             Summary: Add version member field to Docker class to avoid validate docker version every time
                 Key: MESOS-6064
                 URL: https://issues.apache.org/jira/browse/MESOS-6064
             Project: Mesos
          Issue Type: Improvement

Now the minimum docker version we supported is >=1.0.0. However, we support some advanced features after docker 1.0.0 as well which require {{Docker::validateVersion}} before use them. {{Docker::validateVersion}} is a blocking function which waits for {{docker --version}} return. Call it too many times bring unnecessary overheads. It would be better that we add a member field represent current docker version in {{Docker}} class to avoid to execute {{docker --version}} every time.
