[jira] [Created] (MESOS-1762) Avoid docker pull on each container run

Timothy Chen created MESOS-1762:

             Summary: Avoid docker pull on each container run
                 Key: MESOS-1762
                 URL: https://issues.apache.org/jira/browse/MESOS-1762
             Project: Mesos
          Issue Type: Improvement
            Reporter: Timothy Chen
            Assignee: Timothy Chen


Currently the docker containerizer does a docker pull on each run, and this has several downsides:

1. Not able to run local images
2. Require to contact registry server on each run, therefore docker run becomes unavailable if the registry server is down. Also has scalability limits.

We want to avoid doing a pull everytime. The downside ofcourse is that images without explicit tags (:latest) will not get the most updated version, but this is the same behavior when calling docker run on the cli.
