🔹 Prerequisites

Before deploying to Elastic Beanstalk, ensure you have these requirements set up. You'll need an AWS account and the EB CLI tool installed on your computer.

What You Need:

AWS Account: Sign up at aws.amazon.com
EB CLI: Install with pip
Django Project: Working Django application
Git: Version control (optional but recommended)

# Install EB CLI
pip install awsebcli

# Verify installation
eb --version

🔹 Configure Django Settings

Update your Django settings to work with Elastic Beanstalk. These configurations ensure your app runs properly in the AWS environment with correct security and database settings.

# settings.py
import os

# SECURITY WARNING: keep the secret key used in production secret!
SECRET_KEY = os.environ.get('SECRET_KEY', 'your-default-secret-key')

# SECURITY WARNING: don't run with debug turned on in production!
DEBUG = os.environ.get('DEBUG', 'False') == 'True'

ALLOWED_HOSTS = [
    'localhost',
    '127.0.0.1',
    '.elasticbeanstalk.com',  # Allow EB domains
    os.environ.get('ALLOWED_HOST', '')
]

# Database configuration
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': os.environ.get('RDS_DB_NAME', 'mydatabase'),
        'USER': os.environ.get('RDS_USERNAME', 'myuser'),
        'PASSWORD': os.environ.get('RDS_PASSWORD', 'mypassword'),
        'HOST': os.environ.get('RDS_HOSTNAME', 'localhost'),
        'PORT': os.environ.get('RDS_PORT', '5432'),
    }
}

# Static files
STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')
STATIC_URL = '/static/'

🔹 Initialize Elastic Beanstalk

Set up your project for Elastic Beanstalk deployment. This creates configuration files and connects your project to AWS.

# Navigate to your project directory
cd my-django-project

# Initialize EB (interactive setup)
eb init

# Or specify options directly
eb init -p python-3.9 my-django-app --region us-east-1

# This creates .elasticbeanstalk/config.yml

During eb init, you'll be asked:

Select a region (e.g., us-east-1)
Application name
Python version
SSH access (optional)

🔹 Create Environment

Create and launch your application environment on AWS. This sets up servers, load balancers, and all infrastructure needed to run your Django app.

# Create environment and deploy
eb create my-environment

# Or with specific options
eb create production-env --database.engine postgres --database.username myuser

# Check status
eb status

# Open in browser
eb open

Output:

Creating application version archive "app-231015_123456".
Uploading my-django-app/app-231015_123456.zip to S3...
Environment details for: production-env
  Application name: my-django-app
  Region: us-east-1
  Platform: Python 3.9
  Status: Ready
  Health: Green

🔹 Deploy Updates

Deploy code changes to your running environment with a single command:

# Deploy current code
eb deploy

# Deploy with message
eb deploy -m "Added new feature"

# View logs
eb logs

# SSH into instance
eb ssh

🔹 Environment Variables

Set environment variables for your Django app securely through EB:

# Set environment variables
eb setenv SECRET_KEY=your-secret-key DEBUG=False

# Set multiple variables
eb setenv \
  SECRET_KEY=your-secret-key \
  DEBUG=False \
  ALLOWED_HOST=myapp.com

# View current variables
eb printenv

🔹 Common EB Commands

Essential commands for managing your Elastic Beanstalk application:

Useful Commands:

eb status: Check environment status
eb health: View health information
eb logs: View application logs
eb open: Open app in browser
eb terminate: Delete environment
