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

Here is a minimal deployable pattern definition in Typescript:

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
from aws_cdk.core import Duration
import aws_cdk.aws_events as events
import aws_cdk.aws_iam as iam
from aws_solutions_constructs.aws_events_rule_sns import EventsRuleToSnsProps, EventsRuleToSns

props = EventsRuleToSnsProps(
    event_rule_props=RuleProps(
        schedule=events.Schedule.rate(Duration.minutes(5))
    )
)

construct_stack = EventsRuleToSns(self, "test-construct", props)

# 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)

Initializer

new EventsRuleToSns(scope: Construct, id: string, props: EventsRuleToSnsProps);
