Component format

To setup Azure Service Bus Queues binding create a component of type bindings.azure.servicebusqueues. 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>
  namespace: <NAMESPACE>
spec:
  type: bindings.azure.servicebusqueues
  version: v1
  metadata:
  - name: connectionString
    value: "Endpoint=sb://************"
  - name: queueName
    value: queue1
  - name: ttlInSeconds
    value: 60

{{% 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
connectionString	Y	Input/Output	The Service Bus connection string	"Endpoint=sb://************"
queueName	Y	Input/Output	The Service Bus queue name. Queue names are case-insensitive and will always be forced to lowercase.	"queuename"
ttlInSeconds	N	Output	Parameter to set the default message time to live. If this parameter is omitted, messages will expire after 14 days. See also	"60"

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.
