Component format

To setup Azure Storage Queues binding create a component of type bindings.azure.storagequeues. See [this guide]({{< ref "howto-bindings.md#1-create-a-binding" >}}) on how to create and apply a binding configuration.

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: <NAME>
spec:
  type: bindings.azure.storagequeues
  version: v1
  metadata:
  - name: accountName
    value: "account1"
  - name: accountKey
    value: "***********"
  - name: queueName
    value: "myqueue"
# - name: pollingInterval
#   value: "30s"
# - name: ttlInSeconds
#   value: "60"
# - name: decodeBase64
#   value: "false"
# - name: encodeBase64
#   value: "false"
# - name: endpoint
#   value: "http://127.0.0.1:10001"
# - name: visibilityTimeout
#   value: "30s"
# - name: direction 
#   value: "input, output"

{{% alert title="Warning" color="warning" %}} The above example uses secrets as plain strings. It is recommended to use a secret store for the secrets as described [here]({{< ref component-secrets.md >}}). {{% /alert %}}

Spec metadata fields

Field	Required	Binding support	Details	Example
accountName	Y	Input/Output	The name of the Azure Storage account	"account1"
accountKey	Y*	Input/Output	The access key of the Azure Storage account. Only required when not using Azure AD authentication.	"access-key"
queueName	Y	Input/Output	The name of the Azure Storage queue	"myqueue"
pollingInterval	N	Output	Set the interval to poll Azure Storage Queues for new messages, as a Go duration value. Default: "10s"	"30s"
ttlInSeconds	N	Output	Parameter to set the default message time to live. If this parameter is omitted, messages will expire after 10 minutes. See also	"60"
decodeBase64	N	Input	Configuration to decode base64 content received from the Storage Queue into a string. Defaults to false	true, false
encodeBase64	N	Output	If enabled base64 encodes the data payload before uploading to Azure storage queues. Default false.	true, false
endpoint	N	Input/Output	Optional custom endpoint URL. This is useful when using the Azurite emulator or when using custom domains for Azure Storage (although this is not officially supported). The endpoint must be the full base URL, including the protocol (http:// or https://), the IP or FQDN, and optional port.	"http://127.0.0.1:10001" or "https://accountName.queue.example.com"
visibilityTimeout	N	Input	Allows setting a custom queue visibility timeout to avoid immediate retrying of recently failed messages. Defaults to 30 seconds.	"100s"
direction	N	Input/Output	Direction of the binding.	"input", "output", "input, output"

Azure Active Directory (Azure AD) authentication

The Azure Storage Queue binding component supports authentication using all Azure Active Directory mechanisms. See the [docs for authenticating to Azure]({{< ref authenticating-azure.md >}}) to learn more about the relevant component metadata fields based on your choice of Azure AD authentication mechanism.

Binding support

This component supports both input and output binding interfaces.

This component supports output binding with the following operations:

• create

Specifying a TTL per message

Time to live can be defined on queue level (as illustrated above) or at the message level. The value defined at message level overwrites any value set at queue level.

To set time to live at message level use the metadata section in the request body during the binding invocation.

The field name is ttlInSeconds.

Example:

curl -X POST http://localhost:3500/v1.0/bindings/myStorageQueue \
  -H "Content-Type: application/json" \
  -d '{
        "data": {
          "message": "Hi"
        },
        "metadata": {
          "ttlInSeconds": "60"
        },
        "operation": "create"
      }'
