### Key Features
#### **Host Network Mode**
#### **Kubernetes Deployment with hostNetwork**
```yaml
spec:
hostNetwork: true # Direct access to host's Mycelium IPv6 interface
template:
spec:
hostNetwork: true # Direct IPv6 interface binding
containers:
- name: nginx
image: nginx:alpine
ports:
- containerPort: 80 # Standard web port
hostPort: 80 # Direct host binding
```
#### **LoadBalancer with IPv6 External IPs**
#### **Dynamic IPv6 Discovery**
The `update-content.sh` script automatically discovers Mycelium IPv6 addresses from your cluster:
```bash
# Run the script to update content with current IPv6 addresses
./update-content.sh
# The script will:
# 1. Query kubectl for cluster node IPv6 addresses
# 2. Generate HTML with dynamic address discovery
# 3. Update the ConfigMap automatically
# 4. Show website content with current cluster state
```
#### **Custom Website Content**
The deployment includes a professional website with:
- Modern HTML design with Mycelium Cloud branding
- Responsive layout with gradient backgrounds
- Interactive IPv6 address detection
- Real-time timestamp updates
- Professional web interface
#### **Content Management**
```yaml
spec:
type: LoadBalancer
externalIPs:
- "51d:3596:6cc3:81e7:ff0f:d546:3737:4c8c" # All 6 cluster IPv6 addresses
# ... complete list of IPv6 addresses
ports:
- port: 80
targetPort: 80
volumes:
- name: html-content
configMap:
name: mycelium-website-content # Custom website content
- name: nginx-config
configMap:
name: mycelium-nginx-config # nginx configuration
```
#### **Multi-Node Scaling**
```yaml
spec:
replicas: 3 # Distribute across different cluster nodes
nodeSelector: {} # Allow any node for load balancing
```
## 🌟 Direct IPv6 Access Benefits
## 📊 Load Balancing Benefits
### **Traffic Distribution**
- **Across Nodes**: 3 pods spread across different cluster nodes
- **Health Monitoring**: Kubernetes automatically routes around failed pods
- **No Single Point of Failure**: Multiple nginx instances serve traffic
### **Direct Interface Binding**
- **hostNetwork: true**: Pod directly binds to host network interface
- **IPv6 Address Access**: Gets Mycelium IPv6 address from host node
- **Simplified Architecture**: No service layer needed for IPv6 access
- **Direct Connectivity**: External clients connect directly to pod
### **Performance Advantages**
- **Reduced Latency**: Traffic routes to nearest healthy pod
- **Higher Throughput**: Multiple nginx instances handle more concurrent requests
- **Fault Tolerance**: Automatic failover if a pod or node fails
- **Zero Latency**: Direct interface binding, no service proxy overhead
- **Full IPv6 Support**: Direct access to Mycelium IPv6 addresses
- **Simple Deployment**: Single pod with hostNetwork configuration
- **Production Ready**: Standard nginx configuration with health endpoints
### **Scalability**
### **Global Accessibility**
```bash
# Scale up if you need more capacity
kubectl scale deployment nginx-mycelium --replicas=5
# Scale down to save resources
kubectl scale deployment nginx-mycelium --replicas=1
# Access directly via any Mycelium IPv6 address
curl http://[552:5984:2d97:72dc:ff0f:39ef:6ec:a48c]:80
```
## 🔧 Testing & Verification
### **Basic Connectivity Test**
### **✅ CONFIRMED: IPv6 Connectivity Test**
```bash
# Test from your machine (requires Mycelium client)
curl -6 http://[51d:3596:6cc3:81e7:ff0f:d546:3737:4c8c]:80
# ✅ VERIFIED: Direct IPv6 connectivity working!
curl -v http://[552:5984:2d97:72dc:ff0f:39ef:6ec:a48c]:80
# Test with IPv6 resolution

# < HTTP/1.1 200 OK (or 404 if serving default content)
```
### **Load Balancing Test**
### **🎯 Pod Status Verification**
```bash
# Check which pods are running where
kubectl get pods -l app=nginx-mycelium -o wide
# Check pod status and location
kubectl get pods -l app=mycelium-website -o wide
# Test multiple requests to see load distribution
for i in {1..10}; do curl -s http://[51d:3596:6cc3:81e7:ff0f:d546:3737:4c8c]:80 | grep -o "Node: [^<]*"; done
# Expected output shows:
# NAME READY STATUS NODE
# mycelium-website-xxxx-xxxx 1/1 Running kc22haven612worker1
# Get the IPv6 address of the pod's node
NODE_NAME=$(kubectl get pod -l app=mycelium-website -o jsonpath='{.items[0].spec.nodeName}')
MYCELIUM_IP=$(kubectl get node $NODE_NAME -o jsonpath='{.status.addresses[?(@.type=="InternalIP")].address}')
echo "Pod running on: $NODE_NAME with IPv6: $MYCELIUM_IP"
```
### **Health Monitoring**
### **🌐 Direct IPv6 Access Test**
```bash
# Check service endpoints
kubectl get endpoints nginx-mycelium-service
# Test from multiple IPv6 addresses (all should work):
curl http://[51d:3596:6cc3:81e7:ff0f:d546:3737:4c8c]:80

curl http://[538:964a:a1e1:4057:ff0f:63c7:960b:7c27]:80
# Monitor pod status
kubectl get pods -l app=nginx-mycelium -w
# All should return the custom Mycelium Cloud website HTML
```
# Check nginx logs
kubectl logs -l app=nginx-mycelium --tail=10
### **🏥 Health Endpoint Test**
```bash
# Test the health endpoint
kubectl exec pod/mycelium-website-xxxx-xxxx -- curl -s http://localhost:8080/health
# Expected output: "healthy"
```
### **📊 Content Verification**
```bash
# Check that custom content is being served
curl -s http://[552:5984:2d97:72dc:ff0f:39ef:6ec:a48c]:80 | head -10
# Should show the custom Mycelium Cloud website HTML with:
# - <title>Mycelium Cloud - Globally Accessible Website</title>
# - Professional styling and branding
```
### **🔍 Network Interface Verification**
```bash
# Verify hostNetwork binding
kubectl exec pod/mycelium-website-xxxx-xxxx -- ip addr show | grep inet6
# Should show the Mycelium IPv6 address bound to the pod
# Example: inet6 552:5984:2d97:72dc:ff0f:39ef:6ec:a48c/64 scope global
```
### **📈 Load Testing**
```bash
# Test concurrent requests
for i in {1..5}; do
curl -s http://[552:5984:2d97:72dc:ff0f:39ef:6ec:a48c]:80 > /dev/null &
