 Specifying `--workload-profile-name "Consumption"` creates your app in an environment using the default `Consumption` workload profile, which costs the same as running in a Container Apps Consumption plan. When you first create the function app, it pulls the initial image from your registry.

+
+To enable the Functions host to connect to the default storage account using shared secrets, you must replace the `AzureWebJobsStorage` connection string setting with an equivalent setting that uses the user-assigned managed identity to connect to the storage account.
+
+1. Remove the existing `AzureWebJobsStorage` connection string setting:
+
+    ```azurecli    
+    az functionapp config appsettings delete --name `<APP_NAME>` --resource-group AzureFunctionsQuickstart-rg --setting-names AzureWebJobsStorage 
+    ```
+
+    The [az functionapp config appsettings delete](/cli/azure/functionapp/config/appsettings#az-functionapp-config-appsettings-delete) command removes this setting from your app. Replace `<APP_NAME>` with the name of your function app. 
+
+1. Add equivalent settings, with an `AzureWebJobsStorage__` prefix, that define a user-assigned managed identity connection to the default storage account:
+ 
+    ```azurecli
+    clientId=$(az identity show --name <USER_IDENTITY_NAME> --resource-group AzureFunctionsQuickstart-rg --query 'clientId' -o tsv)
+    az functionapp config appsettings set --name <APP_NAME> --resource-group AzureFunctionsQuickstart-rg --settings AzureWebJobsStorage__accountName=<STORAGE_NAME> AzureWebJobsStorage__credential=managedidentity AzureWebJobsStorage__clientId=$clientId
+    ```
   
+    In this example, replace `<APP_NAME>`, `<USER_IDENTITY_NAME>`, `<STORAGE_NAME>` with your function app name, the name of your identity, and the storage account name, respectively. 
+
 At this point, your functions are running in a Container Apps environment, with the required application settings already added. When needed, you can add other settings in your functions app in the standard way for Functions.
