Methods

add_deletion_override(path)

Syntactic sugar for addOverride(path, undefined).

Parameters

path (str) – The path of the value to delete.

Return type

None

add_depends_on(target)

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

Parameters

target (CfnResource) –

Return type

None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters
  • key (str) –

  • value (Any) –

See

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

Return type

None

add_override(path, value)

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with “Properties.” (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example:

cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"])
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")

would add the overrides Example:

"Properties": {
   "GlobalSecondaryIndexes": [
     {
       "Projection": {
         "NonKeyAttributes": [ "myattribute" ]
         ...
       }
       ...
     },
     {
       "ProjectionType": "INCLUDE"
       ...
     },
   ]
   ...
}
Parameters
  • path (str) –

    • The path of the property, you can use dot notation to override values in complex types. Any intermdediate keys will be created as needed.

  • value (Any) –

    • The value. Could be primitive or complex.

Return type

None

add_property_deletion_override(property_path)

Adds an override that deletes the value of a property from the resource definition.

Parameters

property_path (str) – The path to the property.

Return type

None

add_property_override(property_path, value)

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

Parameters
  • property_path (str) – The path of the property.

  • value (Any) – The value.

Return type

None

apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

Parameters
  • policy (Optional[RemovalPolicy]) –

  • apply_to_update_replace_policy (Optional[bool]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: true

  • default (Optional[RemovalPolicy]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resoure, please consult that specific resource’s documentation.

Return type

None

get_att(attribute_name)

ScheduledActionProperty

class CfnScalableTarget.ScheduledActionProperty(*, schedule, scheduled_action_name, end_time=None, scalable_target_action=None, start_time=None, timezone=None)

Bases: object

ScheduledAction is a property of the AWS::ApplicationAutoScaling::ScalableTarget resource that specifies a scheduled action for a scalable target.

For more information, see PutScheduledAction in the Application Auto Scaling API Reference . For more information about scheduled scaling, including the format for cron expressions, see Scheduled scaling in the Application Auto Scaling User Guide .

Parameters
  • schedule (str) – The schedule for this action. The following formats are supported:. - At expressions - ” at( *yyyy* - *mm* - *dd* T *hh* : *mm* : *ss* ) ” - Rate expressions - ” rate( *value* *unit* ) ” - Cron expressions - ” cron( *fields* ) ” At expressions are useful for one-time schedules. Cron expressions are useful for scheduled actions that run periodically at a specified date and time, and rate expressions are useful for scheduled actions that run at a regular interval. At and cron expressions use Universal Coordinated Time (UTC) by default. The cron format consists of six fields separated by white spaces: [Minutes] [Hours] [Day_of_Month] [Month] [Day_of_Week] [Year]. For rate expressions, value is a positive integer and unit is minute | minutes | hour | hours | day | days .

  • scheduled_action_name (str) – The name of the scheduled action. This name must be unique among all other scheduled actions on the specified scalable target.

  • end_time (Union[IResolvable, datetime, None]) – The date and time that the action is scheduled to end, in UTC.

  • scalable_target_action (Union[IResolvable, ScalableTargetActionProperty, None]) – The new minimum and maximum capacity. You can set both values or just one. At the scheduled time, if the current capacity is below the minimum capacity, Application Auto Scaling scales out to the minimum capacity. If the current capacity is above the maximum capacity, Application Auto Scaling scales in to the maximum capacity.

  • start_time (Union[IResolvable, datetime, None]) – The date and time that the action is scheduled to begin, in UTC.

  • timezone (Optional[str]) – The time zone used when referring to the date and time of a scheduled action, when the scheduled action uses an at or cron expression.

Union[IResolvable, datetime, None]

scalable_target_action

The new minimum and maximum capacity.

You can set both values or just one. At the scheduled time, if the current capacity is below the minimum capacity, Application Auto Scaling scales out to the minimum capacity. If the current capacity is above the maximum capacity, Application Auto Scaling scales in to the maximum capacity.

schedule

.

  • At expressions - ” at( *yyyy* - *mm* - *dd* T *hh* : *mm* : *ss* )

  • Rate expressions - ” rate( *value* *unit* )

  • Cron expressions - ” cron( *fields* )

At expressions are useful for one-time schedules. Cron expressions are useful for scheduled actions that run periodically at a specified date and time, and rate expressions are useful for scheduled actions that run at a regular interval.

At and cron expressions use Universal Coordinated Time (UTC) by default.

The cron format consists of six fields separated by white spaces: [Minutes] [Hours] [Day_of_Month] [Month] [Day_of_Week] [Year].

For rate expressions, value is a positive integer and unit is minute | minutes | hour | hours | day | days .

SuspendedStateProperty

class CfnScalableTarget.SuspendedStateProperty(*, dynamic_scaling_in_suspended=None, dynamic_scaling_out_suspended=None, scheduled_scaling_suspended=None)

Bases: object

SuspendedState is a property of the AWS::ApplicationAutoScaling::ScalableTarget resource that specifies whether the scaling activities for a scalable target are in a suspended state.

Parameters
  • dynamic_scaling_in_suspended (Union[bool, IResolvable, None]) – Whether scale in by a target tracking scaling policy or a step scaling policy is suspended. Set the value to true if you don’t want Application Auto Scaling to remove capacity when a scaling policy is triggered. The default is false .

  • dynamic_scaling_out_suspended (Union[bool, IResolvable, None]) – Whether scale out by a target tracking scaling policy or a step scaling policy is suspended. Set the value to true if you don’t want Application Auto Scaling to add capacity when a scaling policy is triggered. The default is false .

  • scheduled_scaling_suspended (Union[bool, IResolvable, None]) – Whether scheduled scaling is suspended. Set the value to true if you don’t want Application Auto Scaling to add or remove capacity by initiating scheduled actions. The default is false .
