Defined in:
lib/aws-sdk-core/assume_role_credentials.rb

Overview

An auto-refreshing credential provider that works by assuming a role via STS::Client#assume_role.

role_credentials = Aws::AssumeRoleCredentials.new(
  client: Aws::STS::Client.new(...),
  role_arn: "linked::account::arn",
  role_session_name: "session-name"
)

ec2 = Aws::EC2::Client.new(credentials: role_credentials)

If you omit ‘:client` option, a new STS::Client object will be constructed.
