I have two files app.py which is in root and the init.py inside a directory named website.
error log:

I am hoping someone can help. I have been trying to launch my flask app on ubuntu. The app runs on dev mode, but when I try to run it with gunicorn, I get the following error:

Here is my app.py file

app.run(debug=True)
Here the site structure.

Can someone help?

I found the issue. Had to move the app=create_app above the 'if' statement.
Is there a way to start CKAN 2.9 with gunicorn?
I can see from the documentation that gunicorn is mentioned:
Install Supervisor (a Process Control System) used to control
starting, stopping the uwsgi or gunicorn servers:
But not much information is in there.
Since 2.9 is flask I was looking at how to serve a flask application with Gunicorn an I came across this post: How To Serve Flask Applications with Gunicorn and Nginx on Ubuntu 18.04 and I tried by using this code (wsgi.py):
import os
from ckan.config.middleware import make_app
from ckan.cli import CKANConfigLoader
from logging.config import fileConfig as loggingFileConfig
app = None
if __name__ == "__main__":
config_filepath = os.path.join(os.path.dirname(os.path.abspath(__file__)), 'ckan.ini')
abspath = os.path.join(os.path.dirname(os.path.abspath(__file__)))
loggingFileConfig(config_filepath)
config = CKANConfigLoader(config_filepath).get_config()
app = make_app(config)
Then running:
gunicorn --bind 0.0.0.0:5000 wsgi:app
But I get:
[2022-06-22 20:09:34 +0000] [365] [INFO] Starting gunicorn 20.1.0

Any idea is appreciated

While running docker-compose up it gives the following log
But running docker logs originor-nginx it gives nothing
Somewhere in your 'web' initialization you must call manage.py collectstatic to put static files of application in your volume. More info https://docs.djangoproject.com/en/2.1/howto/static-files/

I was following a tutorial at https://ashokfernandez.wordpress.com/2014/03/11/deploying-a-django-app-to-amazon-aws-with-nginx-gunicorn-git/
on deploying a django application. This is my current situation:
fab spawn instance created the aws instance with nginx and gunicorn installed but when I tried accessing the site on that machine I got a 400 Bad Request. I checked the nginx-error log but that was empty and the nginx-access log showed that it had received the requests. The supervisor log had the following:

I changed ALLOWED_HOSTS from [] to ["*"] and then '*'
When I changed it to the string, I got "The requested URL / was not found on this server." On other instances, I got 400 bad request.
This is the first time I am deploying a django app on nginx and I can’t figure out what the problem might be. Could you please help me debug this error?
Thanks in advance!!
PS: Please let me know if I need to post any config files. So far I have just followed the tutorial and I have not changed any configurations.

The allowed hosts has to match the host names you'll be using. So put the ALLOWED_HOSTS = [] in a settings file specific to your environment (Dev or production). On the dev side set it to ALLOWED_HOSTS = ['localhost', '127.0.0.1'] and on production set it go your domain & server IPs.
From the docs:
Values in this list can be fully qualified names (e.g. 'www.example.com'), in which case they will be matched against the request’s Host header exactly (case-insensitive, not including port). A value beginning with a period can be used as a subdomain wildcard: '.example.com' will match example.com, www.example.com, and any other subdomain of example.com. A value of '*' will match anything; in this case you are responsible to provide your own validation of the Host header (perhaps in a middleware; if so this middleware must be listed first in MIDDLEWARE_CLASSES).
The status 400 response you get is due to a SuspiciousOperation exception being raised when your host header doesn't match any values in that list.
I am trying to run my django app using gunicorn and foreman. I can successfully run it using python manage.py server. However when running it using forman it fails -

Below is the contents of the Procfile -
web: gunicorn tms.wsgi
I have been following the instructions given on heroku for setting it up.
What instructions are you following? I run Django apps on Heroku using this:
web: python django_project/manage.py run_gunicorn -b "0.0.0.0:$PORT" -w 3 -k gevent --preload
What directory is your settings.py file located in in which you added 'gunicorn' to your INSTALLED_APPS? I'm assuming you're following the Heroku Getting Started with Django tutorial. The .wsgi file you state in your Procfile should match with that directory which you have your settings.py in.
Your Procfile should be:
web: gunicorn <directory_containing_settings.py_file>.wsgi -b 0.0.0.0:$PORT
If you are facing trouble following the Heroku Documentation then you may check my sample app deployed to Heroku https://github.com/shinigamiryuk/Django-Heroku-Sample-Application
