+
+## ๐ Access Methods
+
+### Method 1: Port-Forward (Recommended for Mycelium Cloud)
+
+**Option 1: Simple (Recommended)**
+```bash
+# Keep terminal open, forward WordPress port
+kubectl port-forward service/wordpress-service 8080:80
+
+# Access WordPress setup
+curl http://localhost:8080
+```
+
+**Option 2: Background**
+```bash
+# Start in background
+nohup kubectl port-forward service/wordpress-service 8080:80 > wordpress-access.log 2>&1 &
+
+# Access WordPress
+curl http://localhost:8080
+```
+
+### Method 2: Direct Pod Access (Inside Cluster)
+
+**WordPress CLI Access:**
+```bash
+# Execute WordPress commands
+kubectl exec -it $(kubectl get pod -l app=wordpress -o jsonpath='{.items[0].metadata.name}') -c wordpress -- wp --allow-root --info
+
+# Access WordPress shell
+kubectl exec -it $(kubectl get pod -l app=wordpress -o jsonpath='{.items[0].metadata.name}') -c wordpress -- /bin/bash
+```
+
+**Database Access:**
+```bash
+# Access MariaDB
+kubectl exec -it $(kubectl get pod -l app=wordpress -o jsonpath='{.items[0].metadata.name}') -c mariadb -- mysql -u root -p"mycelium-root-password-2025"
+
+# WordPress database access
+kubectl exec -it $(kubectl get pod -l app=wordpress -o jsonpath='{.items[0].metadata.name}') -c mariadb -- mysql -u wordpress -p"mycelium-secure-password-2025" wordpress
+```
+
+### Method 3: LoadBalancer IP Access (If Available)
+
+```bash
+# Get LoadBalancer IP (may be internal on Mycelium Cloud)
+kubectl get svc wordpress-service
+
+# Access WordPress (if external IP available)
+curl http://:80
+```
+
+## ๐ WordPress Management
+
+### Initial Setup
+1. **Visit WordPress Setup**: http://localhost:8080
+2. **Choose Language**: Select your preferred language
+3. **Site Configuration**:
+ - Site Title: "Mycelium Cloud WordPress"
+ - Username: "admin" (or your choice)
+ - Password: Generate secure password
+ - Email: Your email address
+4. **Complete Setup**: WordPress will create database tables and configure
+
+### WordPress CLI Management
+```bash
+# Install WordPress CLI in pod
+kubectl exec -it $(kubectl get pod -l app=wordpress -o jsonpath='{.items[0].metadata.name}') -c wordpress -- \
+ curl -O https://raw.githubusercontent.com/wp-cli/wp-cli/master/phar/wp-cli.phar && \
+ chmod +x wp-cli.phar
+
+# Basic WordPress operations
+kubectl exec -it $(kubectl get pod -l app=wordpress -o jsonpath='{.items[0].metadata.name}') -c wordpress -- \
+ ./wp-cli.phar --allow-root --info
+
+# List plugins
+kubectl exec -it $(kubectl get pod -l app=wordpress -o jsonpath='{.items[0].metadata.name}') -c wordpress -- \
+ ./wp-cli.phar --allow-root plugin list
+
+# Install theme
+kubectl exec -it $(kubectl get pod -l app=wordpress -o jsonpath='{.items[0].metadata.name}') -c wordpress -- \
+ ./wp-cli.phar --allow-root theme install twentytwentyfour
+```
+
+### Database Operations
+```bash
+# Access WordPress database
+kubectl exec -it $(kubectl get pod -l app=wordpress -o jsonpath='{.items[0].metadata.name}') -c mariadb -- \
+ mysql -u wordpress -p"mycelium-secure-password-2025" wordpress -e "SHOW TABLES;"
+
+# Check WordPress users
+kubectl exec -it $(kubectl get pod -l app=wordpress -o jsonpath='{.items[0].metadata.name}') -c mariadb -- \
+ mysql -u wordpress -p"mycelium-secure-password-2025" wordpress -e "SELECT * FROM wp_users;"
+
+# Database backup
+kubectl exec -it $(kubectl get pod -l app=wordpress -o jsonpath='{.items[0].metadata.name}') -c mariadb -- \
