Class CfnCustomResource
- All Implemented Interfaces:
IConstruct
,IDependable
,IInspectable
,software.amazon.jsii.JsiiSerializable
,software.constructs.IConstruct
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();
