 # Docker Deployment Guide
 ## Quick Start
 Deploy the complete SchoolCompare stack (PostgreSQL + FastAPI + Next.js) with one command:
 ```bash
 docker-compose up -d
 ```
 This will start:
 - **PostgreSQL** on port 5432 (database)
 - **FastAPI** on port 8000 (backend API)
 - **Next.js** on port 3000 (frontend)
 ## Service Details
 ### PostgreSQL Database
 - **Port**: 5432
 - **Container**: `schoolcompare_db`
 - **Credentials**:
  - User: `schoolcompare`
  - Password: `schoolcompare`
  - Database: `schoolcompare`
 - **Volume**: `postgres_data` (persistent storage)
 ### FastAPI Backend
 - **Port**: 8000 → 80 (container)
 - **Container**: `schoolcompare_backend`
 - **Built from**: Root `Dockerfile`
 - **API Endpoint**: http://localhost:8000/api
 - **Health Check**: http://localhost:8000/api/data-info
 ### Next.js Frontend
 - **Port**: 3000
 - **Container**: `schoolcompare_nextjs`
 - **Built from**: `nextjs-app/Dockerfile`
 - **URL**: http://localhost:3000
 - **Connects to**: Backend via internal network
 ## Commands
 ### Start all services
 ```bash
 docker-compose up -d
 ```
 ### View logs
 ```bash
 # All services
 docker-compose logs -f
 # Specific service
 docker-compose logs -f nextjs
 docker-compose logs -f backend
 docker-compose logs -f db
 ```
 ### Check status
 ```bash
 docker-compose ps
 ```
 ### Stop all services
 ```bash
 docker-compose down
 ```
 ### Rebuild after code changes
 ```bash
 # Rebuild and restart specific service
 docker-compose up -d --build nextjs
 # Rebuild all services
 docker-compose up -d --build
 ```
 ### Clean restart (remove volumes)
 ```bash
 docker-compose down -v
 docker-compose up -d
 ```
 ## Initial Database Setup
 After first start, you may need to initialize the database:
 ```bash
 # Enter the backend container
 docker exec -it schoolcompare_backend bash
 # Run migrations or data loading
 python -m backend.data_loader
 ```
 ## Accessing Services
 Once running:
 - **Frontend**: http://localhost:3000
 - **Backend API**: http://localhost:8000/api
 - **API Docs**: http://localhost:8000/docs (Swagger UI)
 - **Database**: localhost:5432 (use any PostgreSQL client)
 ## Environment Variables
 Create a `.env` file in the root directory to customize:
 ```env
 # Database
 POSTGRES_USER=schoolcompare
 POSTGRES_PASSWORD=your_secure_password
 POSTGRES_DB=schoolcompare
 # Backend
 DATABASE_URL=postgresql://schoolcompare:your_secure_password@db:5432/schoolcompare
 # Frontend (for client-side access)
 NEXT_PUBLIC_API_URL=http://localhost:8000/api
 ```
 Then run:
 ```bash
 docker-compose up -d
 ```
 ## Troubleshooting
 ### Backend not connecting to database
 ```bash
 # Check database health
 docker-compose ps
 # View backend logs
 docker-compose logs backend
 # Restart backend
 docker-compose restart backend
 ```
 ### Frontend not connecting to backend
 ```bash
 # Check backend health
 curl http://localhost:8000/api/data-info
 # Check Next.js environment variables
 docker exec schoolcompare_nextjs env | grep API
 ```
 ### Port already in use
 ```bash
 # Change ports in docker-compose.yml
 # For example, change "3000:3000" to "3001:3000"
 ```
 ### Rebuild from scratch
 ```bash
 docker-compose down -v
 docker system prune -a
 docker-compose up -d --build
 ```
 ## Production Deployment
 For production, update the following:
 1. **Use secure passwords** in `.env` file
 2. **Configure reverse proxy** (Nginx) in front of Next.js
 3. **Enable HTTPS** with SSL certificates
 4. **Set production environment variables**:
   ```env
   NODE_ENV=production
   POSTGRES_PASSWORD=<strong-password>
   ```
 5. **Backup database** regularly:
   ```bash
   docker exec schoolcompare_db pg_dump -U schoolcompare schoolcompare > backup.sql
   ```
 ## Network Architecture
 ```
 Internet
    ↓
 Next.js (port 3000) ← User browsers
    ↓ (internal network)
 FastAPI (port 8000) ← API calls
    ↓ (internal network)
 PostgreSQL (port 5432) ← Data queries
 ```
 All services communicate via the `schoolcompare-network` Docker network.

 # Deployment Guide
 This guide covers deployment options for the SchoolCompare Next.js application.
 ## Deployment Options
 ### Option 1: Vercel (Recommended for Next.js)
 Vercel is the easiest and most optimized platform for Next.js applications.
 #### Steps:
 1. **Install Vercel CLI**:
   ```bash
   npm install -g vercel
   ```
 2. **Login to Vercel**:
   ```bash
   vercel login
   ```
 3. **Deploy**:
   ```bash
   vercel --prod
   ```
 4. **Configure Environment Variables** in Vercel dashboard:
   - `NEXT_PUBLIC_API_URL`: Your FastAPI endpoint (e.g., `https://api.schoolcompare.co.uk/api`)
   - `FASTAPI_URL`: Same as above for server-side requests
 #### Benefits:
 - Automatic HTTPS
 - Global CDN
 - Zero-config deployment
 - Automatic preview deployments
 - Built-in analytics
 ---
 ### Option 2: Docker (Self-hosted)
 Deploy using Docker containers for full control.
