Overview

This AWS Solutions Construct implements an AWS Fargate service that can write/read to an AWS Secrets Manager

Here is a minimal deployable pattern definition:

Typescript

import { Construct } from 'constructs';
import { Stack, StackProps } from 'aws-cdk-lib';
import { FargateToSecretsmanager, FargateToSecretsmanagerProps } from '@aws-solutions-constructs/aws-fargate-secretsmanager';

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

new FargateToSecretsmanager(stack, 'test-construct', constructProps);

Python

from aws_solutions_constructs.aws_fargate_secretsmanager import FargateToSecretsmanager, FargateToSecretsmanagerProps
from aws_cdk import (
    Stack
)
from constructs import Construct

FargateToSecretsmanager(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.fargatesecretsmanager.*;

new FargateToSecretsmanager(this, "test-construct", new FargateToSecretsmanagerProps.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	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
secretProps?	secretsmanager.SecretProps	Optional user provided props to override the default props for Secrets Manager
existingSecretObj?	secretsmanager.Secret	Existing instance of Secrets Manager Secret object, If this is set then the secretProps is ignored
grantWriteAccess?	boolean	Optional write access to the Secret for the Fargate service (Read-Only by default)
secretEnvironmentVariableName?	string	Optional Name for the container environment variable set to the ARN of the secret. Default: SECRET_ARN

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.
secret	secretsmanager.Secret	Returns an instance of secretsmanager.Secret created 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 ARN and Name of the Secrets Manager secret

  • Add permissions to the container IAM role allowing it to publish to the Secrets Manager secret

Amazon Secrets Manager Secret

• Sets up an Amazon Secrets Manager secret

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

    • (default) random name
    • (default) random value

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

• Retain the Secret when deleting the CloudFormation stack
