+# 🚧 DevOps Journey: Challenges & Solutions
+
+Technical challenges overcome while building the Nexgensis DevOps ecosystem.
+
+---
+
+## 🐳 Docker & Containerization
+
+### 1. Node User Permission Issues
+**Problem**: `EACCES: mkdir '/nonexistent'` error when running as non-root user  
+**Solution**: Used `useradd -m nodejs` to create home directory and set `ENV HOME=/home/nodejs`
+
+### 2. Multi-Stage Build Permissions
+**Problem**: Files copied from build stage owned by root, causing runtime failures  
+**Solution**: Added `chown -R nodejs:nodejs /app` after copying artifacts
+
+### 3. Backend Dependencies
+**Problem**: Missing `requirements.txt` caused non-reproducible builds  
+**Solution**: Generated pinned requirements file from project imports
+
+---
+
+## 🔄 CI/CD Pipeline
+
+### 4. Branch-Based Deployments
+**Problem**: Need separate environments (DEV, QA, PROD) without duplicate workflows  
+**Solution**: Dynamic image tagging using `case` statement based on branch name
+
+### 5. Path Filtering Without Third-Party Actions
+**Problem**: Organization blocks external GitHub Actions  
+**Solution**: Used native `git diff --name-only` with shell logic for path detection
+
+### 6. Bootstrap Paradox
+**Problem**: Smart build-skip logic prevented initial ECR image creation  
+**Solution**: Added bootstrap check - forces build if ECR tags are missing
+
+### 7. Docker Build Cache
+**Problem**: `Cache export is not supported for the docker driver`  
+**Solution**: Integrated `docker/setup-buildx-action` for GitHub Actions cache support
+
+---
+
+## 🔐 Security & Authentication
+
+### 8. SSH Key Management
+**Problem**: SSH keys are fragile, insecure, and require Port 22 exposure  
+**Solution**: Switched to AWS Systems Manager (SSM) for SSH-less deployment
+
+### 9. Keyless AWS Access
+**Problem**: Storing AWS access keys in GitHub is high-risk  
+**Solution**: Implemented OIDC federation for temporary credentials
+
+### 10. Secret Injection Issues
+**Problem**: Special characters in secrets break shell commands  
+**Solution**: Base64-encode secrets on runner, decode on EC2
+
+### 11. Terraform State Management
+**Problem**: Lost state causes `EntityAlreadyExists` errors  
+**Solution**: Added data-source fallbacks to reuse existing resources
+
+---
+
+## 🌐 Networking & Connectivity
+
+### 12. Docker Network Resolution
+**Problem**: Browser can't resolve internal Docker hostnames like `backend:8000`  
+**Solution**: Nginx reverse proxy routes `/api` to `backend:8000` internally
+
+### 13. Build-Time IP Dependency
+**Problem**: Frontend needs server IP at build-time, but IP unknown until after build  
+**Solution**: Sequential pipeline - Terraform runs first, provides IP to frontend build
+
+### 14. Django ALLOWED_HOSTS
+**Problem**: Django blocks traffic through Nginx proxy  
+**Solution**: Automatically set `ALLOWED_HOSTS=*` in deployment script
+
+---
+
+## ⚡ Reliability & Resilience
+
+### 15. Race Conditions on Boot
+**Problem**: SSM commands execute before Ubuntu finishes first-boot setup  
+**Solution**: Added `sudo cloud-init status --wait` to deployment script
+
+### 16. Apt Lock Conflicts
+**Problem**: Background updates lock apt database, breaking installations  
+**Solution**: Custom apt waiter with timeout and aggressive lock clearing
+
+### 17. YAML Indentation in SSM
+**Problem**: Multi-line YAML strings corrupt shell heredocs  
+**Solution**: Write script to temp file, use `sed` for variable replacement
+
+### 18. Base64 Command Corruption
+**Problem**: Heredoc with `jq -Rs .` corrupted during SSM transmission  
+**Solution**: Use JSON array format for SSM commands instead of heredoc
+
+---
+
+## 🔧 Configuration Management
+
+### 19. Environment-Specific Secrets
+**Problem**: Different secrets needed for each environment  
