Docker -p hostPort:containerPort in mesos 0.20.0

[Javier Ruiz Jiménez]

Hi All

I am translating all our Marathon API calls to new format for Marathon
0.7.0-SNAPSHOT
as we have upgraded to Mesos 0.20.0.

I used to map some container ports to well known host ports.

Example from when using Deimos:

 "options" : ["-p","9000:9000"]

Following Marathon upgrade guide in
https://mesosphere.github.io/marathon/docs/upgrade/06xto070.html

{
  "container": {
    "image": "docker:///megacorp/product:1.2.3",
    "options": [
      "-v", "/var/data/a:/etc/a:ro",
      "-v", "/var/data/b:/etc/b:rw",
      "-e", "FOO=bar",
      "-p", "443:443"
    ]
  }
}

Gets translated to:

{
  "container": {
    "type": "DOCKER",
    "docker": {
      "image": "megacorp/product:1.2.3"
    },
    "volumes": [
      {
        "hostPath": "/var/data/a",
        "containerPath": "/etc/a",
        "mode": "RO"
      },
      {
        "hostPath": "/var/data/b",
        "containerPath": "/etc/b",
        "mode": "RW"
      }
    ]
  },
  "env": {
    "FOO": "bar"
  },
  "ports": [443],
  "requirePorts": true
}

But if I do the same, docker ps shows no port mappings for the container.
No ports are mapped.

Any suggestions?
How can I see the "docker run command " that mesos executes?

Thanks,
Javier
