Error R10 (Boot timeout) : Django app on heroku - django

I have been trying to deploy a django app on Heroku. But it is always failing with the following error (R10 timeout, failed to bind to PORT in 60 seconds). The app works absolutely fine when deployed locally. I have been able to configure the postgres db correctly on heroku (bootstrapped the data and checked the contents). But somehow my web application is not starting, as can be seen in the logs below.
I have tried setting up explicit port number, as suggested in some forums. But it didn't work.
Any idea what's going wrong ?
I have put the heroku logs below. My code is here, if it helps : https://github.com/solitaryreaper/sp_mysiswrites
Thanks.

Change your Procfile according to documentation given on Heroku.
Also add gunicorn to INSTALLED_APPS in settings.py
your Procfile look like
"web: gunicorn path/of/yourwsgit/file.wsgi"
your wsgi script look like this.
import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings")
from django.core.wsgi import get_wsgi_application
from dj_static import Cling
application = Cling(get_wsgi_application())

Application error on deployed django rest framework app on heroku

I'm trying to deploy my django rest framework app on Heroku. I read many other similar questions but I'm confused. My app structure is not right or I'm missing something.
This is my structure on git:
.gitignore
requirements.txt
src
|
--authorization
--core
--static
--staticfiles
--Procfile
--manage.py
--suacm
|
---asgi.py
---settings.py
---urls.py
---wsgi.py
authorization and core are apps under my django project. there wasn't static or staticfiles before heroku deploy. But it automatically created staticfiles. Then I also created static and followed instructions to make it work via changes in settings.py. It'd be awesome if someone help me figure out my problem on heroku and why it doesn't work.
This is Procfile:
web: gunicorn suacm.wsgi
web: gunicorn suacm:app
When I run app with this command my app works fine and run locally:
gunicorn suacm.wsgi:application
But I couldn't solve the error in deployed app.
With
heroku logs --tail
I receive errors starts like below:
2021-05-21T14:32:20.000000+00:00 app[api]: Build succeeded

When I run this
heroku ps:scale web=1 --app suacm
I get this:
Scaling dynos... !
▸ Couldn't find that process type (web).
And finally when I try to run heroku locally under src folder with this command
src % heroku local web
I get this response:
[INFO] Starting gunicorn 20.1.0
[INFO] Listening at: http://0.0.0.0:5000 (35246)
[INFO] Using worker: sync
[INFO] Booting worker with pid: 35247

[INFO] Worker exiting (pid: 35247)
.
.
If needed, this is my requirements.txt file:
django_environ==0.4.5
djangorestframework_simplejwt==4.6.0
django_filter==2.4.0
Django==3.1.3
djangorestframework==3.12.4
environ==1.0
PyJWT==2.1.0
gunicorn==20.1.0
django-on-heroku==1.1.2
whitenoise==5.2.0
This is my first time deploying a django app. I hope I gave enough information. Just ask if there is more information needed.
Put your Procfile in the root directory, not in the src and
change this
web: gunicorn suacm.wsgi
to
web: gunicorn src.suacm.wsgi
Then why it work on a local server?
In your local setup, you are launching the server from the src directory which is not the root directory!
But the in the production Heroku launches the application from the root directory, since there is no Procfile in the root directory you are getting these errors.

Django site hosting on Heroku "No web processes runnng"

So I tried to host my Django application to Heroku and at first it worked. Then I wanted to add some release commands so I did this:
release_commands.sh
python manage.py makemigrations
python manage.py migrate
And in my Procfile:
release: bash ./release_commands.sh
web: gunicorn todo.wsgi --log-file -
The second line in my Procfile is unchanged, so I guessed that the error must be coming from the release commands, but that's not the case as in my heroku logs I have this:
2021-02-17T19:41:31.675215+00:00 heroku[release.6232]: Process exited with status 0
2021-02-17T19:41:31.772693+00:00 heroku[release.6232]: State changed from up to complete
2021-02-17T19:41:34.021990+00:00 app[api]: Release v11 created by user georgi.hr.dim#gmail.com
This is the error message:
2021-02-17T19:41:43.594322+00:00 heroku[router]: at=error code=H14 desc="No web processes running" method=POST path="/accounts/login/?next=/" host=essentialtodo.herokuapp.com request_id=5dce4816-6343-44c3-9c8f
-171e79379abc fwd="78.90.0.206" dyno= connect= service= status=503 bytes= protocol=https
Just found out what the problem was. For some reason after adding the release commands my dynos were turned off. To fix this: go to your heroku app (on the heroku website) -> go to resources -> press the edit button on your dyno -> turn it on and confirm
.

Docker + Django + PostgreSQL + Heroku = Failed to bind to $PORT within 60 seconds

So I am building a Dockerized Django project and I want to deploy it to Heroku, but I am having a lot of issues. My issues are exactly the same as this post:
Docker + Django + Postgres Add-on + Heroku
Except I cannot use CMD python3 manage.py runserver 0.0.0.0:$PORT since I receive an invalid port pair error.
I'm just running
heroku container:push web
heroku container:release web
heroku open
After going to the site it stays loading until it says an error occurred. My log shows the following:
System check identified no issues (0 silenced).

The app works locally through a virtual environment and using Docker but just not on Heroku. Not sure what else to try. You can find my code at: https://github.com/AlbMej/Online-Loan-Application
Maybe I have some glaring problems in my Dockerfile or docker-compose.yml
The Answer is not correct.
If you use container with Dockerfile, you do not need any Profile.
Just use the $PORT variable to let heroku to determine which port to use.
https://help.heroku.com/PPBPA231/how-do-i-use-the-port-environment-variable-in-container-based-apps
Quick solution is to change your Procfile to this:
web: python subfolder/manage.py runserver 0.0.0.0:$PORT
That would work, but keep in mind that you are using the development server on production, which is a really bad idea! But if you are just toying around, that's ok.
However, if you're using this as a production app with real data, you should use a real production server. Then your Procfile would look like this:
web: gunicorn yourapp.wsgi --log-file -

During deployment i get dozen of lines like the below, but i am not sure it has anythong to do with the problem:
Found another file with the destination path 'style.css'. It will be
ignored since only the first encountered file is collected. If this is
not what you want, make sure every static file has a unique path.
That's not how you use gunicorn. It accepts a Python module path, not a file path, and doesn't take an IP or port on the command line.
As the docs show, actually all you need is just:
web: gunicorn folder.wsgi
assuming folder is your project name.

heroku django webserver failed

I use Procfile with web: python manage.py runserver '0.0.0.0:$PORT' first time it started successfully, but after first git push it crashed with this error:
OperationalError at /

Is the server running on host "127.0.0.1" and accepting
TCP/IP connections on port 5432?
restarting webrunner did not help. What's the trick?

Using djangos' runserver at least started at first time. But then also got crashed.
I do not know the exact reason, but why are you running django's runserver on heroku? Heroku uses gunicorn, which can execute the .wsgi files in your project_name/project_name folder.
Instead, use: "web: gunicorn recipe.wsgi" in the procfile, so gunicorn serves your django app. Just my 2 cents.
Also, it seems if you use 0.0.0.0:5432 or 127.0.0.1:5432, it might work.
Your database is not connected. Make sure you set the proper DATABASE_URL environment variable, and that you actually have a postgres plan active.
Thanks #user2707389, it really works only with all apps declared in requirements.txt but I don't get it why it doesn't with -r option. Anyway, fixing further Procfile and correct wsgi.py made it alive.