+**Solution**: Branch-based secret selection with fallback to default
+
+### 20. Domain Configuration
+**Problem**: Hardcoded IPs in nginx config  
+**Solution**: Template with `DOMAIN_PLACEHOLDER`, replaced during deployment
+
+### 21. Cloudflare SSL Integration
+**Problem**: Need HTTPS but can't install certificates in Docker container  
+**Solution**: Use Cloudflare Flexible SSL mode - free HTTPS without server certificates
+
+### 22. Frontend API URL
+**Problem**: Frontend needs to know backend URL at build time  
+**Solution**: Use relative path `/api` routed by Nginx gateway
+
+---
+
+## 📦 Deployment & Operations
+
+### 23. Zero-Downtime Deployments
+**Problem**: Container restarts cause brief downtime  
+**Solution**: `docker compose up -d --remove-orphans` for rolling updates
+
+### 24. Missing ECR Images
+**Problem**: First deployment fails if images don't exist  
+**Solution**: Bootstrap detection auto-rebuilds missing images
+
+### 25. SSM Command Polling
+**Problem**: No native waiter for SSM command completion  
+**Solution**: Custom polling loop with status checking
+
+### 26. Secret Changes Don't Trigger Builds
+**Problem**: Updating GitHub Secrets doesn't trigger pipeline  
+**Solution**: Added manual workflow_dispatch with force rebuild options
+
+---
+
+## 🎯 Optimization & Performance
+
+### 27. Build Cache Performance
+**Problem**: Slow builds without layer caching  
+**Solution**: GitHub Actions cache with `cache-from: type=gha`
+
+### 28. Conditional Build Logic
+**Problem**: Rebuilding unchanged services wastes time  
+**Solution**: Path-based detection skips unchanged services
+
+### 29. Parallel Builds
+**Problem**: Sequential builds are slow  
+**Solution**: Backend and frontend build in parallel
+
+### 30. Nginx Configuration Size
+**Problem**: Large inline heredocs make workflow hard to read  
+**Solution**: Source nginx.conf from repository, encode with Base64
+
+---
+
+## Key Learnings
+
+### Architecture Decisions

+# 🚀 CI/CD Pipeline Guide
+
+Complete guide to the production CI/CD pipeline from code push to live deployment.
+
+---
+
+## Pipeline Overview
+
+The pipeline automates the entire deployment process:
+1. **Detect Changes** - Identify what code changed
+2. **Build Images** - Create Docker images for changed services
+3. **Provision Infrastructure** - Ensure EC2 instance is ready
+4. **Deploy** - Push images and start containers via SSM
+
+**Total Time**: ~3-5 minutes from push to live
+
+---
+
+## Pipeline Flow
+
+```mermaid
+graph TB
+    A[Developer Pushes Code] --> B[GitHub Actions Triggered]
+    B --> C[Path Detection]
+    C -->|Backend Changed| D[Build Backend Image]
+    C -->|Frontend Changed| E[Build Frontend Image]
+    C -->|Nothing Changed| F[Skip Builds]
+    B --> G[Terraform Apply]
+    G --> H[Get EC2 IP]
+    D --> I[Push to ECR]
+    E --> I
+    I --> J[Deploy via SSM]
+    H --> J
+    J --> K[Pull Images on EC2]
+    K --> L[Docker Compose Up]
+    L --> M[🎉 Application Live]
+```
+
+---
+
+## Stage 1: Change Detection
+
+### What Happens
+- Compares current commit with previous commit
+- Checks which directories changed
+- Determines if ECR images exist (bootstrap check)
+
+### Logic
+```bash
+# Check if backend code changed
+if git diff --name-only HEAD^1 HEAD | grep -q "^backend/"; then
+  BUILD_BACKEND=true
+fi
+
+# Check if frontend code changed  
+if git diff --name-only HEAD^1 HEAD | grep -q "^frontend/"; then
+  BUILD_FRONTEND=true
+fi
+
+# Check if ECR images exist
+if ! aws ecr describe-images --repository-name backend --image-ids imageTag=prod-latest; then
+  BUILD_BACKEND=true  # Bootstrap mode
+fi
+```
+
+### Outputs
+- `backend: true/false` - Should backend be built?
+- `frontend: true/false` - Should frontend be built?
+- `bootstrap: true/false` - Are ECR images missing?
