Overview

This AWS Solutions Construct implements an AWS Events rule and an AWS Step Functions State Machine

Here is a minimal deployable pattern definition:

Typescript

import { Construct } from 'constructs';
import { Stack, StackProps, Duration } from 'aws-cdk-lib';
import { EventbridgeToStepfunctions, EventbridgeToStepfunctionsProps } from '@aws-solutions-constructs/aws-eventbridge-stepfunctions';
import * as stepfunctions from 'aws-cdk-lib/aws-stepfunctions';
import * as events from 'aws-cdk-lib/aws-events';

const startState = new stepfunctions.Pass(this, 'StartState');

const constructProps: EventbridgeToStepfunctionsProps = {
  stateMachineProps: {
    definition: startState
  },
  eventRuleProps: {
    schedule: events.Schedule.rate(Duration.minutes(5))
  }
};

new EventbridgeToStepfunctions(this, 'test-eventbridge-stepfunctions-stack', constructProps);

Python

from aws_solutions_constructs.aws_eventbridge_stepfunctions import EventbridgeToStepfunctions, EventbridgeToStepfunctionsProps
from aws_cdk import (
    aws_stepfunctions as stepfunctions,
    aws_events as events,
    Duration,
    Stack
)
from constructs import Construct

startState = stepfunctions.Pass(self, 'StartState')

EventbridgeToStepfunctions(self, 'test-eventbridge-stepfunctions-stack',
                            state_machine_props=stepfunctions.StateMachineProps(
                                definition=startState
                            ),
                            event_rule_props=events.RuleProps(
                                schedule=events.Schedule.rate(
                                    Duration.minutes(5))
                            ))

Pattern Construct Props

Name	Type	Description
stateMachineProps	`sfn.StateMachineProps`	Optional user provided props to override the default props for sfn.StateMachine
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
createCloudWatchAlarms	`boolean`	Whether to create recommended CloudWatch alarms
logGroupProps?	`logs.LogGroupProps`	User provided props to override the default props for for the CloudWatchLogs LogGroup.

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
stateMachine	`sfn.StateMachine`	Returns an instance of sfn.StateMachine created by the construct
stateMachineLogGroup	`logs.ILogGroup`	Returns an instance of the ILogGroup created by the construct for StateMachine
cloudwatchAlarms?	`cloudwatch.Alarm[]`	Returns a list of cloudwatch.Alarm created by the construct