+ mysqldump -u wordpress -p"mycelium-secure-password-2025" wordpress > wordpress-backup.sql
+```
+
+## ๐ Troubleshooting
+
+### Check Deployment Status
+```bash
+# Check pods status (should show 2/2 Ready)
+kubectl get pods -l app=wordpress
+
+# Check service details
+kubectl get svc wordpress-service
+
+# Check PersistentVolumeClaims
+kubectl get pvc wordpress-database-pvc wordpress-content-pvc
+
+# Check ConfigMaps
+kubectl get configmap wordpress-config wordpress-mariadb-config
+```
+
+### Common Issues
+
+#### Pod Not Starting
+```bash
+# Check pod status and events
+kubectl describe pod -l app=wordpress
+
+# Check container logs
+kubectl logs -l app=wordpress
+kubectl logs -l app=wordpress -c wordpress
+kubectl logs -l app=wordpress -c mariadb --previous
+```
+
+#### Database Connection Issues
+```bash
+# Check MariaDB connectivity from WordPress container
+kubectl exec -it $(kubectl get pod -l app=wordpress -o jsonpath='{.items[0].metadata.name}') -c wordpress -- \
+ mysqladmin ping -h localhost -u wordpress -p"mycelium-secure-password-2025"
+
+# Test database access
+kubectl exec -it $(kubectl get pod -l app=wordpress -o jsonpath='{.items[0].metadata.name}') -c mariadb -- \
+ mysql -u root -p"mycelium-root-password-2025" -e "SHOW DATABASES;"
+```
+
+#### WordPress Installation Issues
+```bash
+# Check WordPress configuration
+kubectl exec -it $(kubectl get pod -l app=wordpress -o jsonpath='{.items[0].metadata.name}') -c wordpress -- \
+ cat /var/www/html/wp-config.php
+
+# Check WordPress directory permissions
+kubectl exec -it $(kubectl get pod -l app=wordpress -o jsonpath='{.items[0].metadata.name}') -c wordpress -- \
+ ls -la /var/www/html/
+
+# Test WordPress initialization
+kubectl exec -it $(kubectl get pod -l app=wordpress -o jsonpath='{.items[0].metadata.name}') -c wordpress -- \
+ /init-wordpress.sh
+```
+
+#### Persistent Volume Issues
+```bash
+# Check PVC status
+kubectl describe pvc wordpress-database-pvc
+kubectl describe pvc wordpress-content-pvc
+
+# Check volume mount in containers
+kubectl exec -it $(kubectl get pod -l app=wordpress -o jsonpath='{.items[0].metadata.name}') -c mariadb -- \
+ ls -la /var/lib/mysql/
+
+kubectl exec -it $(kubectl get pod -l app=wordpress -o jsonpath='{.items[0].metadata.name}') -c wordpress -- \
+ ls -la /var/www/html/
+```
+
+#### Port Conflicts
+```bash
+# Check if port 8080 is in use
+lsof -i :8080
+
+# Check port 80 conflicts
+kubectl exec -it $(kubectl get pod -l app=wordpress -o jsonpath='{.items[0].metadata.name}') -c wordpress -- \
+ netstat -tlnp | grep :80
+```
+
+## ๐ ๏ธ Common Operations
+
+### Scaling (Note: WordPress scaling is complex)
+```bash
+# Note: WordPress is typically single-instance due to file-based sessions
+# For horizontal scaling, you'd need shared storage and session management
+kubectl scale deployment wordpress --replicas=1
+
+# Check distribution
+kubectl get pods -o wide
+```
+
+### Updates
+```bash
+# Update WordPress image
+kubectl set image deployment/wordpress wordpress=wordpress:6.5-php8.2-apache
+
+# Update MariaDB image
+kubectl set image deployment/wordpress mariadb=mariadb:11.0
+
+# Restart deployment
+kubectl rollout restart deployment/wordpress
+
+# Check rollout status
+kubectl rollout status deployment/wordpress
+```
+
+### Data Management
+```bash
+# Access WordPress database
+kubectl exec -it $(kubectl get pod -l app=wordpress -o jsonpath='{.items[0].metadata.name}') -c mariadb -- mysql -u wordpress -p"mycelium-secure-password-2025" wordpress
