TrafficShiftConfig

class aws_cdk.aws_ecs.TrafficShiftConfig(*, step_bake_time=None, step_percent=None)

Bases: object

Configuration for traffic shift during progressive deployments.

Parameters:

step_bake_time (Optional[Duration]) – The duration to wait between traffic shifting steps. Valid values are 0 to 1440 minutes (24 hours). Default: - Duration.minutes(6) for linear, Duration.minutes(10) for canary
step_percent (Union[int, float, None]) – The percentage of production traffic to shift in each step. - For linear deployment: multiples of 0.1 from 3.0 to 100.0 - For canary deployment: multiples of 0.1 from 0.1 to 100.0 Default: - 10.0 for linear, 5.0 for canary
