Constructor Details

#initialize(options = {}) ⇒ Real

Initialize connection to STS

Notes

options parameter must include values for :aws_access_key_id and :aws_secret_access_key in order to create a connection

Examples

iam = STS.new( :aws_access_key_id => your_aws_access_key_id, :aws_secret_access_key => your_aws_secret_access_key )

Parameters

  • options<~Hash> - config arguments for connection. Defaults to {}.

Returns

  • STS object with connection to AWS.
