LocalStack Lambda with Docker Deployment

This project showcases the deployment of a Python Lambda function using Docker and LocalStack, providing a local simulation of AWS services. It aims to demonstrate the capabilities of LocalStack in a development environment and how Docker can be used to containerize Lambda functions for AWS.

Technologies Used

  • LocalStack: Emulates AWS services locally.
  • AWS Lambda: Serverless computing service.
  • Docker: Containerization platform.
  • Python: Programming language for Lambda function.

Setup Instructions

  1. Install LocalStack to emulate AWS services locally.
  2. Build the Docker image using the provided Dockerfile.
  3. Deploy the Lambda function using LocalStack commands.
  4. Invoke the Lambda function to test its execution locally.

Challenges and Solutions

  • Encountered issues with Lambda invocation output, solved by checking LocalStack logs for correct execution and output handling. Was able to see the correct message: "Hello from LocalStack Lambda container image!".

Learning Outcomes

  • Gained practical experience with AWS Lambda, Docker, and LocalStack.
  • Learned to debug and solve deployment issues in a simulated cloud environment.

Future Improvements

  • Expand the project to include more AWS services.
  • Enhance the Lambda function for more complex scenarios.
