Overview
This AWS Solutions Construct implements an AWS Fargate service that can write to an Amazon SNS topic
Here is a minimal deployable pattern definition:
Typescript
import { Construct } from 'constructs';
import { Stack, StackProps } from 'aws-cdk-lib';
import { FargateToSns, FargateToSnsProps } from '@aws-solutions-constructs/aws-fargate-sns';

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

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

Python
from aws_solutions_constructs.aws_fargate_sns import FargateToSns, FargateToSnsProps
from aws_cdk import (
Stack
)
from constructs import Construct

FargateToSns(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.fargatesns.*;

new FargateToSns(this, "test_construct", new FargateToSnsProps.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


existingTopicObj?
sns.Topic
Existing instance of SNS Topic object, providing both this and topicProps will cause an error.


topicProps?
sns.TopicProps
Optional user provided properties to override the default properties for the SNS topic.


topicArnEnvironmentVariableName?
string
Optional Name for the container environment variable set to the ARN of the topic. Default: SNS_TOPIC_ARN


topicNameEnvironmentVariableName?
string
Optional Name for the container environment variable set to the name of the topic. Default: SNS_TOPIC_NAME


enableEncryptionWithCustomerManagedKey?
boolean
If no key is provided, this flag determines whether the SNS Topic is encrypted with a new CMK or an AWS managed key. This flag is ignored if any of the following are defined: topicProps.masterKey, encryptionKey or encryptionKeyProps.


encryptionKey?
kms.Key
An optional, imported encryption key to encrypt the SNS Topic with.


encryptionKeyProps?
kms.KeyProps
Optional user provided properties to override the default properties for the KMS encryption key used to encrypt the SNS Topic 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.


snsTopic
sns.Topic
Returns an instance of the SNS topic created by the pattern.



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 ARN and Name of the SNS topic


Add permissions to the container IAM role allowing it to publish to the SNS topic




Amazon SNS Topic


Sets up an Amazon SNS topic

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



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