class aws_cdk.core.ICfnResourceOptions(*args, **kwargs)

Bases: typing_extensions.Protocol

__init__(*args, **kwargs)



A condition to associate with this resource.

This means that only if the condition evaluates to ‘true’ when the stack is deployed, the resource will be included. This is provided to allow CDK projects to produce legacy templates, but noramlly there is no need to use it in CDK projects.

Return type



Associate the CreationPolicy attribute with a resource to prevent its status from reaching create complete until AWS CloudFormation receives a specified number of success signals or the timeout period is exceeded.

To signal a resource, you can use the cfn-signal helper script or SignalResource API. AWS CloudFormation publishes valid signals to the stack events so that you track the number of signals sent.

Return type



With the DeletionPolicy attribute you can preserve or (in some cases) backup a resource when its stack is deleted.

You specify a DeletionPolicy attribute for each resource that you want to control. If a resource has no DeletionPolicy attribute, AWS CloudFormation deletes the resource by default. Note that this capability also applies to update operations that lead to resources being removed.

Return type



Metadata associated with the CloudFormation resource.

This is not the same as the construct metadata which can be added using construct.addMetadata(), but would not appear in the CloudFormation template automatically.

Return type

Optional[Mapping[str, Any]]


Use the UpdatePolicy attribute to specify how AWS CloudFormation handles updates to the AWS::AutoScaling::AutoScalingGroup resource.

AWS CloudFormation invokes one of three update policies depending on the type of change you make or whether a scheduled action is associated with the Auto Scaling group.

Return type



Use the UpdateReplacePolicy attribute to retain or (in some cases) backup the existing physical instance of a resource when it is replaced during a stack update operation.