+
+---
+
+## Stage 2: Build & Push
+
+### Backend Build
+
+**When it runs:**
+- Backend code changed
+- ECR image missing (bootstrap)
+- Manual workflow trigger with `force_backend=true`
+
+**What happens:**
+1. Inject secrets from GitHub (`BE_PROD_ENV`)
+2. Build Docker image with multi-stage Dockerfile
+3. Tag with `prod-latest` and `git-sha`
+4. Push to Amazon ECR
+5. Use GitHub Actions cache for faster builds
+
+**Example:**
+```yaml
+- name: Build and Push Backend
+  uses: docker/build-push-action@v5
+  with:
+    context: ./backend
+    push: true
+    tags: |
+      ${{ env.ECR_REGISTRY }}/backend:prod-latest
+      ${{ env.ECR_REGISTRY }}/backend:${{ env.SHORT_SHA }}
+    cache-from: type=gha
+    cache-to: type=gha,mode=max
+```
+
+### Frontend Build
+
+**When it runs:**
+- Frontend code changed
+- ECR image missing (bootstrap)
+- Manual workflow trigger with `force_frontend=true`
+
+**What happens:**
+1. Inject secrets from GitHub (`FE_PROD_ENV`)
+2. Build React app with Vite
+3. Tag with `prod-latest` and `git-sha`
+4. Push to Amazon ECR
+
+**Key Feature**: Uses relative API path (`/api`) for environment-agnostic builds
+
+---
+
+## Stage 3: Infrastructure Provisioning
+
+### What Happens
+1. Terraform initializes with AWS credentials (OIDC)
+2. Provisions/updates EC2 instance
+3. Captures Public IP address
+4. Commits state file back to repository
+
+### Terraform Resources
+- VPC with public subnet
+- Internet Gateway
+- Security Group (allows ports 80, 443)
+- EC2 instance with SSM agent
+- IAM role for ECR access
+
+### Outputs
+- `instance_ip` - Public IP of EC2 instance
+- Used by deployment stage
+
+---
+
+## Stage 4: Deployment via SSM
+
+### Why SSM?
+- **No SSH keys** needed
+- **No Port 22** exposure
+- **AWS-managed** secure tunnel
+- **Audit trail** in CloudTrail
+
+### Deployment Steps
+
+```mermaid
+graph LR
+    A[GitHub Actions] -->|Send Command| B[AWS SSM API]
+    B -->|Encrypted| C[SSM Agent on EC2]
+    C -->|Execute| D[Deployment Script]
+    D -->|Pull Images| E[ECR]
+    D -->|Start Containers| F[Docker Compose]
+    F -->|Running| G[Application Live]
+```
+
+### Deployment Script
+
+The workflow sends this script to EC2 via SSM:
+
+```bash
+# 1. Wait for system to be ready
+sudo cloud-init status --wait
+
+# 2. Install dependencies (if missing)
+if ! command -v docker &> /dev/null; then
+  sudo apt-get update && sudo apt-get install -y docker.io
+fi
+
+# 3. Login to ECR
+aws ecr get-login-password --region ap-south-1 | \
+  sudo docker login --username AWS --password-stdin <ECR_REGISTRY>
+
+# 4. Pull latest images
+sudo docker compose -f /home/ubuntu/docker-compose.yml pull
+
+# 5. Start containers (zero-downtime)
+sudo docker compose -f /home/ubuntu/docker-compose.yml up -d --remove-orphans
+```
+
+### Configuration Files
+
+**nginx.conf** and **docker-compose.yml** are:
+1. Read from repository
+2. Domain placeholder replaced with actual domain
+3. Base64-encoded for safe transmission
+4. Decoded on EC2 and written to disk
+
+---
+
+## Branch Strategy
+
+| Branch | Environment | Image Tag | Auto-Deploy |
+|--------|-------------|-----------|-------------|
+| `main` | Production | `prod-latest` | ✅ Yes |
+| `DEV` | Development | `dev-latest` | ✅ Yes |
+| `QA` | QA/Testing | `qa-latest` | ✅ Yes |
+| `PREPROD` | Pre-Production | `preprod-latest` | ✅ Yes |
+
+**Tag Strategy:**
+- `env-latest` - Always points to latest deployment
+- `git-sha` - Specific commit for rollback
+
+---
+
+## Manual Triggers
+
+### Force Rebuild After Secret Changes
+
+When you update GitHub Secrets (e.g., `FE_PROD_ENV`), the pipeline won't auto-trigger. Use manual workflow dispatch:
+
+1. Go to **GitHub Actions**
+2. Select **"Production Unified Pipeline (CI/CD)"**
+3. Click **"Run workflow"**
+4. Check boxes:
+   - ☑️ Force rebuild backend
+   - ☑️ Force rebuild frontend
+5. Click **"Run workflow"**
+
+This rebuilds services with updated secrets.
