+# Azure Bicep - @onlyIfNotExists Decorator
+
+## Introduction
+
+The `@onlyIfNotExists()` decorator in Azure Bicep enables **conditional resource deployment** based on whether a resource with the specified name already exists. When applied to a resource declaration, Azure Resource Manager will only create the resource if one with that name doesn't already exist in the target scope.
+
+It's particularly valuable for deploying resources that should only be created once, such as Key Vault secrets, where you want to avoid overwriting existing values or encountering "resource already exists" errors.
+
+> [!NOTE]  
+> The decorator checks only the resource **name** - it does not compare properties or configurations. If a resource with the same name exists, deployment is skipped entirely for that resource, regardless of whether its properties match the template definition.
+
+Learn more about the `@onlyIfNotExists()` decorator in the [official Microsoft Learn documentation](https://learn.microsoft.com/azure/azure-resource-manager/bicep/resource-declaration?WT.mc_id=MVP_319025#onlyifnotexists-decorator).
+
+## ✅ Benefits of Using @onlyIfNotExists
+
+✅ **Prevents Overwriting Critical Data**: Protects existing resources (like secrets with sensitive values) from being accidentally overwritten during redeployment.
+
+✅ **Idempotent Deployments**: Enables truly idempotent templates where multiple executions won't fail or cause unintended changes if resources already exist.
+
+✅ **Simplified Secret Management**: Perfect for one-time secret deployments where you want to set an initial value but never modify it through automation afterward.
+
+✅ **Reduces Deployment Errors**: Eliminates "resource already exists" conflicts in scenarios where you're uncertain whether a resource has been previously deployed.
+
+## ⚗️ Example: Key Vault Secret with @onlyIfNotExists
+
+This example demonstrates deploying an Azure Key Vault and a secret using the `@onlyIfNotExists()` decorator. The Key Vault will always be deployed (or updated), but the secret will **only be created if it doesn't already exist**.
+
+### Bicep Code Snippet
+
+```bicep
+@secure()
+param kvSecretValue string
+
+// Deploy secret to the Key Vault using @onlyIfNotExists decorator
+@onlyIfNotExists()
+resource kvSecret 'Microsoft.KeyVault/vaults/secrets@2023-07-01' = {
+  name: '${keyVault.outputs.name}/mySecret'
+  properties: {
+    value: kvSecretValue
+  }
+}
+```
+
+### How It Works
+
+1. **First Deployment**: The secret `mySecret` doesn't exist, so it's created with the value you pass at deployment time
+2. **Subsequent Deployments**: The secret already exists with the same name, so deployment is skipped entirely - the existing value is preserved
+3. **Name-Based Check**: Only the secret name is checked; if a secret named `mySecret` exists, it won't be recreated regardless of its current value (check the secret version after two deployment runs to verify functionality.)
+
+### Full Template
+
+The complete `main.bicep` file includes:
+
+- Azure Key Vault deployment using the Azure Verified Modules (AVM) pattern
+- A secret resource with the `@onlyIfNotExists()` decorator
+- Metadata for resource documentation
+- Outputs for the Key Vault name, URI, and secret name
+
+### Scope Limitations
+
+The existence check is performed within the deployment scope (subscription, resource group, etc.). A resource in a different scope with the same name won't prevent creation.
+
+## 🚀 Deployment
+
+### Prerequisites
+
+- Azure subscription
+- Bicep CLI 0.38.0 or later
+
+### Deploy with Azure CLI
+
+```bash
+az group create --name rg-onlyIfNotExists-example --location uksouth
+
+az deployment group create \
+  --resource-group rg-onlyIfNotExists-example \
+  --template-file main.bicep \
+  --parameters kvSecretValue="<your-secret-value>"
+```
+
+### Deploy with Azure PowerShell
+
+```powershell
+New-AzResourceGroup -Name rg-onlyIfNotExists-example -Location uksouth
+
+New-AzResourceGroupDeployment `
+  -ResourceGroupName rg-onlyIfNotExists-example `
+  -TemplateFile main.bicep `
+  -kvSecretValue '<your-secret-value>'
+```
