# FastAPI DevOps Project

This project demonstrates my proficiency in building, securing, containerizing, and deploying a modern web application using FastAPI. The goal is to showcase the end-to-end workflow of a DevOps Engineer, from application development to CI/CD pipeline implementation and cloud deployment.

## Project Overview

The application is a simple FastAPI service that includes JWT-based authentication for securing API endpoints. This project is designed with scalability, security, and automated deployment in mind, using industry-standard DevOps practices.

## Key Features & Technologies

### 1. **FastAPI & JWT Authentication**
- Developed a FastAPI application that serves API endpoints.
- Secured endpoints using **JWT Authentication**, ensuring only authorized users can access protected resources.
- Implemented authentication in Python using FastAPI's built-in support for OAuth2 and JWT tokens.

### 2. **Containerization with Docker**
- Wrote a **multi-stage Dockerfile** to optimize both the build and runtime environments.
- The application runs in an isolated Docker container, ensuring a consistent and portable deployment across different environments.
- Successfully ran the FastAPI app inside Docker and exposed it via `uvicorn`.

### 3. **CI/CD Pipeline with GitHub Actions**
- Implemented an automated CI/CD pipeline using **GitHub Actions** to ensure that every code commit triggers a series of actions:
- Build the Docker container.
- Run tests (to be implemented next).
- Deploy the application seamlessly.

### 4. **Logging and Monitoring**
- **Prometheus** is used to gather application metrics, which are visualized through **Grafana**, ensuring proactive monitoring and observability of the application's performance.
- Added **custom logging** to monitor application behavior, making debugging and troubleshooting easier in production environments (next step in the project).

### 5. **Cloud Deployment on AWS**
- Planned deployment on an **AWS EC2 instance**, where the application will run in a scalable cloud environment. This step will demonstrate the ability to manage infrastructure as code and deploy to cloud environments (coming soon).

### 6. **Security Best Practices**
- JWT authentication ensures only verified users can access sensitive data.
- Docker and AWS security groups are configured to minimize attack vectors and provide secure, scalable architecture.

## DevOps Skills Highlighted
This project demonstrates my expertise in:
- **Application Development**: Building secure, scalable APIs using FastAPI and Python.
- **Containerization**: Creating and optimizing Docker containers for consistent application deployment.
- **Automation & CI/CD**: Leveraging GitHub Actions for continuous integration and deployment.
- **Infrastructure Management**: Deploying applications to AWS and ensuring secure, scalable cloud architecture.
- **Monitoring & Logging**: Implementing Prometheus and Grafana for real-time application performance monitoring.
- **Security**: Utilizing JWT authentication and Docker security practices to protect and maintain secure environments.

## Project Milestones
- ✅ Completed JWT Authentication and protected endpoints.
- ✅ Successfully containerized the FastAPI app with Docker.
- ✅ Integrated CI/CD pipeline with GitHub Actions for automated testing and deployment.
- ⏳ Adding automated tests to improve application reliability.
- ⏳ Implementing logging, monitoring, and Prometheus/Grafana setup.
- ⏳ AWS EC2 deployment with scalability and security measures.

## Conclusion
This project demonstrates my technical capabilities in DevOps, showcasing an end-to-end approach from application development to automated cloud deployment. Through this project, I have implemented best practices in containerization, CI/CD pipelines, cloud infrastructure, and application security.
