Overview

This AWS Solutions Construct implements an AWS Fargate service that can write/read to an Amazon OpenSearch Service domain.

Here is a minimal deployable pattern definition:

Typescript

import { Construct } from 'constructs';
import { Stack, StackProps } from 'aws-cdk-lib';
import { FargateToOpenSearch, FargateToOpenSearchProps } from '@aws-solutions-constructs/aws-fargate-opensearch';

const constructProps: FargateToOpenSearchProps = {
  publicApi: true,
  ecrRepositoryArn: "arn:aws:ecr:us-east-1:123456789012:repository/your-ecr-repo",
  openSearchDomainName: 'testdomain',
  // TODO: Ensure the Cognito domain name is globally unique
  cognitoDomainName: 'globallyuniquedomain' + Aws.ACCOUNT_ID
};

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

Python

from aws_solutions_constructs.aws_fargate_opensearch import FargateToOpenSearch, FargateToOpenSearchProps
from aws_cdk import (
    Stack
)
from constructs import Construct

FargateToOpenSearch(self, 'test_construct',
            public_api=True,
            ecr_repository_arn="arn:aws:ecr:us-east-1:123456789012:repository/your-ecr-repo",
            open_search_domain_name='testdomain',
            # TODO: Ensure the Cognito domain name is globally unique
            cognito_domain_name='globallyuniquedomain' + Aws.ACCOUNT_ID)

Java

import software.constructs.Construct;

import software.amazon.awscdk.Stack;
import software.amazon.awscdk.StackProps;
import software.amazon.awsconstructs.services.fargateopensearch.*;

new FargateToOpenSearch(this, "test_construct", new FargateToOpenSearchProps.Builder()
        .publicApi(true)
        .ecrRepositoryArn("arn:aws:ecr:us-east-1:123456789012:repository/your-ecr-repo"
        .openSearchDomainName("testdomain")
        // TODO: Ensure the Cognito domain name is globally unique
        .cognitoDomainName("globallyuniquedomain" + Aws.ACCOUNT_ID)
        .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.
openSearchDomainProps?	opensearchservice.CfnDomainProps	Optional user provided props to override the default props for the OpenSearch Service.
openSearchDomainName	string	Domain name for the OpenSearch Service.
cognitoDomainName?	string	Optional Amazon Cognito domain name. If omitted the Amazon Cognito domain will default to the OpenSearch Service domain name.
createCloudWatchAlarms?	boolean	Whether to create the recommended CloudWatch alarms.
domainEndpointEnvironmentVariableName?	string	Optional name for the OpenSearch Service domain endpoint environment variable set for the Lambda function. Default is DOMAIN_ENDPOINT.

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.
userPool	cognito.UserPool	Returns an instance of cognito.UserPool created by the construct.
userPoolClient	cognito.UserPoolClient	Returns an instance of cognito.UserPoolClient created by the construct.
identityPool	cognito.CfnIdentityPool	Returns an instance of cognito.CfnIdentityPool created by the construct.
openSearchDomain	opensearchservice.CfnDomain	Returns an instance of opensearch.CfnDomain created by the construct.
openSearchRole	iam.Role	Returns an instance of iam.Role created by the construct for opensearch.CfnDomain.
cloudWatchAlarms?	cloudwatch.Alarm[]	Returns a list of cloudwatch.Alarm 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 OpenSearch Service domain endpoint
  • Add permissions to the container IAM role allowing it to write/read to the OpenSearch Service domain endpoint

Amazon Cognito

• Set password policy for User Pools
• Enforce the advanced security mode for User Pools

Amazon OpenSearch Service

• Deploy best practices CloudWatch Alarms for the OpenSearch Service domain
• Secure the OpenSearch Service dashboard access with Cognito User Pools
• Enable server-side encryption for OpenSearch Service domain using AWS managed KMS Key
• Enable node-to-node encryption for the OpenSearch Service domain
• Configure the cluster for the OpenSearch Service domain
