Inter docker communication (mqtt and python) - docker

Question

I am having two docker containers in IBM Bluemix. One is MQTT and other php-python.
The PHP application executes a python script that should connect to the MQTT docker container and subscribe to a topic.
However, the php-python docker fails to connect. It also fails to ping to the MQTT docker container.
The MQTT container is working perfect as I am able to connect to it from my local machine.
I have tried linking the two containers using the following command:
cf ic run -p 443 -p 80 --name connector --link moscacontainer:source
registry.ng.bluemix.net/fortspace/php-mqtt
I have exposed the ports 1883 and 80 for the MQTT container.
I have used the following link as reference:
https://github.com/dceejay/nrdock/blob/master/README.md#linking-containers
Can someone guide on this?
EDIT: The output for cf ic inspect

You can review information in this page:
https://console.ng.bluemix.net/docs/containers/container_linking.html
I am afraid the the --link is incorrect and you will may have to ensure alias and name are correct.
This command output should help you:
cf ic inspect recipient_container_name
