:credential_provider => AWS::Core::CredentialProviders::SharedCredentialFile

Provider.new)

Creating the provider object with the default constructor specifies the credentials file's default profile.

You can also use the constructor's profile_name option to specify a profile by name or its path option

to specify a nondefault credentials file location.

• You can specify a credential provider that will be used by all service clients by passing a provider object

to the AWS.config method. The following example specifies the default profile from the credentials file

for all services.

AWS.config(

:credential_provider => AWS::Core::CredentialProviders::SharedCredentialFile

Provider.new)

# Create a new S3 object

s3 = AWS::S3.new

You can then use the Amazon S3 client object's default constructor, which automatically loads the ap-

propriate profile.

For the full list of SDK for Ruby credential provider classes, see AWS::Core::CredentialProviders. In the

SDK for Ruby, all provider classes mix in the Provider interface.

Tip

You can also use this approach to supply your own credentials provider. Just implement a cre-

dentials provider class that mixes in the Provider interface.You can then pass an instance of

the class to a service's client class constructor or to AWS.config, as described above.

Explicitly Specifying Credentials

You can specify credentials explicitly as follows.

• Specify credentials for a particular service by using the client class constructor's :access_key_id

and :secret_access_key options.

The following example specifies an explicit set of credentials for the Amazon S3 client object.

s3 = AWS::S3.new(

:access_key_id => 'AKIAIOSFODNN7EXAMPLE',

:secret_access_key => 'wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY')

• Specify credentials for every service by using the AWS.config method's :access_key_id and

:secret_access_key options.

The following example specifies an explicit set of credentials for every service, so you can use the default

constructor to create the Amazon S3 client object. It will automatically use the credentials that you

passed to AWS.config.

AWS.config(

:access_key_id => 'AKIAIOSFODNN7EXAMPLE',

:secret_access_key => 'wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY')
