Great work on your YT and repo, much appreciated.

Trying to get Net8NativeContainers to work. Steps Clone repo Build NET8NativeContainers.sln cmd: docker build -f src/NET8NativeContainers/PutProduct/Dockerfile -t serverless-sample .

Any ideas?

Hi @chdev77 I also tried to build this image on my Windows machine but it seems to hang. I would say that native AOT and ARM64 (as seen in the screenshot) may not work well on Windows x86 machine. What OS and CPU architecture are you using?

Windows 10 x86

qemu: uncaught target signal 11 (Segmentation fault) - core dumped

Was able to reproduce this on my Win 10 in powershell and wsl.

Docker Architecture: x86_64
Docker version 24.0.7

Looking at the .NET Documentation, looks like it's a virtualization error: https://github.com/dotnet/core/blob/main/release-notes/8.0/supported-os.md#qemu

.NET 8 is not supported being run (emulated) via QEMU. QEMU is used, for example, to emulate Arm64 containers on x64, and vice versa.

@Beau-Gosse-dev @jeastham1993 - are these docker images intended to be built on a Arm64 (ie Graviton) machine or can they be built on an Amd64 machine?

Do the docker files need to be updated as advised here: https://devblogs.microsoft.com/dotnet/improving-multiplatform-container-support/

Yes, we only intended to support same-architecture builds. Adding support as outlined in that blog would be a great addition if we can get it to work for native AOT Lambdas.
