Overview
This AWS Solutions Construct implements an AWS EventBridge rule and an AWS Lambda function.
Here is a minimal deployable pattern definition:
Typescript
import { Construct } from 'constructs';
import { Stack, StackProps, Duration } from 'aws-cdk-lib';
import { EventbridgeToLambdaProps, EventbridgeToLambda } from '@aws-solutions-constructs/aws-eventbridge-lambda';
import * as lambda from 'aws-cdk-lib/aws-lambda';
import * as events from 'aws-cdk-lib/aws-events';

const constructProps: EventbridgeToLambdaProps = {
lambdaFunctionProps: {
code: lambda.Code.fromAsset(`lambda`),
runtime: lambda.Runtime.NODEJS_16_X,
handler: 'index.handler'
},
eventRuleProps: {
schedule: events.Schedule.rate(Duration.minutes(5))
}
};

new EventbridgeToLambda(this, 'test-eventbridge-lambda', constructProps);

Python
from aws_solutions_constructs.aws_eventbridge_lambda import EventbridgeToLambda, EventbridgeToLambdaProps
from aws_cdk import (
aws_lambda as _lambda,
aws_events as events,
Duration,
Stack
)
from constructs import Construct

EventbridgeToLambda(self, 'test-eventbridge-lambda',
lambda_function_props=_lambda.FunctionProps(
code=_lambda.Code.from_asset('lambda'),
runtime=_lambda.Runtime.PYTHON_3_9,
handler='index.handler'
),
event_rule_props=events.RuleProps(
schedule=events.Schedule.rate(
Duration.minutes(5))
))

Java
import software.constructs.Construct;

import software.amazon.awscdk.Stack;
import software.amazon.awscdk.StackProps;
import software.amazon.awscdk.Duration;
import software.amazon.awscdk.services.events.*;
import software.amazon.awscdk.services.lambda.*;
import software.amazon.awscdk.services.lambda.Runtime;
import software.amazon.awsconstructs.services.eventbridgelambda.*;

new EventbridgeToLambda(this, "test-eventbridge-lambda",
new EventbridgeToLambdaProps.Builder()
.lambdaFunctionProps(new FunctionProps.Builder()
.runtime(Runtime.NODEJS_16_X)
.code(Code.fromAsset("lambda"))
.handler("index.handler")
.build())
.eventRuleProps(new RuleProps.Builder()
.schedule(Schedule.rate(Duration.minutes(5)))
.build())
.build());

Pattern Construct Props



Name
Type
Description




existingLambdaObj?
lambda.Function
Existing instance of Lambda Function object, providing both this and lambdaFunctionProps will cause an error.


lambdaFunctionProps?
lambda.FunctionProps
User provided props to override the default props for the Lambda function.


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



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


lambdaFunction
lambda.Function
Returns an instance of lambda.Function created by the construct



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 trigger the Lambda Function

AWS Lambda Function

Configure limited privilege access IAM role for Lambda function
Enable reusing connections with Keep-Alive for NodeJs Lambda function
Enable X-Ray Tracing
Set Environment Variables
AWS_NODEJS_CONNECTION_REUSE_ENABLED (for Node 10.x and higher functions)
