Quick Start

Node.js

import { BatchClient, SubmitJobCommand } from '@aws-sdk/client-batch';

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

const { jobId } = await client.send(new SubmitJobCommand({
  jobName: 'my-job',
  jobQueue: 'my-queue',
  jobDefinition: 'my-job-def',
}));
console.log(jobId);

Python

import boto3

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

response = client.submit_job(
    jobName='my-job',
    jobQueue='my-queue',
    jobDefinition='my-job-def')
print(response['jobId'])

Configuration

    enabled: true

Known Differences from AWS

• Jobs are not actually executed on compute resources
• Job status transitions are simulated
• Compute environments do not provision real infrastructure
