📦 FastAPI Deploy Pipeline

Description: This project is a production-ready, containerized FastAPI application. It is fully automated for continuous integration and deployment using GitHub Actions, Docker, and Terraform on AWS EC2. The pipeline integrates automated unit and API testing, failure recovery via rollback scripts, and structured manual QA validation processes.

🔄 Deployment Workflow

1. Code is committed and pushed to the GitHub repository.
2. CI/CD pipeline is triggered via GitHub Actions:
   • Execute unit and integration tests
   • Build Docker image
   • Push image to DockerHub
   • Provision AWS EC2 resources via Terraform
   • Deploy Docker container to provisioned infrastructure
3. On deployment failure:
   • rollback.sh is invoked to restore the previous stable version
4. Post-deployment QA:
   • Execution of postman_collection.json
   • Validation against manual_test_cases.md

🔁 Rollback Mechanism

Deployment failures are handled through an automated rollback process using rollback.sh, restoring the last known stable container state to ensure high availability and system integrity.
