+# Nextcloud on Azure Kubernetes Service (AKS)
+
+This repository contains infrastructure as code (IaC) for deploying Nextcloud on Azure Kubernetes Service (AKS) using Terraform and Kubernetes manifests.
+
+## Architecture
+
+The infrastructure includes:
+
+- **Azure Kubernetes Service (AKS)**: Container orchestration platform
+- **Azure PostgreSQL Flexible Server**: Database backend for Nextcloud
+- **Azure Storage Account**: Persistent storage for Nextcloud data using Azure Files
+- **Azure Virtual Network**: Network isolation and security
+- **Redis**: In-memory cache for improved performance
+- **Kubernetes Resources**: 
+  - Nextcloud application deployment
+  - Redis deployment for caching
+  - Persistent Volume Claims for data storage
+  - Services and Ingress for external access
+
+## Prerequisites
+
+- [Azure CLI](https://docs.microsoft.com/en-us/cli/azure/install-azure-cli) (>= 2.30)
+- [Terraform](https://www.terraform.io/downloads.html) (>= 1.0)
+- [kubectl](https://kubernetes.io/docs/tasks/tools/) (>= 1.24)
+- [kustomize](https://kustomize.io/) (>= 4.0) - optional, for Kustomize-based deployments
+- Azure subscription with appropriate permissions
+
+## Quick Start
+
+### 1. Deploy Infrastructure with Terraform
+
+```bash
+# Login to Azure
+az login
+
+# Navigate to terraform directory
+cd terraform
+
+# Copy example variables file
+cp terraform.tfvars.example terraform.tfvars
+
+# Edit terraform.tfvars with your desired configuration
+vim terraform.tfvars
+
+# Initialize Terraform
+terraform init
+
+# Review the planned changes
+terraform plan
+
+# Apply the configuration
+terraform apply
+```
+
+### 2. Configure kubectl
+
+```bash
+# Get AKS credentials
+az aks get-credentials --resource-group <resource-group-name> --name <aks-cluster-name>
+
+# Verify connection
+kubectl get nodes
+```
+
+### 3. Update Kubernetes Secrets
+
+After Terraform completes, update the secrets with actual values:
+
+```bash
+# Get Terraform outputs
+terraform output -json > outputs.json
+
+# Extract values (example using jq)
+POSTGRES_FQDN=$(terraform output -raw postgres_fqdn)
+POSTGRES_PASSWORD=$(terraform output -raw postgres_admin_password)
+STORAGE_ACCOUNT_NAME=$(terraform output -raw storage_account_name)
+STORAGE_ACCOUNT_KEY=$(terraform output -raw storage_account_key)
+
+# Update secrets file
+cd ../kubernetes/base
+# Edit secrets.yaml and replace placeholder values
+```
+
+Or use a script to generate secrets:
+
+```bash
+# Example: Create secrets from Terraform outputs
+kubectl create secret generic nextcloud-db \
+  --from-literal=db-host="$POSTGRES_FQDN" \
+  --from-literal=db-name="nextcloud" \
+  --from-literal=db-username="nextcloudadmin" \
+  --from-literal=db-password="$POSTGRES_PASSWORD" \
+  --namespace=nextcloud --dry-run=client -o yaml > secrets-db.yaml
+
+kubectl create secret generic azure-storage \
+  --from-literal=azurestorageaccountname="$STORAGE_ACCOUNT_NAME" \
+  --from-literal=azurestorageaccountkey="$STORAGE_ACCOUNT_KEY" \
+  --namespace=nextcloud --dry-run=client -o yaml > secrets-storage.yaml
+```
+
+### 4. Deploy Nextcloud to Kubernetes
+
+#### Option A: Using kubectl
+
+```bash
+cd kubernetes/base
+
+# Create namespace
+kubectl apply -f namespace.yaml
+
+# Apply all resources
+kubectl apply -f .
+```
+
+#### Option B: Using Kustomize (Recommended)
+
+For development environment:
+```bash
+cd kubernetes/overlays/dev
