How Do I Create an AWS OpenSearch Domain Policy?

Introduction

Managing access to your AWS OpenSearch domain is crucial for maintaining security and ensuring that only authorized users and services can interact with it. In this guide, we will walk through the process of creating an AWS OpenSearch domain policy using Pulumi in TypeScript. This will involve defining the domain and setting up access control rules to protect your resources.

Key Points

• Define an OpenSearch domain.
• Create a domain policy to manage access control.
• Use Pulumi to manage the infrastructure as code.

Step-by-Step Guide

1. Define the OpenSearch Domain: Begin by setting up your OpenSearch domain with the necessary configurations, such as the domain name, engine version, and cluster settings.

2. Create a Domain Policy: Develop a policy that specifies who can access the domain and what actions they can perform. This involves defining the access policies that will be applied to the domain.

3. Use Pulumi for Infrastructure Management: Implement the domain and its policy using Pulumi, which allows you to manage your infrastructure as code, ensuring consistency and repeatability.

Below is the Pulumi program to create an AWS OpenSearch domain and apply a domain policy:

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

// Define the OpenSearch domain
const domain = new aws.opensearch.Domain("myDomain", {
    domainName: "example-domain",
    engineVersion: "OpenSearch_1.0",
    clusterConfig: {
        instanceType: "m6g.large.search",
        instanceCount: 2,
    },
    ebsOptions: {
        ebsEnabled: true,
        volumeSize: 10,
        volumeType: "gp2",
    },
    accessPolicies: pulumi.output({
        Version: "2012-10-17",
        Statement: [{
            Effect: "Allow",
            Principal: {
                AWS: "*"
            },
            Action: "es:*",
            Resource: "arn:aws:es:us-west-2:123456789012:domain/example-domain/*"
        }]
    }).apply(JSON.stringify),
});

// Create the domain policy
const domainPolicy = new aws.opensearch.DomainPolicy("myDomainPolicy", {
    domainName: domain.domainName,
    accessPolicies: domain.accessPolicies,
});

// Export the domain endpoint
export const domainEndpoint = domain.endpoint;

Summary

In this guide, we successfully created an AWS OpenSearch domain and applied a domain policy using Pulumi in TypeScript. By defining access control rules, we ensure that the OpenSearch domain is secure and accessible only to authorized users and services. This approach not only enhances security but also simplifies the management of your infrastructure through code.
