# How to deploy your Django app to Heroku

Deploying a Django app to Heroku can be a walk in the park for some developers. But for some developers, it seems like they're going through a rough time when they're deploying their Django app. To tell you honestly, I also had a hard time deploying my first Django app in Heroku, but I managed to get through it after a while.

We only need 3 accounts, and if you haven't registered yet to Heroku, AWS & GitHub/GitLab, please do so to continue.

Cookiecutter-Django makes deployment to Heroku way too easy. All the commands are laid out on their documentation, and we don't even need to touch anything on our config/settings.py file. We're still able to deploy our app.

Make sure you commit your changes to GIt and have the Heroku CLI installed first. If you have it, then run.

```bash
$ heroku login
heroku: Press any key to open up the browser to login or q to exit:
After pressing any key, it'll take you to the login page of Heroku to login.
```

After logging in, you can go back to your command line and run these commands from the Cookiecutter-Django docs: https://cookiecutter-django.readthedocs.io/en/latest/deployment-on-heroku.html.

To gain more understanding of what these are, you can go and scan this page. https://cookiecutter-django.readthedocs.io/en/latest/settings.html

`$ heroku create --buildpack https://github.com/heroku/heroku-buildpack-python`

```bash
$ heroku addons:create heroku-postgresql:hobby-dev
# On Windows use double quotes for the time zone, e.g.
# heroku pg:backups schedule --at "02:00 America/Los_Angeles" DATABASE_URL
$ heroku pg:backups schedule --at '02:00 America/Los_Angeles' DATABASE_URL
$ heroku pg:promote DATABASE_URL

$ heroku addons:create heroku-redis:hobby-dev

$ heroku addons:create mailgun:starter

$ heroku config:set PYTHONHASHSEED=random

$ heroku config:set WEB_CONCURRENCY=4

$ heroku config:set DJANGO_DEBUG=False
$ heroku config:set DJANGO_SETTINGS_MODULE=config.settings.production
$ heroku config:set DJANGO_SECRET_KEY="$(openssl rand -base64 64)"

# Generating a 32 character-long random string without any of the visually similar characters "IOl01":
$ heroku config:set DJANGO_ADMIN_URL="$(openssl rand -base64 4096 | tr -dc 'A-HJ-NP-Za-km-z2-9' | head -c 32)/"

# Set this to your Heroku app url, e.g. 'bionic-beaver-28392.herokuapp.com'
$ heroku config:set DJANGO_ALLOWED_HOSTS=

# Assign with AWS_ACCESS_KEY_ID
$ heroku config:set DJANGO_AWS_ACCESS_KEY_ID=

# Assign with AWS_SECRET_ACCESS_KEY
$ heroku config:set DJANGO_AWS_SECRET_ACCESS_KEY=

# Assign with AWS_STORAGE_BUCKET_NAME
$ heroku config:set DJANGO_AWS_STORAGE_BUCKET_NAME=

$ git push heroku master

$ heroku run python manage.py createsuperuser

$ heroku run python manage.py check --deploy

$ heroku open
```

If you encounter a warning, add this to your config/production.py settings then push your repo to Heroku again.

`SECURE_REFERRER_POLICY = 'same-origin'`

After running these commands and following how it was laid out, you would see your app on '<your\_app\_name>.herokuapp.com.'
