Sign Up Heroku
we need to sign up Heroku to use heroku service. signup and signin Heroku to click the link below.
- Heroku: https://heroku.com/
I won’t mention how to sign up and sign in Heroku service because it is a normal process to use the service.

we need to create Heroku App for Heroku web service.
after signing-up and signing-in, you can see the (Dashboard) screen like below. click Create new app to create new app.
insert an app information to create Heroku app. it’s free so we can make United State and Europe region only. if you’ve done, click Create app butotn.
Install Heroku CLI
we’ll use Heroku CLI(Command Line Interface) to upload(Deploy) our django project to Heroku. click the link below to download Heroku CLI for each OS. in this blog, I will use macOS.
- download Heroku CLI: https://devcenter.heroku.com/articles/heroku-cli
on macOS, execute the command below to install Heroku CLI.
brew tap heroku/brew && brew install heroku
Login Heroku
for deploying a web service to Heroku, we need to login to Heroku via Heroku CLI. execute the command below to login Heroku service.
heroku login
after executing the Heroku command above, you can see the login screen on the browser. click Log in button.
after login, you can see the login success screen like below,

Modify django Project
we’re ready to deploy to Heroku service. however, we need to modify our django project to work on Heroku service. create Procfile to the folder that has manage.py file and modify it like below.
web: gunicorn django_exercise.wsgi --log-file -
in above, you should modify django_exercise.wsgi to your project name([project name].wsgi). we notice guniconr that is python HTTP server(Python WSGI HTTP Server) on Heroku service to Heroku.
execute the command below to install modules to use django on Heroku service.
# source venv/bin/activate
pip install gunicorn whitenoise django-heroku
- gunicorn: this is python HTTP server(
Python WSGI HTTP Server). - whitenoise: this module is for django uses static files on Heroku.
- django-heroku: this module helps django settings simply for Hreoku.
after installing, execute the command below to update requirements.txt.
pip freeze > requirements.txt
after updateing, open and modify django_exercise/settings.py like below.
...
import django_heroku
...
DEBUG = False
ALLOWED_HOSTS = ['127.0.0.1', '.herokuapp.com']
...
MIDDLEWARE = [
'whitenoise.middleware.WhiteNoiseMiddleware',
...
]
...
# Activate Django-Heroku.
django_heroku.settings(locals())
and, store everything to our git.
git add .
git commit -m 'prepare to deploy'
git push origin master
Deploy(Upload)
we’ve done. let’s deploy django project on Heroku. execute the command below to add Heroku to git remote.
heroku git:remote -a djangoexercise
execute the command below to check Heroku added well.
git remote -v
you can see Heroku added in git remote like below.
heroku https://git.heroku.com/djangoexercise.git (fetch)
heroku https://git.heroku.com/djangoexercise.git (push)
origin https://github.com/dev-yakuza/django_exercise.git (fetch)
origin https://github.com/dev-yakuza/django_exercise.git (push)
execute the command below to deploy.
git push heroku master
Heroku is based on git for deployment. our django project is already deployed by the command above. now, we need to configure the database by our migration and create new administrator account for django. execute the command below to configure the database.
heroku run python manage.py migrate
execute the command below to make django administrator.
heroku run python manage.py createsuperuser
Check
let’s check our django project deployed on Heroku. execute the command below to open our site on the browser.
heroku open
we can see our django proejct deployed well like below.
add /admin to URL to go to the admin page.
and login with superuser we’ve created above.
we can see Post Model we’ve made before.
