AWS Service Catalog Construct Library
The APIs of higher level constructs in this module are in developer preview before they become stable. We will only make breaking changes to address unforeseen API issues. Therefore, these APIs are not subject to Semantic Versioning, and breaking changes will be announced in release notes. This means that while you may use them, you may need to update your source code when upgrading to a newer version of this package.
AWS Service Catalog enables organizations to create and manage catalogs of products for their end users that are approved for use on AWS.
Table Of Contents
The @aws-cdk/aws-servicecatalog package contains resources that enable users to automate governance and management of their AWS resources at scale.
import * as servicecatalog from '@aws-cdk/aws-servicecatalog-alpha';Portfolio
AWS Service Catalog portfolios allow administrators to organize, manage, and distribute cloud resources for their end users.
Using the CDK, a new portfolio can be created with the Portfolio construct:
new servicecatalog.Portfolio(this, 'Portfolio', {
displayName: 'MyPortfolio',
providerName: 'MyTeam',
});You can also specify optional metadata properties such as description and messageLanguage
to help better catalog and manage your portfolios.
new servicecatalog.Portfolio(this, 'Portfolio', {
displayName: 'MyFirstPortfolio',
providerName: 'SCAdmin',
description: 'Portfolio for a project',
messageLanguage: servicecatalog.MessageLanguage.EN,
});Read more at Creating and Managing Portfolios.
To reference an existing portfolio into your CDK application, use the Portfolio.fromPortfolioArn() factory method:
const portfolio = servicecatalog.Portfolio.fromPortfolioArn(this, 'ReferencedPortfolio',
'arn:aws:catalog:region:account-id:portfolio/port-abcdefghi');Granting access to a portfolio
You can grant access to and manage the IAM users, groups, or roles that have access to the products within a portfolio.
Entities with granted access will be able to utilize the portfolios resources and products via the console or AWS CLI.
Once resources are deployed end users will be able to access them via the console or service catalog CLI.
import * as iam from 'aws-cdk-lib/aws-iam';
declare const portfolio: servicecatalog.Portfolio;
const user = new iam.User(this, 'User');
portfolio.giveAccessToUser(user);
const role = new iam.Role(this, 'Role', {
assumedBy: new iam.AccountRootPrincipal(),
});
portfolio.giveAccessToRole(role);
const group = new iam.Group(this, 'Group');
portfolio.giveAccessToGroup(group);Sharing a portfolio with another AWS account
You can use account-to-account sharing to distribute a reference to your portfolio to other AWS accounts by passing the recipient account number. After the share is initiated, the recipient account can accept the share via CLI or console by importing the portfolio ID. Changes made to the shared portfolio will automatically propagate to recipients.
declare const portfolio: servicecatalog.Portfolio;
portfolio.shareWithAccount('012345678901');Product
Products are version friendly infrastructure-as-code templates that admins create and add to portfolios for end users to provision and create AWS resources.
Service Catalog supports products from AWS Marketplace or ones defined by a CloudFormation template.
The CDK currently only supports adding products of type CloudFormation.
Using the CDK, a new Product can be created with the CloudFormationProduct construct.
You can use CloudFormationTemplate.fromUrl to create a Product from a CloudFormation template directly from a URL that points to the template in S3, GitHub, or CodeCommit:
const product = new servicecatalog.CloudFormationProduct(this, 'MyFirstProduct', {
productName: "My Product",
owner: "Product Owner",
productVersions: [
{
productVersionName: "v1",
cloudFormationTemplate: servicecatalog.CloudFormationTemplate.fromUrl(
'https://raw.githubusercontent.com/awslabs/aws-cloudformation-templates/master/aws/services/ServiceCatalog/Product.yaml'),
},
],
});Creating a product from a local asset
A CloudFormationProduct can also be created by using a CloudFormation template held locally on disk using Assets.
Assets are files that are uploaded to an S3 Bucket before deployment.
CloudFormationTemplate.fromAsset can be utilized to create a Product by passing the path to a local template file on your disk:
import * as path from 'path';
const product = new servicecatalog.CloudFormationProduct(this, 'Product', {
productName: "My Product",
owner: "Product Owner",
productVersions: [
{
productVersionName: "v1",
cloudFormationTemplate: servicecatalog.CloudFormationTemplate.fromUrl(
'https://raw.githubusercontent.com/awslabs/aws-cloudformation-templates/master/aws/services/ServiceCatalog/Product.yaml'),
},
{
productVersionName: "v2",
cloudFormationTemplate: servicecatalog.CloudFormationTemplate.fromAsset(path.join(__dirname, 'development-environment.template.json')),
},
],
});Creating a product from a stack
You can create a Service Catalog CloudFormationProduct entirely defined with CDK code using a service catalog ProductStack.
