Creating an EventBridge Rule That Triggers on a Schedule - Amazon EventBridge

Creating an EventBridge Rule That Triggers on a Schedule

Use the following steps to create an EventBridge rule that triggers on a regular schedule. You can create scheduled rules only using the default event bus.

To create a rule that triggers on a regular schedule

  1. Open the Amazon EventBridge console at https://console.aws.amazon.com/events/.

  2. In the navigation pane, choose Rules.

  3. Choose Create rule.

  4. Enter a name and description for the rule.

    A rule can't have the same name as another rule in the same Region and on the same event bus.

  5. For Define pattern, choose Schedule.

  6. Either choose Fixed rate of and specify how often the task is to run, or choose Cron expression and specify a cron expression that defines when the task is to be triggered. For more information about cron expression syntax, see Schedule Expressions for Rules.

  7. For Select event bus, choose AWS default event bus. Scheduled rules are supported only on the default event bus.

  8. For Select targets, choose the AWS service that is to act on the specified schedule.

  9. In the other fields in this section, enter information specific to this target type, if any is needed.

  10. For many target types, EventBridge needs permissions to send events to the target. In these cases, EventBridge can create the IAM role needed for your rule to run:

    • To create an IAM role automatically, choose Create a new role for this specific resource

    • To use an IAM role that you created before, choose Use existing role

  11. For Retry policy and dead-letter queue:, under Retry policy:

    1. For Maximum age of event, enter a value between 1 minute (00:01) and 24 hours (24:00).

    2. For Retry attempts, enter a number between 0 and 185.

  12. For Dead-letter queue, choose whether to use a standard Amazon SQS queue as a dead-letter queue. EventBridge sends events that match this rule to the dead-letter queue if they are not successfully delivered to the target. Do one of the following:

    • Choose None to not use a dead-letter queue.

    • Choose Select an Amazon SQS queue in the current AWS account to use as the dead-letter queue and then select the queue to use from the drop-down list.

    • Choose Select an Amazon SQS queue in an other AWS account as a dead-letter queue and then enter the ARN of the queue to use. You must attach a resource-based policy to the queue that grants EventBridge permission to send messages to it. To learn more, see Granting permissions to the DLQ.

  13. (Optional) Choose Add target to add another target for this rule.

  14. (Optional) Enter one or more tags for the rule. For more information, see Tagging Your Amazon EventBridge Resources.

  15. Choose Create.