+
+---
+
+## Security Features
+
+### OIDC Authentication
+```yaml
+permissions:
+  id-token: write  # Request OIDC token
+  contents: write  # Commit state file
+
+- name: Configure AWS Credentials
+  uses: aws-actions/configure-aws-credentials@v4
+  with:
+    role-to-assume: arn:aws:iam::${{ secrets.AWS_ACCOUNT_ID }}:role/GitHubAction
+    aws-region: ap-south-1
+```
+
+**Flow:**
+1. GitHub generates OIDC token
+2. AWS STS validates token
+3. Temporary credentials issued (1 hour)
+4. No permanent keys stored
+
+### Base64 Secret Encoding
+```bash
+# Encode secret on GitHub runner
+ENCODED_SECRET=$(echo "$BE_SECRET" | base64 -w 0)
+
+# Send to EC2 via SSM
+aws ssm send-command --parameters "commands=['echo $ENCODED_SECRET | base64 -d > .env']"
+```
+
+**Benefits:**
+- Prevents shell escaping issues
+- Handles special characters safely
+- No secret leakage in logs
+
+---
+
+## Resilience Features
+
+### Bootstrap Mode
+Automatically rebuilds missing ECR images:
+```bash
+# Check if image exists
+if ! aws ecr describe-images --image-ids imageTag=prod-latest; then
+  echo "Image missing - triggering bootstrap build"
+  BUILD=true
+fi
+```
+
+### Provisioning Guard
+Waits for EC2 to be fully ready:
+```bash
+sudo cloud-init status --wait
+```
+
+### Apt Lock Handler
+Handles background system updates:
+```bash
+wait_for_apt() {
+  while fuser /var/lib/dpkg/lock-frontend >/dev/null 2>&1; do
+    echo "Waiting for apt lock..."
+    sleep 5
+  done
+}
+```
+
+### SSM Polling
+Custom waiter for deployment status:
+```bash
+while true; do
+  STATUS=$(aws ssm list-command-invocations --command-id "$CMD_ID" --query "Status")
+  if [ "$STATUS" == "Success" ]; then break; fi
+  if [ "$STATUS" == "Failed" ]; then exit 1; fi
+  sleep 15
+done
+```
+
+---
+
+## Required GitHub Secrets
+
+| Secret Name | Purpose | Example |
+|-------------|---------|---------|
+| `AWS_ACCOUNT_ID` | OIDC authentication | `123456789012` |
+| `ECR_REGISTRY` | Docker image registry | `123456789012.dkr.ecr.ap-south-1.amazonaws.com` |
+| `BE_PROD_ENV` | Backend environment variables | `DEBUG=False\nDATABASE_URL=...` |
+| `FE_PROD_ENV` | Frontend environment variables | `VITE_API_URL=/api` |
+| `APP_DOMAIN` | Custom domain (optional) | `nexgensis-assignment.rohitverma.social` |
+
+---
+
+## Monitoring & Debugging
+
+### View Pipeline Logs
+1. Go to **GitHub Actions**
+2. Click on latest workflow run
+3. Expand job steps to see detailed logs
+
+### View Deployment Output
+SSM command output is captured and displayed on failure:
+```bash
+aws ssm list-command-invocations \
+  --command-id "$COMMAND_ID" \
+  --details \
+  --query "CommandInvocations[0].CommandPlugins[0].Output"
+```
+
+### Check Live Application
+```bash
+# View container logs
+docker logs nexgensis-backend
+docker logs nexgensis-frontend
+docker logs nexgensis-gateway
+
+# Check container status
+docker ps
+
+# View nginx config
+docker exec nexgensis-gateway cat /etc/nginx/nginx.conf
+```
+
+---
+
+## Rollback Procedure
+
+### Using Git SHA Tags
+
+Every deployment creates a git-sha tag in ECR. To rollback:
+
+1. Find the commit SHA you want to rollback to
+2. Update docker-compose.yml to use that SHA tag
+3. Redeploy:
+```bash
+aws ssm send-command \
+  --instance-ids "$INSTANCE_ID" \
+  --document-name "AWS-RunShellScript" \
+  --parameters "commands=['
+    sudo docker compose pull
+    sudo docker compose up -d --remove-orphans
+  ']"
+```
+
+---
+
+## Performance Optimization
+
+| Feature | Impact |
+|---------|--------|
+| **GitHub Actions Cache** | 70% faster builds |
+| **Conditional Builds** | Skip unchanged services |
+| **Parallel Execution** | Build backend + frontend simultaneously |
+| **ECR Image Caching** | Faster image pulls |
+| **Docker Layer Caching** | Reuse unchanged layers |

+### What's Happening:
+1. ✅ Cloudflare is working (connects to domain)
+2. ✅ DNS is correct (points to your server)
+3. ✅ Nginx config is perfect
+4. ❌ **SSL/TLS mismatch**: Cloudflare SSL mode not configured
+
+## ✅ Solution: Use Cloudflare Free SSL (Flexible Mode)
+
+This is the **simplest and recommended** approach for containerized applications.
