Pulumi CDK Adapter (preview)

The Pulumi CDK Adapter is a library that enables Pulumi programs to use AWS CDK constructs.

The adapter allows writing AWS CDK code as part of an AWS CDK Stack inside a Pulumi program, and having the resulting AWS resources be deployed and managed via Pulumi. Outputs of resources defined in a Pulumi program can be passed into AWS CDK Constructs, and outputs from AWS CDK stacks can be used as inputs to other Pulumi resources.

Note: Currently, the Pulumi CDK Adapter preview is available only for TypeScript/JavaScript users.

For example, to construct an AWS AppRunner Service resource from within a Pulumi program, and export the resulting service's URL as as Pulumi Stack Output you write the following:

import * as pulumi from '@pulumi/pulumi';
import * as pulumicdk from '@pulumi/cdk';
import { Service, Source } from '@aws-cdk/aws-apprunner-alpha';

class AppRunnerStack extends pulumicdk.Stack {
    url: pulumi.Output<string>;

    constructor(id: string, options?: pulumicdk.StackOptions) {
        super(id, options);

        const service = new Service(this, 'service', {
            source: Source.fromEcrPublic({
                imageConfiguration: { port: 8000 },
                imageIdentifier: 'public.ecr.aws/aws-containers/hello-app-runner:latest',
            }),
        });

        this.url = this.asOutput(service.serviceUrl);
    }
}

const app = new pulumicdk.App('app', (scope: pulumicdk.App): pulumicdk.AppOutputs => {
    const stack = new AppRunnerStack('teststack');
    return {
        url: stack.url,
    };
});
export const url = app.outputs['url'];

And then deploy with pulumi update:

> pulumi up

Bootstrapping

CDK has the concept of bootstrapping which requires you to first bootstrap your account with certain AWS resources that CDK needs to exist. With Pulumi CDK this is not required! Pulumi CDK will automatically and dynamically create the bootstrap resources as needed.

S3 Resources

When any file assets are added to your application, CDK will automatically create the following staging resources.

1. aws.s3.BucketV2

• forceDestroy: true

2. aws.s3.BucketServerSideEncryptionConfigurationV2

• AES256

3. aws.s3.BucketVersioningV2

• Enabled

4. aws.s3.BucketLifecycleConfigurationV2

• Expire old versions > 365 days
• Expire deploy-time assets > 30 days

5. aws.s3.BucketPolicy

• Require SSL

API

App

A Pulumi CDK App component. This is the entrypoint to your Pulumi CDK application. In order to deploy a CDK application with Pulumi, you must start with this class.

constructor

Create and register an AWS CDK app deployed with Pulumi.

constructor(id: string, createFunc: (scope: App) => void | AppOutputs, props?: AppResourceOptions)

Parameters:

• id: The unique name of the app
• createFunc: A callback function where all CDK Stacks must be created
• options: A bag of options that control the resource's behavior

outputs

The collection of outputs from the Pulumi CDK App represented as Pulumi Outputs. Each CfnOutput defined in each AWS CDK Stack will populate a value in the outputs.

outputs: { [outputId: string]: pulumi.Output<any> }

AppResourceOptions

Options specific to the App Component

interface AppResourceOptions

remapCloudControlResource

This optional method can be implemented to define a mapping to override and/or provide an implementation for a CloudFormation resource type that is not (yet) implemented in the AWS Cloud Control API (and thus not yet available in the Pulumi AWS Native provider). Pulumi code can override this method to provide a custom mapping of CloudFormation elements and their properties into Pulumi CustomResources, commonly by using the AWS Classic provider to implement the missing resource.

remapCloudControlResource(logicalId: string, typeName: string, props: any, options: pulumi.ResourceOptions): ResourceMapping | undefined;

Parameters:

• logicalId: The logical ID of the resource being mapped.
• typeName: The CloudFormation type name of the resource being mapped.
• props: The bag of input properties to the CloudFormation resource being mapped.
• options: The set of Pulumi ResourceOptions to apply to the resource being mapped.

Returns an object containing one or more logical IDs mapped to Pulumi resources that must be created to implement the mapped CloudFormation resource, or else undefined if no mapping is implemented.

appId

This is a unique identifier for the application. It will be used in the names of the staging resources created for the application. This appId should be unique across apps.

Stack

A Construct that represents an AWS CDK stack deployed with Pulumi. In order to deploy a CDK stack with Pulumi, it must derive from this class.

constructor

Create and register an AWS CDK stack deployed with Pulumi.

constructor(app: App, name: string, options?: StackOptions)

Parameters:

• app: The Pulumi CDK App
• name: The unique name of the resource.
• options: A bag of options that control this resource's behavior.

asOutput

Convert a CDK value to a Pulumi output.

Parameters:

• v: A CDK value.

asOutput<T>(v: T): pulumi.Output<T>

StackOptions

Options specific to the Stack component.

interface StackOptions

asString

Convert a Pulumi Output to a CDK string value.

function asString<T>(o: pulumi.Output<T>): string

Parameters:

• o: A Pulumi Output value which represents a string.

Returns A CDK token representing a string value.

asNumber

Convert a Pulumi Output to a CDK number value.

function asNumber<T>(o: pulumi.Output<T>): number

Parameters:

• o: A Pulumi Output value which represents a number.

Returns A CDK token representing a number value.

asList

Convert a Pulumi Output to a list of CDK values.

function asList<T>(o: pulumi.Output<T>): string[]

Parameters:

• o: A Pulumi Output value which represents a list.

Returns a CDK token representing a list of values.
