Overview

This AWS Solutions Construct deploys an AWS Fargate Service that can put records on an Amazon Firehose Delivery Stream.

Here is a minimal deployable pattern definition:

Typescript

import { Construct } from 'constructs';
import { Stack, StackProps } from 'aws-cdk-lib';
import { FargateToKinesisFirehoseProps } from '@aws-solutions-constructs/aws-fargate-kinesisfirehose';
import * as fargate from 'aws-cdk-lib/aws-fargate';

// The construct requires an existing Firehose Delivery Stream, this can be created in raw CDK or extracted
// from a previously instantiated construct that created an Firehose Delivery Stream
const existingFirehoseDeliveryStream = previouslyCreatedKinesisFirehoseToS3Construct.kinesisFirehose;

new FargateToKinesisFirehose(this, 'FargateToKinesisFirehose', {
  publicApi: true,
  ecrRepositoryArn: "arn:aws:ecr:us-east-1:123456789012:repository/your-ecr-repo",
  existingKinesisFirehose: existingFirehoseDeliveryStream
});

Python

from aws_solutions_constructs.aws_fargate_kinesisfirehose import FargateToKinesisFirehose
from aws_cdk import (
    aws_fargate as _fargate,
    Stack
)
from constructs import Construct

# The construct requires an existing Firehose Delivery Stream, this can be created in raw CDK or extracted
# from a previously instantiated construct that created an Firehose Delivery Stream
existingFirehoseDeliveryStream = previouslyCreatedKinesisFirehoseToS3Construct.kinesisFirehose;

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

Java

import software.constructs.Construct;
import software.amazon.awscdk.Stack;
import software.amazon.awscdk.StackProps;
import software.amazon.awscdk.services.fargate.*;
import software.amazon.awscdk.services.fargate.eventsources.*;

import software.amazon.awsconstructs.services.fargatekinesisfirehose.*;

// The construct requires an existing Firehose Delivery Stream, this can be created in raw CDK or extracted
// from a previously instantiated construct that created an Firehose Delivery Stream
existingFirehoseDeliveryStream = previouslyCreatedKinesisFirehoseToS3Construct.kinesisFirehose;

new FargateToKinesisFirehose(this, "FargateToKinesisFirehose", new FargateToKinesisFirehoseProps.Builder()
        .publicApi(true)
        .ecrRepositoryArn("arn:aws:ecr:us-east-1:123456789012:repository/your-ecr-repo")
        .existingKinesisFirehose(existingFirehoseDeliveryStream)
        .build());

Pattern Construct Props

Name Type Description
publicApi boolean True if the VPC provisioned by this construct should contain Public/Private Subnets, otherwise False for the VPC to contain Isolated Subnets only. Note this property is ignored if an existing VPC is specified in the existingVpc property. If you are getting a container from a public repo, this must be true so the repo can be accessed from the network.
vpcProps? ec2.VpcProps Optional custom properties for a new VPC the construct will create. Providing both this and existingVpc is an error. An Amazon Kinesis Firehose Interface Endpoint will be added to this VPC.
existingVpc? ec2.IVpc An existing VPC in which to deploy the Fargate Service. Providing both this and vpcProps is an error. If the client provides an existing Fargate Service in the existingFargateServiceObject property, this value must be the VPC where the service is running. An Amazon Kinesis Firehose Interface Endpoint will be added to 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 Optional props to define the container created for the Fargate Service. (defaults found in fargate-defaults.ts)
fargateTaskDefinitionProps? ecs.FargateTaskDefinitionProps | any Optional props to define the Fargate Task Definition for this construct. (defaults found in fargate-defaults.ts)
fargateServiceProps? ecs.FargateServiceProps | any Optional values to override default Fargate Task definition properties (fargate-defaults.ts). The construct will default to launching the service is the most isolated subnets available (precedence: Isolated, Private and Public). Override those and other defaults here.
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.
existingKinesisFirehose kinesisfirehose.CfnDeliveryStream An existing Kinesis Firehose Delivery Stream to which the Fargate container can put data. Note - the delivery stream construct must have already been created and have the deliveryStreamName set. This construct will not create a new Delivery Stream.
firehoseEnvironmentVariableName? string Optional Name for the Fargate container environment variable set to the name of the delivery stream. Default: FIREHOSE_DELIVERYSTREAM_NAME

Pattern Properties

Name Type Description
vpc ec2.IVpc The new or existing VPC used by the construct.
fargateService ecs.FargateService The new or existing AWS Fargate service used by this construct.
container ecs.ContainerDefinition The container associated with the AWS Fargate service in the service property.
kinesisFirehose kinesisfirehose.CfnDeliveryStream The Kinesis Firehose Delivery Stream used by the construct.

Default settings

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

AWS Fargate Service

  • An AWS Fargate Service running in the isolated subnets of a new VPC
  • Minimally-permissive IAM role for the Fargate Service to put records on the Firehose Delivery Stream
  • Sets an Environment Variable named FIREHOSE_DELIVERYSTREAM_NAME that holds the Firehose Delivery Stream Name, which is a required property of the Kinesis Firehose SDK when making calls to it

Amazon Firehose Delivery Stream

  • This construct must be provided a configured Firehose Data Stream construct, it does not change this Stream.
