CfnScheduledActionPropsMixin

class aws_cdk.mixins_preview.aws_autoscaling.mixins.CfnScheduledActionPropsMixin(props, *, strategy=None)

Bases: Mixin

The AWS::AutoScaling::ScheduledAction resource specifies an Amazon EC2 Auto Scaling scheduled action so that the Auto Scaling group can change the number of instances available for your application in response to predictable load changes.

When you update a stack with an Auto Scaling group and scheduled action, CloudFormation always sets the min size, max size, and desired capacity properties of your group to the values that are defined in the AWS::AutoScaling::AutoScalingGroup section of your template. However, you might not want CloudFormation to do that when you have a scheduled action in effect. You can use an UpdatePolicy attribute to prevent CloudFormation from changing the min size, max size, or desired capacity property values during a stack update unless you modified the individual values in your template. If you have rolling updates enabled, before you can update the Auto Scaling group, you must suspend scheduled actions by specifying an UpdatePolicy attribute for the Auto Scaling group. You can find a sample update policy for rolling updates in Configure Amazon EC2 Auto Scaling resources .

For more information, see Scheduled scaling and Suspending and resuming scaling processes in the Amazon EC2 Auto Scaling User Guide .

cfn_scheduled_action_props_mixin = autoscaling_mixins.CfnScheduledActionPropsMixin(autoscaling_mixins.CfnScheduledActionMixinProps(
    auto_scaling_group_name="autoScalingGroupName",
    desired_capacity=123,

Create a mixin to apply properties to AWS::AutoScaling::ScheduledAction.

Parameters:

props (Union[CfnScheduledActionMixinProps, Dict[str, Any]]) – L1 properties to apply.
strategy (Optional[PropertyMergeStrategy]) – (experimental) Strategy for merging nested properties. Default: - PropertyMergeStrategy.MERGE