+kubectl apply -k .
+```
+
+For production environment:
+```bash
+cd kubernetes/overlays/prod
+kubectl apply -k .
+```
+
+### 5. Access Nextcloud
+
+```bash
+# Get the external IP address
+kubectl get service nextcloud -n nextcloud
+
+# Wait for EXTERNAL-IP to be assigned
+# Access Nextcloud at http://<EXTERNAL-IP>
+```
+
+For production with Ingress:
+1. Install an Ingress controller (e.g., NGINX Ingress Controller)
+2. Install cert-manager for TLS certificates
+3. Update the Ingress resource with your domain name
+4. Access Nextcloud at https://your-domain.com
+
+## Configuration
+
+### Terraform Variables
+
+Key variables in `terraform/variables.tf`:
+
+- `resource_group_name`: Azure resource group name
+- `location`: Azure region (e.g., westeurope, eastus)
+- `prefix`: Prefix for resource names
+- `node_count`: Initial number of AKS nodes
+- `vm_size`: VM size for AKS nodes
+- `postgres_admin_username`: PostgreSQL admin username
+- `postgres_database_name`: Database name for Nextcloud
+
+### Kubernetes Configuration
+
+Key configurations in `kubernetes/base/configmap.yaml`:
+
+- `NEXTCLOUD_TRUSTED_DOMAINS`: Domains allowed to access Nextcloud
+- `PHP_MEMORY_LIMIT`: PHP memory limit
+- `PHP_UPLOAD_LIMIT`: Maximum file upload size
+- `REDIS_HOST`: Redis hostname for caching
+
+## Scaling
+
+### Horizontal Pod Autoscaling
+
+To enable HPA for Nextcloud:
+
+```bash
+kubectl autoscale deployment nextcloud \
+  --cpu-percent=70 \
+  --min=2 \
+  --max=10 \
+  -n nextcloud
+```
+
+### AKS Node Autoscaling
+
+The AKS cluster is configured with autoscaling enabled. Adjust `min_node_count` and `max_node_count` in Terraform variables.
+
+## Monitoring
+
+Consider installing:
+
+- **Prometheus & Grafana**: For metrics and monitoring
+- **Azure Monitor**: For AKS and resource monitoring
+- **Log Analytics**: For centralized logging
+
+## Backup and Disaster Recovery
+
+1. **Database Backups**: Azure PostgreSQL Flexible Server provides automated backups
+2. **File Backups**: Use Azure Storage snapshots or backup solutions
+3. **Kubernetes Resources**: Store manifests in version control (this repository)
+
+## Security Considerations
+
+1. **Secrets Management**: 
+   - Use Azure Key Vault for production secrets
+   - Consider External Secrets Operator or Sealed Secrets
+   
+2. **Network Security**:
+   - Configure Network Security Groups (NSGs)
+   - Use Azure Private Link for PostgreSQL
+   - Enable Pod Security Standards
+
+3. **TLS/SSL**:
+   - Use cert-manager with Let's Encrypt for automatic certificate management
+   - Configure HTTPS-only access
+
+4. **Database Security**:
+   - Use strong passwords (auto-generated in Terraform)
+   - Restrict firewall rules
+   - Enable SSL connections
+
+## Troubleshooting
+
+### Check pod status
+```bash
+kubectl get pods -n nextcloud
+kubectl describe pod <pod-name> -n nextcloud
+kubectl logs <pod-name> -n nextcloud
+```
+
+### Check persistent volumes
+```bash
+kubectl get pv,pvc -n nextcloud
+```
+
+### Database connection issues
+```bash
+# Test from a debug pod
+kubectl run -it --rm debug --image=postgres:14 --restart=Never -- psql -h <postgres-fqdn> -U nextcloudadmin -d nextcloud
+```
+
+## Cleanup
+
+To destroy all resources:
+
+```bash
+# Delete Kubernetes resources
+kubectl delete namespace nextcloud
+
+# Destroy Terraform infrastructure
+cd terraform
+terraform destroy
+```

