Opencv on Openshift

When I wanted to intall opencv on my python-2.7 openshift online cartridge I faced the problem of quota limitation to 1GB.
I found this blog post by Stephen Nneji discussed how to use DIY cartridge and install python and opencv manually. Another blog post by Nikhil Kumar used the Python-2.7 cartridge template to reduce the size of compiled opencv.
I collected the complete steps and put them in a single bash script.

To run this script in your openshift Python-2.7 cartridge, run the following command:

$ wget https://raw.githubusercontent.com/ammarnajjar/opencv_on_openshift_online/master/install.sh && bash install.sh

Then test importing opencv:

> python
Python 2.7.11 (default, Mar 31 2016, 20:46:51) 
[GCC 5.3.1 20151207 (Red Hat 5.3.1-2)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
>>>
