SignalsOptions

class aws_cdk.aws_autoscaling.SignalsOptions(*, min_success_percentage=None, timeout=None)

Bases: object

Customization options for Signal handling.

Parameters

min_success_percentage (Union[int, float, None]) – The percentage of signals that need to be successful. If this number is less than 100, a percentage of signals may be failure signals while still succeeding the creation or update in CloudFormation. Default: 100
timeout (Optional[Duration]) – How long to wait for the signals to be sent. This should reflect how long it takes your instances to start up (including instance start time and instance initialization time). Default: Duration.minutes(5)

        ec2.InitFile.from_string("/etc/my_instance", "This got written during instance startup")),
    signals=autoscaling.Signals.wait_for_all(
        timeout=Duration.minutes(10)
