Tasks will not launch on DC/OS OSS.

[javadevmtl]

Hi, so as sugested I tried the marathon example...

{
  "id": "/eremetic",
  "cpus": 0.5,
  "mem": 100.0,
  "instances": 1,
  "container": {
    "type": "DOCKER",
    "docker": {
      "image": "alde/eremetic",
      "network": "BRIDGE",
			"portMappings": [
				{
					"hostPort": 0,
					"containerPort": 8000,
					"servicePort": 0,
          "labels": {
            "VIP_0": "/eremeticdev:8000"
          },
          "name": "http"
				}
			],
			"forcePullImage": true,
      "privileged": true,
			"parameters": [
				{
					"key": "log-driver",
					"value": "none"
				}
			]
    }
  },
  "env": {
    "MASTER": "zk://zk-1.zk,zk-2.zk,zk-3.zk/mesos",
    "ADDRESS": "0.0.0.0",
    "PORT": "8000"
  }
}

But the tasks don't launch...

The DC/OS version works...

I think I was missing this...

{ "containerPort": 0, "hostPort": 0 }

I'm guessing that's to be able to access the scheduler and get offers.
