> Mesos Agent in docker neglects to retry discovering Task docker containers
> --------------------------------------------------------------------------
>
> Key: MESOS-8158
> URL: https://issues.apache.org/jira/browse/MESOS-8158
> Project: Mesos
> Issue Type: Bug
> Components: agent, containerization, docker, executor
> Affects Versions: 1.4.0
> Environment: Windows 10 with Docker version 17.09.0-ce, build afdb6d4
> Reporter: Charles Allen
> Priority: Major
>
> I have attempted to launch Mesos agents inside of a docker container in such
> a way where the agent docker can be replaced and recovered. Unfortunately I
> hit a major snag in the way the mesos docker launching works.
> To test simple functionality a marathon app is setup that simply has the
> following command: {{date && python -m SimpleHTTPServer $PORT0}}
> That way the HTTP port can be accessed to assure things are being assigned
> correctly, and the date is printed out in the log.
> When I attempt to start this marathon app, the mesos agent (inside a docker
> container) properly launches an executor which properly creates a second task
> that launches the python code. Here's the output from the executor logs (this
> looks correct):

> For some reason it seems like the AGENT is trying to connect to the TASK
> docker container in addition to the executor container, and is failing to
> find it and instantly dying instead of obeying a retry mechanism. I do not
> have an environment setup to trace the code path of this error state, but the
> expected behavior is either that the Agent leaves it to the executor to track
> the task, or that the agent respects retries. Neither of which seem to be
> happening here.
