FastAPI DevOps Pipeline Architecture 🚀

A comprehensive visual guide to implementing a modern DevOps pipeline using FastAPI, GitHub Actions, ArgoCD, and Amazon EKS with complete monitoring and logging setup.

📋 Overview

This project provides an interactive HTML visualization of a production-ready DevOps architecture that demonstrates:

• CI/CD Pipeline with GitHub Actions
• GitOps Deployment using ArgoCD
• Container Orchestration on Amazon EKS
• Comprehensive Monitoring with CloudWatch, Fluent Bit, and Grafana

🎯 Architecture Components

1. CI/CD Pipeline (GitHub Actions)

• Automated testing with pytest
• Code formatting with black
• Docker image building and pushing to ECR
• GitOps repository updates

2. GitOps with ArgoCD

• Declarative deployments
• Git as single source of truth
• Automated synchronization with EKS cluster
• Rollback capabilities

3. Infrastructure (EKS/EC2)

• Managed Kubernetes cluster
• Auto-scaling EC2 worker nodes
• AWS Load Balancer integration
• Security group configurations

4. Monitoring & Logging

• Fluent Bit for log collection
• CloudWatch integration
• Grafana dashboards
• Prometheus metrics

🚀 Quick Start

1. Clone the repository

   git clone modern-fastapi-pipeline
   cd modern-fastapi-pipeline

2. Open the visualization

   # Option 1: Open directly in browser
   open index.html
   
   # Option 2: Serve locally (recommended)
   python -m http.server 8000
   # Then visit: http://localhost:8000

3. View the interactive diagram

   • Navigate through different pipeline stages
   • Hover over components for detailed information
   • Explore the end-to-end flow visualization

🔧 Implementation Guide

Prerequisites

• AWS Account with EKS permissions
• GitHub repository
• Basic knowledge of Kubernetes and Docker

Step-by-Step Implementation

1. Set up GitHub Actions

   • Configure AWS credentials using OIDC
   • Create ECR repository
   • Set up pytest and black in CI pipeline

2. Configure GitOps Repository

   • Create separate repository for Kubernetes manifests
   • Structure environments (dev, staging, prod)
   • Set up Helm charts or Kustomize

3. Deploy ArgoCD on EKS

   • Install ArgoCD in cluster
   • Configure repository connections
   • Set up RBAC and permissions

4. Set up Monitoring Stack

   • Deploy Fluent Bit DaemonSet
   • Configure CloudWatch integration
   • Install Prometheus and Grafana
