Lambda code examples for the SDK for Ruby

Overview

Shows how to use the AWS SDK for Ruby to work with AWS Lambda.

Lambda allows you to run code without provisioning or managing servers.

⚠ Important

  • Running this code might result in charges to your AWS account. For more details, see AWS Pricing and Free Tier.
  • Running the tests might result in charges to your AWS account.
  • We recommend that you grant your code least privilege. At most, grant only the minimum permissions required to perform the task. For more information, see Grant least privilege.
  • This code is not tested in every AWS Region. For more information, see AWS Regional Services.

Code examples

Prerequisites

For prerequisites, see the README in the ruby folder.

Get started

Basics

Code examples that show you how to perform the essential operations within a service.

Single actions

Code excerpts that show you how to call individual service functions.

Run the examples

Instructions

The quickest way to interact with this example code is to invoke a Scenario from your command line. For example, ruby some_scenario.rb will invoke some_scenario.rb.

Hello Lambda

This example shows you how to get started using Lambda.

ruby hello/hello_lambda.rb

Learn the basics

This example shows you how to do the following:

  • Create an IAM role and Lambda function, then upload handler code.
  • Invoke the function with a single parameter and get results.
  • Update the function code and configure with an environment variable.
  • Invoke the function with new parameters and get results. Display the returned execution log.
  • List the functions for your account, then clean up resources.

Start the example by running the following at a command prompt:

ruby lambda_basics.rb

Tests

⚠ Running tests might result in charges to your AWS account.

To find instructions for running these tests, see the README in the ruby folder.
