    There are so many interesting things to share:

    1. google/go-containerregistry has some super helpful tools, in fact I raised a PR to make sure they build ppc64le binaries #1680

    crane is a tool for interacting with remote images and registries.

    You can extract a binary my-util for a given architecture using:

    crane export ppc64le/image-id:tag image.tar
tar xvf image.tar bin/my-util

    You can extract a binary from a manifest-listed image using:

    crane export --platform ppc64le image-id:tag image.tar
tar xvf image.tar bin/my-util
    1. I found ko which enables multiarch builds (a complete manifest list image).
    2. Quickly checking manifest-list image’s supported architectures
    podman manifest inspect registry.k8s.io/sig-storage/nfs-subdir-external-provisioner:v4.0.2 | jq -r '.manifests[].platform.architecture'
amd64
arm
