[jeffmaury]

Issue Description

While preparing a demo, I'm trying to build https://github.com/redhat-developer/podman-desktop-demo/blob/main/primary-podify-demo/front/Dockerfile or https://github.com/redhat-developer/podman-desktop-demo/blob/main/primary-podify-demo/backend/Dockerfile with multi arch and got an error while building the amd64 image

Steps to reproduce the issue

Steps to reproduce the issue

i think --arch is a string in podman and buildah and therefore can only be one of them? I don't see anything about a list or concatenating them with commas.

@nalind agree?

[nalind]

Yes, --arch expects only one value. At some point we figured out that trying to support multiple values for that made it hard to figure out how flags that combine with it like --os and --variant would be expected to work. Using --platform to specify them as one or more groups is easier (for me, at least) to reason about, and --platform started accepting a comma-separated list of platform specs in buildah 1.23, which was in the podman 3.4 era. I think there might be some logic to try to make it work if we notice that --arch was given a list, but I'd recommend using --platform instead regardless.

But anyway, did yum output any error information when it failed? Is it crashing, or trying to do something that the emulator can't make work? Does an arm64 build succeed?