A separate child stack for your product is created and you can add resources like you would for any other CDK stack,
such as an S3 Bucket, IAM roles, and EC2 instances. This stack is passed in as a product version to your
product. This will not create a separate CloudFormation stack during deployment.
import * as s3 from 'aws-cdk-lib/aws-s3';
import * as cdk from 'aws-cdk-lib';
class S3BucketProduct extends servicecatalog.ProductStack {
constructor(scope: Construct, id: string) {
super(scope, id);
new s3.Bucket(this, 'BucketProduct');
}
}
const product = new servicecatalog.CloudFormationProduct(this, 'Product', {
productName: "My Product",
owner: "Product Owner",
productVersions: [
{
productVersionName: "v1",
cloudFormationTemplate: servicecatalog.CloudFormationTemplate.fromProductStack(new S3BucketProduct(this, 'S3BucketProduct')),
},
],
});Adding a product to a portfolio
You add products to a portfolio to organize and distribute your catalog at scale. Adding a product to a portfolio creates an association, and the product will become visible within the portfolio side in both the Service Catalog console and AWS CLI. You can add a product to multiple portfolios depending on your organizational structure and how you would like to group access to products.
declare const portfolio: servicecatalog.Portfolio;
declare const product: servicecatalog.CloudFormationProduct;
portfolio.addProduct(product);Tag Options
TagOptions allow administrators to easily manage tags on provisioned products by providing a template for a selection of tags that end users choose from. TagOptions are created by specifying a tag key with a set of allowed values and can be associated with both portfolios and products. When launching a product, both the TagOptions associated with the product and the containing portfolio are made available.
At the moment, TagOptions can only be deactivated in the console.
declare const portfolio: servicecatalog.Portfolio;
declare const product: servicecatalog.CloudFormationProduct;
const tagOptionsForPortfolio = new servicecatalog.TagOptions(this, 'OrgTagOptions', {
allowedValuesForTags: {
Group: ['finance', 'engineering', 'marketing', 'research'],
CostCenter: ['01', '02','03'],
},
});
portfolio.associateTagOptions(tagOptionsForPortfolio);
const tagOptionsForProduct = new servicecatalog.TagOptions(this, 'ProductTagOptions', {
allowedValuesForTags: {
Environment: ['dev', 'alpha', 'prod'],
},
});
product.associateTagOptions(tagOptionsForProduct);Constraints
Constraints are governance gestures that you place on product-portfolio associations that allow you to manage minimal launch permissions, notifications, and other optional actions that end users can perform on products. Using the CDK, if you do not explicitly associate a product to a portfolio and add a constraint, it will automatically add an association for you.
There are rules around how constraints are applied to portfolio-product associations.
For example, you can only have a single "launch role" constraint applied to a portfolio-product association.
If a misconfigured constraint is added, synth will fail with an error message.
Read more at Service Catalog Constraints.
Tag update constraint
Tag update constraints allow or disallow end users to update tags on resources associated with an AWS Service Catalog product upon provisioning. By default, if a Tag Update constraint is not configured, tag updating is not permitted. If tag updating is allowed, then new tags associated with the product or portfolio will be applied to provisioned resources during a provisioned product update.
declare const portfolio: servicecatalog.Portfolio;
declare const product: servicecatalog.CloudFormationProduct;
portfolio.addProduct(product);
portfolio.constrainTagUpdates(product);If you want to disable this feature later on, you can update it by setting the "allow" parameter to false:
declare const portfolio: servicecatalog.Portfolio;
declare const product: servicecatalog.CloudFormationProduct;
// to disable tag updates:
portfolio.constrainTagUpdates(product, {
allow: false,
});Notify on stack events
Allows users to subscribe an AWS SNS topic to a provisioned product's CloudFormation stack events.
When an end user provisions a product it creates a CloudFormation stack that notifies the subscribed topic on creation, edit, and delete events.
An individual SNS topic may only have a single subscription to any given portfolio-product association.
import * as sns from 'aws-cdk-lib/aws-sns';
declare const portfolio: servicecatalog.Portfolio;
declare const product: servicecatalog.CloudFormationProduct;
const topic1 = new sns.Topic(this, 'Topic1');
portfolio.notifyOnStackEvents(product, topic1);
const topic2 = new sns.Topic(this, 'Topic2');
portfolio.notifyOnStackEvents(product, topic2, {
description: 'description for topic2', // description is an optional field.
