--------------------------------

             Summary: Port mapper CNI plugin should use '-n' option with 'iptables --list'
                 Key: MESOS-9129
                 URL: https://issues.apache.org/jira/browse/MESOS-9129
             Project: Mesos
          Issue Type: Improvement
    Affects Versions: 1.6.1
            Reporter: Greg Mann


Without the {{-n}} option, [this iptables command|https://github.com/apache/mesos/blob/9457dce1d99b5616d1b5eeb9a344733f6320d7b5/src/slave/containerizer/mesos/isolators/network/cni/plugins/port_mapper/port_mapper.cpp#L313] could result in a large number of reverse hostname lookups, which could take a while.

We should use the -n option there to avoid this issue.
