title: Unable to connect to dockerized redis instance from outside docker
body: <p>I have the latest docker installation (without boot2docker) and I am unable to connect to a dockerized redis instance running locally. Could you please tell me what I'm doing wrong here?</p>
  
  <p><strong>Created the docker, mapped port 6379 to 127.0.0.1:6379</strong></p>
  
  <pre><code>bash-3.2$ docker run -p 127.0.0.1:6379:6379  --name webmonitor-redis -d redis
  3291541d58ab16c362f9e0cd7017d179c0bc9aef3a1323e79f1e1ca075e171c9
  </code></pre>
  
  <p><strong>docker ps output:</strong></p>
  
  <pre><code>bash-3.2$ docker ps
  CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                      NAMES

  </code></pre>
  
  <p><strong>Tried connecting from outside container (but the same host where container is running), connection failed:</strong></p>
  
  <pre><code>bash-3.2$ ./src/redis-cli
  Could not connect to Redis at 127.0.0.1:6379: Connection refused
  not connected&gt; exit
  </code></pre>
  
  <p><strong>It works if I try to connect from another container though..</strong></p>
  
  <pre><code>bash-3.2$ docker run -it --link webmonitor-redis:redis --rm redis sh -c 'exec redis-cli -h "$REDIS_PORT_6379_TCP_ADDR" -p "$REDIS_PORT_6379_TCP_PORT"'
  172.17.0.8:6379&gt;

  <p><strong>Here's the docker inspect for the container:</strong></p>
