Overview

This AWS Solutions Construct implements an AWS Fargate service that can write to an Amazon SQS queue

Here is a minimal deployable pattern definition:

Typescript

import { Construct } from 'constructs';
import { Stack, StackProps } from 'aws-cdk-lib';
import { FargateToSqs, FargateToSqsProps } from '@aws-solutions-constructs/aws-fargate-sqs';

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

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

Python

from aws_solutions_constructs.aws_fargate_sqs import FargateToSqs, FargateToSqsProps
from aws_cdk import (
    Stack
)
from constructs import Construct

FargateToSqs(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.fargatesqs.*;

new FargateToSqs(this, "test_construct", new FargateToSqsProps.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
existingQueueObj?	sqs.Queue	An optional, existing SQS queue to be used instead of the default queue. Providing both this and queueProps will cause an error.
queueProps?	sqs.QueueProps	Optional user-provided properties to override the default properties for the SQS queue.
deployDeadLetterQueue?	boolean	Whether to create a secondary queue to be used as a dead letter queue. Defaults to true.
deadLetterQueueProps?	sqs.QueueProps	Optional user-provided props to override the default props for the dead letter queue. Only used if the deployDeadLetterQueue property is set to true.
maxReceiveCount?	integer	The number of times a message can be unsuccessfully dequeued before being moved to the dead letter queue. Defaults to 15.
queueUrlEnvironmentVariableName?	string	Optional Name for the container environment variable set to the URL of the queue. Default: SQS_QUEUE_URL
queueArnEnvironmentVariableName?	string	Optional Name for the container environment variable set to the arn of the queue. Default: SQS_QUEUE_ARN
queuePermissions?	string[]	Optional queue permissions to grant to the Fargate service. One or more of the following may be specified: Read,Write. Default is Write
enableEncryptionWithCustomerManagedKey?	boolean	If no key is provided, this flag determines whether the queue is encrypted with a new CMK or an AWS managed key. This flag is ignored if any of the following are defined: queueProps.encryptionMasterKey, encryptionKey or encryptionKeyProps.
encryptionKey?	kms.Key	An optional, imported encryption key to encrypt the SQS Queue with.
encryptionKeyProps?	kms.KeyProps	Optional user provided properties to override the default properties for the KMS encryption key used to encrypt the SQS queue with.

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.
sqsQueue	sqs.Queue	Returns an instance of the SQS queue created by the pattern.
deadLetterQueue?	sqs.Queue	Returns an instance of the dead letter queue created by the pattern, if one is deployed.

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 SQS queue

  • Add permissions to the container IAM role allowing it to publish to the SQS queue

Amazon SQS Queue

• Sets up an Amazon SQS queue

  • Uses an existing queue if one is provided, otherwise creates a new one

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