This is version 2 of the aws-sdk
gem. Version 1 can be found in the
aws-sdk-v1 branch.
If you receive this error, you likely have upgraded to version 2 of the
aws-sdk
gem unintentionally. Version 2 uses the Aws
namespace, not AWS
.
This allows version 1 and version 2 to be used in the same application.
The AWS SDK for Ruby is available as the aws-sdk
gem from RubyGems.
To install,
gem install aws-sdk
Please use a major version when expressing a dependency on aws-sdk
.
gem 'aws-sdk', '~> 2'
Please use these community resources for getting help. We use the GitHub issues for tracking bugs and feature requests and have limited bandwidth to address them.
- Ask a question on StackOverflow and tag it with
aws-sdk-ruby
- Come join the AWS SDK for Ruby Gitter Channel
- Open a support ticket with AWS Support, if it turns out that you may have found a bug, please open an issue
- If in doubt as to whether your issue is a question about how to use AWS or a potential SDK issue, feel free to open a GitHub issue on this repo.
If you encounter a bug with aws-sdk-ruby
we would like to hear about it. Search the existing issues and try to make sure your problem doesn’t already exist before opening a new issue. It’s helpful if you include the version of aws-sdk-ruby
, ruby version and OS you’re using. Please include a stack trace and reduced repro case when appropriate, too.
The GitHub issues are intended for bug reports and feature requests. For help and questions with using aws-sdk-ruby
please make use of the resources listed in the Getting Help section.
FEATURE_REQUEST.md
in particular is a good way to signal your interest in a feature or issue. There are limited resources available for handling issues and by keeping the list of open issues lean we can respond in a timely manner.
You need to configure :credentials
and a :region
to make API calls. It is recommended that you provide these via your environment. This makes it easier to rotate credentials and it keeps your secrets out of source control.
The SDK searches the following locations for credentials:
ENV['AWS_ACCESS_KEY_ID']
andENV['AWS_SECRET_ACCESS_KEY']
- Unless
ENV['AWS_SDK_CONFIG_OPT_OUT']
is set, the shared configuration files (~/.aws/credentials
and~/.aws/config
) will be checked for arole_arn
andsource_profile
, which if present will be used to attempt to assume a role. - The shared credentials ini file at
~/.aws/credentials
(more information)- Unless
ENV['AWS_SDK_CONFIG_OPT_OUT']
is set, the shared configuration ini file at~/.aws/config
will also be parsed for credentials.
- Unless
- From an instance profile when running on EC2, or from the ECS credential provider when running in an ECS container with that feature enabled.
The SDK searches the following locations for a region:
ENV['AWS_REGION']
- Unless
ENV['AWS_SDK_CONFIG_OPT_OUT']
is set, the shared configuration files (~/.aws/credentials
and~/.aws/config
) will also be checked for a region selection.
The region is used to construct an SSL endpoint. If you need to connect to a non-standard endpoint, you may specify the :endpoint
option.
You can configure default credentials and region via Aws.config
. In version 2, Aws.config
is a vanilla Ruby hash, not a method like it was in version 1. The Aws.config
hash takes precedence over environment variables.
require 'aws-sdk'
Aws.config.update({
region: 'us-west-2',
credentials: Aws::Credentials.new('akid', 'secret')
})
Valid region and credentials options are:
:region
- A string likeus-west-2
. See this document for a list of supported regions by service.:credentials
- An instance of one of the following classes:
You may also pass configuration options directly to resource and client constructors. These options take precedence over the environment and Aws.config
defaults.
# resource constructors
ec2 = Aws::EC2::Resource.new(region:'us-west-2', credentials: credentials)
# client constructors
ec2 = Aws::EC2::Client.new(region:'us-west-2', credentials: credentials)
Please take care to never commit credentials to source control. We strongly recommended loading credentials from an external source.
require 'aws-sdk'
require 'json'
creds = JSON.load(File.read('secrets.json'))
Aws.config[:credentials] = Aws::Credentials.new(creds['AccessKeyId'], creds['SecretAccessKey'])
Construct a service client to make API calls. Each client provides a 1-to-1 mapping of methods to API operations. Refer to the API documentation for a complete list of available methods.
# list buckets in Amazon S3
s3 = Aws::S3::Client.new
resp = s3.list_buckets
resp.buckets.map(&:name)
#=> ["bucket-1", "bucket-2", ...]
API methods accept a hash of additional request parameters and return structured response data.
# list the first two objects in a bucket
resp = s3.list_objects(bucket: 'aws-sdk-core', max_keys: 2)
resp.contents.each do |object|
puts "#{object.key} => #{object.etag}"
end
Many AWS operations limit the number of results returned with each response. To make it easy to get the next page of results, every AWS response object is enumerable:
# yields one response object per API call made, this will enumerate
# EVERY object in the named bucket
s3.list_objects(bucket:'aws-sdk').each do |response|
puts response.contents.map(&:key)
end
If you prefer to control paging yourself, response objects have helper methods that control paging:
# make a request that returns a truncated response
resp = s3.list_objects(bucket:'aws-sdk')
resp.last_page? #=> false
resp.next_page? #=> true
resp = resp.next_page # send a request for the next response page
resp = resp.next_page until resp.last_page?
Waiters are utility methods that poll for a particular state. To invoke a
waiter, call #wait_until
on a client:
begin
ec2.wait_until(:instance_running, instance_ids:['i-12345678'])
puts "instance running"
rescue Aws::Waiters::Errors::WaiterFailed => error
puts "failed waiting for instance running: #{error.message}"
end
Waiters have sensible default polling intervals and maximum attempts. You can
configure these per call to #wait_until
. You can also register callbacks
that are triggered before each polling attempt and before waiting.
See the API documentation for more examples and for a list of supported
waiters per service.
Resource interfaces are object oriented classes that represent actual resources in AWS. Resource interfaces built on top of API clients and provide additional functionality.
s3 = Aws::S3::Resource.new
# reference an existing bucket by name
bucket = s3.bucket('aws-sdk')
# enumerate every object in a bucket
bucket.objects.each do |obj|
puts "#{obj.key} => #{obj.etag}"
end
# batch operations, delete objects in batches of 1k
bucket.objects(prefix: '/tmp-files/').delete
# single object operations
obj = bucket.object('hello')
obj.put(body:'Hello World!')
obj.etag
obj.delete
The aws-sdk-core
gem ships with a REPL that provides a simple way to test
the Ruby SDK. You can access the REPL by running aws.rb
from the command line.
$ aws.rb
Aws> ec2.describe_instances.reservations.first.instances.first
[Aws::EC2::Client 200 0.216615 0 retries] describe_instances()
<struct
instance_id="i-1234567",
image_id="ami-7654321",
state=<struct code=16, name="running">,
...>
You can enable HTTP wire logging by setting the verbose flag:
$ aws.rb -v
In the REPL, every service class has a helper that returns a new client object. Simply downcase the service module name for the helper:
Aws::S3
=>s3
Aws::EC2
=>ec2
- etc
This project uses semantic versioning. You can safely express a dependency on a major version and expect all minor and patch versions to be backwards compatible.
