Cdk-standalone-deployer NPM

CDK App deployer - Link

TL;DR

As a workshop studio writer I run

npx cdk-standalone-deployer setup-workshop --workshop-id 12345678-aabb-a12a-1234-1234567890 --cdk-project-path ./myCdkApp

As a blog post writer I run

npx cdk-standalone-deployer --github-repo-name <YOUR GITHUB ALIAS>/<YOUR REPO NAME>  --github-repo-branch <GITHUB BRANCH> --cdk-project-path <CDK PROJECT PATH> --public-read --install-command "npm install" --build-command "npm run build"

What is it ?

This Command Line Interface (CLI) enables to easily create click to deploy link of an AWS CDK app code hosted on Github such as:

If you follow this link, it will deploy the example contains in the aws-samples/aws-cdk-examples repo typescript/lambda-layer folder (which consist of a simple Lambda layer CDK app) into your AWS account.

The CLI will take your CDK app repository name and public S3 bucket to publish the Deployer stack to. It will then synthesize and publish the template with the right configuration without any modification of your code.

This tool is leveraging the CDKStandaloneDeployer construct which will create a Cloud Formation template starting an AWS Code Build project which will run a cdk bootstrap and cdk deploy from the given source (being either a zip in an S3 bucket or a github repository). For details about the available properties, please refer to the CDKStandaloneDeployer construct API documentation.

Getting started example

Assuming you are the owner of the aws-samples/aws-cdk-examples and you want to create a click to deploy link, you just have to run the following command:

npx cdk-standalone-deployer --github-repo-name aws-samples/aws-cdk-examples --cdk-project-path typescript/lambda-layer --github-repo-branch master --public-read --install-command "npm install" --build-command "npm run build"

Check access permissions ...

Generating the deployer stack ...
Generating deployer for https://github.com/aws-samples/aws-cdk-examples/tree/master/typescript/lambda-layer CDK app ...
CDK Deployer CloudFormation template generated. Uploading it to S3 ...
Uploading CDK Deployer CloudFormation template to S3 bucket cdk-depl-aws-samples-aws-cdk-examples-master-9xf/cdk-standalone-deployer-cfn-template.json ...
You can now add the following markdown to your README.md : [![click-to-deploy](https://img.shields.io/badge/Click%20to-CDK%20Deploy-blue)](https://console.aws.amazon.com/cloudformation/home#/stacks/new?stackName=cdkDeployer&templateURL=https://cdk-depl-aws-samples-aws-cdk-examples-master-9xf.s3.amazonaws.com/cdk-standalone-deployer-cfn-template.json)

The CLI will 1. Check your AWS credentials 1. Generate the CDK Deployer CloudFormation template 1. Upload it to the S3 bucket cdk-depl-aws-samples-aws-cdk-examples-master-9xf 1. Print the markdown to add to your README.md

Your customer can then just click on the link and deploy your CDK app in their AWS account.

Usage

Prerequisite

You need to have AWS credentials exported in your environment. You can do so by running aws configure or by exporting the following environment variables:

export AWS_ACCESS_KEY_ID=XXXX
export AWS_SECRET_ACCESS_KEY=XXXX
export AWS_SESSION_TOKEN=XXXX

A minimal set of permissions has to be associated with your credentials to be able to:

Create an S3 bucket (if bucket not provided)
Put an object to the S3 bucket
Get caller identity (to check crendentials validity)

The following policy will do the trick:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "CDKDeployerCLIPermissions",
            "Effect": "Allow",
            "Action": [
                "s3:PutObject",
                "s3:CreateBucket",
                "sts:GetCallerIdentity",
            ],
            "Resource": "*"
        }
    ]
}

Usage: cli [options]

A simple tool to make your CDK app deployable through a click to deploy button.

  --cdk-parameters [pair...]         add an entry (or several separated by a space) key=value that will be passed to the cdk app through context (--context)

BuildSpec focus

As mentionned before the CDKStandaloneDeployer construct rely on AWS CodeBuild. It provides default install/build/bootstrap/deploy/destroy command but you can as well specify your own.

To do so, you have 2 options:

if you have a deploy and destroy buildspec yaml file already existing in your CDK app repository, you can use them by specify --deploy-buildspec-name and --destroy-buildspec-name options.
Or you an specify the install/build/bootstrap/deploy/destroy command using --install-command, --build-command, --bootstrap-command, --deploy-command and --destroy-command. Only --install-command is required then.

CDK parameters

You can also pass parameters to your CDK app through context using the --cdk-parameters option. It takes a list of key=value pair separated by a space. Those parameters will be then customizable by the user when deploying the stack through the AWS CloudFormation Console.

Architecture

CDK App deployer - Workshop Studio

TL;DR

npx cdk-standalone-deployer setup-workshop --workshop-id 12345678-aabb-a12a-1234-1234567890 --cdk-project-path ./myCdkApp

=> CDK App automatically deployed in your Workshop Studio attendees AWS account

What is it ?

**This Command Line Interface (CLI) eases the deployment of CDK app for Wokshop studio accounts provisionning.

This is tipically used by Workshop editor that want to pre provision resources in teams accounts for events and want to use CDK to create this initial infrastructure.**

This tool is leveraging the CDKStandaloneDeployer construct which will create a Cloud Formation template starting an AWS Code Build project which will run a cdk bootstrap and cdk deploy from the given source (automatically zipped from the cdk app path provided). For details about the available properties, please refer to the CDKStandaloneDeployer construct API documentation.

Getting started example

Assuming you have a workshop repo locally cloned:

tfc-analytics-ara-demo on  mainline [!] on ☁️  (us-east-1) took 25s 
❯ ls
README.md        myCdkApp          assets           content          contentspec.yaml static

Assuming this repo contains a cdk app (myCdkApp here) committed in this repo.

tfc-analytics-ara-demo on  mainline [!] on ☁️  (us-east-1) 
❯ ls myCdkApp 
README.md            app.py               cdk.out              requirements.txt     tests
als_ara              cdk.json             requirements-dev.txt source.bat

Provding your Workshop ID and your path of your cdk app to the cdk-standalone-deployer npx executable, will setup your CDKApp to be deployed as part of your workshop event for you.

tfc-analytics-ara-demo on  mainline [!] on ☁️  (us-east-1)
