to be refreshed and it is called with the AssumeRoleCredentials object.
‘before_refresh` is called when AWS credentials are required and need
that can be used to help manage refreshing tokens.
The AssumeRoleCredentials also provides a `before_refresh` callback
constructed.
If you omit `:client` option, a new {STS::Client} object will be
ec2 = Aws::EC2::Client.new(credentials: role_credentials)
)
role_session_name: “session-name”
role_arn: “linked::account::arn”,
client: Aws::STS::Client.new(…),
role_credentials = Aws::AssumeRoleCredentials.new(
a role via {Aws::STS::Client#assume_role}.
An auto-refreshing credential provider that works by assuming
