CfnDeletionPolicy

class aws_cdk.core.CfnDeletionPolicy

Bases: enum.Enum

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.

Attributes

DELETE

AWS CloudFormation deletes the resource and all its content if applicable during stack deletion.

You can add this deletion policy to any resource type. By default, if you don’t specify a DeletionPolicy, AWS CloudFormation deletes your resources. However, be aware of the following considerations:

RETAIN

AWS CloudFormation keeps the resource without deleting the resource or its contents when its stack is deleted. You can add this deletion policy to any resource type. Note that when AWS CloudFormation completes the stack deletion, the stack will be in Delete_Complete state; however, resources that are retained continue to exist and continue to incur applicable charges until you delete those resources.

SNAPSHOT

For resources that support snapshots (AWS::EC2::Volume, AWS::ElastiCache::CacheCluster, AWS::ElastiCache::ReplicationGroup, AWS::RDS::DBInstance, AWS::RDS::DBCluster, and AWS::Redshift::Cluster), AWS CloudFormation creates a snapshot for the resource before deleting it.

Note that when AWS CloudFormation completes the stack deletion, the stack will be in the Delete_Complete state; however, the snapshots that are created with this policy continue to exist and continue to incur applicable charges until you delete those snapshots.

Attributes