+# Architecture Overview
+
+This document describes the architecture of the Nextcloud deployment on Azure Kubernetes Service.
+
+## Components
+
+### Azure Infrastructure
+
+1. **Resource Group**: Container for all resources
+2. **Virtual Network**: Isolated network (10.0.0.0/16)
+   - AKS Subnet (10.0.1.0/24)
+   - PostgreSQL Subnet (10.0.2.0/24)
+3. **AKS Cluster**: Kubernetes orchestration
+   - Autoscaling: 1-5 nodes
+   - VM Size: Standard_D2s_v3
+4. **PostgreSQL Flexible Server**: Database backend
+   - Version: 14
+   - Storage: 32 GB
+5. **Storage Account**: Azure Files for persistent data
+   - 100 GB file share
+

+# Deployment Guide
+
+This guide provides step-by-step instructions for deploying Nextcloud on Azure Kubernetes Service.
+
+## Prerequisites
+
+Before starting, ensure you have:
+
+1. **Azure Account** with an active subscription
+2. **Azure CLI** installed and logged in (`az login`)
+3. **Terraform** (>= 1.0) installed
+4. **kubectl** (>= 1.24) installed
+5. Appropriate Azure permissions to create resources
+
+## Automated Deployment
+
+The quickest way to deploy is using the provided script:
+
+```bash
+cd scripts
+./deploy.sh
+```
+
+This script will:
+- Deploy the Terraform infrastructure
+- Configure kubectl
+- Create all necessary secrets
+- Deploy Nextcloud to Kubernetes
+- Wait for the service to be ready
+- Display the access URL
+
+## Manual Deployment
+
+For more control over the deployment process, follow these steps:
+
+### Step 1: Configure Terraform
+
+```bash
+cd terraform
+cp terraform.tfvars.example terraform.tfvars
+# Edit terraform.tfvars with your settings
+```
+
+### Step 2: Deploy Infrastructure
+
+```bash
+terraform init
+terraform plan
+terraform apply
+```
+
+### Step 3: Configure Kubernetes
+
+```bash
+az aks get-credentials --resource-group <rg-name> --name <aks-name>
+kubectl get nodes
+```
+
+### Step 4: Create Secrets
+
+```bash
+kubectl create secret generic nextcloud-db --namespace=nextcloud \
+  --from-literal=db-host="$(terraform output -raw postgres_fqdn)" \
+  --from-literal=db-name="nextcloud" \
+  --from-literal=db-username="nextcloudadmin" \
+  --from-literal=db-password="$(terraform output -raw postgres_admin_password)"
+```
+
+### Step 5: Deploy Application
+
+```bash
+cd ../kubernetes/overlays/prod
+kubectl apply -k .
+```
+
+## Troubleshooting
+
+Check pod logs:
+```bash
+kubectl logs -f deployment/nextcloud -n nextcloud
+```
+
+Check resource status:
+```bash
+kubectl get all -n nextcloud
+```
+
+## Cleanup
+
+```bash
+cd scripts
+./cleanup.sh
+```

 ## Troubleshooting
 
+### Terraform deployment errors
+
+#### LocationIsOfferRestricted error for PostgreSQL
+If you encounter an error like:
+```
+Error: creating Flexible Server ... Status: "LocationIsOfferRestricted"
+Message: "Subscriptions are restricted from provisioning in location 'westeurope'..."
+```
+
+**Solution**: Your Azure subscription has restrictions on PostgreSQL Flexible Server in that region. 
+
+1. Change the `location` variable in `terraform/terraform.tfvars` to a different region:
+   ```hcl
+   location = "eastus"  # or try: westus2, northeurope, uksouth
+   ```
+
+2. Run `terraform destroy` to clean up any partial deployment, then `terraform apply` again
+
+3. Alternatively, request a quota increase following the link in the error message
+
+**Note**: The default region has been changed to `eastus` which has better availability.
+

 ### Terraform deployment errors
 
-#### LocationIsOfferRestricted error for PostgreSQL
-If you encounter an error like:
-```
-Error: creating Flexible Server ... Status: "LocationIsOfferRestricted"
-Message: "Subscriptions are restricted from provisioning in location 'westeurope'..."
-```
-
-**Solution**: Your Azure subscription has restrictions on PostgreSQL Flexible Server in that region. 
-
-1. Change the `location` variable in `terraform/terraform.tfvars` to a different region:
-   ```hcl
-   location = "eastus"  # or try: westus2, northeurope, uksouth
-   ```
-
-2. Run `terraform destroy` to clean up any partial deployment, then `terraform apply` again
-
-3. Alternatively, request a quota increase following the link in the error message
-
-**Note**: The default region has been changed to `eastus` which has better availability.
+Note: This deployment now uses MariaDB which has better availability across Azure regions including westeurope.

