You can configure your AWS credentials a few different ways: * Call AWS.config with :access_key_id and :secret_access_key * Export AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY to ENV * On EC2 you can run instances with an IAM instance profile and credentials will be auto loaded from the instance metadata service on those instances. * Call AWS.config with :credential_provider. A credential provider should either include AWS::Core::CredentialProviders::Provider or respond to the same public methods. = Ruby on Rails In a Ruby on Rails application you may also specify your credentials in the following ways: * Via a config initializer script using any of the methods mentioned above (e.g. RAILS_ROOT/config/initializers/aws-sdk.rb). * Via a yaml configuration file located at RAILS_ROOT/config/aws.yml.
