             Summary: local docker puller fails to find private registry repositories
                 Key: MESOS-5009
                 URL: https://issues.apache.org/jira/browse/MESOS-5009
             Project: Mesos
          Issue Type: Bug
          Components: containerization, docker
            Reporter: James Peach
            Priority: Minor


If you use the unified containerizer and the local docker puller with a Docker image from a private registry, the local puller fails to find any layers in the image's repository manifest.

For example, the image's {{repository}} file looks like this:

{code}
$  cat repositories
{"docker-registry.foo.com/image":{"latest":"c6c35f224e926912cb61ddc48b36376c65806378432b9cbb895e10a17a99b49d"}}
{code}

There's 2 problems that prevent this working. First, the local puller needs to check {{reference.registry()/reference.repository()}} as well as {{reference.repository()}}. Second, in {{JSON::Object::find}}, the dot is treated specially so we need to just index the top level object keys.
