@ChetanBhasin Hi Sorry we know we are terribly behind on schedule. We got pulled into some internal projects and couldn't spend time on this recently. We will try and get upto speed in completing these open issues.

This framework is built on top of 'mesos-go' language binding. This language binding is pending update since some time, for VIP support the protobuf message specification should be upgraded. The current spec does not cover 'Labels' portion which is important in setting VIP. https://github.com/mesos/mesos-go/pull/263/files#diff-a9294dbaba0cf94ca6b1772f84ca5e9bR537. Long story short for us to be able to use VIP these changes to be pulled into master mesos/mesos-go#263.

Hey! What about the service port ? Is there any way to define the service port of the redis master instance in order to contact it with marathon-lb ?
Example:
Definition: portMappings: [ { "containerPort": 6380, "hostPort": 0, "servicePort": 10001 } ]

Reachable with: marathon-lb.marathon.mesos:10001
