Azure App Configuration
To set up an Azure App Configuration configuration store, create a component of type
apiVersion: dapr.io/v1alpha1 kind: Component metadata: name: <NAME> spec: type: configuration.azure.appconfig version: v1 metadata: - name: host # host should be used when Azure Authentication mechanism is used. value: <HOST> - name: connectionString # connectionString should not be used when Azure Authentication mechanism is used. value: <CONNECTIONSTRING> - name: maxRetries value: # Optional - name: retryDelay value: # Optional - name: maxRetryDelay value: # Optional - name: azureEnvironment # Optional, defaults to AZUREPUBLICCLOUD value: "AZUREPUBLICCLOUD" # See authentication section below for all options - name: azureTenantId # Optional value: "[your_service_principal_tenant_id]" - name: azureClientId # Optional value: "[your_service_principal_app_id]" - name: azureCertificateFile # Optional value : "[pfx_certificate_file_fully_qualified_local_path]" - name: subscribePollInterval # Optional value: #Optional [Expected format example - 1s|1m|1h]
WarningThe above example uses secrets as plain strings. It is recommended to use a secret store for the secrets as described here.
Spec metadata fields
|connectionString||Y*||Connection String for the Azure App Configuration instance. No Default. Can be
|host||N*||Endpoint for the Azure App Configuration instance. No Default. *Mutally exclusive with connectionString field. *To be used when Azure Authentication is used||
|maxRetries||N||Maximum number of retries before giving up. Defaults to
|retryDelay||N||RetryDelay specifies the initial amount of delay to use before retrying an operation. The delay increases exponentially with each retry up to the maximum specified by MaxRetryDelay. Defaults to
|maxRetryDelay||N||MaxRetryDelay specifies the maximum delay allowed before retrying an operation. Typically the value is greater than or equal to the value specified in RetryDelay. Defaults to
|subscribePollInterval||N||subscribePollInterval specifies the poll interval for polling the subscribed keys for any changes. Default polling interval is set to
connectionString must be specified.
Authenticating with Connection String
Access an App Configuration instance using its connection string, which is available in the Azure portal. Since connection strings contain credential information, you should treat them as secrets and use a secret store.
Authenticating with Azure AD
The Azure App Configuration configuration store component also supports authentication with Azure AD. Before you enable this component:
- Read the Authenticating to Azure document.
- Create an Azure AD application (also called Service Principal).
- Alternatively, create a managed identity for your application platform.
Set up Azure App Configuration
You need an Azure subscription to set up Azure App Configuration.
Start the Azure App Configuration creation flow. Log in if necessary.
Click Create to kickoff deployment of your Azure App Configuration instance.
Once your instance is created, grab the Host (Endpoint) or your Connection string:
- For the Host: navigate to the resource’s Overview and copy Endpoint.
- For your connection string: navigate to Settings > Access Keys and copy your Connection string.
Add your host or your connection string to an
azappconfig.yamlfile that Dapr can apply.
connectionStringkey to the values you saved earlier.
NoteIn a production-grade application, follow the secret management instructions to securely manage your secrets.
Azure App Configuration request metadata
In Azure App Configuration, you can use labels to define different values for the same key. For example, you can define a single key with different values for development and production. You can specify which label to load when connecting to App Configuration
The Azure App Configuration store component supports the following optional
label metadata property:
label: The label of the configuration to retrieve. If not present, the configuration store returns the configuration for the specified key and a null label.
The label can be populated using query parameters in the request URL:
GET curl http://localhost:<daprPort>/v1.0-alpha1/configuration/<store-name>?key=<key name>&metadata.label=<label value>