+
+# Common database operations inside pod:
+# SHOW TABLES;
+# DESCRIBE wp_posts;
+# SELECT * FROM wp_options;
+# FLUSH PRIVILEGES;
+```
+
+### Monitoring
+```bash
+# View logs from both containers
+kubectl logs -f deployment/wordpress
+kubectl logs -f deployment/wordpress -c wordpress
+kubectl logs -f deployment/wordpress -c mariadb
+
+# Monitor resource usage
+kubectl top pod -l app=wordpress
+
+# Check database status
+kubectl exec -it $(kubectl get pod -l app=wordpress -o jsonpath='{.items[0].metadata.name}') -c mariadb -- \
+ mysqladmin -u root -p"mycelium-root-password-2025" status
+```
+
+## ๐งน Cleanup
+
+When you're done testing:
+
+```bash
+# Delete the application and service
+kubectl delete -f wordpress-deployment.yaml -f wordpress-service.yaml -f wordpress-configmap.yaml
+
+# Wait for cleanup
+kubectl wait --for=delete pod -l app=wordpress --timeout=60s
+
+# Kill any port-forwards
+lsof -ti:8080 | xargs kill -9 2>/dev/null || true
+
+# Verify cleanup
+kubectl get all -l app=wordpress
+kubectl get pvc wordpress-database-pvc wordpress-content-pvc 2>/dev/null || echo "PVCs deleted"
+kubectl get configmap wordpress-config wordpress-mariadb-config 2>/dev/null || echo "ConfigMaps deleted"
+```
+
+## ๐ฏ What This Demonstrates
+
+This example shows:
+- **Advanced Kubernetes patterns** - multi-container pods, init containers, persistent volumes
+- **Production WordPress deployment** - proper configuration, security, performance
+- **Database integration** - MariaDB setup, persistent storage, initialization
+- **Mycelium Cloud networking** - LoadBalancer services, port-forwarding, dual-stack
+- **Container orchestration** - resource management, health monitoring, init containers
+- **Development workflows** - testing, debugging, configuration management
+- **Production patterns** - worker node preferences, scaling considerations
+
+## ๐ Next Steps
+
+Once you understand this example, try:
+
+1. **WordPress Clustering** - Multiple WordPress instances with shared database
+2. **Advanced Scaling** - Load balancing, shared storage, session management
+3. **WordPress Multisite** - Multiple WordPress sites on one deployment
+4. **Plugin Management** - Automated plugin/theme deployment
+5. **Backup Strategies** - Database and file backups
+6. **Security Hardening** - SSL/TLS, security headers, access controls
+7. **Performance Optimization** - Caching, CDN integration
+8. **Monitoring** - WordPress performance and database monitoring
+
+## ๐ More Examples
+
+Other available examples:
+- **hello-world/** - Basic web application deployment
+- **nginx-static/** - Static website hosting
+- **python-flask/** - Python API server
+- **redis-cache/** - Data caching services
+- **nginx-nodeport/** - NodePort scaling with workers
+
+## ๐ก Pro Tips
+
+1. **Multi-Container Access**: Use `-c container-name` to access specific containers
+2. **Init Containers**: Check init container logs for setup issues
+3. **WordPress CLI**: Great for automated WordPress management
+4. **Database Backup**: Always backup before major changes
+5. **Resource Monitoring**: Watch memory usage, especially during WordPress operations
+6. **Network Testing**: Use `kubectl exec` for internal cluster testing
+7. **Background Services**: Use `&` to run multiple port-forwards
+8. **Persistent Storage**: Verify PVC mounting for data persistence
+
