+# ArgoCD Configuration Documentation
+
+## Overview
+This directory contains the ArgoCD application manifests for deploying the VorgabenUI application and its dependencies to Kubernetes.
+
+## Files
+
+### Application Manifests
+
+#### `001_pvc.yaml`
+- **Purpose**: PersistentVolumeClaim for Django application data
+- **Storage**: 2Gi storage with ReadWriteMany access mode
+- **Storage Class**: Uses NFS storage class for shared storage across multiple pods
+- **Namespace**: vorgabenui
+
+#### `deployment.yaml`
+- **Purpose**: Main application deployment configuration
+- **Contains**: Django application container, environment variables, resource limits
+- **Replicas**: Configurable replica count for high availability
+
+#### `ingress.yaml`
+- **Purpose**: External access configuration
+- **Host**: Configurable hostname for the application
+- **TLS**: SSL/TLS termination configuration
+- **Backend**: Routes traffic to the Django application service
+
+#### `nfs-pv.yaml`
+- **Purpose**: PersistentVolume definition for NFS storage
+- **Server**: 192.168.17.199
+- **Path**: /mnt/user/vorgabenui
+- **Access**: ReadWriteMany for multi-pod access
+- **Reclaim Policy**: Retain (data preserved after PVC deletion)
+
+#### `nfs-storageclass.yaml`
+- **Purpose**: StorageClass definition for NFS volumes
+- **Provisioner**: kubernetes.io/no-provisioner (static provisioning)
+- **Volume Expansion**: Enabled for growing storage capacity
+- **Binding Mode**: Immediate (binds PV to PVC as soon as possible)
+
+#### `diagrammer.yaml`
+- **Purpose**: Deployment configuration for the diagram generation service
+- **Function**: Handles diagram creation and caching for the application
+
+## NFS Storage Configuration
+
+### Prerequisites
+1. NFS server must be running at 192.168.17.199
+2. The directory `/mnt/user/vorgabenui` must exist and be exported
+3. Kubernetes nodes must have NFS client utilities installed
+4. For MicroK8s: `microk8s enable nfs`
+
+## MicroK8s Addons Required
+
+### Required Addons
+Enable the following MicroK8s addons before deployment:
+
+```bash
+# Enable storage and NFS support
+sudo microk8s enable storage
+sudo microk8s enable nfs
+
+# Enable ingress for external access
+sudo microk8s enable ingress
+
+# Enable DNS for service discovery
+sudo microk8s enable dns
+
+# Optional: Enable metrics for monitoring
+sudo microk8s enable metrics-server
+```
+
+### Addon Descriptions
+
+#### `storage`
+- **Purpose**: Provides default storage class for persistent volumes
+- **Required for**: Basic PVC functionality
+- **Note**: Works alongside our custom NFS storage class
+
+#### `nfs`
+- **Purpose**: Installs NFS client utilities on all MicroK8s nodes
+- **Required for**: Mounting NFS volumes in pods
+- **Components**: Installs `nfs-common` package with mount helpers
+
+#### `ingress`
+- **Purpose**: Provides Ingress controller for external HTTP/HTTPS access
+- **Required for**: `ingress.yaml` to function properly
+- **Implementation**: Uses NGINX Ingress Controller
+
+#### `dns`
+- **Purpose**: Provides DNS service for service discovery within cluster
+- **Required for**: Inter-service communication
+- **Note**: Usually enabled by default in MicroK8s
+
+#### `metrics-server` (Optional)
+- **Purpose**: Enables resource usage monitoring
+- **Required for**: `kubectl top` commands and HPA (Horizontal Pod Autoscaling)
+- **Recommended for**: Production monitoring
+
+### Addon Verification
+After enabling addons, verify they are running:
+
+```bash
+# Check addon status
+microk8s status
+
+# Check pods in kube-system namespace
+microk8s kubectl get pods -n kube-system
+
+# Check storage classes
+microk8s kubectl get storageclass
+
+# Check ingress controller
+microk8s kubectl get pods -n ingress