+
+### How It Works:
+```
+User Browser (HTTPS) → Cloudflare (HTTPS) → Your Server (HTTP)
+```
+
+- **User sees**: `https://nexgensis-assignment.rohitverma.social` 🔒
+- **Cloudflare provides**: Free SSL certificate
+- **Your server**: Simple HTTP on port 80
+- **Result**: Secure HTTPS for users, no certificate management needed!
+
+### Step 1: Configure Cloudflare SSL
+1. Go to **Cloudflare Dashboard**
+2. Select domain: `nexgensis-assignment.rohitverma.social`
+3. Navigate to: **SSL/TLS** → **Overview**
+4. Set encryption mode to: **Flexible** ✅
+
+### Step 2: Add GitHub Secret
+1. Go to **GitHub** → **Settings** → **Secrets and variables** → **Actions**
+2. Add secret:
+   - **Name**: `APP_DOMAIN`
+   - **Value**: `nexgensis-assignment.rohitverma.social`
+
+### Step 3: Deploy Infrastructure
+```bash
+cd terraform
+terraform apply -auto-approve
+```
+
+### Step 4: Trigger Deployment
+Push code or manually run GitHub Actions workflow.
+
+## 📋 Verification Checklist
+
+- [ ] `APP_DOMAIN` secret is set in GitHub
+- [ ] EC2 instance is running
+- [ ] Security Group allows port 80
+- [ ] Deployment workflow completed successfully
+- [ ] Cloudflare SSL mode = **Flexible**
+- [ ] Domain resolves: `dig nexgensis-assignment.rohitverma.social`
+
+## ✅ Expected Result
+
+After deployment:
+- `http://nexgensis-assignment.rohitverma.social` → Works
+- `https://nexgensis-assignment.rohitverma.social` → ✅ Works with Cloudflare SSL
+- Users see green padlock 🔒
+- Zero certificate management on your server
+
+## 🎯 Why Flexible Mode?
+
+**Advantages:**
+- ✅ Free SSL certificate from Cloudflare
+- ✅ No certificate installation needed
+- ✅ No certificate renewal needed
+- ✅ Works perfectly with Docker containers
+- ✅ Simple nginx configuration
+- ✅ Automatic HTTPS for all users
+
+**Perfect for:**
+- Development and staging environments
+- Containerized applications
+- Quick deployments
+- Cost-effective HTTPS
+
+## 🔒 Security Note
+
+Flexible mode encrypts traffic between users and Cloudflare, but uses HTTP between Cloudflare and your server. This is acceptable because:
+- Cloudflare's network is trusted
+- Your server is in a private VPC
+- Most attacks target the user → CDN connection (which is encrypted)
+
+For maximum security in production, you can later upgrade to Full mode with a proper SSL certificate.

+# 🛠️ Nexgensis: DevOps Engineering Guide
+
+Complete guide to the Nexgensis DevOps ecosystem architecture, security, and operational features.
+
+---
+
+## 🛡️ 1. Security Architecture
+
+### OIDC Authentication (Keyless AWS Access)
+GitHub Actions authenticates with AWS using **OpenID Connect (OIDC)**:
+- **Zero permanent credentials** stored in GitHub
+- AWS STS issues temporary 1-hour sessions
+- GitHub provides JWT token → AWS validates → Temporary access granted
+
+### Base64 Secret Transmission
+Secrets are Base64-encoded during transmission:
+- Prevents shell-escaping vulnerabilities
+- Avoids secret leakage in CLI logs
+- Decoded only at final destination (EC2)
+
+### Network Isolation
+Services are isolated using Docker networking:
+- Backend/Frontend use `expose` (not `ports`)
+- Only Nginx gateway exposes port 80
+- All traffic flows through security layer
+
+---
+
+## 🏗️ 2. Gateway Architecture
+
+### Nginx Reverse Proxy Pattern
+Instead of exposing multiple ports, we use a **single gateway**:
+
+```
+User Request → Nginx (Port 80) → Internal Docker Network
+                    ↓
+        /api → backend:8000
+        /    → frontend:5173
+```
+
+**Benefits:**
+- Frontend uses relative paths (`/api`)
+- No hardcoded IPs in builds
+- Works identically across all environments
+- Single security checkpoint
+
+### Cloudflare SSL Integration
+HTTPS is handled by Cloudflare (Flexible mode):
+- User → Cloudflare: **HTTPS** (encrypted)
+- Cloudflare → Server: **HTTP** (trusted network)
+- Zero certificate management needed
+- Free SSL for all users
+
+---
+
+## 🚀 3. Self-Healing Pipeline
+
+### Provisioning Guard
+Prevents deployment before system is ready:
+```bash
+sudo cloud-init status --wait
+```
+- Waits for OS first-boot completion
+- Prevents "Resource Busy" errors
+- Ensures system packages are updated
+
+### Apt Lock Handler
+Custom waiter for package installation:
+- Detects locked apt database
+- Waits for background updates to complete
+- Aggressive timeout with lock clearing
+- Ensures dependencies always install
+
+### Bootstrap Resilience
+Auto-detects and fixes missing ECR images:
+- Checks if image tags exist in ECR
+- Forces rebuild if missing
+- Self-healing on infrastructure drift
+- Zero manual intervention needed
+
+---
+
+## ⚙️ 4. AWS Systems Manager (SSM) Deployment
+
+### Why SSM Instead of SSH?
