Terraform AWS CloudFront Distribution

This project uses Terraform to set up and manage AWS CloudFront distributions for a static website, checkout process, and other custom distributions on Amazon S3.

Project Structure

• main.tf: Main Terraform configuration file
• variables.tf: Input variables for the Terraform configuration
• outputs.tf: Output values from the Terraform configuration
• providers.tf: Provider configuration for AWS
• modules/: Custom Terraform modules
  • cloudfront_distribution/: Standard CloudFront distribution module
  • custom_cloudfront_distribution/: Customizable CloudFront distribution module

Requirements

• Terraform v0.12+
• AWS CLI configured with appropriate credentials
• An Amazon S3 bucket to host your static website content

Usage

1. Clone this repository
2. Update the variables.tf file with your desired values
3. Run terraform init to initialize the Terraform working directory
4. Run terraform plan to see the execution plan
5. Run terraform apply to create the resources
6. After the resources are created, upload your static website content to the S3 bucket

Variables

Key variables include:

• static_site_bucket_name: Name of the S3 bucket for the static site
• environment: Environment name (e.g., prod, dev, staging)
• cloudfront_price_class: CloudFront distribution price class
• cloudfront_allowed_methods: HTTP methods that CloudFront processes and forwards
• cloudfront_cached_methods: HTTP methods for which CloudFront caches responses
• cloudfront_min_ttl: Minimum time for objects to stay in CloudFront caches
• cloudfront_default_ttl: Default time for objects in CloudFront cache
• cloudfront_max_ttl: Maximum time for objects in CloudFront cache

For a complete list of variables and their descriptions, please refer to the variables.tf file.

Modules

custom_cloudfront_distribution

This module creates a customizable CloudFront distribution. It allows you to specify:

• Origin domain name
• Allowed HTTP methods
• Cached HTTP methods
• Price class
• TTL settings (minimum, default, maximum)
• And more

Outputs

• cdn_distribution_domain: The domain name of the CDN CloudFront distribution
• checkout_distribution_domain: The domain name of the checkout CloudFront distribution

Use these domain names to access your CloudFront-distributed content.

Security

This project uses AWS CloudFront Origin Access Identity (OAI) to secure access to the S3 bucket. Only CloudFront can access the S3 bucket directly.

Customization

You can customize the CloudFront distributions by modifying the custom_cloudfront_distribution module calls in main.tf. Adjust the input variables to change behaviors such as allowed methods, TTL settings, and more.
