Hi All, When I worked on MESOS-9231 <https://issues.apache.org/jira/browse/MESOS-9231>, I found the way that we run the `docker inspect` command seems not correct, we'd better specify `--type=container` for it, otherwise, `docker inspect` may return an object which is not a container (e.g., a volume).
So I posted a patch <https://reviews.apache.org/r/68872/> to add `--type=container` to the `docker inspect` command. However I found Docker started to support `--type=container` from 1.8.0, but our minimal supported Docker version is 1.0.0 (see here <https://github.com/apache/mesos/blob/1.7.0/src/docker/docker.cpp#L152> for details). I think it does not make sense for us to support Docker 1.0.0 which is too old, so I propose to update the minimal supported Docker version in Mesos to 1.8.0. Please let me know for any comments, thanks! Regards, Qian Zhang
