Introduction to Heroku Deployment

Heroku is a popular cloud platform for building and deploying web applications. In this tutorial, we will explore how to deploy a Django app to Heroku.

Step 1: Create a Heroku Account

Create a Heroku account and install the Heroku CLI:

brew install heroku

Step 2: Initialize a Git Repository

Initialize a Git repository for your Django project:

git init

Step 3: Create a Heroku App

Create a new Heroku app using the Heroku CLI:

heroku create

Step 4: Configure the Django App for Heroku

Configure the Django app to use Heroku's PostgreSQL database:

import os

database = {
    'ENGINE': 'django.db.backends.postgresql_psycopg2',
    'NAME': os.environ.get('DATABASE_NAME'),
    'USER': os.environ.get('DATABASE_USER'),
    'PASSWORD': os.environ.get('DATABASE_PASSWORD'),
    'HOST': os.environ.get('DATABASE_HOST'),
    'PORT': os.environ.get('DATABASE_PORT'),
}

Step 5: Deploy the App to Heroku

Deploy the app to Heroku using the Heroku CLI:

git add .
git commit -m 'Initial commit'
heroku git:remote -a <app-name>
git push heroku master

Step 6: Run Migrations and Collect Static Files

Run migrations and collect static files on the Heroku server:

heroku run python manage.py migrate
heroku run python manage.py collectstatic
