All Implemented Interfaces:

@Generated(value="jsii-pacmak/1.101.0 (build b95fe5d)", date="2024-07-12T19:33:56.223Z") @Stability(Stable) public class CfnCustomResource extends CfnResource implements IInspectable
In a CloudFormation template, you use the AWS::CloudFormation::CustomResource or Custom:: *String* resource type to specify custom resources.

Custom resources provide a way for you to write custom provisioning logic in CloudFormation template and have CloudFormation run it during a stack operation, such as when you create, update or delete a stack. For more information, see Custom resources .

If you use the VPC endpoints feature, custom resources in the VPC must have access to CloudFormation -specific Amazon Simple Storage Service ( Amazon S3 ) buckets. Custom resources must send responses to a presigned Amazon S3 URL. If they can't send responses to Amazon S3 , CloudFormation won't receive a response and the stack operation fails. For more information, see Setting up VPC endpoints for AWS CloudFormation .


 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
