Multi-arch images

[saada]

How would k8s-image-swapper handle multi-arch images that contain both arm and amd64 images. Is there a way to sync all the architectures from third party into ECR?

@saada Good question, I haven't had the need for multi-arch images yet. We're using skopeo (see) to copy the image which should already handle multi-arch images.

Have you encountered a problem?

[saada]

No particular issue. Just wondering if there's documentation or guidelines on how it worked. So maybe I have to look at skopeo in particular

You can find documentation here, but not specifically about multi-arch images. I'm happy to add it if you feel there should be more on this topic.

k8s-image-swapper uses skopeo internally to copy images. The parameter in question is set to all, which copies all architecture images to the target registry.

skopeo:
