@Generated(value="jsii-pacmak/1.84.0 (build 5404dcf)", date="2023-06-19T16:30:41.497Z") @Stability(Stable) public class CfnCustomResource extends CfnResource implements IInspectable
A CloudFormation AWS::CloudFormation::CustomResource.

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 .

Example:

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.cloudformation.*;
 CfnCustomResource cfnCustomResource = CfnCustomResource.Builder.create(this, "MyCfnCustomResource")
         .serviceToken("serviceToken")
         .build();
