Yubo Li commented on MESOS-5799:
--------------------------------
docker 1.9.1 and mesos master branch synced yesterday.
> docker::inspect() may get wrong output when a docker container is not in
> "running" state
> ----------------------------------------------------------------------------------------
>
> Key: MESOS-5799
> URL: https://issues.apache.org/jira/browse/MESOS-5799
> Project: Mesos
> Issue Type: Bug
> Components: containerization, docker
> Reporter: Kevin Klues
> Assignee: Benjamin Mahler
> Labels: containerizer, docker
> Fix For: 1.0.0
>
>
> I (klueska) am copying the text from an email I got about a bug report from
> Yubo Li at IBM.
> docker::inspect() may get wrong output when the docker container is not in
> "running" state. In this case, the "docker inspect" will failed to parse
> data, and system can not enter TASK:RUNNING status.
> I attached related logs in stderr, I printed the docker inspect output. The
> inspected output shows that the docker is in "created" status, not "running",
> so that many of inspect fields are invalid.
> Possible Fix: detect the "State->Running" field, and get success return when
> "State->Running" is true.
