Quick Start

1. Clone the repository:

   git clone https://github.com/bufanoc/ovn-web-manager.git
   cd ovn-web-manager

2. Make the installation script executable:

   chmod +x start.sh

3. Run the installation script:

   ./start.sh

The script will automatically:

• Install all required system packages
• Set up OVN and its dependencies
• Configure the Python backend environment
• Build and serve the React frontend
• Start all necessary services

Once completed, the application will be accessible at:

• Frontend: http://<server-ip>:3000
• Backend API: http://<server-ip>:5000

Security Notes

• The application runs services on ports 3000 (frontend) and 5000 (backend)
• Make sure to configure your firewall to allow access to these ports
• Consider setting up HTTPS for production use
• Default configuration listens on all network interfaces

Troubleshooting

If you encounter issues:

1. Check service status:

   systemctl status openvswitch-switch
   systemctl status ovn-northd
   systemctl status ovn-controller

2. View application logs:

   tail -f frontend.log
   tail -f backend.log

3. Check OVN database connectivity:

   sudo ovn-nbctl show
   sudo ovn-sbctl show
