1. Initialize the Project Repository: o Create a GitHub repository for your project.
2. Build the Three Microservices: o Develop the User service, Product service, and Cart service. o Containerize the microservices for easy deployment later on. o A minimal low-level logic is sufficient. Using an open-source codebase is acceptable. o You can use the above reference link for this part or if you want to write your own services you are free to do so.
3. Write Dockerfiles: o Create separate Dockerfiles for each microservice. o Optimize each Dockerfile for a production environment.
4. Create Docker Compose Configuration: o Define and manage the services for your E-commerce system using dockercompose.yml. o Ensure services are correctly configured to communicate with each other.
5. Run the Multi-Container Application: o Use Docker Compose to start all services with a single command (dockercompose up). o Verify that all services are running correctly and the application is accessible.

Level 2: CI/CD Setup and Automated Deployment

1. Set Up GitHub Actions: o Create a GitHub Actions workflow file for CI/CD. o Configure the workflow to trigger on pushes to the main branch.
2. Configure Docker Build and Push: o Add steps to the workflow to build the Docker images for each microservice. o Push the Docker images to Docker Hub.
3. Set Up Deployment Script: o Write a deployment script (e.g., deploy.sh) that pulls the latest Docker images and restarts the microservices using Docker Compose. o Ensure the script handles errors gracefully and logs deployment details.
