Setting up a python-flask application on IDA openshift

• Pre-requisite: Install rhc tool
  If you get dependency problems installing rhc try this:
  • gem install rubygems-update
  • update_rubygems
  • gem install rhc
• First setup your account on openshift.ida.liu.se:
  rhc setup -l liu-id --server openshift.ida.liu.se
  Follow the instructions on openshift for setting up your machine:
  Linux
  Mac
  Windows
  
• Create a python application:
  rhc create-app flask python-2.7
• Check out your application (sometimes create-app checks out the application in which case next step is not necessary):
  rhc git-clone flask(accept the RSA fingerprint)
• Edit setup.py (this so openshift knows to install Flask for your application)
  For know it should look like this:

  from setuptools import setup
  
  setup(name='YourAppName',
        version='1.0',
        description='OpenShift App',
        author='Your Name',
        author_email='example@example.com',
        url='http://www.python.org/sigs/distutils-sig/',
        install_requires=['Flask'],
       )
  

• Add , commit and push your edited file:
  git add setup.py
git commit -m "Added flask for install" setup.py
  Push your changed file to openshift
  git push
  
• Create the flask server-file server.py it should look something like this:
  

  from flask import Flask
  app = Flask(__name__)
  
  @app.route("/")
  def hello():
      return "Hello World!"
  
  if __name__ == "__main__":
      app.run()
  

• Add, commit and push your server.py:
  git add server.py
git -m "initial server" server.py
git push
• Edit wsgi.py
  

  #!/usr/bin/python
  import os
  
  virtenv = os.environ['OPENSHIFT_PYTHON_DIR'] + '/virtenv/'
  virtualenv = os.path.join(virtenv, 'bin/activate_this.py')
  try:
      execfile(virtualenv, dict(__file__=virtualenv))
  except IOError:
      pass
  #
  # IMPORTANT: Put any additional includes below this line.  If placed above this
  # line, it's possible required libraries won't be in your searchable path
  #
  from server import app as application
  

  (Remove everything else in the file)
• Add, commit and push your edited
  git add wsgi.py
git commit -m "import app from server.py"
git push
  
• Go to your web application to see that everything is working:
  To find the URL to your application use:
  rhc show-app flask
