we do not want to send TASK_FAILED or TASK_KILLED if the task's
> container is running successfully.
