Flask Application not starting up, server says HTTP 500 - deployment

Question

My flask app is in $OPENSHIFT_REPO_DIR/repo directory with files as
..repo$ ls
runserver.py app.py
and my app.py looks like
def run_simple_httpd_server(app, ip, port=8080):
from wsgiref.simple_server import make_server
make_server(ip, port, app).serve_forever()
if __name__ == '__main__':
ip = os.environ['OPENSHIFT_INTERNAL_IP']
port = 8080
from runserver import run
run_simple_httpd_server(run, ip, port)
while runserver.py looks like
from configuration import app
from core.expense import expense
from core.budget import budget
def run():
app.register_blueprint(budget)
app.register_blueprint(expense)
app.run()
When I restart my app, I do not see anything happening
\> ctl_app restart
when I hit the url in browser it says
A server error occurred. Please contact the administrator.
I do not even see the logs anywhere, what is that I am doing wrong here?
I am doing the deployment for the very first time

Answer 1

How are you deploying your flask application? Are you using the Flask example on github: https://github.com/openshift/flask-example ?
Overall, you shouldn't be required to start your app from ssh on the gear as our start/stop hooks should handle that. Give the flask-example a try. Otherwise, you can review your logs to troubleshoot your 500 error:

Answer 2

I had to call my application from app.py, I did following and got my app running
cd ~/app_root/repo
vi app.py
# change last part of file to
# you need to do every time code is pushed via git push
if __name__ == '__main__':
ip = os.environ['OPENSHIFT_INTERNAL_IP']
port = 8080
from runserver import run
run(ip, port)
# restart app
ctl_app restart
and my runserver.py looks like
def run(host, port):
from configuration import app
app.run(host=host, port=port)
