How to Create an OpenSearch Index Using CDK

Introduction to OpenSearch and AWS CDK

OpenSearch is an open-source search and analytics suite derived from Elasticsearch, designed for high scalability and performance. AWS CDK, or Cloud Development Kit, is a software development framework that allows developers to define cloud infrastructure using familiar programming languages like TypeScript, Python, and Java. In this blog, we will guide you on how to create an OpenSearch index using AWS CDK effectively.

Prerequisites for Setting Up OpenSearch

Before you begin creating an OpenSearch index, ensure you have the following prerequisites in place. Understanding these will streamline your setup process.

Key Prerequisites

• AWS account with necessary permissions
• Node.js installed on your local machine
• AWS CDK Toolkit installed globally
• Familiarity with TypeScript or your preferred programming language

Setting Up Your AWS CDK Project

After ensuring your environment is ready, the next step involves initializing your AWS CDK project. This process lays the foundation for your infrastructure deployment.

Initialize AWS CDK Project

mkdir my-opensearch-project
cd my-opensearch-project
cdk init app --language=typescript

Installing Necessary Dependencies

With your project initialized, you need to install the AWS CDK OpenSearch module to leverage its functionalities. This step is crucial for accessing OpenSearch-specific resources.

Install OpenSearch Module

npm install @aws-cdk/aws-opensearchservice

Creating the OpenSearch Index

Now that everything is set up, it's time to create the OpenSearch index. This involves defining the index creation parameters and deploying it.

CloudFormation for OpenSearch Index

import * as opensearch from '@aws-cdk/aws-opensearchservice';

const openSearchDomain = new opensearch.CfnDomain(this, 'MyOpenSearchDomain', {
 domainName: 'my-domain',
 elasticsearchClusterConfig: {
 instanceType: 't2.medium.search',
 instanceCount: 1
 },
 ebsOptions: {
 ebsEnabled: true,
 volumeSize: 10,
 }
});

Deploying Your OpenSearch Index

Once your OpenSearch index is defined in code, the next step is to deploy it to AWS. This process will create the infrastructure as per your configuration.

Deploy Your CDK App

cdk deploy

Testing the OpenSearch Index

After deployment, it's important to verify that your OpenSearch index was created successfully. You can use various tools like Postman or CURL to test your endpoint.

Sample CURL Command for Testing

curl -X GET 'https://my-domain.region.es.amazonaws.com/_cat/indices?v'
