Deploying a Django application to Elastic Beanstalk AWS 502 Bad Gateway

Question

I follow all the instructions on the official AWS website, but I still get the same error. I have tried several projects, each on the local server works quite normally as soon as it starts on AWS I get the next error 502 Bad Gateway.

this seams like main problem : ModuleNotFoundError: No module named 'ebddjango/wsgi'

wsg file:

import os from django.core.wsgi 
import get_wsgi_application 
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'ebddjango.settings') application = get_wsgi_application()

config:

option_settings: 
aws:elasticbeanstalk:container:python: 
WSGIPath: ebddjango/wsgi:application

Status:

Please edit your answer and show me your config file and if is possible your ebddjango/wsgi.py file — Luiz, Jan 27 '22 at 18:18

Seems I had exactly the same problem: I was following the official tutorial but it was ending up with a 502 error. I found my solution on here, where they said:

It's true that Python 3.7+ on Amazon Linux 2 platform needs gunicorn.

So what I did was simply running the following command just after installing django (point 3 of the Set up a Python virtual environment and install Django section of the tutorial)

pip install gunicorn

In your .config file try

option_settings:
  aws:elasticbeanstalk:application:environment:
    DJANGO_SETTINGS_MODULE: ebddjango.settings
  aws:elasticbeanstalk:container:python:
    WSGIPath: ebddjango.wsgi:application
  aws:elasticbeanstalk:environment:proxy:staticfiles:
    /static: static

Alot of things can throw this error, but it can be your settings file that is not setting for production as here https://stackoverflow.com/questions/70332515/elastic-beanstalk-django-app-deployment-502-bad-gateway-server-not-running-no-m or you can be zipping your files wrong, you should zip your files not your folder as says here https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/applications-sourcebundle.html or it can be differences between python versions https://stackoverflow.com/questions/62479386/no-module-named-application-error-while-deploying-simple-web-app-to-elastic-be – Luiz Jan 27 '22 at 21:12
I tested with a completely empty django project . 2 times I went through comand promt, starting the project of everything and pushing on AWS 502. after that I went with zipping and uploading via aws console, each time the result was the same 502. Thank you for good input i will cheek setings.py file to see whats happening in there , it may be the issue with not for depployement settings . – Nemanja Pavlovic Jan 28 '22 at 07:59
