# QR Code Manager - Domain Setup Guide

## Option 1: Using Nginx Reverse Proxy (Recommended)

### 1. Install Nginx
```bash
sudo apt update
sudo apt install nginx
```

### 2. Create Nginx Configuration
```bash
sudo nano /etc/nginx/sites-available/qr.moto-adv.com
```

Add this configuration:
```nginx
server {
    listen 80;
    server_name qr.moto-adv.com;
    
    location / {
        proxy_pass http://localhost:8066;
        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;
        
        # Handle WebSocket connections if needed
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}
```

### 3. Enable the Site
```bash
sudo ln -s /etc/nginx/sites-available/qr.moto-adv.com /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl reload nginx
```

### 4. DNS Configuration
Make sure your domain `qr.moto-adv.com` points to your server's IP address:
- Add an A record: `qr.moto-adv.com -> YOUR_SERVER_IP`

## Option 2: Direct Docker Port Mapping

### Modify docker-compose.yml
```yaml
services:
  qr-manager:
    # ... other config
    ports:
      - "80:5000"  # Map port 80 directly to container
```

Then access via `http://qr.moto-adv.com` (without port number)

## Option 3: SSL/HTTPS Setup (Production)

### Using Certbot for Let's Encrypt SSL
```bash
sudo apt install certbot python3-certbot-nginx
sudo certbot --nginx -d qr.moto-adv.com
```

## Testing Your Setup

1. **Test locally first:**
   ```bash
   curl http://localhost:8066
   # Should redirect to /login
   ```

2. **Test domain (after DNS is configured):**
   ```bash
   curl -H "Host: qr.moto-adv.com" http://localhost:8066
   ```

3. **Access the dashboard:**
   - Open: http://qr.moto-adv.com (or http://localhost:8066)
   - Username: ske087
   - Password: Matei@123

## Current Working Credentials

✅ **Admin Login:**
- **Username:** `ske087`
- **Password:** `Matei@123`
- **URL:** http://localhost:8066/login

## Health Check
Your app includes a health endpoint: http://localhost:8066/health

## Troubleshooting

1. **Check container status:**
   ```bash
   docker compose ps
   docker compose logs qr-manager
   ```

2. **Check port binding:**
   ```bash
   netstat -tulpn | grep 8066
   ```

3. **Test internal connectivity:**
   ```bash
   docker exec -it qr-code-manager curl http://localhost:5000/health
   ```
