Quick Start

Node.js

import { DatabaseMigrationServiceClient, CreateReplicationInstanceCommand } from '@aws-sdk/client-database-migration-service';

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

await client.send(new CreateReplicationInstanceCommand({
  ReplicationInstanceIdentifier: 'my-repl-instance',
  ReplicationInstanceClass: 'dms.t3.medium',
}));

Python

import boto3

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

client.create_replication_instance(
    ReplicationInstanceIdentifier='my-repl-instance',
    ReplicationInstanceClass='dms.t3.medium')

Configuration

cloudmock.yml

services:
  dms:
    enabled: true

Known Differences from AWS

• No actual data migration occurs
• Connection tests return stub success results
• Replication task status transitions are simulated
