Quick Start

Node.js

import { ServiceDiscoveryClient, CreateHttpNamespaceCommand, CreateServiceCommand } from '@aws-sdk/client-servicediscovery';

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

const { OperationId } = await client.send(new CreateHttpNamespaceCommand({
  Name: 'my-namespace',
}));

await client.send(new CreateServiceCommand({
  Name: 'my-service',
  NamespaceId: 'ns-12345',
}));

Python

import boto3

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

client.create_http_namespace(Name='my-namespace')
client.create_service(Name='my-service', NamespaceId='ns-12345')

Configuration

cloudmock.yml

services:
  servicediscovery:
    enabled: true

Known Differences from AWS

• DNS namespaces do not create actual Route 53 hosted zones
• Instance discovery returns registered instances without health filtering
• Custom health status updates are stored but not used for filtering