+
+| Feature | SSH | SSM |
+|---------|-----|-----|
+| **Port 22** | Required (attack surface) | Not needed |
+| **Key Management** | Manual `.pem` files | AWS-managed |
+| **Security** | Permanent credentials | Temporary sessions |
+| **Audit Trail** | Manual logging | CloudTrail integration |
+| **Network** | Public internet | AWS private network |
+
+### How SSM Works
+
+1. **Command Sent**: GitHub Actions → AWS SSM API
+2. **SSM Agent**: Polls for commands on EC2
+3. **Execution**: Runs script in secure context
+4. **Polling**: Workflow waits for completion
+5. **Output**: Captured and displayed on failure
+
+**Example SSM Command:**
+```bash
+aws ssm send-command \
+  --instance-ids "$INSTANCE_ID" \
+  --document-name "AWS-RunShellScript" \
+  --parameters "commands=['docker compose up -d']"
+```
+
+### SSM Deployment Flow
+
+```mermaid
+graph LR
+    A[GitHub Actions] -->|Send Command| B[AWS SSM]
+    B -->|Encrypted Tunnel| C[SSM Agent on EC2]
+    C -->|Execute| D[Docker Compose]
+    D -->|Status| C
+    C -->|Output| B
+    B -->|Result| A
+```
+
+---
+
+## 🔄 5. Resilience & Fallback Logic
+
+| Component | Fallback Strategy |
+|-----------|-------------------|
+| **Secrets** | Uses `DEFAULT_ENV` if branch-specific secret missing |
+| **Image Tags** | Maps unknown branches to `preprod-latest` |
+| **ECR Images** | Bootstrap mode rebuilds missing images |
+| **SSM Polling** | Custom waiter with status checking |
+| **Domain** | Falls back to EC2 IP if `APP_DOMAIN` not set |
+
+---
+
+## 🚀 6. CI/CD Pipeline

+```
+
+### Key Features
+
+| Feature | Description | Benefit |
+|---------|-------------|---------|
+| **OIDC Auth** | Keyless AWS access | No credential rotation |
+| **SSM Deployment** | SSH-less server access | No Port 22 exposure |
+| **Gateway Pattern** | Nginx reverse proxy | Environment-agnostic builds |
+| **Base64 Encoding** | Safe secret transmission | Prevents injection attacks |
+| **Bootstrap Detection** | Auto-rebuild missing images | Self-healing infrastructure |
+| **Manual Triggers** | Force rebuild via workflow_dispatch | Control over secret changes |
+
+### Branch Strategy
+
+| Branch | Environment | Image Tag | Use Case |
+|--------|-------------|-----------|----------|
+| `main` | Production | `prod-latest` | Customer releases |
+| `DEV` | Development | `dev-latest` | Feature development |
+| `QA` | QA/Testing | `qa-latest` | Quality assurance |
+| `PREPROD` | Pre-Production | `preprod-latest` | Final validation |
+
+---
+
+## 📦 7. Deployment Architecture
+
+### Zero-Downtime Deployment
+
+1. **Build**: Docker images pushed to ECR with dual tags (`env-latest` + `git-sha`)
+2. **Infrastructure**: Terraform provisions/updates EC2
+3. **Deploy**: SSM executes remote deployment with Base64 configs
+4. **Validation**: Automated polling ensures container startup
+
+**Safety Features:**
+- 🔒 **Immutable Infrastructure**: Versioned Docker images
+- 🔄 **Rollback Ready**: Git SHA tags enable instant rollback
+- 📊 **Observable**: SSM output captured on failure
+- ⚡ **Fast**: Conditional builds skip unchanged services
+
+---
+
+## 🤝 8. Maintenance & Operations
+
+### Monitoring
+- GitHub Actions logs show deployment progress
+- Final step displays Public IP summary
+- SSM command output captured on failures
+
+### Infrastructure Management
+- Managed via Terraform in `./terraform`
+- Always run `terraform plan` before pushing
+- State file committed to repository
+
+### Live Logs
+```bash
+aws ssm send-command \
+  --instance-ids "$INSTANCE_ID" \
+  --document-name "AWS-RunShellScript" \
+  --parameters "commands=['sudo docker compose logs -f']"
+```

+# Domain Configuration with Cloudflare SSL
+
+Complete guide to setting up custom domains with free Cloudflare SSL certificates.
