Feature: Lambda Layers

[heitorlessa]

Leaving this for consideration and see if we have customer traction as we go GA - Not necessarily a blocker for GA but could be helpful to customers.

If you'd like this to be available for all Python runtimes supported in addition to PyPi, please leave a 👍

Having an AWS managed & hosted lambda layer for this would be greatly appreciated!

In the meantime, this is available in the super helpful https://github.com/keithrozario/Klayers repo.

@mwarkentin True that. Unfortunately not usable in an enterprise context since this source is not safe to work with. An official layer from AWS would really help without the heavy lifting from customers site.

@am29d is currently working on it :) We're currently working on automating the Lambda Layers publishing pipeline to match our release process.

Awesome!

[keithrozario]

Can't wait!! :)

hey everyone - This is now AVAILABLE on SAR as of 1.4.0: https://github.com/awslabs/aws-lambda-powertools-python/releases/tag/v1.4.0

We've also taken the time to update the release process to ensure both PyPi and SAR semantic versioning match, so you can trust the CHANGELOG as you would normally :)

Is anyone aware of similar functionality for Serverless Framework that would allow us to embed the SAR app like this?

[am29d]

Hi @mwarkentin , the Serverless Framework can handle the Transform directive since v1.4.1:

serverless/serverless#5997

This should like this:

resources:
  Transform: AWS::Serverless-2016-10-31
  Resources:
    AwsLambdaPowertoolsPythonLayer:
      Type: AWS::Serverless::Application
      Properties:
        Location:
          ApplicationId: arn:aws:serverlessrepo:eu-west-1:057560766410:applications/aws-lambda-powertools-python-layer
          SemanticVersion: 1.3.1 # change to latest semantic version available in SAR

[mwarkentin]

@am29d would it make sense to add a section about this to the docs? I'm sure there are lots of Serverless Framework users who would be interested in using this installation method.
