I'll pick this up again as soon as https://github.com/orgs/community/discussions/149347 is fixed.

This initial issue with ubuntu-24.04-arm has been fixed.

Now, it appears that the Lambda CI images used by us so far have not been maintained in 4 years and don't ship for arm64: https://hub.docker.com/r/lambci/lambda

We should probably modernize that part of our test suite ASAP.

#1268 fixes the issue related to outdated Lambda container images being used.

The new arm64 runners appear to be quite flaky when running the Lambda unit test. I don't think this is our fault and will give it a couple of days before trying again.

I actually wrote the original implementation of lambda in moto ;) Haven't touched it in years. We should coordinate with them if there are some issues with it on arm.

aha per https://github.com/lambci/docker-lambda?tab=readme-ov-file they've swapped to the official images here: https://github.com/aws/aws-lambda-base-images

I think, it's good. The issue was that we were nudging moto to use outdated container images for Lambda. But #1268 should take care of that.

Now it's just the flakiness of the GitHub arm runners that needs to get fixed.

#1275 did not fix reliability of unit tests on arm64. It's still flaky...

To work around flakiness of arm64 runners, I marked them as experimental for the time being. Experimental jobs that fail do not affect the result of the CI run.
