title: Docker container port issue
body: <p>I've installed docker on raspbian jessie 8 (IP 192.168.2.2) . I created a docker container with raspbian base image with minecraft installed on in. I opened the port 25565 on the container</p>
  
  <pre><code>pi@raspberrypi ~ $ docker run -d -p 25565:25565 rpi_minecraft
  
  pi@raspberrypi ~ $ docker ps
  CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                              NAMES

  <p>When I attempt to see if that port is opened I get this error </p>
  
  <pre><code>Andrews-iMac:~ Andrew$ telnet 192.168.2.2 25565
  Trying 192.168.2.2...
  telnet: connect to address 192.168.2.2: Connection refused
  telnet: Unable to connect to remote host
  </code></pre>
  
  <p>What is causing this issue? All the relevant ports look open to me?</p>
