CfnResourceAutoScalingCreationPolicy

class aws_cdk.core.CfnResourceAutoScalingCreationPolicy(*, min_successful_instances_percent=None)

Bases: object

For an Auto Scaling group replacement update, specifies how many instances must signal success for the update to succeed.

Parameters

min_successful_instances_percent (Union[int, float, None]) – Specifies the percentage of instances in an Auto Scaling replacement update that must signal success for the update to succeed. You can specify a value from 0 to 100. AWS CloudFormation rounds to the nearest tenth of a percent. For example, if you update five instances with a minimum successful percentage of 50, three instances must signal success. If an instance doesn’t send a signal within the time specified by the Timeout property, AWS CloudFormation assumes that the instance wasn’t created.

Example:

# The code below shows an example of how to instantiate this type.
# The values are placeholders you should change.