+## Troubleshooting
+
+### Nextcloud Pods Crashing
+
+If Nextcloud pods are in CrashLoopBackOff state:
+
+1. **Check if MySQL is running:**
+```bash
+kubectl get pods -n nextcloud -l app=mysql
+kubectl get statefulset -n nextcloud
+```
+
+2. **If MySQL pod doesn't exist, deploy it:**
+```bash
+kubectl apply -f kubernetes/base/mysql-statefulset.yaml
+```
+
+3. **Wait for MySQL to be ready:**
+```bash
+kubectl wait --for=condition=ready pod -l app=mysql -n nextcloud --timeout=300s
+```
+
+4. **Check MySQL logs:**
+```bash
+kubectl logs -n nextcloud -l app=mysql
+```
+
+5. **Restart Nextcloud after MySQL is ready:**
+```bash
+kubectl rollout restart deployment/nextcloud -n nextcloud
+```

+1. **Verify secrets are correct:**
+```bash
+kubectl get secret nextcloud-db -n nextcloud -o yaml
+```
+
+2. **Test database connectivity from a debug pod:**
+```bash
+kubectl run -it --rm debug --image=mysql:8.0 --restart=Never -n nextcloud -- mysql -h mysql -u nextcloud -p
+```
+
+3. **Check MySQL service:**
+```bash
+kubectl get svc mysql -n nextcloud
+```
+
+### MySQL StatefulSet Issues
+
+If MySQL pod won't start:
+
+1. **Check persistent volume claim:**
+```bash
+kubectl get pvc -n nextcloud
+```
+
+2. **Check MySQL logs:**
+```bash
+kubectl logs -n nextcloud mysql-0
+```
+
+3. **Describe the MySQL pod:**
+```bash
+kubectl describe pod mysql-0 -n nextcloud
+```
+
+### Pods Stuck in Pending State
+
+If pods remain in Pending state:
+
+1. **Check node availability:**
+```bash
+kubectl get nodes
+```
+
+2. **Describe the pending pod:**
+```bash
+kubectl describe pod <pod-name> -n nextcloud
+```
+
+3. **Check for resource constraints or PVC binding issues**
+
+### Re-deployment
+
+If you need to completely redeploy:
+
+1. **Delete all Kubernetes resources:**
+```bash
+kubectl delete namespace nextcloud
+```
+
+2. **Recreate namespace:**
+```bash
+kubectl create namespace nextcloud
+```
+
+3. **Run deployment script again:**
+```bash
+cd scripts
+./deploy.sh
+```

-## Troubleshooting
+## Scaling Nextcloud
+
+**Important:** The deployment starts with **1 replica** to avoid concurrent database initialization conflicts.
 
-Note: This deployment now uses MySQL which has better availability in westeurope and other regions.
+### After Initial Deployment
 
-### Pod Issues
+Once Nextcloud is fully initialized and running (all pods show READY 1/1), you can scale to multiple replicas:
 
-Check pod logs:
 ```bash
-kubectl logs -f deployment/nextcloud -n nextcloud
+# Scale to 2 replicas (default for base)
+kubectl scale deployment nextcloud -n nextcloud --replicas=2
+
+# Or scale to 3 replicas (recommended for prod)
+kubectl scale deployment nextcloud -n nextcloud --replicas=3
 ```
 
-Check resource status:
+### Why Start with 1 Replica?
+
+Nextcloud's initialization process:
+- Creates database schema and tables on first run
+- Uses file locking to prevent concurrent initialization
+- Multiple pods starting simultaneously causes "flock: Permission denied" errors
+- After initialization, Nextcloud supports multiple replicas without issues
+
+### Verifying Initialization
+
+Check if Nextcloud has completed initialization:
+
 ```bash
-kubectl get all -n nextcloud
+# Check pod status - should show READY 1/1
+kubectl get pods -n nextcloud -l app=nextcloud
+
+# Check logs - should show "Nextcloud is already installed"
+kubectl logs -n nextcloud -l app=nextcloud --tail=20
+
+# Once you see "Nextcloud is already installed", it's safe to scale up
+kubectl scale deployment nextcloud -n nextcloud --replicas=2
 ```
 
 ## Cleanup
 
+To remove all deployed resources:
+
 ```bash
 cd scripts
 ./cleanup.sh
 ```
 
+Or manually:
+
+```bash
+# Delete Kubernetes resources
+kubectl delete namespace nextcloud
+
+# Delete Azure infrastructure
+cd terraform
+terraform destroy
+```
+
 ## Troubleshooting
 
