Powertools for AWS Lambda (TypeScript) Layer Publisher

This CDK app is meant to be used to publish Powertools for AWS Lambda (TypeScript) Lambda Layer. It is composed of a single stack deploying the Layer into the target account.

Usage

npm ci
npm run cdk deploy

By default it will package the layer with the latest version publicly available but you can force the public version to use with PowerToolsPackageVersion context variable:

npm run cdk deploy -- --context PowerToolsPackageVersion='0.9.0'

Tests

Units

npm run test

E2E

This will deploy and destroy several stacks in your AWS Account

npm run test:e2e

PS: You can force

• the lambda runtime to test with the RUNTIME env variable
• the Powertools for AWS Lambda (TypeScript) version with VERSION env variable

RUNTIME=node12.x VERSION=0.9.0 npm run test:e2e

How to add new region

• Activate new region in your TEST and PROD accounts
• Bootstrap a CDKToolkit stack in the new region

 cdk bootstrap aws://AWS_ACCOUNT/NEW_REGION   

• Deploy the first layer version to the new region, make sure to set the NEW_REGION in your AWS CLI configuration correctly, otherwise you will deploy to the wrong region

npm run cdk -w layers -- deploy --app cdk.out --context region=NEW_REGION 'LayerPublisherStack' --require-approval never --verbose 

• Run the bumper script to bring all layers to the same version across all regions
• Add new region to the worklflow in ./github/workflows/reusable_deploy_layer_stack.yml
• Document new region in docs/index.md
