Latest AWS Lambda dotnet image is only for arm

[lionel-faber]

Describe the bug

The latest image uploaded today is for ARM and not AMD64

Expected Behavior

The last version had separate images for arm and amd64. Is this being migrated to use a single multi-platform image?

Current Behavior

The latest image seems to support only arm64.

Reproduction Steps

Build a docker image that uses the latest base image:

FROM public.ecr.aws/lambda/dotnet:7

The image always targets arm64

Possible Solution

This is breaking our deployments, as we use public.ecr.aws/lambda/dotnet:7, which up until today, was for platform linux/amd64. We've had to change our docker files to use public.ecr.aws/lambda/dotnet:7.2023.03.21.20 in order to work around this issue.

@arturomonge @lionel1704 Acknowledge this is an unintended breaking behavior. Previously we only had the amd64 image and as part of this month's patch we added an arm64. That was not intended to replace the amd64 and public.ecr.aws/lambda/dotnet:7 should have been a multi arch image similar to how we did .NET 6.

I'm tracking down what went wrong and will try and get this fixed up as soon as possible.

[normj]

New images have been pushed fixing the issue. The public.ecr.aws/lambda/dotnet:7 tag is now correctly a multi arch image so it will work for either amd64 or arm64.

Sorry for this mistake and thanks for your patience's.

@lionel1704 Please verify this at your end if this is fixed and confirm if we could close this issue.

This works as expected now. Thank you!
