Looking for feedback from anyone, especially @npateriya.

I will add one more sample/example in that folder, for example mysql tcp load balancing, assuming below is right you can add same or fix it before adding. This will make shipped team clear on shipped related use case:

{
  "container": {
    "type": "DOCKER",
    "docker": {
      "image": "mysql",
      "network": "BRIDGE",
      "portMappings": [
        {
          "containerPort": 3306,
          "protocol": "tcp"
        }
      ]
    }
  },
  "id": "shipped-api-mysql",
  "instances": 1,
  "cpus": 1,
  "mem": 1024,
  "ports": [0]
  "env": {
    "MYSQL_ROOT_PASSWORD": "*****",
  }
}

yeah, that looks right to me. "ports": [0] is implicit when you don't set that field, but you're right that it should be explicit here.
