Overview

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

Here is a minimal deployable pattern definition:

Typescript

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

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

Python

from aws_solutions_constructs.aws_fargate_kinesisstreams import FargateToKinesisStreams
from aws_cdk import (
    aws_fargate as _fargate,
    Stack
)
from constructs import Construct

FargateToKinesisStreams(self, 'FargateToKinesisStreams',
                          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.awscdk.services.fargate.*;
import software.amazon.awscdk.services.fargate.eventsources.*;
import software.amazon.awscdk.services.fargate.Runtime;
import software.amazon.awsconstructs.services.fargatekinesisstreams.*;

new FargateToKinesisStreams(this, "FargateToKinesisStreams", new FargateToKinesisStreamsProps.Builder()
        .publicApi(true)
        .ecrRepositoryArn("arn:aws:ecr:us-east-1:123456789012:repository/your-ecr-repo")
        .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.
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 Streams 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 Streams 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.
existingStreamObj?	kinesis.Stream	Existing instance of a Kinesis Data Stream. Providing both this and kinesisStreamProps will cause an error.
kinesisStreamProps?	kinesis.StreamProps	Optional user-provided props to override the default props for the Kinesis Data Stream. Providing both this and existingStreamObj will cause an error.
createCloudWatchAlarms	boolean	Whether to create recommended CloudWatch Alarms for the Kinesis Stream (defaults to true).
streamEnvironmentVariableName?	string	Optional Name to override the Fargate Service default environment variable name that holds the Kinesis Data Stream name value. Default: KINESIS_DATASTREAM_NAME

Pattern Properties

Name	Type	Description
vpc	ec2.IVpc	The new or existing VPC used by the construct.
service	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.
kinesisStream	kinesis.Stream	The new or existing Kinesis Data Stream used by this construct.
cloudwatchAlarms?	cloudwatch.Alarm[]	Returns the CloudWatch Alarms created to monitor the Kinesis Data Stream.

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 Kinesis Data Stream
• Sets an Environment Variable named KINESIS_DATASTREAM_NAME that holds the Kinesis Data Stream Name, which is a required property of the Kinesis Data Streams SDK when making calls to it

Amazon Kinesis Stream

• Enable server-side encryption for the Kinesis Data Stream using an AWS Managed CMK
• Deploy best practices CloudWatch Alarms for the Kinesis Data Stream
• An Interface Endpoint on the VPC for private communication between the Fargate Service and the Kinesis Data Stream
