## Workflow

### Basic VPS Setup

1. **Connect to VPS:**

   ```json
   {
     "tool": "ssh_connect",
     "args": {
       "host": "your-vps-ip",
       "username": "root",
       "password": "your-password"
     }
   }
   ```

2. **Initialize VPS:**

   ```json
   {
     "tool": "vps_initialize",
     "args": {
       "services": {
         "nodejs": true,
         "pm2": true,
         "nginx": true
       }
     }
   }
   ```

3. **Setup Nginx:**

   ```json
   {
     "tool": "nginx_setup",
     "args": {
       "domain": "yourdomain.com",
       "port": 3000,
       "ssl": true
     }
   }
   ```

4. **Setup CI/CD:**
   ```json
   {
     "tool": "github_cicd_setup",
     "args": {
       "repoUrl": "https://github.com/username/repo.git",
       "deployPath": "/opt/deployments/myapp"
     }
   }
   ```

### GitHub CI/CD Instructions

After running the `github_cicd_setup` tool, you'll receive:

1. **Deploy Key**: Add to your GitHub repository's Deploy Keys
2. **GitHub Secrets**: Add to your repository's Actions secrets
3. **Workflow File**: Add to `.github/workflows/deploy.yml`

The generated workflow will:

- Trigger on pushes to main/master branch
- Run tests (if available)
- Build the application (if build script exists)
- Deploy to your VPS automatically

## Security Features

- **Firewall Configuration**: Automatic UFW setup with secure defaults
- **SSL Certificates**: Automated Let's Encrypt certificate generation
- **SSH Key Management**: Secure deploy key generation
- **Process Isolation**: Optional deploy user creation

## Logging

Logs are written to:

- `logs/combined.log`: All log levels
- `logs/error.log`: Error logs only
- Console: Formatted output with colors

Log levels: `error`, `warn`, `info`, `debug`

## Configuration

The server can be configured through environment variables:

- `LOG_LEVEL`: Set logging level (default: 'info')
- `PORT`: Server port (if running standalone)

## Troubleshooting

### Common Issues

1. **SSH Connection Failed**
   - Verify IP address and credentials
   - Check firewall settings
   - Ensure SSH service is running

2. **SSL Certificate Issues**
   - Verify domain DNS points to server
   - Check firewall allows HTTP/HTTPS
   - Ensure email is valid for Let's Encrypt

3. **Service Installation Failed**
   - Check system update status
   - Verify internet connectivity
   - Review error logs

### Debug Mode

Enable debug logging:

```bash
LOG_LEVEL=debug npm start
```

## Requirements

- Node.js 18+
- Fresh Ubuntu/Debian VPS
- Domain name (for SSL setup)
- GitHub repository (for CI/CD)
