API Gateway Proxy with Lambda Authorizer

This project sets up an API Gateway that acts as a proxy, using a Lambda authorizer to authenticate requests for internal resources. The API Gateway routes incoming requests to the appropriate backend services, ensuring that only authenticated requests are processed.

Dependencies

• VPC
• NLB (Network Load Balancer)

Features

• API Gateway Proxy: Acts as a proxy to route requests to backend services.
• Lambda Authorizer: Authenticates incoming requests to ensure they are valid.
• Internal Resource Protection: Ensures that only authenticated requests can access internal resources.

Prerequisites

• AWS Account
• AWS CLI configured with appropriate permissions
• Node.js and npm installed

• aws_api_gateway_rest_api: Defines the API Gateway.
• aws_api_gateway_resource: Creates resources within the API Gateway.
• aws_api_gateway_method: Defines methods for the API Gateway resources.
• aws_lambda_function: Deploys the Lambda authorizer function.
• aws_iam_role: Creates IAM roles for the Lambda function and API Gateway.
• aws_iam_policy: Attaches policies to the IAM roles.
• aws_api_gateway_authorizer: Configures the Lambda authorizer for the API Gateway.

Terraform Output

After running terraform apply, the following outputs will be provided:

• api_gateway_url: The URL of the deployed API Gateway.
• lambda_authorizer_arn: The ARN of the deployed Lambda authorizer function.
