Get IP + port from boo2docker

If you use boot2docker you met the problem with port numbers too :) I'm on Mac and it's a huge issue for me to find my needed port number of a specified container.

Here is a script to get it as an URL (good for binding webservers).

#!/bin/bash

if [[ -z $2 ]]; then
  echo "Usage: $0 <conatiner> <port>"
  exit;
fi

echo `boot2docker ip 2>/dev/null`:`docker port $1 $2 | sed -e 's/.*://g'`

It has echo but my real script contains open like:

#!/bin/bash

if [[ -z $2 ]]; then
  echo "Usage: $0 <conatiner> <port>"
  exit;
fi

open "http://"`boot2docker ip 2>/dev/null`:`docker port $1 $2 | sed -e 's/.*://g'`"/"

It's good on mac because it's open the URL automatically in my browser. I put it into my ~/.bin/dockerport and I added this path to my PATH env variable, so I can run it as a normal "program".

Most of time I give a name to my containers so I can give that name instead of the Container ID.
