Provide working example for VIP routing

[meichstedt]

Please provide a working example (tutorial/deep dive) for VIP routing

This may be integrated into the DC/OS docs, but it should at least be a part of the Marathon documentation.

An example of a deep dive can be found here: mesosphere-backup/dcos-docs#66

Note: this should be done by eod 04/15

  "cpus": 1,
  "mem": 128,
  "disk": 0,
  "instances": 1,
  "container": {
    "docker": {
      "image": "python:2.7-alpine",
      "network": "BRIDGE",
      "portMappings": [
        {
          "containerPort": 80,
          "protocol": "tcp",
          "name": "http",
          "labels": {
            "VIP_0": "192.168.0.100:80"
          }
        }
