## 2. Domain Setup (bharathtrucks.com)

### Cloudflare Configuration
1. Add domain to Cloudflare (free plan)
2. Update nameservers at registrar to Cloudflare's
3. DNS Records:

| Type | Name | Value | Proxy |
|------|------|-------|-------|
| A | @ | `<VPS_IP>` | Proxied ☁️ |
| A | www | `<VPS_IP>` | Proxied ☁️ |
| CNAME | api | @ | Proxied ☁️ |

4. SSL: Full (Strict) mode
5. Page Rules:
   - `*.bharathtrucks.com/public/*` → Cache Everything, Edge TTL 1 month
   - `bharathtrucks.com/` → Cache Level: Standard

---

## 3. Dockerfile

```dockerfile
FROM node:20-alpine

WORKDIR /app

COPY webapp/package*.json ./
RUN npm ci --only=production

COPY webapp/src ./src

ENV NODE_ENV=production
ENV PORT=3000

EXPOSE 3000

HEALTHCHECK --interval=30s --timeout=3s --start-period=5s \
  CMD wget --no-verbose --tries=1 --spider http://localhost:3000/health || exit 1

CMD ["node", "src/server.js"]
```

---

## 4. Docker Compose (Local Development)

```yaml
version: '3.8'

services:
  app:
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - "3000:3000"
    env_file:
      - webapp/.env
    volumes:
      - ./webapp/src:/app/src
    restart: unless-stopped
```

---

## 5. Coolify Deployment Steps

### Initial Setup
1. SSH into Hostinger VPS
2. Install Coolify: `curl -fsSL https://cdn.coollabs.io/coolify/install.sh | bash`
3. Access Coolify dashboard at `http://<VPS_IP>:8000`
4. Configure domain in Coolify settings

### App Deployment
1. **Source:** Connect GitHub/GitLab repo (or use Git URL)
2. **Build Pack:** Dockerfile
3. **Port:** 3000
4. **Domain:** bharathtrucks.com
5. **Environment Variables:** Add all from `.env.example`
6. **Health Check:** `/health`
7. **Auto Deploy:** On push to `main` branch

### Environment Variables in Coolify
```
NODE_ENV=production
PORT=3000
SUPABASE_URL=https://xxx.supabase.co
SUPABASE_ANON_KEY=eyJ...
SUPABASE_SERVICE_KEY=eyJ...
APP_URL=https://bharathtrucks.com
SESSION_SECRET=<generate-random-64-char>
RATE_LIMIT_BIDS_PER_DAY=5
```

---

## 6. Supabase Setup

### Project Configuration
1. Create project at supabase.com (region: Mumbai)
2. Note: Project URL + anon key + service role key
3. Enable Phone Auth (OTP provider)
4. Configure SMS provider (Twilio or MSG91)

### Auth Settings
- Phone OTP enabled
- OTP expiry: 5 minutes
- Rate limit: 5 OTP requests per hour per number
- Disable email confirmation (phone-first)

### Database Setup
- Run schema SQL from `docs/architecture/DATABASE_SCHEMA.md`
- Enable RLS on all tables
- Create indexes as specified

### Storage Buckets
| Bucket | Purpose | Public |
|--------|---------|--------|
| `avatars` | Profile photos | Yes |
| `documents` | License, RC uploads | No |
| `load-images` | Load/material photos | Yes |

---

## 7. CI/CD Pipeline

### GitHub Actions (Optional)
```yaml
name: Deploy
on:
  push:
    branches: [main]

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Trigger Coolify Webhook
        run: |
          curl -X POST "${{ secrets.COOLIFY_WEBHOOK_URL }}"
```

### Simpler: Coolify Auto-Deploy
Coolify watches the repo and auto-deploys on push to `main`. No CI/CD config needed.

---

## 8. Monitoring & Logging

| Tool | Purpose | Cost |
|------|---------|------|
| Coolify Dashboard | Container status, resource usage | Free |
| Cloudflare Analytics | Traffic, cache hit rate | Free |
| Supabase Dashboard | DB metrics, auth logs | Free |
| UptimeRobot | Uptime monitoring, alerts | Free (50 monitors) |

### Health Check Endpoint
```javascript
app.get('/health', (req, res) => {
  res.status(200).json({ status: 'ok', timestamp: Date.now() });
});
```

### Log Strategy
- Application logs: stdout (Docker captures)
- Access logs: Morgan middleware (combined format)
- Error logs: Structured JSON to stdout
- View in Coolify dashboard → Container logs

---

## 9. Backup Strategy

| What | How | Frequency |
|------|-----|-----------|
| Database | Supabase automatic backups | Daily (Pro plan) |
| Code | Git repository | Every push |
| Environment | Documented in `.env.example` | Manual |
| Uploads | Supabase Storage (managed) | Automatic |

---

## 10. Security Hardening

### VPS Level
- UFW firewall: allow 22, 80, 443 only
- Fail2ban for SSH brute-force protection
- SSH key-only auth (disable password)
- Automatic security updates

### Application Level
- Helmet.js security headers
- CORS restricted to bharathtrucks.com
- Rate limiting (express-rate-limit)
- Input sanitization
- httpOnly cookies for sessions
- CSP headers (Content Security Policy)

### Cloudflare Level
- DDoS protection (automatic)
- Bot management (free tier)
- WAF rules (basic)
- SSL enforcement

---

## 11. Scaling Triggers

| Metric | Threshold | Action |
|--------|-----------|--------|
| CPU | >80% sustained | Upgrade VPS |
| RAM | >85% | Upgrade VPS |
| Response time | >2s average | Add caching/optimize |
| Users | >5000 | Supabase Pro + Redis |
| Traffic | >10K req/min | Multiple containers |

---

## 12. Cost Estimate (Phase 1)

| Service | Plan | Monthly Cost |
|---------|------|-------------|
| Hostinger VPS | KVM 2 (4vCPU/8GB) | ~₹800/month |
| Supabase | Free tier | ₹0 |
| Cloudflare | Free plan | ₹0 |
| Domain | bharathtrucks.com | ~₹800/year |
| UptimeRobot | Free | ₹0 |
| **Total** | | **~₹900/month** |
