     }
   }

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)
