Deployment

1. Create a Heroku application through heroku.com

2. Setup postgres database in Heroku

   Create 2 postgres database add-ons through the heroku app’s resources page.

   One will be used for production and the other for testing.

3. Set CI/CD script by creating .gitlab-ci.yml file

   Create stages needed

   For this case, the stages are test for testing, sonar-scanner for sonar scanner, and deploy for deployment

   View this file for reference

4. Set variables needed in .gitlab-ci.yml file at Settings > CI/CD > Variables

   HEROKU_APIKEY = your api key from your account settings

   HEROKU_APP_HOST = the heroku app host or url

   HEROKU_APPNAME = the heroku app name

   SONARQUBE_PROJECT_KEY = the project key of your sonarqube

   SONARQUBE_TOKEN = the token of your sonarqube

   DATABASE_URL = your database url from your heroku production database credential

   TEST_DATABASE_URL = your database url from your heroku testing database credential

   TEST_DATABASE = the database name from your heroku testing database credential

5. Configure settings.py:

import dj_database_url
 
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
        'TEST': {
            'NAME': os.environ.get('TEST_DATABASE'),
        },
    }
}
 
# Heroku: Update database configuration from $DATABASE_URL.
db_from_env = dj_database_url.config(conn_max_age=600)
DATABASES['default'].update(db_from_env)

6. Create deployment.sh file

#!/bin/bash
python manage.py makemigrations
python manage.py migrate

7. Create Procfile file

migrate: bash deployment.sh
web: gunicorn dietela_backend.wsgi --log-file -

8. Commit and push to your repository
