- **Professional**: Load balancing and technical details display

## 🔧 Technical Implementation Details

### Dynamic Discovery Command
```bash
kubectl get nodes -o jsonpath='{range .items[*]}{range .status.addresses[?(@.type=="InternalIP")]}{.address}{"\n"}{end}{end}' | grep -E '^[0-9a-f]+:[0-9a-f]+:[0-9a-f]+:[0-9a-f]+:[0-9a-f]+:[0-9a-f]+:[0-9a-f]+:[0-9a-f]+$'
```

### Deployment Architecture
```
User Request → Mycelium IPv6:30090 → Kubernetes NodePort → nginx Pod → Dynamic HTML
```

### Service Configuration
- **Type**: NodePort
- **Port**: 30090 (mapped to internal port 80)
- **Load Balancing**: Kubernetes distributes across 3 nginx pods
- **Nodes**: 6 Mycelium IPv6 addresses for global access

## 🚀 Dynamic Discovery Features

### Auto-Discovery Process
1. **IPv6 Discovery**: Script queries cluster nodes for Mycelium IPv6 addresses
2. **Content Generation**: Automatically generates HTML with discovered addresses
3. **ConfigMap Update**: Updates nginx content without pod restart needed
4. **Auto-refresh**: Website shows live cluster state every 30 seconds

### Benefits Over Static Configuration
- **🔄 Adaptive**: Automatically adapts to cluster changes
- **🛠️ Maintainable**: No manual address updates required
- **⚡ Resilient**: Works with any number of cluster nodes
- **🎯 Professional**: Shows real-time cluster information

## 📋 Usage Instructions

### Deploy the Website
```bash
cd myceliumcloud-examples/examples/nginx-mycelium
kubectl apply -f nginx-mycelium-deployment.yaml
