Integrate Image Attestation For Free - Buildx No Default Attestations

I do hereby attest that this information is true, accurate and complete to the best of my knowledge and I understand that any falsification, omission, or concealment of material fact may subject me to administrative, civil, or criminal liability.?

Attestation is a confidential computing keystone. With attestation, workload owners can fully assert the trustworthiness of the hardware and software environment their workload is running in, regardless of the security posture of the underlying infrastructure provider.

To use Docker BuildKit by default, edit the Docker daemon configuration in /etc/docker/daemon. json as follows, and restart the daemon. If the /etc/docker/daemon. json file doesn't exist, create new file called daemon.

The provenance attestations include facts about the build process, including details such as: Build timestamps. Build parameters and environment. Version control metadata. Source code details.

Attestation Manifest Attestation manifests are attached to the root image index object, under a separate OCI image manifestopen_in_new. Each attestation manifest can contain multiple attestation blobs, with all the of the attestations in a manifest applying to a single platform manifest.

A single attestation can authorize identical images that are stored in multiple different locations or different registries, such as Artifact Registry, Container Registry, or an external container registry. At deploy time, Binary Authorization uses attestors to verify attestations.

$ docker buildx build --sbom=true --provenance=true . Provenance attestations are enabled by default, with the mode=min option. You can disable provenance attestations using the --provenance=false flag, or by setting the BUILDX_NO_DEFAULT_ATTESTATIONS environment variable.
