Overview

This AWS Solutions Construct implements an AWS Events rule and an AWS SNS Topic.

Here is a minimal deployable pattern definition:

Typescript

import { Construct } from 'constructs';
import { Stack, StackProps, Duration } from 'aws-cdk-lib';
import * as events from 'aws-cdk-lib/aws-events';
import * as iam from 'aws-cdk-lib/aws-iam';
import { EventbridgeToSnsProps, EventbridgeToSns } from "@aws-solutions-constructs/aws-eventbridge-sns";

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

const constructStack = new EventbridgeToSns(this, 'test-construct', constructProps);

// 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);

Python

from aws_solutions_constructs.aws_eventbridge_sns import EventbridgeToSns, EventbridgeToSnsProps
from aws_cdk import (
    aws_events as events,
    aws_iam as iam,
    Duration,
    Stack
)
from constructs import Construct

construct_stack = EventbridgeToSns(self, 'test-construct',
                                    event_rule_props=events.RuleProps(
                                        schedule=events.Schedule.rate(
                                            Duration.minutes(5))
                                    ))

# Grant yourself permissions to use the Customer Managed KMS Key
policy_statement = iam.PolicyStatement(
    actions=["kms:Encrypt", "kms:Decrypt"],
    effect=iam.Effect.ALLOW,
    principals=[iam.AccountRootPrincipal()],
    resources=["*"]
)

Pattern Construct Props

Name	Type	Description
eventRuleProps	`events.RuleProps`	User provided eventRuleProps to override the defaults.
existingTopicObj?	`sns.Topic`	Existing instance of SNS Topic object, providing both this and `topicProps` will cause an error.
topicProps?	`sns.TopicProps`	User provided props to override the default props for the SNS Topic.
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.
enableEncryptionWithCustomerManagedKey?	`boolean`	If no key is provided, this flag determines whether the SNS Topic is encrypted with a new CMK or an AWS managed key. This flag is ignored if any of the following are defined: topicProps.masterKey, encryptionKey or encryptionKeyProps.
encryptionKey?	`kms.Key`	An optional, imported encryption key to encrypt the SNS Topic with.
encryptionKeyProps?	`kms.KeyProps`	Optional user provided properties to override the default properties for the KMS encryption key used to encrypt the SNS Topic with.

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
snsTopic	`sns.Topic`	Returns an instance of sns.Topic created by the construct
encryptionKey?	`kms.Key`	Returns an instance of kms Key used for the SNS Topic.
