Spinning-up a Development Instance on OpenShift

Difio is hosted on OpenShift. During development I often need to spin-up another copy of Difio to use for testing and development. With OpenShift this is easy and fast. Here's how:

1. Create another application on OpenShift. This will be your development instance.

   rhc-create-app -a myappdevel -t python-2.6
   

2. Find out the git URL for the production application:

   $ rhc-user-info
   Application Info
   ================
   myapp
       Framework: python-2.6
        Creation: 2012-02-10T12:39:53-05:00
            UUID: 723f0331e17041e8b34228f87a6cf1f5
         Git URL: ssh://723f0331e17041e8b34228f87a6cf1f5@myapp-mydomain.rhcloud.com/~/git/myapp.git/
      Public URL: http://myapp-mydomain.rhcloud.com/
   

3. Push the current code base from the production instance to devel instance:

   cd myappdevel
   git remote add production -m master ssh://723f0331e17041e8b34228f87a6cf1f5@myapp-mydomain.rhcloud.com/~/git/myapp.git/
   git pull -s recursive -X theirs production master
   git push
   

4. Now your myappdevel is the same as your production instance. You will probably want to modify your database connection settings at this point and start adding new features.
