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 assing 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

#s3_server_side_encryption ⇒ Symbol (readonly)
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 method:
You can construct an interface to Amazon S3 which always stores data using server side encryption as follows:
s3 = AWS::S3.new(:s3_server_side_encryption => :aes256)

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.

(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.