+Note: This deployment uses containerized MySQL which works in all Azure regions without subscription restrictions.
+
+### Common Issues
+
+#### Concurrent Initialization Conflicts
+
+If you see errors like "flock: Permission denied" or "Another process is initializing Nextcloud":
+
+**Cause:** Multiple Nextcloud pods trying to initialize the database simultaneously.
+
+**Solution:**
+1. **Delete all Nextcloud pods to stop conflicting initialization:**
+```bash
+kubectl delete pods -n nextcloud -l app=nextcloud
+```
+
+2. **Ensure only 1 replica is configured during first deployment:**
+```bash
+kubectl scale deployment nextcloud -n nextcloud --replicas=1
+```
+
+3. **Wait for initialization to complete** (5-10 minutes):
+```bash
+kubectl logs -f -n nextcloud -l app=nextcloud
+# Wait until you see "Nextcloud is already installed"
+```
+
+4. **Once initialized, scale to desired replicas:**
+```bash
+kubectl scale deployment nextcloud -n nextcloud --replicas=2
+```
+
+**Prevention:** The base deployment now starts with 1 replica by default to avoid this issue.

 This guide provides step-by-step instructions for deploying Nextcloud on Azure Kubernetes Service.
 
+## Storage Architecture
+
+This deployment uses an **optimized split storage approach** for fast initialization and reliable multi-pod operations:
+
+### What Gets Mounted Where
+
+1. **Application Code** (`/var/www/html/*` except data and config):
+   - **Remains in container** filesystem
+   - **Why**: Fast initialization (no rsync overhead)
+   - Includes: PHP files, apps, themes, assets
+
+2. **User Data** (`/var/www/html/data`):
+   - **Mounted from Azure Files** (ReadWriteMany)
+   - **Why**: User-uploaded files need to be shared across all pods
+   - Size: 100GB
+
+3. **Configuration** (`/var/www/html/config`):
+   - **Mounted from Azure Files** (ReadWriteMany)
+   - **Why**: Config.php and settings must be consistent across pods
+   - Size: 1GB
+
+### Why Not Mount Entire /var/www/html?
+
+Mounting the entire Nextcloud directory on Azure Files causes:
+- **Extremely slow initialization** (15-30 minutes for rsync operations)
+- Connection timeouts and pod restarts
+- Startup probe failures
+
+With split storage:
+- ✅ **Fast initialization** (2-5 minutes instead of 30+ minutes)
+- ✅ **Reliable startup** (no timeouts)
+- ✅ **Multi-pod support** (data and config shared via Azure Files)
+- ✅ **Best practice** Nextcloud architecture
+

+### Updating Trusted Domains
+
+The deployment automatically configures trusted domains using an init container that runs before each pod starts. The init container uses the `occ` command to update the config.php file.
+
+**Configured trusted domains:**
+- `*.azurewebsites.net` (Azure web apps)
+- `*.westeurope.cloudapp.azure.com` (Azure public IP DNS names)
+- `nextcloud.example.com` (your custom domain placeholder)
+
+**To add additional trusted domains:**
+
+1. Edit the init container in `kubernetes/base/nextcloud-deployment.yaml`:
+```yaml
+su -s /bin/sh www-data -c "php /var/www/html/occ config:system:set trusted_domains 4 --value='your.domain.com'"
+```
+
+2. Apply the changes:
+```bash
+kubectl apply -f kubernetes/base/nextcloud-deployment.yaml
+kubectl delete pods -n nextcloud -l app=nextcloud
+```
+
+**To manually update trusted domains in a running pod:**
+```bash
+POD_NAME=$(kubectl get pods -n nextcloud -l app=nextcloud -o jsonpath='{.items[0].metadata.name}')
+kubectl exec -n nextcloud $POD_NAME -- su -s /bin/sh www-data -c "php occ config:system:set trusted_domains 4 --value='your.domain.com'"

+### Trusted Domains Configuration
+
+The deployment includes an init container that automatically configures trusted domains:
+- **During initial installation**: Uses `NEXTCLOUD_TRUSTED_DOMAINS` environment variable
+- **For existing installations**: Init container uses `occ` command to update config.php
+- Configured domains: `*.azurewebsites.net`, `*.westeurope.cloudapp.azure.com`, `nextcloud.example.com`
+- Init container only runs when config.php exists (after first installation completes)
+- Allows access via Azure public IP DNS names and custom domains
