aws-lambda-java-base-images VS aws-lambda-base-images

After waiting more than a year for an official release of AWS Lambda support Java LTS release 17, and seeing Amazon continue to demure from announcing a release date, I finally just rolled my own custom base image to let me make use of these great new Java releases in a serverless environment. If that sounds useful, you can find base images for Java 17 and 18 at aleph0io/lambda/java in the ECR Public Gallery. Brief writeup here and source code on GitHub for the curious. I've built production services on these custom images, and so far they work a treat. If you pick them up, let me know what you build with them!

If you setup user namespace, the child processes will inherit that namespace. The difference is that plan9 is fully built on this idea and isn't multi-user, on linux you have to opt-in to this. It's very useful and underused (mostly used by containers). I wanted to ship my AWS lambdas this way, but sadly AWS lambdas don't allow usernamespaces.

From their GitHub issues, as user mentions using public.ecr.aws/lambda/python:3.11.2023.11.18.02 which is the previous build including yum.

Ruby 2.7 is reaching its end of life come next March. While other runtimes received updates, there is none in sight for Ruby. Mind you, Ruby recently had its annual Christmas release, gifting v3.2 to the community.

There is a short thread at the issue tracker of the official Docker image repository over at GitHub [1], which has a tumbleweed-y feel to it.

Is this a signal for everyone still rocking Ruby lambdas to either plan a migration to another language or to roll their own custom container image?

We're tracking time without an official Java 17 Lambda image at https://github.com/aws/aws-lambda-base-images/issues/29. I'd understand older services to be late to the party, but AWS Lambda?

After a year, Amazon still hasn't released an officially-supported AWS Lambda Base Image or Runtime for Java 17. But I needed it, so I made one. You can find the images themselves at https://gallery.ecr.aws/aleph0io/lambda/java, and the source code on GitHub at https://github.com/aws/aws-lambda-base-images.
