Overview

A configuration object for AWS interfaces and clients.

Configuring Credentials

In order to do anything with AWS you will need to assign credentials. The simplest method is to assign your credentials into the default configuration:

AWS.config(:access_key_id => 'KEY', :secret_access_key => 'SECRET')

You can also export them into your environment and they will be picked up automatically:

export AWS_ACCESS_KEY_ID='YOUR_KEY_ID_HERE'
export AWS_SECRET_ACCESS_KEY='YOUR_SECRET_KEY_HERE'

For compatability with other AWS gems, the credentials can also be exported like:

export AMAZON_ACCESS_KEY_ID='YOUR_KEY_ID_HERE'
export AMAZON_SECRET_ACCESS_KEY='YOUR_SECRET_KEY_HERE'

Modifying a Configuration

Configuration objects are read-only. If you need a different set of configuration values, call #with, passing in the updates and a new configuration object will be returned.

config = Configuration.new(:max_retires => 3)
new_config = config.with(:max_retries => 2)

config.max_retries #=> 3
new_config.max_retries #=> 2

Global Configuration

The global default configuration can be found at AWS.config

    require 'logger'
AWS.config(:logger => Logger.new($stdout))
  • :log_level (Symbol) — default: :info —

    The level log messages are sent to the logger with (e.g. :notice, :info, :warn, :debug, etc).

  • :log_formatter (Object) —

    The log formatter is responsible for building log messages from responses. You can quickly change log formats by providing a pre-configured log formatter.

    AWS.config(:log_formatter => AWS::Core::LogFormatter.colored)

    Here is a list of pre-configured log formatters:

    • AWS::Core::LogFormatter.default

    • AWS::Core::LogFormatter.short

    • AWS::Core::LogFormatter.debug

    • AWS::Core::LogFormatter.colored

    You can also create an instance of AWS::Core::LogFormatter with a custom log message pattern. See LogFormatter for a complete list of pattern substitutions.

    pattern = "[AWS :operation :duration] :error_message"
AWS.config(:log_formatter => AWS::Core::LogFormatter.new(pattern))

    Lastly you can pass any object that responds to #format accepting and instance of Response and returns a string.

  • :max_retries (Integer) — default: 3 —

    The maximum number of times service errors (500) should be retried. There is an exponential backoff in between service request retries, so the more retries the longer it can take to fail.

  • :proxy_uri (String, URI, nil) — default: nil —

    The URI of the proxy to send service requests through. You can pass a URI object or a URI string:

    AWS.config(:proxy_uri => 'https://user:[email protected]:443/path?query')
  • :ops_works_endpoint (String) — default: 'opsworks.us-east-1.amazonaws.com' —

    The service endpoint for Amazon Route 53.

  • :s3_endpoint (String) — default: 's3.amazonaws.com' —

    The service endpoint for Amazon S3.

  • :s3_force_path_style (Boolean) — default: false —

    When true, requests will always use path style. This can be useful for testing environments.

  • :s3_multipart_max_parts (Integer) — default: 10000 —

    The maximum number of parts to split a file into when uploading in parts to S3.

  • :s3_multipart_threshold (Integer) — default: 16777216 —

    When uploading data to S3, if the number of bytes to send exceeds :s3_multipart_threshold then a multi part session is automatically started and the data is sent up in chunks. The size of each part is specified by :s3_multipart_min_part_size. Defaults to 16777216 (16MB).

  • :s3_multipart_min_part_size (Integer) — default: 5242880 —

    The absolute minimum size (in bytes) each S3 multipart segment should be. Defaults to 5242880 (5MB).

  • :s3_server_side_encryption (Symbol) — default: nil —

    The algorithm to use when encrypting object data on the server side. The only valid value is :aes256, which specifies that the object should be stored using the AES encryption algorithm with 256 bit keys. Defaults to nil, meaning server side encryption is not used unless specified on each individual call to upload an object. This option controls the default behavior for the following methods:

  • :s3_encryption_key (OpenSSL::PKey::RSA, String) — default: nil —

    If this is set, AWS::S3::S3Object #read and #write methods will always perform client-side encryption with this key. The key can be overridden at runtime by using the :encryption_key option. A value of nil means that client-side encryption will not be used.

  • :s3_encryption_materials_location (Symbol) — default: :metadata —

    When set to :instruction_file, AWS::S3::S3Object will store encryption materials in a separate object, instead of the object metadata.

  • :simple_db_endpoint (String) — default: 'sdb.amazonaws.com' —

    The service endpoint for Amazon SimpleDB.

  • :simple_db_consistent_reads (Boolean) — default: false —

    Determines if all SimpleDB read requests should be done consistently. Consistent reads are slower, but reflect all changes to SDB.

  • :simple_email_service_endpoint (String) — default: 'email.us-east-1.amazonaws.com' —

    The service endpoint for Amazon Simple Email Service.

  • :simple_workflow_endpoint (String) — default: 'swf.us-east-1.amazonaws.com' —

    The service endpoint for Amazon Simple Workflow Service.

  • :credential_provider (CredentialProviders::Provider) — default: AWS::Core::CredentialProviders::DefaultProvider.new —

    Returns the credential provider. The default credential provider attempts to check for statically assigned credentials, ENV credentials and credentials in the metadata service of EC2.

  • :ssl_ca_file (String) —

    The path to a CA cert bundle in PEM format.

    If :ssl_verify_peer is true (the default) this bundle will be used to validate the server certificate in each HTTPS request. The AWS SDK for Ruby ships with a CA cert bundle, which is the default value for this option.

  • :ssl_ca_path (String) — default: nil —

    The path the a CA cert directory.

  • :ssl_verify_peer (Boolean) — default: true —

    When true the HTTP handler validate server certificates for HTTPS requests.

    This option should only be disabled for diagnostic purposes; leaving this option set to false exposes your application to man-in-the-middle attacks and can pose a serious security risk.

  • :stub_requests (Boolean) — default: false —

    When true requests are not sent to AWS, instead empty responses are generated and returned to each service request.

  • :sns_endpoint (String) — default: 'sns.us-east-1.amazonaws.com' —

    The service endpoint for Amazon SNS.

  • :sqs_endpoint (String) — default: 'sqs.us-east-1.amazonaws.com' —

    The service endpoint for Amazon SQS.

  • :storage_gateway_endpoint (String) — default: 'storagegateway.us-east-1.amazonaws.com' —

    The service endpoint for AWS Storage Gateway.

  • :sts_endpoint (String) — default: 'sts.amazonaws.com' —

    The service endpoint for AWS Security Token Service.

  • :use_ssl (Boolean) — default: true —

    When true, all requests to AWS are sent using HTTPS instead vanilla HTTP.

  • :user_agent_prefix (String) — default: nil —

    A string prefix to append to all requests against AWS services. This should be set for clients and applications built ontop of the aws-sdk gem.
