AWS SDK for Ruby Build Status

The official AWS SDK for Ruby.


You can install the AWS SDK for Ruby with rubygems:

gem install aws-sdk

If you are using Bundler, we recommend that you express a major version dependency (aws-sdk follows semantic versioning):

gem 'aws-sdk', '~> 1.0'

Basic Configuration

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_REGION='us-west-2'

Basic Usage

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"] }])
#=> {:resource_id=>"i-12345678", :resource_type=>"instance", :key=>"role", :value=>"web"}

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

#=> {"role"=>"web"}

See the API Documentation for more examples.
