from flask import Flask

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)

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

You need to add a proc file to run Flask app on cloud foundry. Please follow this link - https://github.com/swisscom/cf-sample-app-python

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
