# nginx-nodeport - Mycelium Cloud NodePort Website Example
Complete, production-ready example for deploying a secure, globally accessible website on Mycelium Cloud using **NodePort** services.
## 🚀 Quick Start (One Command!)
**Start here if you want EVERYTHING done automatically:**
```bash
cd myceliumcloud-examples/examples/nginx-nodeport
./deploy-and-test.sh
```
That's it! This script will:
1. ✅ Deploy all resources (ConfigMaps, Deployment, Service)
2. ✅ Wait for pods to be ready
3. ✅ Verify service configuration
4. ✅ Update website content with current node information
5. ✅ Apply changes
6. ✅ Run comprehensive tests
7. ✅ Show you the access URL
**Output example:**
```
🎉 Deploy and Test Complete!
==================================
🌐 Access Information:
• URL: http://[552:5984:2d97:72dc:ff0f:39ef:6ec:a48c]:30091
• Node: kc22haven612worker1
To access from a machine with Mycelium installed:
curl -6 "http://[552:5984:2d97:72dc:ff0f:39ef:6ec:a48c]:30091/"
Or open in browser:
http://[552:5984:2d97:72dc:ff0f:39ef:6ec:a48c]:30091
```
---
## 📚 Available Scripts
### 1. `deploy-and-test.sh` - **RECOMMENDED** ⭐
**The ONE script to do everything from scratch**
```bash
./deploy-and-test.sh
```
Does everything: deploy, test, configure, and show results.
### 2. `update-content.sh` - Content Update
**Updates website content with current cluster state**
```bash
./update-content.sh
kubectl rollout restart deployment/nginx-nodeport
```
Updates the ConfigMap and restarts pods to apply changes.
---
## 🔧 Manual Deployment (If You Prefer)
If you want to do it step-by-step yourself:
```bash
# 1. Deploy resources
kubectl apply -f nginx-nodeport-configmaps.yaml
kubectl apply -f nginx-nodeport-deployment.yaml
kubectl apply -f nginx-nodeport-service.yaml
# 2. Wait for ready
kubectl wait --for=condition=ready pod -l app=nginx-nodeport --timeout=60s
# 3. Update content
./update-content.sh
kubectl rollout restart deployment/nginx-nodeport
---
## 🎯 What This Example Teaches
- **NodePort Services** - Standard Kubernetes service exposure
- **IPv6 Support** - Critical dual-stack configuration for Mycelium
- **Pod Isolation** - Security without hostNetwork
- **externalTrafficPolicy: Local** - Preserves source IP
- **Mycelium Integration** - IPv6 address discovery and access
---
## 📊 Architecture
```
User (with Mycelium)
↓
http://[worker-node-mycelium-ipv6]:30091
↓
kube-proxy (dual-stack enabled)
↓
Kubernetes Service (IPv4 + IPv6)
↓
Pod (container port 8080)
↓
nginx → HTML
```
**Key Points:**
- Service type: **NodePort** (not LoadBalancer)
- IP families: **Dual-stack (IPv4 + IPv6)** ⭐ Critical
- Pod network: **Isolated** (no hostNetwork)
- Traffic policy: **Local** (preserves source IP)
- Port: **30091** (NodePort)
---
## 🌐 Access URLs
**Current deployment (1 pod replica):**
- **Only accessible on the node where pod is running**
- Example: `http://[552:5984:2d97:72dc:ff0f:39ef:6ec:a48c]:30091`
**To make accessible on all nodes:**
```bash
kubectl scale deployment nginx-nodeport --replicas=3
./update-content.sh
```

### Configuration
- `nginx-nodeport-deployment.yaml` - Pod configuration
- `nginx-nodeport-service.yaml` - NodePort service (dual-stack)
- `nginx-nodeport-configmaps.yaml` - HTML content + nginx config
### Scripts
- `deploy-and-test.sh` - ⭐ **Main script** (deploy + test)
- `test-nodeport-ipv6.sh` - Testing and validation
- `update-content.sh` - Content updates
- `debug-nodeport.sh` - Diagnostics
### Documentation
- `nginx-nodeport.md` - Complete guide
- `IPV6_FIX.md` - Critical dual-stack configuration
- `TROUBLESHOOTING.md` - Common issues & solutions
- `compare-approaches.md` - Security comparison
- `FINAL_STATUS.md` - Complete implementation status
---
## ✅ Success Indicators
**When working, you'll see:**
- ✅ Service type: `NodePort`
- ✅ NodePort: `30091`
- ✅ IP families: `["IPv4","IPv6"]`
- ✅ Pod status: `Running`
- ✅ Test output: `✅ External Mycelium IPv6 connectivity is working!`
---
## 🚨 Prerequisites
1. **kubectl** installed and configured
2. **Mycelium Cloud cluster** with at least 1 worker node
3. **Mycelium installed** on your local machine (for testing)
4. **IPv6 connectivity** (Mycelium provides this)
---
## 🆘 Getting Help
**Common Issues:**
1. **"Failed to connect" error**
- Check if Mycelium is running on your local machine
- Verify IPv6 connectivity: `ping -6 [ipv6-address]`
2. **"External IPv6 connectivity test failed"**
- This is normal if you don't have Mycelium on your machine
- The service is still working from within the cluster
3. **Service only accessible on one node**
- This is CORRECT with `externalTrafficPolicy: Local` and 1 pod replica
- To make accessible on all nodes, scale to 3 replicas
**Troubleshooting:**
- Run: `./debug-nodeport.sh`
- Check logs: `kubectl logs -l app=nginx-nodeport --tail=50`
- Check service: `kubectl describe svc nginx-nodeport-service`
---
## 🔄 Next Steps
1. **Test scaling:**
```bash
kubectl scale deployment nginx-nodeport --replicas=3
```
2. **Try other nginx variants:**
- [`../nginx-mycelium/`](../nginx-mycelium/) - hostNetwork approach
- [`../nginx-static/`](../nginx-static/) - Simple static site
- LoadBalancer and Ingress variants (coming soon)
## 🎉 Success!
Once deployed and tested, you'll have a **fully functional website accessible via Mycelium IPv6** with:
- ✅ Production-ready security (pod isolation)
- ✅ Standard Kubernetes patterns
- ✅ Dual-stack IPv4/IPv6 support
- ✅ Comprehensive testing and monitoring
**Happy deploying! 🚀**
