[jira] [Created] (MESOS-4823) Implement port forwarding in `network/cni` isolator

Avinash Sridharan created MESOS-4823:
----------------------------------------

             Summary: Implement port forwarding in `network/cni` isolator
                 Key: MESOS-4823
                 URL: https://issues.apache.org/jira/browse/MESOS-4823
             Project: Mesos
          Issue Type: Task
          Components: containerization
         Environment: linux
            Reporter: Avinash Sridharan
            Assignee: Avinash Sridharan
            Priority: Critical


Most docker and appc images wish ports that micro-services are listening on, to the outside world. When containers are running on bridged (or ptp) networking this can be achieved by installing port forwarding rules on the agent (using iptables). This can be done in the `network/cni` isolator. 

The reason we would like this functionality to be implemented in the `network/cni` isolator, and not a CNI plugin, is that the specifications currently do not support specifying port forwarding rules. Further, to install these rules the isolator needs two pieces of information, the exposed ports and the IP address associated with the container. Bother are available to the isolator.
