Forward container ports to the host

[unwiredbrain]

Please, add the ability to automatically forward the exposed ports to the host.

Let's say I'm using dockerfile/elasticsearch. Its Dockerfile exposes ports 9200 and 9300.

Here's the Vagrantfile I'm using:

# -*- mode: ruby -*-
# vi: set ft=ruby :

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.define "elasticsearch" do |es|
    es.vm.provider "docker" do |container|
      container.image = "dockerfile/elasticsearch"
      container.ports = [ "9200:9200", "9300:9300" ]
      container.remains_running = true
    end
  end
end

On the boot2docker guest everything is fine

docker@boot2docker:~$ curl -sS -X GET http://127.0.0.1:9200/
{
  "status" : 200,
  "name" : "Sleepwalker",
  "version" : {
    "number" : "1.1.1",
    "build_hash" : "f1585f096d3f3985e73456debdc1a0745f512bbc",
    "build_timestamp" : "2014-04-16T14:27:12Z",
    "build_snapshot" : false,
    "lucene_version" : "4.7"
  },
  "tagline" : "You Know, for Search"
}

But no port is forwarded to the host

Am I missing something?

[unwiredbrain]

Forgot to mention:

• Windows 7 x64
• VirtualBox 4.3.12r93733
• Vagrant 1.6.2
• Cygwin 2.850 x64 (Bash 4.1.11-2, rsync 3.0.9-1)

I also tried setting up a host-only interface and use that instead, but still no luck

config.vm.network "private_network", ip: "10.0.0.10"

$ curl -sS -X GET http://10.0.0.10:9200/
curl: (7) Failed connect to 10.0.0.10:9200; No error

• VMWare Fusion 6.0.4
• Vagrant 1.6.5
