2. Click Add Node
3. Select the target cluster
4. Configure node details:
   • Node name and role (Server/Agent)
   • SSH connection details
   • Node IP address
5. Click Add Node

Managing SSH Configurations

Roadmap

• Implement actual K3sup backend integration
• Add real SSH key-based authentication
• Real-time cluster status monitoring
• Cluster logs viewer
• Multi-user support with roles
• API endpoints for external integrations
• Kubernetes resources management
• Helm charts deployment
• Cluster backup and restore
• Monitoring and alerting

Security Considerations

⚠️ Important: This is a development/demo version. For production use:

1. Implement proper authentication (JWT, OAuth, etc.)
2. Use SSH keys instead of passwords
3. Encrypt sensitive data
4. Use HTTPS
5. Implement rate limiting
6. Add CSRF protection
7. Validate all inputs
8. Use environment variables for configuration
