.config(options = {}) ⇒ `Core::Configuration`

Note:

Changing the global configuration does not affect objects that have already been constructed.

The global configuration for AWS. Generally you set your prefered configuration operations once after loading the aws-sdk gem.

AWS.config({
  :access_key_id => 'ACCESS_KEY_ID',
  :secret_access_key => 'SECRET_ACCESS_KEY',
  :simple_db_endpoint => 'sdb.us-west-1.amazonaws.com',
  :max_retries => 2,
})

When using AWS classes they will always default to use configuration values defined in config.

AWS.config(:max_retries => 2)

sqs = AWS::SQS.new
sqs.config.max_retries #=> 2

If you want to change a configuration value for a single instance you pass the new configuration value to that object’s initializer:

AWS::SQS.new(:max_retries => 0)

Parameters:

options (Hash) (defaults to: {})

Options Hash (options):

:access_key_id (String) —

AWS access key id credential.
:secret_access_key (String) —

AWS secret access key credential.
:session_token (String, nil) —

AWS secret token credential.
:auto_scaling_endpoint (String) — default: 'autoscaling.us-east-1.amazonaws.com' —

The service endpoint for Auto Scaling.
:cloud_formation_endpoint (String) — default: 'cloudformation.us-east-1.amazonaws.com' —

The service endpoint for AWS CloudFormation.
:dynamo_db_endpoint (String) — default: 'dynamodb.amazonaws.com' —

The service endpoint for Amazon DynamoDB.
:dynamo_db_retry_throughput_errors (String) — default: true —

When true, AWS::DynamoDB::Errors::ProvisionedThroughputExceededException errors will be retried.
:ec2_endpoint (String) — default: 'ec2.amazonaws.com' —

The service endpoint for Amazon EC2.
:elb_endpoint (String) — default: 'elasticloadbalancing.us-east-1.amazonaws.com' —

The service endpoint for Elastic Load Balancing.
:http_handler (Object) — default: AWS::Core::Http::NetHttpHandler —

The http handler that sends requests to AWS.
:http_idle_timeout (Integer) — default: 60 —

The number of seconds a persistent connection is allowed to sit idle before it should no longer be used.
:http_open_timeout (Integer) — default: 15 —

The number of seconds before the :http_handler should timeout while trying to open a new HTTP sesssion.
:http_read_timeout (Integer) — default: 60 —

The number of seconds before the :http_handler should timeout while waiting for a HTTP response.
:http_wire_trace (Boolean) — default: false —

When true, the http handler will log all wire traces to the :logger. If a :logger is not configured, then wire traces will be sent to standard out.
:iam_endpoint (String) — default: 'iam.amazonaws.com' —

The service endpoint for AWS Idenity Access Management (IAM).
:logger (Logger, nil) — default: nil —
A logger to send log messages to. Here is an example that logs to standard out.
```
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 AWS::Core::LogFormatter for a complete list of pattern substituions.
```
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 AWS::Core::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')
```
:s3_endpoint (String) — default: 's3.amazonaws.com' —

The service endpoint for Amazon S3.
:s3_multipart_max_parts (Integer) — default: 1000 —

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 exceedes :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:
: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_service (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 reponses 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.
: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 requets against AWS services. This should be set for clients and applications built ontop of the aws-sdk gem.

Returns:

(Core::Configuration) —

Returns the new configuration.

Note:

Memoization is currently only supported for the EC2 APIs; other APIs are unaffected by the status of memoization. To protect your code from future changes in memoization support, you should not enable memoization while calling non-EC2 APIs.

Enables memoization for the current thread, within a block. Memoization lets you avoid making multiple requests for the same data by reusing the responses which have already been received. For example, consider the following code to get the most recently launched EC2 instance:

latest = ec2.instances.sort_by(&:launch_time).last

The above code would make N+1 requests (where N is the number of instances in the account); iterating the collection of instances is one request, and Enumerable#sort_by calls AWS::EC2::Instance#launch_time for each instance, causing another request per instance. We can rewrite the code as follows to make only one request:

latest = AWS.memoize do
  ec2.instances.sort_by(&:launch_time).last
end

Iterating the collection still causes a request, but each subsequent call to AWS::EC2::Instance#launch_time uses the results from that first request rather than making a new request for the same data.

While memoization is enabled, every response that is received from the service is retained in memory. Therefore you should use memoization only for short-lived blocks of code that make relatively small numbers of requests. The cached responses are used in two ways while memoization is enabled:

Before making a request, the SDK checks the cache for a response to a request with the same signature (credentials, service endpoint, operation name, and parameters). If such a response is found, it is used instead of making a new request.
Before retrieving data for an attribute of a resource (e.g. AWS::EC2::Instance#launch_time), the SDK attempts to find a cached response that contains the requested data. If such a response is found, the cached data is returned instead of making a new request.

When memoization is disabled, all previously cached responses are discarded.
