The official AWS SDK for Ruby.

Version 1 of the AWS SDK for Ruby is available on rubygems.org as two gems:

• aws-sdk-v1
• aws-sdk

This project uses semantic versioning. If you are using the aws-sdk gem, we strongly recommend you specify a version constraint in your Gemfile. Version 2 of the Ruby SDK will not be backwards compatible with version 1.

# version constraint
gem 'aws-sdk', '< 2'

# or use the v1 gem
gem 'aws-sdk-v1'

If you use the aws-sdk-v1 gem, you may also load the v2 Ruby SDK in the same process; The v2 Ruby SDK uses a different namespace, making this possible.

# when the v2 SDK ships, you will be able to do the following
gem 'aws-sdk', '~> 2.0'
gem 'aws-sdk-v1'

If you are currently using v1 of aws-sdk and you update to aws-sdk-v1, you may need to change how your require the Ruby SDK:

require 'aws-sdk-v1' # not 'aws-sdk'

If you are using a version of Ruby older than 1.9, you may encounter problems with Nokogiri. The authors dropped support for Ruby 1.8.x in Nokogiri 1.6. To use aws-sdk, you'll also have to install or specify a version of Nokogiri prior to 1.6, like this:

gem 'nokogiri', '~> 1.5.0'

You need to provide your AWS security credentials and choose a default region.

AWS.config(access_key_id: '...', secret_access_key: '...', region: 'us-west-2')

You can also specify these values via ENV:

export AWS_ACCESS_KEY_ID='...'
export AWS_SECRET_ACCESS_KEY='...'
export AWS_REGION='us-west-2'

Each service provides a service interface and a client.

ec2 = AWS.ec2 #=> AWS::EC2
ec2.client #=> AWS::EC2::Client

The client provides one method for each API operation. The client methods accept a hash of request params and return a response with a hash of response data. The service interfaces provide a higher level abstration built using the client.

Example: list instance tags using a client

resp = ec2.client.describe_tags(filters: [{ name: "resource-id", values: ["i-12345678"] }])
resp[:tag_set].first
#=> {:resource_id=>"i-12345678", :resource_type=>"instance", :key=>"role", :value=>"web"}

Example: list instance tags using the AWS::EC2 higher level interface

ec2.instances['i-12345678'].tags.to_h
#=> {"role"=>"web"}

See the API Documentation for more examples.

All HTTP requests to live services can be globally mocked (e.g. from within the spec_helper.rb file):

AWS.stub!