+
+---
+
+## Overview
+
+Your application supports custom domains via GitHub Secrets with **automatic Cloudflare SSL integration**. Users see HTTPS without any certificate management on your server.
+
+---
+
+## Setup Instructions
+
+### 1. Add Domain Secret to GitHub
+
+1. Go to your GitHub repository
+2. Navigate to **Settings** → **Secrets and variables** → **Actions**
+3. Click **"New repository secret"**
+4. Add:
+   - **Name**: `APP_DOMAIN`
+   - **Value**: `nexgensis-assignment.rohitverma.social`
+
+### 2. Configure Cloudflare
+
+#### A. Add DNS Record
+Point your domain to the EC2 instance:
+
+```
+Type: A Record
+Name: nexgensis-assignment (or @)
+Value: <EC2_PUBLIC_IP>
+TTL: Auto (or 300)
+```
+
+#### B. Enable SSL (Flexible Mode)
+1. Go to **Cloudflare Dashboard**
+2. Select your domain
+3. Navigate to: **SSL/TLS** → **Overview**
+4. Set encryption mode to: **Flexible**
+
+**Why Flexible?**
+- Cloudflare provides free SSL certificate
+- Your server uses simple HTTP
+- Users see HTTPS with green padlock 🔒
+- Zero certificate management needed
+
+### 3. Deploy
+
+Push code or trigger GitHub Actions workflow manually.
+
+**The workflow automatically:**
+1. Reads `APP_DOMAIN` secret
+2. Replaces `DOMAIN_PLACEHOLDER` in nginx.conf
+3. Deploys updated configuration to EC2
+
+**Fallback**: If `APP_DOMAIN` is not set, uses EC2 IP address.
+
+---
+
+## How It Works
+
+### Architecture
+
+```
+User Browser (HTTPS) 🔒
+    ↓
+Cloudflare (Free SSL Certificate)
+    ↓
+Your Server (HTTP on Port 80)
+    ↓
+Nginx Gateway → Backend/Frontend
+```
+
+### nginx.conf Template (Repository)
+```nginx
+server {
+    listen 80;
+    server_name DOMAIN_PLACEHOLDER;
+    # ... proxy configuration
+}
+```
+
+### Workflow Replacement Logic
+```bash
+# Read domain from GitHub Secret
+DOMAIN="${{ secrets.APP_DOMAIN }}"
+
+# Replace placeholder with actual domain
+sed "s|DOMAIN_PLACEHOLDER|$DOMAIN|g" nginx.conf > /tmp/nginx.conf
+
+# Encode and deploy
+ENCODED_NGINX=$(base64 -w 0 < /tmp/nginx.conf)
+```
+
+### Deployed nginx.conf (EC2)
+```nginx
+server {
+    listen 80;
+    server_name nexgensis-assignment.rohitverma.social;
+    # ... proxy configuration
+}
+```
+
+---
+
+## Testing
+
+### Test Domain Replacement Locally
+```bash
+sed "s|DOMAIN_PLACEHOLDER|your-domain.com|g" nginx.conf
+```
+
+### Verify DNS Propagation
+```bash
+dig nexgensis-assignment.rohitverma.social
+```
+
+### Check Deployed Configuration
+```bash
+docker exec nexgensis-gateway cat /etc/nginx/nginx.conf
+```
+
+---
+
+## Troubleshooting
+
+### Domain Not Resolving
+**Symptoms**: Cannot access domain
+**Solutions**:
+- Check DNS propagation: `dig your-domain.com`
+- Verify A record points to correct EC2 IP
+- Wait 5-10 minutes for DNS propagation
+
+### Error 521 (Web Server Down)
+**Symptoms**: Cloudflare shows "Web server is down"
+**Solutions**:
+- Verify EC2 instance is running
+- Check Security Group allows port 80
+- Ensure Docker containers are running: `docker ps`
+- Set Cloudflare SSL mode to **Flexible**
+
+### Nginx Not Using Domain
+**Symptoms**: Domain not recognized by nginx
+**Solutions**:
+- Verify `APP_DOMAIN` secret is set in GitHub
+- Check deployed nginx.conf (see command above)
+- Restart nginx: `docker restart nexgensis-gateway`
+
+### 502 Bad Gateway
+**Symptoms**: Nginx returns 502 error
+**Solutions**:
+- Check backend/frontend containers: `docker ps`
