How to get executor ports in container netns?

[Marc Roos <M....@f1-outsourcing.eu>]

I have this environment variable 
MESOS_AGENT_ENDPOINT='192.168.10.114:5051' that gives me the 5051 port, 
how can I get the 192.168.10.114:37722 and 192.168.122.146:36313 so I 
can use them in iptables rules?

Eg. Are they available in variables, so I can parse them via the labels 
networks configuration?
"networks": [ 
    { "mode": "container", "name": "cni-apps","labels": {"EXECPORT1": 
"XXX"} }
  ],
