Quick Start

Node.js

import { ElasticsearchServiceClient, CreateElasticsearchDomainCommand } from '@aws-sdk/client-elasticsearch-service';

const client = new ElasticsearchServiceClient({
  endpoint: 'http://localhost:4566',
  region: 'us-east-1',
  credentials: { accessKeyId: 'test', secretAccessKey: 'test' },
});

await client.send(new CreateElasticsearchDomainCommand({
  DomainName: 'my-domain',
  ElasticsearchVersion: '7.10',
}));

Python

import boto3

client = boto3.client('es',
    endpoint_url='http://localhost:4566',
    region_name='us-east-1',
    aws_access_key_id='test',
    aws_secret_access_key='test')

client.create_elasticsearch_domain(
    DomainName='my-domain',
    ElasticsearchVersion='7.10')

Configuration

cloudmock.yml

services:
  es:
    enabled: true

Known Differences from AWS

• No actual Elasticsearch cluster is provisioned
• Search returns basic in-memory results, not full Elasticsearch query DSL
• Cluster health always reports green
• Consider using the OpenSearch service for new projects
