             Summary: Capture and report docker issues as part of mesos-master logs.
                 Key: MESOS-2790
                 URL: https://issues.apache.org/jira/browse/MESOS-2790
             Project: Mesos
          Issue Type: Improvement
          Components: docker
    Affects Versions: 0.22.1
         Environment: CentOS 7 x86-84
            Reporter: Casey Sybrandy


I just ran into an issue today where docker ran into an error where it couldn't update it's iptables chain.  (It was missing for some reason.)  It took a while to debug the problem because as far as mesos was concerned, there were no errors.  Executing the container simply failed.

To try to make it easier to know what's going on, is it possible for the mesos slaves to capture any docker errors and report them as part of the mesos master log?  Even better would be if it could report the error via the UI.  At a bare minimum, and only if you can't nicely capture the docker error, report that a docker error has occurred and which machine it occurred on.
