Attestations

BuildKit supports creating and attaching attestations to build artifacts. Generated attestations use the in-toto attestation format.

The currently supported attestation types are:

Upon generation, attestations are attached differently to the export result:

  • For the image, oci and docker exporters, attestations are exported using the attached attestation storage.
  • For the local and tar exporters, attestations are written to separate files within the output directory.
