Maintenance: Verify Output of Layer Deployment (Partitions) GitHub Action

[svozza]

Summary

Currently we are manually verifying the output of the GitHub action that deploys the Lambda layers to GovCloud and China regions. The validation steps are as follows:

Verify GovCloud Layers (Gamma): Download the AWSLambdaPowertoolsTypeScriptV2-us-gov-east-1.json and AWSLambdaPowertoolsTypeScriptV2-us-gov-west-1.json ZIP files. Unzip the files, inspect the JSON files therein and ensure the version number in the Description field (i.e., Powertools for AWS Lambda (TypeScript) version 2.20.0) and the layer version in the LayerVersionArn field (i.e., arn:aws-us-gov:lambda:us-gov-east-1:164754790254:layer:AWSLambdaPowertoolsTypeScriptV2:31) are correct.

Verify China Layer (Gamma): Download the AWSLambdaPowertoolsTypeScriptV2-cn-north-1.json ZIP file. Unzip
the file, inspect the JSON file therein and ensure the version number in the Description field
(i.e., Powertools for AWS Lambda (TypeScript) version 2.20.0) and the layer version in the LayerVersionArn field
(i.e., arn:aws-cn:lambda:cn-north-1:498595349401:layer:AWSLambdaPowertoolsTypeScriptV2:31) are correct.

We could automate this validation as part of the GitHub action and fail the action if the validation fails.

Why is this needed?

This will remove four manual steps from our release process and reduce the number of GitHub actions we have.

Which area does this relate to?

Automation

Solution

Currently we are already verifying the checksum of the layer:

powertools-lambda-typescript/.github/workflows/layers_partitions.yml

Line 164 in 4226058

test "$REMOTE_SHA" == "$LOCAL_SHA" && echo "SHA OK: ${LOCAL_SHA}" || exit 1

We can add two further checks to check the Description and LayerVersionArn fields.

In addtion we can also deprecate the Layer Verification (Partition) action:

Acknowledgment

• This request meets Powertools for AWS Lambda (TypeScript) Tenets
• Should this be considered in other Powertools for AWS Lambda languages? i.e. Python, Java, and .NET
