AWS SDK for Ruby Version 3 code examples

Overview

The code examples in this topic show you how to use the AWS SDK for Ruby Version 3 with AWS.

The AWS SDK for Ruby Version 3 provides a Ruby API for AWS infrastructure services. Using the SDK, you can build applications on top of Amazon S3, Amazon EC2, Amazon DynamoDB, and more.

Types of code examples

• Single-service actions - Code examples that show you how to call individual service functions.

• Single-service scenarios - Code examples that show you how to accomplish a specific task by calling multiple functions within the same service.

• Cross-service examples - Sample applications that work across multiple AWS services.

Finding code examples

Single-service actions and scenarios are organized by AWS service in the example_code folder. A README in each folder lists and describes how to run the examples.

There are currently no cross-service examples for the AWS SDK for Ruby. To request a cross-service example, create an issue in the AWS SDK Code Examples repo.

⚠️ Important

• Running this code might result in charges to your AWS account.
• 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.

Get started

To begin, you must set up an AWS account and configure credentials locally.

To resolve Ruby-specific dependencies, you must start a command line session and navigate to this directory.

First, verify your version of Ruby is at 3.1 using the following command:

ruby -v

Next, execute the following commands to resolve Gemfile dependencies:

gem install bundler
bundle install

Tests

Note: Running the tests might result in charges to your AWS account.

All tests use RSpec, and you can find them in the spec folder for each example. Please check the README for each service or cross-service example for any additional requirements to run tests.

Unit tests

Note: Running the tests might result in charges to your AWS account.

The unit tests in this module use stubbed responses from AWS SDK for Ruby. This means that when the unit tests are run, requests are not sent to AWS, mocked responses are returned, and no charges are incurred on your account.

Run unit tests in the folder for each service or cross-service example at a command prompt by including the ~integ tag.

rspec --tag ~integ

Integration tests

Note: Running the tests might result in charges to your AWS account.

The integration tests in this module make actual requests to AWS. This means that when the integration tests are run, they can create and destroy resources in your account. These tests might also incur charges. Proceed with caution.

Run integration tests in the folder for each service or cross-service example at a command prompt by including the integ tag.

rspec --tag integ

Docker image (Beta)

This example code will soon be available in a container image hosted on Amazon Elastic Container Registry (ECR). This image will be pre-loaded with all Ruby examples with dependencies pre-resolved, allowing you to explore these examples in an isolated environment.

⚠️ As of January 2023, the SDK for Ruby image is available on ECR Public but is still undergoing active development. Refer to this GitHub issue for more information.