+```
+
+### Troubleshooting Addons
+
+#### NFS Addon Issues
+```bash
+# Check if NFS utilities are installed
+which mount.nfs
+
+# Manually install if addon fails
+sudo apt update && sudo apt install nfs-common
+
+# Restart MicroK8s after manual installation
+sudo microk8s restart
+```
+
+#### Ingress Issues
+```bash
+# Check ingress controller pods
+microk8s kubectl get pods -n ingress
+
+# Check ingress services
+microk8s kubectl get svc -n ingress
+
+# Test ingress connectivity
+curl -k https://your-domain.com
+```
+
+#### Storage Issues
+```bash
+# List available storage classes
+microk8s kubectl get storageclass
+
+# Check default storage class
+microk8s kubectl get storageclass -o yaml
+```
+
+### Storage Architecture
+- **Storage Class**: `nfs` - Static provisioning for NFS shares
+- **Persistent Volume**: Pre-provisioned PV pointing to NFS server
+- **Persistent Volume Claim**: Claims the NFS storage for application use
+- **Access Mode**: ReadWriteMany allows multiple pods to access the same data
+
+### NFS Server Setup
+On the NFS server (192.168.17.199), ensure the following:
+
+```bash
+# Create the shared directory
+sudo mkdir -p /mnt/user/vorgabenui
+sudo chmod 755 /mnt/user/vorgabenui
+
+# Add to /etc/exports
+echo "/mnt/user/vorgabenui *(rw,sync,no_subtree_check,no_root_squash)" | sudo tee -a /etc/exports
+
+# Export the directory
+sudo exportfs -a
+sudo systemctl restart nfs-kernel-server
+```
+
+## Deployment Order
+
+1. **StorageClass** (`nfs-storageclass.yaml`) - Defines NFS storage class
+2. **PersistentVolume** (`nfs-pv.yaml`) - Creates the NFS volume
+3. **PersistentVolumeClaim** (`001_pvc.yaml`) - Claims storage for application
+4. **Application Deployments** (`deployment.yaml`, `diagrammer.yaml`) - Deploy application services
+5. **Ingress** (`ingress.yaml`) - Configure external access
+
+## Configuration Notes
+
+### Namespace
+All resources are deployed to the `vorgabenui` namespace.
+
+### Storage Sizing
+- Current allocation: 2Gi
+- Volume expansion is enabled through the StorageClass
+- Monitor usage and adjust PVC size as needed
+
+### Access Control
+- NFS export uses `no_root_squash` for container root access
+- Ensure proper network security between Kubernetes nodes and NFS server
+- Consider implementing network policies for additional security
+
+## Troubleshooting
+
+### Common Issues
+
+#### Mount Failures
+- **Error**: "bad option; for several filesystems you might need a /sbin/mount.<type> helper program"
+- **Solution**: Install NFS client utilities or enable NFS addon in MicroK8s
+
+#### Permission Issues
+- **Error**: Permission denied when accessing mounted volume
+- **Solution**: Check NFS export permissions and ensure `no_root_squash` is set
+
+#### Network Connectivity
+- **Error**: Connection timeout to NFS server
+- **Solution**: Verify network connectivity and firewall rules between nodes and NFS server
+
+### Debug Commands
+```bash
+# Check PVC status
+kubectl get pvc -n vorgabenui
+
+# Check PV status
+kubectl get pv
+
+# Describe PVC for detailed information
+kubectl describe pvc django-data-pvc -n vorgabenui
+
+# Check pod mount status
+kubectl describe pod <pod-name> -n vorgabenui
+```
+
+## Maintenance
+
+### Backup Strategy
+- The NFS server should have regular backups of `/mnt/user/vorgabenui`
+- Consider snapshot capabilities if using enterprise NFS solutions
+
+### Monitoring
+- Monitor NFS server performance and connectivity
+- Track storage usage and plan capacity upgrades
+- Monitor pod restarts related to storage issues
+
+### Updates
+- When updating storage configuration, update PV first, then PVC
+- Test changes in non-production environment first
+- Ensure backward compatibility when modifying NFS exports
