Lambda code examples for the SDK for Ruby

Overview

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

<!--custom.overview.start--> <!--custom.overview.end-->

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.

Run the examples

Instructions

<!--custom.instructions.start-->

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.

<!--custom.instructions.end-->

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.
<!--custom.basic_prereqs.lambda_Scenario_GettingStartedFunctions.start--> <!--custom.basic_prereqs.lambda_Scenario_GettingStartedFunctions.end-->

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

ruby lambda_basics.rb
<!--custom.basics.lambda_Scenario_GettingStartedFunctions.start--> <!--custom.basics.lambda_Scenario_GettingStartedFunctions.end-->

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.
