Changes

  • The image build is reproducible: if the func-utils binary is unchanged so are the images.

    Currently we have too many images that are basically identical but differing in some metadata.
    This change will limit this package proliferation.

  • Provenance of image origin using cryptographic signatures. Probably nobody uses that, but if somebody wanted to verify that the func-utils image originates form the knative org, now they can.

* The image build is reproducible:
  if the func-utils binary is unchanged so are the images.

* Provenance of images using cryptographic signatures.

Great; that's precisely the kind of reproducibility we need to start ensuring a secure image supply chain.
