Deploying a Python application to IBM Bluemix

The following simple example shows how to push the basic hello world Python application to IBM Bluemix. We use the buildpack below.

https://github.com/heroku/heroku-buildpack-python.git

1. Create a file called requirements.txt

pas@pass-mbp:~/bluemix-apps/python-demo$ cat requirements.txt
Flask==0.10.1


2. Create a file called runtime.txt to detail the Python version to use

pas@pass-mbp:~/bluemix-apps/python-demo$ cat runtime.txt
python-2.6.5


3. Push the application using the buildpack above.

pas@pass-mbp:~/bluemix-apps/python-demo$ cf push pas-phython-demo -m 128m -b https://github.com/heroku/heroku-buildpack-python.git
