Simple Flask application for Cloud Foundry

Simple Python Flask app on Cloud Foundry

This is a (very) simple Flask application that shows how the built-in Python buildpack detection on Cloud Foundry works.

To push to Cloud Foundry, log in and then use

$ cf push myapp-name

Python on Cloud Foundry

Cloud Foundry: http://cloudfoundry.org

  • Python is a first class language
  • Deploy with cf push myapp
  • Scale with cf scale myapp ...

You can try Cloud Foundry by signing up for a free trial at Pivotal Web Services.

from flask import Flask
import os
app = Flask(__name__)
port = int(os.getenv("PORT"))
@app.route('/')
def hello_world():
return 'Hello World! I am running on port ' + str(port)
if __name__ == '__main__':
app.run(host='0.0.0.0', port=port)
web: python hello.py

Anybody got troubles? I get "ERR Uploading failed" while doing cf push. (uploading droplets failed)

Per flasks own docs the built in server is for development, and is not suitable for production. Instead should be handled by one of the methods described http://flask.pocoo.org/docs/1.0/deploying/#deployment
