Currently cosign's method for associating SBOMs supports a single type of SBOM, so I simply pick the first when multiple are emitted. This can be controlled by restricting or reordering the sbom formats.

Is there an issue we can reference here (and in ko-build/ko#661) so we can switch to publishing both/all when the API supports it?

I wish the SBOM metadata were surfaced in a way we could plumb through to here, but the file list is effectively discarded today. We should consider ways to improve the way this is plumbed through.

This change attaches SBOMs to the `oci.SignedImage`s we build up, and these are published thanks to the previous commit in this series. I have added validation that for each of the examples we have that we scan download its SBOM with cosign. Fixes: chainguard-dev#145

Looks fine to me, given that we can't just fix cosign immediately. |
