Looking through the updated "Getting Started with Django on Heroku" guide, they have the following example procfile:
web: gunicorn hellodjango.wsgi --log-file -
What does the --log-file - mean?
It means "log to stdout". The --log-file flag lets you set a path to a log file, and - means "stdout" (in this context).

I need to add Gunicorn parameter --timeout 600. Where should I add it? My project contains a Procfile, server.py and Jupyter notebook and requirements.txt.
Your Procfile defines process types for Heroku to run. Yours likely contains a line like this:
web: gunicorn hello:app
This tells Heroku that you have a web process that can be started by running gunicorn hello:app. If you want to pass an argument to gunicorn, modify that line accordingly:
web: gunicorn hello:app --timeout 600
Commit that change and redeploy.
So I'm doing a university group project and we are demonstrating tomorrow. It's a flask API and I'm hosting with Heroku. At first I got this error
code=H14 desc="No web processes running"
After looking around I found a solution to scale dynos with :
heroku ps:scale web=1
Which in turn failed, resulting in this error
Couldn't find that process type (web)
I have no idea what is going wrong. My Procfile is named correctly and updated (no .txt at the end). Any help would be greatly appreciated.
My Procfile:
web:gunicorn api_prediction:medi-ai
Where "api-prediction" is the python file to run and "medi-ai is the project name"
Example for the Procfile
#filename: Procfile
web: gunicorn runserver:app --log-file=-
Example for the gunicorn
# filename: run.gunicorn.sh
gunicorn -b :5000 --access-logfile - --error-logfile - runserver:app
Also install gunicorn and dont miss the requirements.txt file too.
pip install gunicorn
pip freeze > requirements.txt
If this doesn't resolved your issue please reply.
My current app is running in my local environment and has the following in its Procfile: web: gunicorn hellodjango.wsgi --log-file -
I'm looking for a way to change this so that foreman restarts itself upon each web request so I don't have to do so every time I make a code change.
I know it's been a while since this question but I've just realised I asked a similar question yesterday.
The solution is to add the --reload option to gunicorn. So your Procfile will look like:
web: gunicorn --reload hellodjango.wsgi --log-file -
Can somebody help me regarding on how can i solve my problem on Heroku. Im new to Heroku.
This warning always appear. WARNING:No Procfile detected, using the default web server (webrick). Im using Rails 4. Thank in advance
The error itself is pretty self-explanatory. No Procfile is detected, so in your root directory create a file called Procfile.
As you stated in your comment you are using the Unicorn server so inside the Procfile put this code.
web: bundle exec unicorn -p $PORT -c ./config/unicorn.rb
I am assuming you created a unicorn.rb file
push to github, push to heroku and see if that works.
The Procfile holds the command for starting the server, and any options you need to pass to that. Your app was crashing because the command to start the server was not there at all.
I'm trying to install New Relic, but it says I'll need to make changes to Procfile. I can't seem to find it at the root of the local copy of my app though. I'm using Django.
Thanks
This page on Heroku gives a lot more information on what the procfile is:
https://devcenter.heroku.com/articles/procfile
You don't have to have one to deploy to Heroku, but you can manually create one to take more control over how Heroku runs your apps. As per this excerpt from the link above:
A Procfile is not necessary to deploy apps written in most languages supported by Heroku. The platform automatically detects the language, and creates a default web process type to boot the application server.
Creating an explicit Procfile is recommended for greater control and flexibility over your app.
For Heroku to use your Procfile, add the Procfile to the root of your application push to Heroku:
$ git add .
$ git commit -m "Procfile"
$ git push heroku
...

For New Relic support, you have to explicitly tell Heroku to run a gunicorn instance within New Relic. So your Procfile would look something like this:
newrelic-admin run-program gunicorn --workers 4 --worker-class gevent --timeout 60 mysite.wsgi
You can turn this on or off without changing your Procfile by conditionally looking for your New Relic licence in the Heroku environment variables:
Procfile:
web: bash scripts/heroku_run
scripts/heroku_run:
#!/bin/bash
run_command="gunicorn --workers 4 --worker-class gevent --timeout 60 mysite.wsgi"
# Run through New Relic monitoring if add-on installed
if [[ $NEW_RELIC_LICENSE_KEY != '' ]]; then
newrelic-admin run-program $run_command
else
$run_command
