Lambda >> ElasticSearch >> Kibana

Stability: Experimental

This AWS Solutions Construct implements the AWS Lambda function and Amazon ElasticSearch Service with the least privileged permissions.


Architecture Diagram

Here is a minimal deployable pattern definition in Typescript:

import { LambdaToElasticSearchAndKibana } from 'lambda-elasticsearch-kibana';
import { Aws } from "@aws-cdk/core";

const lambdaProps: lambda.FunctionProps = {
    code: lambda.Code.fromAsset(`${__dirname}/lambda`),
    runtime: lambda.Runtime.NODEJS_14_X,
    handler: 'index.handler'

new LambdaToElasticSearchAndKibana(this, 'test-lambda-elasticsearch-kibana', {
    lambdaFunctionProps: lambdaProps,
    domainName: 'test-domain',
    // TODO: Ensure the Cognito domain name is globally unique
    cognitoDomainName: 'globallyuniquedomain' + Aws.ACCOUNT_ID;


new LambdaToElasticSearchAndKibana(scope: Construct, id: string, props: LambdaToElasticSearchAndKibanaProps);


Pattern Construct Props

Name Type Description
existingLambdaObj? lambda.Function Existing instance of Lambda Function object, providing both this and lambdaFunctionProps will cause an error.
lambdaFunctionProps? lambda.FunctionProps User provided props to override the default props for the Lambda function.
esDomainProps? elasticsearch.CfnDomainProps Optional user provided props to override the default props for the ElasticSearch Service
domainName string Domain name for the Cognito and the ElasticSearch Service
cognitoDomainName? string Optional Cognito Domain Name, if provided it will be used for Cognito Domain, and domainName will be used for the ElasticSearch Domain
createCloudWatchAlarms boolean Whether to create recommended CloudWatch alarms
domainEndpointEnvironmentVariableName? string Optional Name for the ElasticSearch domain endpoint environment variable set for the Lambda function.

Pattern Properties

Name Type Description
lambdaFunction lambda.Function Returns an instance of lambda.Function created by the construct
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
elasticsearchDomain elasticsearch.CfnDomain Returns an instance of elasticsearch.CfnDomain created by the construct
elasticsearchDomain iam.Role Returns an instance of iam.Role created by the construct for elasticsearch.CfnDomain
cloudwatchAlarms? cloudwatch.Alarm[] Returns a list of cloudwatch.Alarm created by the construct

Lambda Function

This pattern requires a lambda function that can post data into the ElasticSearch. A sample function is provided here.

Default settings

Out of the box implementation of the Construct without any override will set the following defaults:

AWS Lambda Function

  • Configure limited privilege access IAM role for Lambda function
  • Enable reusing connections with Keep-Alive for NodeJs Lambda function
  • Enable X-Ray Tracing
  • Set Environment Variables
    • (default) DOMAIN_ENDPOINT
    • AWS_NODEJS_CONNECTION_REUSE_ENABLED (for Node 12.x and higher functions)

Amazon Cognito

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

Amazon ElasticSearch Service

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