CustomResourceProps

class aws_cdk.aws_cloudformation.CustomResourceProps(*, provider, properties=None, removal_policy=None, resource_type=None)

Bases: object

(deprecated) Properties to provide a Lambda-backed custom resource.

Parameters:

provider (ICustomResourceProvider) – (deprecated) The provider which implements the custom resource. You can implement a provider by listening to raw AWS CloudFormation events through an SNS topic or an AWS Lambda function or use the CDK’s custom resource provider framework which makes it easier to implement robust providers:: import * as custom_resources from ‘@aws-cdk/custom-resources’; import * as lambda from ‘@aws-cdk/aws-lambda’; import { Stack } from ‘@aws-cdk/core’; declare const myOnEventLambda: lambda.Function; declare const myIsCompleteLambda: lambda.Function; const stack = new Stack(); const provider = new custom_resources.Provider(stack, ‘myProvider’, { onEventHandler: myOnEventLambda, isCompleteHandler: myIsCompleteLambda, // optional }); Example:: import * as cloudformation from ‘@aws-cdk/aws-cloudformation’; import * as lambda from ‘@aws-cdk/aws-lambda’; declare const myFunction: lambda.Function; // invoke an AWS Lambda function when a lifecycle event occurs: const provider = cloudformation.CustomResourceProvider.fromLambda(myFunction); Example:: import * as cloudformation from ‘@aws-cdk/aws-cloudformation’; import * as sns from ‘@aws-cdk/aws-sns’; declare const myTopic: sns.Topic; // publish lifecycle events to an SNS topic: const provider = cloudformation.CustomResourceProvider.fromTopic(myTopic);
properties (Optional[Mapping[str, Any]]) – (deprecated) Properties to pass to the Lambda. Default: - No properties.
removal_policy (Optional[RemovalPolicy]) – (deprecated) The policy to apply when this resource is removed from the application. Default: cdk.RemovalPolicy.Destroy
resource_type (Optional[str]) – (deprecated) For custom resources, you can specify AWS::CloudFormation::CustomResource (the default) as the resource type, or you can specify your own resource type name. For example, you can use “Custom::MyCustomResourceTypeName”. Custom resource type names must begin with “Custom::” and can include alphanumeric characters and the following characters: _@-. You can specify a custom resource type name up to a maximum length of 60 characters. You cannot change the type during an update. Using your own resource type names helps you quickly differentiate the types of custom resources in your stack. For example, if you had two custom resources that conduct two different ping tests, you could name their type as Custom::PingTester to make them easily identifiable as ping testers (instead of using AWS::CloudFormation::CustomResource). Default: - AWS::CloudFormation::CustomResource

provider

(deprecated) The provider which implements the custom resource.

You can implement a provider by listening to raw AWS CloudFormation events through an SNS topic or an AWS Lambda function or use the CDK’s custom resource provider framework which makes it easier to implement robust providers:

import aws_cdk.custom_resources as custom_resources
import aws_cdk.aws_lambda as lambda_
from aws_cdk.core import Stack
# my_on_event_lambda: lambda.Function
# my_is_complete_lambda: lambda.Function
stack = Stack()

provider = custom_resources.Provider(stack, "myProvider",
    on_event_handler=my_on_event_lambda,
    is_complete_handler=my_is_complete_lambda
)

Example:

import aws_cdk.aws_cloudformation as cloudformation
import aws_cdk.aws_lambda as lambda_
# my_function: lambda.Function

# invoke an AWS Lambda function when a lifecycle event occurs:
provider = cloudformation.CustomResourceProvider.from_lambda(my_function)

Example:

import aws_cdk.aws_cloudformation as cloudformation
import aws_cdk.aws_sns as sns
# my_topic: sns.Topic

# publish lifecycle events to an SNS topic:
provider = cloudformation.CustomResourceProvider.from_topic(my_topic)

(deprecated) For custom resources, you can specify AWS::CloudFormation::CustomResource (the default) as the resource type, or you can specify your own resource type name.
