Python3 app using cf tasks

README.md

Push an app

Push an app with a main web process that runs forever (in this case it does nothing) and there is no healthcheck

Download main.py, http-call.py, and requirement.txt into a directory. Then from that directory, run:

cf push py-simple -b https://github.com/cloudfoundry/python-buildpack.git -c "python main.py"  -u none

Once the app is pushed, you can tail the logs

cf tail -f py-simple

Run a task

Then you can run a task using any other python file that is bundled with the app, like http-call.py:

cf run-task py-simple "python http-call.py"

In the logs, you should see the status of the request print out

2019-04-08T21:27:10.22-0600 [APP/TASK/744dbd64/0] OUT https://pivotal.io STATUS 200

http-call.py

from urllib import request

if __name__ == "__main__":
    with request.urlopen("https://pivotal.io") as response:
        print("https://pivotal.io STATUS {}".format(response.status))

main.py

import time

if __name__ == "__main__":
    while True:
        time.sleep(10)
