Building containers with func

[d-m]

Is it possible to specify the architecture, or build multiple architectures, using func? I'm using an ARM Mac with Podman and would like to also build amd64 images as well.

The buildpack build strategy should always build amd64 at this time.
The s2i strategy should build for host architecture. You could however force s2i strategy to build for other architecture by specifying builder image --builder={image for the desired arch}.

Also not that build for another architecture will be extremely slow. If architecture of your host machine and cluster differs I recommend on-cluster-build: func deploy --remote ....

Looks like buildpack get confused and create an image with mixed architecture. Image marked as arm64 but contains x86 code.

I using podman 5.1.1 on a Macbook with M3 and func v0.40.0.

When I build a simple go function after func create -l go hello with func build and then inspect the image with podman inspect it says Architechture arm64.
When running with func run I get the error rosetta error: failed to open elf at /lib64/ld-linux-x86-64.so.2 which indicates there are x86 code in it.
