Multi-architecture support

[TimKnight-DWP]

We are building images for both amd64 and arm64 via Apko and Docker, I would like to be able to incert into both architectures and publish back up as a single Manifest reference both modified images

I don't think incert supports multi-arch images currently.

As a workaround, you can use the --platform command to create new images for each architecture then use the docker manifest commands to create a new multiarch image. That would look something like this (untested):

docker manifest create multiplatform_image:latest \
            x86image@DIGEST \
            armimage@DIGEST
 docker manifest push multiplatform_image:latest

You'd need to parse the digests out of the incert output.

Doing this, single shot, would be nice though.

I ran into this myself recently. Here's an attempt to add support for multi-arch: #51.

Oh wow, thanks. Will try to take a look soon.
