Quick Start

Node.js

import { ElasticBeanstalkClient, CreateApplicationCommand, CreateApplicationVersionCommand, CreateEnvironmentCommand } from '@aws-sdk/client-elastic-beanstalk';

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

await client.send(new CreateApplicationCommand({ ApplicationName: 'my-app' }));

await client.send(new CreateApplicationVersionCommand({
  ApplicationName: 'my-app',
  VersionLabel: 'v1.0.0',
  SourceBundle: { S3Bucket: 'my-bucket', S3Key: 'app-v1.zip' },
}));

await client.send(new CreateEnvironmentCommand({
  ApplicationName: 'my-app',
  EnvironmentName: 'my-env',
  VersionLabel: 'v1.0.0',
  SolutionStackName: '64bit Amazon Linux 2023 v6.0.0 running Node.js 18',
}));

Python

import boto3

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

client.create_application(ApplicationName='my-app')
client.create_application_version(
    ApplicationName='my-app',
    VersionLabel='v1.0.0',
    SourceBundle={'S3Bucket': 'my-bucket', 'S3Key': 'app-v1.zip'})
client.create_environment(
    ApplicationName='my-app',
    EnvironmentName='my-env',
    VersionLabel='v1.0.0')

Configuration

cloudmock.yml

services:
  elasticbeanstalk:
    enabled: true

Known Differences from AWS

• No actual infrastructure is provisioned for environments
• Environment health transitions are simulated
• Application deployments are not executed
• ValidateConfigurationSettings always returns zero messages (all valid)
• ListPlatformVersions returns a static list of common platforms