});CloudFormation template parameters constraint
CloudFormation template parameter constraints allow you to configure the provisioning parameters that are available to end users when they launch a product.
Template constraint rules consist of one or more assertions that define the default and/or allowable values for a product’s provisioning parameters.
You can configure multiple parameter constraints to govern the different provisioning parameters within your products.
For example, a rule might define the EC2 instance types that users can choose from when launching a product that includes one or more EC2 instances.
Parameter rules have an optional condition field that allow for rule application to consider conditional evaluations.
If a condition is specified, all assertions will be applied if the condition evaluates to true.
For information on rule-specific intrinsic functions to define rule conditions and assertions,
see AWS Rule Functions.
import * as cdk from 'aws-cdk-lib';
declare const portfolio: servicecatalog.Portfolio;
declare const product: servicecatalog.CloudFormationProduct;
portfolio.constrainCloudFormationParameters(product, {
rule: {
ruleName: 'testInstanceType',
condition: cdk.Fn.conditionEquals(cdk.Fn.ref('Environment'), 'test'),
assertions: [{
assert: cdk.Fn.conditionContains(['t2.micro', 't2.small'], cdk.Fn.ref('InstanceType')),
description: 'For test environment, the instance type should be small',
}],
},
});Set launch role
Allows you to configure a specific IAM role that Service Catalog assumes on behalf of the end user when launching a product.
By setting a launch role constraint, you can maintain least permissions for an end user when launching a product.
For example, a launch role can grant permissions for specific resource creation like an S3 bucket that the user.
The launch role must be assumed by the Service Catalog principal.
You can only have one launch role set for a portfolio-product association,
and you cannot set a launch role on a product that already has a StackSets deployment configured.
import * as iam from 'aws-cdk-lib/aws-iam';
declare const portfolio: servicecatalog.Portfolio;
declare const product: servicecatalog.CloudFormationProduct;
const launchRole = new iam.Role(this, 'LaunchRole', {
assumedBy: new iam.ServicePrincipal('servicecatalog.amazonaws.com'),
});
portfolio.setLaunchRole(product, launchRole);You can also set the launch role using just the name of a role which is locally deployed in end user accounts. This is useful for when roles and users are separately managed outside of the CDK. The given role must exist in both the account that creates the launch role constraint, as well as in any end user accounts that wish to provision a product with the launch role.
You can do this by passing in the role with an explicitly set name:
import * as iam from 'aws-cdk-lib/aws-iam';
declare const portfolio: servicecatalog.Portfolio;
declare const product: servicecatalog.CloudFormationProduct;
const launchRole = new iam.Role(this, 'LaunchRole', {
roleName: 'MyRole',
assumedBy: new iam.ServicePrincipal('servicecatalog.amazonaws.com'),
});
portfolio.setLocalLaunchRole(product, launchRole);Or you can simply pass in a role name and CDK will create a role with that name that trusts service catalog in the account:
import * as iam from 'aws-cdk-lib/aws-iam';
declare const portfolio: servicecatalog.Portfolio;
declare const product: servicecatalog.CloudFormationProduct;
const roleName = 'MyRole';
const launchRole: iam.IRole = portfolio.setLocalLaunchRoleName(product, roleName);See Launch Constraint documentation to understand the permissions that launch roles need.
Deploy with StackSets
A StackSets deployment constraint allows you to configure product deployment options using
AWS CloudFormation StackSets.
You can specify one or more accounts and regions into which stack instances will launch when the product is provisioned.
There is an additional field allowStackSetInstanceOperations that sets ability for end users to create, edit, or delete the stacks created by the StackSet.
By default, this field is set to false.
When launching a StackSets product, end users can select from the list of accounts and regions configured in the constraint to determine where the Stack Instances will deploy and the order of deployment.
You can only define one StackSets deployment configuration per portfolio-product association,
and you cannot both set a launch role and StackSets deployment configuration for an assocation.
import * as iam from 'aws-cdk-lib/aws-iam';
declare const portfolio: servicecatalog.Portfolio;
declare const product: servicecatalog.CloudFormationProduct;
const adminRole = new iam.Role(this, 'AdminRole', {
assumedBy: new iam.AccountRootPrincipal(),
});
portfolio.deployWithStackSets(product, {
accounts: ['012345678901', '012345678902', '012345678903'],
regions: ['us-west-1', 'us-east-1', 'us-west-2', 'us-east-1'],
adminRole: adminRole,
executionRoleName: 'SCStackSetExecutionRole', // Name of role deployed in end users accounts.
allowStackSetInstanceOperations: true,
});
