Azure App Configuration supports the following methods to read and manage your configuration during deployment:

Manage Azure App Configuration resources in deployment

Azure Resource Manager Authorization

You must have Azure Resource Manager permissions to manage Azure App Configuration resources. Azure role-based access control (Azure RBAC) roles that provide these permissions include the Microsoft.AppConfiguration/configurationStores/write or Microsoft.AppConfiguration/configurationStores/* action. Built-in roles with this action include:

  • Owner
  • Contributor

Manage Azure App Configuration data in deployment

Azure App Configuration data, such as key-values and snapshots, can be managed in deployment. When managing App Configuration data using this method, it's recommended to set your configuration store's Azure Resource Manager authentication mode to Pass-through. This authentication mode ensures that data access requires a combination of data plane and Azure Resource Manager management roles and ensuring that data access can be properly attributed to the deployment caller for auditing purpose.

Azure Resource Manager authentication mode

To configure the Azure Resource Manager authentication mode of an Azure App Configuration resource in the Azure portal, follow these steps:

  1. Navigate to your Azure App Configuration resource in the Azure portal

  2. Locate the Access settings setting under Settings

  3. Select the recommended Pass-through authentication mode under Azure Resource Manager Authentication Mode

Note

Local authentication mode is for backward compatibility and has several limitations. It does not support proper auditing for accessing data in deployment. Under local authentication mode, key-value data access inside an ARM template/Bicep/Terraform is disabled if access key authentication is disabled. Azure App Configuration data plane permissions are not required for accessing data under local authentication mode.

Azure App Configuration Authorization

When your App Configuration resource has its Azure Resource Manager authentication mode set to Pass-through, you must have Azure App Configuration data plane permissions to read and manage Azure App Configuration data in deployment. This requirement is in addition to baseline management permission requirements of the resource. Azure App Configuration data plane permissions include Microsoft.AppConfiguration/configurationStores/*/read and Microsoft.AppConfiguration/configurationStores/*/write. Built-in roles with this action include:

  • App Configuration Data Owner
  • App Configuration Data Reader

Private network access

When an App Configuration resource is restricted to private network access, deployments accessing App Configuration data through public networks will be blocked. To enable successful deployments when access to an App Configuration resource is restricted to private networks the following actions must be taken:

  • Azure Resource Management Private Link must be set up
  • The App Configuration resource must have Azure Resource Manager authentication mode set to Pass-through
  • The App Configuration resource must have Azure Resource Manager private network access enabled
  • Deployments accessing App Configuration data must run through the configured Azure Resource Manager private link

If all of these criteria are met, then deployments accessing App Configuration data will be successful.

To enable Azure Resource Manager private network access for an Azure App Configuration resource in the Azure portal, follow these steps:

  1. Navigate to your Azure App Configuration resource in the Azure portal

  2. Locate the Networking setting under Settings

  3. Check Enable Azure Resource Manager Private Access under Private Access

    Screenshot showing Enable Azure Resource Manager Private Access is checked.

Note

Azure Resource Manager private network access can only be enabled under Pass-through authentication mode.
