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=["*"]
)

construct_stack.encryption_key.add_to_resource_policy(policy_statement)

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.|

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 SNS Topic.

Amazon SNS Topic

• Configure least privilege access permissions for SNS Topic.
• Enable server-side encryption forSNS Topic using Customer managed KMS Key.
• Enforce encryption of data in transit.