+- View nginx logs: `docker logs nexgensis-gateway`
+- View backend logs: `docker logs nexgensis-backend`
+- Verify Docker network connectivity
+
+---
+
+## Benefits of Cloudflare SSL
+
+✅ **Free SSL Certificate** - No cost for HTTPS  
+✅ **Auto-Renewal** - Cloudflare manages certificates  
+✅ **Zero Configuration** - No Certbot or Let's Encrypt needed  
+✅ **Works with Docker** - No host-level certificate installation  
+✅ **CDN Included** - Faster global performance  
+✅ **DDoS Protection** - Built-in security features  
+
+---
+
+## Security Note
+
+**Flexible SSL Mode** encrypts traffic between users and Cloudflare, but uses HTTP between Cloudflare and your server.
+
+**This is acceptable because:**
+- Cloudflare's network is trusted
+- Your server is in a private VPC
+- Most attacks target user → CDN connection (encrypted)
+- Cloudflare provides DDoS protection
+
+**For maximum security**, you can later upgrade to **Full (strict)** mode with a proper SSL certificate using Certbot.
+
+---
+
+## Next Steps
+
+1. ✅ Add `APP_DOMAIN` secret in GitHub
+2. ✅ Configure Cloudflare DNS A record
+3. ✅ Set Cloudflare SSL to Flexible mode
+4. ✅ Deploy via GitHub Actions
+5. ✅ Access: `https://your-domain.com` 🎉

+## 🏗 Modular Architecture Overview
+
+Our infrastructure is split into three core modules for professional isolation:
+- **`modules/vpc`**: Networking foundation.
+- **`modules/iam`**: Access control rules.
+- **`modules/ec2`**: Compute resources.
+
+### Example Module Configuration
+```hcl
+module "ec2" {
+  source           = "./modules/ec2"
+  frontend_repo    = var.frontend_repo_name
+  backend_repo     = var.backend_repo_name
+  frontend_image_tag = var.frontend_image_tag
+}
+```
+
+---
+
+## 🛡️ Idempotency & Collision Handling
+
+The infrastructure is designed to be **self-healing** and **collision-resistant**.
+
+### A. Automatic Resource Reuse
+Terraform inherently avoids recreating resources that are already part of its tracking state. 
+- If you run `apply` twice, Terraform detects no changes and skips the creation.
+- **Tip**: To maintain this behavior across different environments, ensure you are using a consistent state (S3 backend is the production standard).
+
+### B. Collision Protection (`name_prefix`)
+To prevent fatal "Resource Already Exists" errors (common with IAM roles and Security Groups), we use `name_prefix` instead of static names.
+```hcl
+# Instead of name = "fixed-name"
+name_prefix = "nexgensis-sg-"
+```
+If a conflicting resource is found in your AWS account that isn't in your current state, Terraform will automatically append a unique suffix to the new resource, allowing the deployment to proceed without failure.
+
+---
+
+## 🎡 Lifecycle in CI/CD
+
+Controlled via the **Unified CI/CD Pipeline (`cicd.yaml`)**:
+```bash
+# The lifecycle steps
+1. Build Images
+2. terraform apply
+3. scp docker-compose.yml
+4. remote execute 'up -d'
+```
+
+---
+
+## 🚀 Local Administration
+
+To manage locally for testing or debugging:
+
+### 🛠 Setup & Launch
+```bash
+terraform init
+cp terraform.tfvars.example terraform.tfvars
+# Edit terraform.tfvars then:
+terraform apply -auto-approve
+```
+
+---
+
+## 🛡 Network & Security Rules
+The following ports are mandatory for the application to function:
+- **Port 80**: Public Web Traffic.
+- **Port 22**: Administrative (SSH) Access.
