Is OpenFunction compatible with ARM architectures? Like Mac M1s?

[salaboy]

Description

I couldn't run OpenFunctions in a local KinD cluster running on an M1 Mac Machine (arm64) mostly because there are no openfunction builds for arm. Did I missed something?

Environmental

Mac OS, arm64, Kubernetes KinD

Expected behavior
Openfunction images should be available for arm64 architecture.

Actual behavior
Failed with:

WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested

To Reproduce
Steps to reproduce the behavior:

1. '..'
2. '...'
3. '....'
4. See error

@salaboy Sorry for the delay. OpenFunction's arm support is currently blocked at the build part, the buildpacks we used currently doesn't support to build images for arm yet.

@salaboy Sorry for the delay. OpenFunction's arm support is currently blocked at the build part, the buildpacks we used currently doesn't support to build images for arm yet.

@salaboy we haven't build arm64 images for OpenFunction yet because the builder we use haven't supported build arm64 images well enough, for example:

For go functions:
https://github.com/OpenFunction/builder/tree/main/builders/go117
bazel run --platforms=@io_bazel_rules_go//go/toolchain:linux_amd64 //builders/go117/stack:build

The base image is amd64 only for now , we can upgrade it to a multi-arch one: https://github.com/OpenFunction/builder/blob/main/builders/go117/stack/parent.Dockerfile#L15

Python base image has similar issue https://github.com/OpenFunction/builder/blob/main/builders/py39/stack/parent.Dockerfile#L15

Another problem of go buildpacks is the binary is still amd64 only https://github.com/OpenFunction/builder/blob/main/builders/go117/stack/parent.Dockerfile#L38

Also we noticed an on-going process of the arm64 support in cnb(cloud native buildpacks) : buildpacks/rfcs#294

+1 ARM64 is very much in demand these days

If ignore the builder step and only want to deploy openfunction on ARM64, how can build relevant ARM64 images about openfunction？thanks
