[GrahamCampbell]

Is your feature request related to a problem? Please describe.

Is AL 2023 coming to Lambda? Is there a roadmap for this? How will quarterly releases be treated by Lambda?

Describe the solution you'd like

AL 2023 available on Lambda for both x86_64 and arm64.

Describe alternatives you've considered

Additional context

I have considered building my own image based on AL2023 for my ruby-based lambda runtime. The Dockerfile looks like this:

FROM amazonlinux:2023

RUN dnf install -y ruby \
  && dnf clean all

This adds Ruby 3.2 to the image which is the supported version going forward (2.7 is deprecated).

However, I would prefer to have this runtime supported in Lambda rather than building a custom image as it is a lot simpler to set up apps using the serverless framework.

As per aws/aws-lambda-base-images#92 (comment) (and also tracked in aws/aws-lambda-base-images#59 ) there's the following available now:

a preview AWS Lambda base container image for AL2023, named ‘provided.al2023’.

There's also the Node 20 Lambda runtime based upon AL2023 (see aws/aws-lambda-base-images#91 (comment) ), and the Corretto 21 runtime (see aws/aws-lambda-base-images#113 (comment) ).

I'll keep this issue open until the Lambda GA of AL2023 images.

Hello @stewartsmith , is there an ETA for this? I see it was moved to Coming Soon and would appreciate if there was a rough estimate of release date?

[GrahamCampbell]

As I understand, it is coming in the next few months.

With the announcement that @ozbenh pointed to, I'm going to resolve this issue as completed. Further documentation and more runtimes will follow.

See the Introducing the Amazon Linux 2023 runtime for AWS Lambda blog post for more information.

One thing I particularly like is how much smaller the AL2023 base image is: 40MB versus the 100MB of AL2! This is thanks to the AL2023 minimal container image.
