A Next.js-based web interface for the ICOS Ecosystem that displays cluster topology and deployment information.

• ✅ Real-time Data: Connects directly to ICOS backend server
• ✅ Authentication: Secure login with real server credentials
• ✅ Topology Visualization: Interactive cluster topology graphs
• ✅ Universal Deployment: Works on any system with Docker
• ✅ Fallback Support: Graceful handling of connection issues

• Docker and Docker Compose installed
• VPN connection to the ICOS testbed (if required)
• Access to the ICOS backend server

1. Clone the repository:

   git clone <repository-url>
   cd <repository-folder>

2. Build and run with Docker:

   docker-compose up --build -d

3. Access the application:

   • Open your browser and go to http://127.0.0.1:3000
   • Login with your ICOS credentials

1. Install dependencies:

   npm install

2. Run in development mode:

   npm run dev

3. Access at http://localhost:3000

The application uses the following environment variables:

• NEXT_PUBLIC_CONTROLLER_ADDRESS: ICOS backend server address
• NEXT_PUBLIC_LIGHTHOUSE_ADDRESS: Lighthouse server address

The application connects directly to:

• Backend Server: http://10.160.3.20:32500
• API Endpoints:
  • Login: /api/v3/user/login
  • Resources: /api/v3/resource/
  • Deployments: /api/v3/deployment/

• Authentication: Direct connection to ICOS backend
• Topology Graph: D3.js-based visualization
• Data Fetching: Real-time API calls with fallback
• Error Handling: Graceful degradation

1. User logs in → Direct API call to backend
2. Token stored → Used for subsequent requests
3. Data fetched → Real-time cluster information
4. Graph rendered → Interactive topology display

1. Connection Refused: Check VPN connection and server availability
2. Authentication Failed: Verify credentials with backend team
3. No Data Displayed: Check API endpoints and token validity

View application logs:

docker-compose logs -f app

To update the application:

docker-compose stop
docker-compose rm -f
docker-compose up --build -d