 #### Prerequisites:
 - Docker 20+
 - Docker Compose 2+
 #### Steps:
 1. **Build Docker Image**:
   ```bash
   docker build -t schoolcompare-nextjs:latest .
   ```
 2. **Run with Docker Compose**:
   ```bash
   # Create .env file with production variables
   echo "NEXT_PUBLIC_API_URL=https://api.schoolcompare.co.uk/api" > .env
   echo "FASTAPI_URL=http://backend:8000/api" >> .env
   # Start services
   docker-compose up -d
   ```
 3. **Verify Deployment**:
   ```bash
   curl http://localhost:3000
   ```
 #### Environment Variables:
 - `NEXT_PUBLIC_API_URL`: Public API endpoint (client-side)
 - `FASTAPI_URL`: Internal API endpoint (server-side)
 - `NODE_ENV`: `production`
 ---
 ### Option 3: PM2 (Node.js Process Manager)
 Deploy directly on a Node.js server using PM2.
 #### Prerequisites:
 - Node.js 24+
 - PM2 (`npm install -g pm2`)
 #### Steps:
 1. **Build Application**:
   ```bash
   npm run build
   ```
 2. **Create PM2 Ecosystem File** (`ecosystem.config.js`):
   ```javascript
   module.exports = {
     apps: [{
       name: 'schoolcompare-nextjs',
       script: 'npm',
       args: 'start',
       cwd: '/path/to/nextjs-app',
       instances: 'max',
       exec_mode: 'cluster',
       env: {
         NODE_ENV: 'production',
         PORT: 3000,
         NEXT_PUBLIC_API_URL: 'https://api.schoolcompare.co.uk/api',
         FASTAPI_URL: 'http://localhost:8000/api',
       },
     }],
   };
   ```
 3. **Start with PM2**:
   ```bash
   pm2 start ecosystem.config.js
   pm2 save
   pm2 startup
   ```
 ---
 ### Option 4: Nginx Reverse Proxy
 Use Nginx as a reverse proxy in front of Next.js.
 #### Nginx Configuration:
 ```nginx
 server {
    listen 80;
    server_name schoolcompare.co.uk;
    # Redirect to HTTPS
    return 301 https://$server_name$request_uri;
 }
 server {
    listen 443 ssl http2;
    server_name schoolcompare.co.uk;
    # SSL Configuration
    ssl_certificate /etc/ssl/certs/schoolcompare.crt;
    ssl_certificate_key /etc/ssl/private/schoolcompare.key;
    # Security Headers
    add_header X-Frame-Options "SAMEORIGIN" always;
    add_header X-Content-Type-Options "nosniff" always;
    add_header X-XSS-Protection "1; mode=block" always;
    # Proxy to Next.js
    location / {
        proxy_pass http://localhost:3000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
    # Proxy to FastAPI
    location /api/ {
        proxy_pass http://localhost:8000;
        proxy_http_version 1.1;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
    # Cache static files
    location /_next/static/ {
        proxy_pass http://localhost:3000;
        add_header Cache-Control "public, max-age=31536000, immutable";
    }
 }
 ```

   ```
 2. **Test Routes**:
   - Home: `https://schoolcompare.co.uk/`
   - School Page: `https://schoolcompare.co.uk/school/100001`
   - Compare: `https://schoolcompare.co.uk/compare`
   - Rankings: `https://schoolcompare.co.uk/rankings`
 3. **Check SEO**:
   - Sitemap: `https://schoolcompare.co.uk/sitemap.xml`
   - Robots: `https://schoolcompare.co.uk/robots.txt`
 4. **Performance Audit**:
   - Run Lighthouse in Chrome DevTools
   - Target scores: 90+ for Performance, Accessibility, Best Practices, SEO
 ---
 ## Monitoring
 ### Recommended Tools:
 - **Vercel Analytics** (if using Vercel)
 - **Sentry** for error tracking
 - **Google Analytics** for user analytics
 - **Uptime Robot** for uptime monitoring
 ### Health Check Endpoint:
 The application automatically serves health data at the root route.
 ---
 ## Rollback Procedure
 ### Vercel:
 ```bash
 vercel rollback
 ```
 ### Docker:
 ```bash
 docker-compose down
 docker-compose up -d --force-recreate
 ```
 ### PM2:
 ```bash
 pm2 stop schoolcompare-nextjs
 # Restore previous build
 pm2 start schoolcompare-nextjs
 ```
 ---
 ## Troubleshooting
 ### Issue: API requests failing
 - **Solution**: Check `NEXT_PUBLIC_API_URL` and `FASTAPI_URL` environment variables
 - **Verify**: FastAPI backend is accessible from Next.js container/server
 ### Issue: Build fails
 - **Solution**: Check Node.js version (requires 24+)
 - **Clear cache**: `rm -rf .next node_modules && npm install && npm run build`
 ### Issue: Slow page loads
 - **Solution**: Enable caching in API calls
 - **Check**: Network latency to FastAPI backend
 - **Verify**: CDN is serving static assets
 ---
 ## Security Considerations
 - ✅ HTTPS enabled
 - ✅ Security headers configured (X-Frame-Options, CSP, etc.)
 - ✅ API keys in environment variables (never in code)
 - ✅ CORS properly configured
 - ✅ Rate limiting on API endpoints
 - ✅ Regular security updates
 - ✅ Dependency vulnerability scanning
