This AWS Solutions Construct implements an AWS Fargate service connected to an Amazon EventBridge.

Here is a minimal deployable pattern definition:

Typescript

import { Construct } from 'constructs';
import { Stack, StackProps } from 'aws-cdk-lib';
import { FargateToEventbridge, FargateToEventbridgeProps } from '@aws-solutions-constructs/aws-fargate-eventbridge';

const constructProps: FargateToEventbridgeProps = {
  publicApi: true,
  ecrRepositoryArn: "arn:aws:ecr:us-east-1:123456789012:repository/your-ecr-repo",
};

new FargateToEventbridge(this, 'test-construct', constructProps);

Python

from aws_solutions_constructs.aws_fargate_eventbridge import FargateToEventbridge, FargateToEventbridgeProps
from aws_cdk import (
    Stack
)
from constructs import Construct

FargateToEventbridge(self, 'test_construct',
            public_api=True,
            ecr_repository_arn="arn:aws:ecr:us-east-1:123456789012:repository/your-ecr-repo")

Java

import software.constructs.Construct;

import software.amazon.awscdk.Stack;
import software.amazon.awscdk.StackProps;
import software.amazon.awsconstructs.services.fargateeventbridge.*;

new FargateToEventbridge(this, "test_construct", new FargateToEventbridgeProps.Builder()
        .publicApi(true)
        .ecrRepositoryArn("arn:aws:ecr:us-east-1:123456789012:repository/your-ecr-repo")
        .build());

Pattern Construct Props

Name	Type	Description
publicApi	boolean	Whether the construct is deploying a private or public API. This has implications for the VPC.
vpcProps?	ec2.VpcProps	Optional custom properties for a VPC the construct will create. This VPC will be used by any Private Hosted Zone the construct creates (that's why loadBalancerProps and privateHostedZoneProps can't include a VPC). Providing both this and existingVpc is an error.
existingVpc?	ec2.IVpc	An existing VPC in which to deploy the construct. Providing both this and vpcProps is an error. If the client provides an existing load balancer and/or existing Private Hosted Zone, those constructs must exist in this VPC.
clusterProps?	ecs.ClusterProps	Optional properties to create a new ECS cluster. To provide an existing cluster, use the cluster attribute of fargateServiceProps.
ecrRepositoryArn?	string	The arn of an ECR Repository containing the image to use to generate the containers. Either this or the image property of containerDefinitionProps must be provided. format: arn:aws:ecr:region:account number:repository/Repository Name
ecrImageVersion?	string	The version of the image to use from the repository. Defaults to 'Latest'
containerDefinitionProps?	[ecs.ContainerDefinitionProps	any](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_ecs.ContainerDefinitionProps.html)
fargateTaskDefinitionProps?	[ecs.FargateTaskDefinitionProps	any](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_ecs.FargateTaskDefinitionProps.html)
fargateServiceProps?	[ecs.FargateServiceProps	any](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_ecs.FargateServiceProps.html)
existingFargateServiceObject?	ecs.FargateService	A Fargate Service already instantiated (probably by another Solutions Construct). If this is specified, then no props defining a new service can be provided, including: ecrImageVersion, containerDefinitionProps, fargateTaskDefinitionProps, ecrRepositoryArn, fargateServiceProps, clusterProps
existingContainerDefinitionObject?	ecs.ContainerDefinition	A container definition already instantiated as part of a Fargate service. This must be the container in the existingFargateServiceObject
existingEventBusInterface?	events.IEventBus	Optional user-provided custom event bus 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 event bus. Setting this value to {} will create a custom event bus using all default properties. If neither this nor existingEventBusInterface is provided the construct will use the default event bus. Providing both this and existingEventBusInterface results an error.
eventBusEnvironmentVariableName?	string	Optional Name for the container environment variable set to the DynamoDB table name. Default: EVENTBUS_NAME

Pattern Properties

Name	Type	Description
vpc	ec2.IVpc	The VPC used by the construct (whether created by the construct or provided by the client)
service	ecs.FargateService	The AWS Fargate service used by this construct (whether created by this construct or passed to this construct at initialization)
container	ecs.ContainerDefinition	The container associated with the AWS Fargate service in the service property.
eventBus?	events.IEventBus	Returns the instance of events.IEventBus used by the construct

Default settings

Out of the box implementation of the Construct without any override will set the following defaults:

AWS Fargate Service

• Sets up an AWS Fargate service

  • Uses the existing service if provided

  • Creates a new service if none provided.

    • Service will run in isolated subnets if available, then private subnets if available and finally public subnets

• Adds environment variables to the container with the Name of the event bus

  • Default: EVENTBUS_NAME

• Add permissions to the container IAM role allowing it to put events in the EventBridge event bus

Amazon EventBridge Event Bus

• Sets up an Amazon EventBridge event bus

  • Uses an existing event bus if one is provided, otherwise creates a new one if eventBusProps is provided
  • If neither eventBusProps nor existingEventBusInterface is provided, the construct will use the default event bus.

• Adds an Interface Endpoint to the VPC for EventBridge (the service by default runs in Isolated or Private subnets)
