How to use ci.yml to declare env variables to be used in python?

Question

-in gitlab-ci.yml

variables:
  SECRET_KEY: secret_key
  DB_NAME: somedb_name
  DB_USER: postgres
  DB_HOST: mdillon-postgis
  DB_PORT: 5432
  DB_PASSWORD: ''

-in django

DATABASES = {
    'default': {
        'ENGINE': 'django.contrib.gis.db.backends.postgis',
        'NAME': os.getenv('DB_NAME'),
        'USER': os.getenv('DB_USER'),
        'PASSWORD': os.getenv('DB_PASSWORD'),
        'HOST': os.getenv('DB_HOST'),
        'PORT': os.getenv('DB_PORT'),
    }
}

Django doesn't seem to pick up the variables declared on CI when running pipeline. How do I properly declare the env variables on testing?

Answer 1

Anyone having the same confusion. Here are the steps:

1. Go to Settings > CI/CD > Variables. Add the variables and values:

  DB_NAME: your_db_name
  DB_USER: postgres
  DB_HOST: mdillon-postgis (or whatever service you are using)
  DB_PORT: 5432
  DB_PASSWORD: <leave it blank>

2. In gitlab-ci.yml

  POSTGRES_DB: $DB_NAME
  POSTGRES_USER: $DB_USER
  POSTGRES_PASSWORD: $DB_PASSWORD
  DATABASE_URL: postgres://postgres:@mdillon__postgis:5432/$DB_NAME

3. In django

DATABASES = {
    'default': {
        'ENGINE': 'django.contrib.gis.db.backends.postgis',
        'NAME': os.getenv('DB_NAME'),
        'USER': os.getenv('DB_USER'),
        'PASSWORD': os.getenv('DB_PASSWORD'),
        'HOST': os.getenv('DB_HOST'),
        'PORT': os.getenv('DB_PORT'),
    }
}
