Quick Start

Node.js

import { MemoryDBClient, CreateClusterCommand } from '@aws-sdk/client-memorydb';

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

await client.send(new CreateClusterCommand({
  ClusterName: 'my-memorydb',
  NodeType: 'db.r6g.large',
  ACLName: 'open-access',
}));

Python

import boto3

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

client.create_cluster(
    ClusterName='my-memorydb',
    NodeType='db.r6g.large',
    ACLName='open-access')

Configuration

cloudmock.yml

services:
  memorydb:
    enabled: true

Known Differences from AWS

• No actual Redis engine is provisioned
• Cluster endpoints are generated but not functional
• Snapshots are metadata-only
