This AWS Solutions Construct implements an Amazon EventBridge rule and an AWS SQS Queue.

Here is a minimal deployable pattern definition in Typescript:

import { Duration } from '@aws-cdk/core';
import * as events from '@aws-cdk/aws-events';
import * as iam from '@aws-cdk/aws-iam';
import { EventbridgeToSqsProps, EventbridgeToSqs } from "@aws-solutions-constructs/aws-eventbridge-sqs";

const props: EventbridgeToSqsProps = {
  eventRuleProps: {
    schedule: events.Schedule.rate(Duration.minutes(5))
  }
};

const constructStack = new EventbridgeToSqs(this, 'test-construct', props);

// Grant yourself permissions to use the Customer Managed KMS Key
const policyStatement = new iam.PolicyStatement({
  actions: ["kms:Encrypt", "kms:Decrypt"],
  effect: iam.Effect.ALLOW,
  principals: [ new iam.AccountRootPrincipal() ],
  resources: [ "*" ]
});

constructStack.encryptionKey?.addToResourcePolicy(policyStatement);

Initializer

new EventbridgeToSqs(scope: Construct, id: string, props: EventbridgeToSqsProps);

Parameters

• scope Construct
• id string
• props EventbridgeToSqsProps

Pattern Construct Props

Name	Type	Description
existingEventBusInterface?	events.IEventBus	Optional user-provided custom EventBus for construct to use. Providing both this and eventBusProps results an error.
eventBusProps?	events.EventBusProps	Optional user-provided properties to override the default properties when creating a custom EventBus. Setting this value to {} will create a custom EventBus using all default properties. If neither this nor existingEventBusInterface is provided the construct will use the default EventBus. Providing both this and existingEventBusInterface results an error.
eventRuleProps	events.RuleProps	User provided eventRuleProps to override the defaults.
existingQueueObj?	sqs.Queue	An optional, existing SQS queue to be used instead of the default queue. Providing both this and queueProps will cause an error.
queueProps?	sqs.QueueProps	User provided props to override the default props for the SQS Queue.
enableQueuePurging?	boolean	Whether to grant additional permissions to the Lambda function enabling it to purge the SQS queue. Defaults to false.
deployDeadLetterQueue?	boolean	Whether to create a secondary queue to be used as a dead letter queue. Defaults to true.
deadLetterQueueProps?	sqs.QueueProps	Optional user-provided props to override the default props for the dead letter queue. Only used if the deployDeadLetterQueue property is set to true.
maxReceiveCount?	number	The number of times a message can be unsuccessfully dequeued before being moved to the dead letter queue. Defaults to 15.
enableEncryptionWithCustomerManagedKey?	boolean	Use a KMS Key, either managed by this CDK app, or imported. If importing an encryption key, it must be specified in the encryptionKey property for this construct.
encryptionKey?	kms.Key	An optional, imported encryption key to encrypt the SQS queue.
encryptionKeyProps?	kms.KeyProps	An optional, user provided properties to override the default properties for the KMS encryption key.

Pattern Properties

Name	Type	Description
eventBus?	events.IEventBus	Returns the instance of events.IEventBus used by the construct
eventsRule	events.Rule	Returns an instance of events.Rule created by the construct
sqsQueue	sqs.Queue	Returns an instance of sqs.Queue created by the construct
encryptionKey?	kms.Key	Returns an instance of kms Key used for the SQS queue.
deadLetterQueue?	sqs.Queue	Returns an instance of the dead-letter SQS queue created by the pattern.

Default settings

Out of the box implementation of the Construct without any override will set the following defaults:

Amazon EventBridge Rule

• Grant least privilege permissions to EventBridge rule to publish to the SQS Queue.

Amazon SQS Queue

• Deploy SQS dead-letter queue for the source SQS Queue.
• Enable server-side encryption for source SQS Queue using Customer managed KMS Key.
• Enforce encryption of data in transit.
