Cdk-import NPM

cdk-import

Generates CDK constructs from external sources such as public CloudFormation Registry types and modules (L1s) as well as AWS Service Catalog product versions.

IMPORTANT The AWS CDK CLI has feature called cdk import, which can be used to import ("adopt") existing resources into CloudFormation control, so that they can be mutated by CDK updates later. The naming collission is unfortunate, but this repository has nothing to do with that feature. For more information on the feature to import existing AWS resources into CDK/CloudFormation stacks, see the CLI documentation on cdk import.

Installation

npm install -g cdk-import

Usage

There are currently two sources that resources can be generated from. The subcommand cfn is used to import from CloudFormation Registry, sc is used to import AWS Service Catalog products. There are shared general options for output directories and target language. You will need AWS_REGION variable configured in your environment.

Usage:
  cdk-import SUBCOMMAND (cfn or sc) [parameters]

General Options:
  -l, --language     Output programming language                               [string]
  -o, --outdir       Output directory                                          [string]
  --go-module        Go module name (required if language is "golang")         [string]
  --java-package     Java package name (required if language is "java")        [string]
  --csharp-namespace C# namespace (optional if language is "csharp",           [string]
                     defaults to resource name.)
  -h, --help         Show usage info (include subcommand to see specific help) [boolean]

CloudFormation Registry Usage

Usage:
  cdk-import cfn -l LANGUAGE RESOURCE-NAME[@VERSION]

Options:
  -l, --language     Output programming language                        [string]
  -o, --outdir       Output directory                                   [string]  [default: "."]
  -s, --schema-file  Read schema from a file (instead of CFN registry)  [string]
  --go-module        Module name (required if language is "golang")     [string]
  --java-package     Java package name (required if language is "java") [string]
  --csharp-namespace C# namespace (optional if language is "csharp",    [string]
                     defaults to resource name.)
  -h, --help         Show this usage info                               [boolean]

The --language option specifies the output programming language. Supported languages: typescript, java, python, csharp and golang.

Output will be generated relative to --outdir which defaults to the current working directory.

By default, the resource schema will be read from the AWS CloudFormation Registry, using the current AWS credentials (configured using environment variables). If you have a copy of the JSON schema that describes the resource properties in a local file, you can pass --schema-file to specify the file. This will bypass the query to the CloudFormation Registry. It expects the exact same Schema contents as returned by DescribeType.

The following section describes language-specific behavior.

Java

The --java-package option is required and should include the Java package name to use for generated classes. Normally, this will be a sub-package of your project's package.

Java source files are generates in Maven-compatible structure under $outdir/src/main/java/PACKAGE/ where PACKAGE is based on --java-package.

For example:

cdk-import -l java --java-package com.foo.bar.resources AWSQS::EKS::Cluster

Will generate class source files under src/main/java/com/foo/bar/resources. All the classes will be under the package com.foo.bar.resources.

Python

A Python submodule is generated under $outdir/MODULE_NAME/ where MODULE_NAME is based on the name of the resource (AWSQS::EKS::Cluster => awsqs_eks_cluster).

For example:

cdk-import -l python AWSQS::EKS::Cluster

Will generate a subdirectory awsqs_eks_cluster with a Python module that can be imported.

CSharp

A .csproj is generated under $outdir/RESOURCE/ where RESOURCE is the resource name (AWSQS::EKS::Cluster).

For example:

cdk-import -l csharp AWSQS::EKS::Cluster

Will generate a directory AWSQS::EKS::Cluster with a .csproj. This can be used in a .NET solution.

TypeScript

A TypeScript file will be generated under $outdir/MODULE where MODULE is derived from the resource name.

For example:

cdk-import -l typescript -o src AWSQS::EKS::Cluster

Will generate a file src/awsqs-eks-cluster.ts (note the usage of -o above).

Go

If -l golang is used, the --go-module option is required and must reflect the Go module name of the parent project module.

A Go submodule will be generated under $outdir/PACKAGE where PACKAGE is derived from the resource name (AWSQS::EKS::Cluster => awsqs-eks-cluster).

For example:

cdk-import -l golang --go-module "github.com/foo/bar" AWSQS::EKS::Cluster

Will generate a Go module under: awsqs-eks-cluster.

Examples

Generates constructs for the latest version AWSQS::EKS::Cluster in TypeScript:

cdk-import cfn -l typescript AWSQS::EKS::Cluster

Generates construct in Go for a specific resource version:

cdk-import cfn -l golang --go-module "github.com/account/repo" AWSQS::EKS::Cluster@1.2.0

Generates construct in Python under the "src" subfolder instead of working directory:

cdk-import cfn -l python -o src AWSQS::EKS::Cluster

Generates construct in Java and identifies the resource type by its ARN:

cdk-import cfn -l java --java-package "com.acme.myproject" arn:aws:cloudformation:...

Modules are also supported:

cdk-import cfn AWSQS::CheckPoint::CloudGuardQS::MODULE

AWS Service Catalog Usage

The cdk-import tool generates a user friendly version of a provisioned product that becomes a normal cdk construct that you can use within a cdk app. You can currently either specify a specific product version or generate all available products. The tool will call APIs and attempt to resolve default artifact and launch path for a product, if a singular product version or launch path cannot be resolved, it will throw an error. You will need Service Catalog end-user read permissions to call these APIs.

Usage:
  cdk-import sc -l LANGUAGE
  cdk-import sc -l LANGUAGE --product-id PRODUCT-ID --provisioning-artifact-id PROVISIONING-ARTIFACT-ID --path-id LAUNCH-PATH-ID

Options:
  -l, --language                 Output programming language                          [string]
  -o, --outdir                   Output directory (default "./sc-products")           [string]
  --product-id                   Product Id                                           [string]
  --provisioning-artifact-id     Provisioning artifact Id                             [string]
  --path-id                      Launch path Id                                       [string]
  --go-module                    Module name (required if language is "golang")       [string]
  --java-package                 Java package name (required if language is "java")   [string]
  --csharp-namespace             C# namespace (optional if language is "csharp",      [string]
                                 defaults to resource name.)
  -h, --help                     Show this usage info                                 [boolean]

The --language option specifies the output programming language. Supported languages: typescript, java, python, csharp and golang.

If you are using csharp, you must specify a --csharp-namespace within your project.

Output will be generated relative to --outdir which defaults to the current working directory under ./sc-products.

Examples

Generates constructs in python for the latest product versions as importable modules in your local workspace.

cdk-import sc -l python -o .
