Store Image Attestation For Free

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.

$ 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.

Setting the DOCKER_BUILDKIT environment variable to 0 will disable BuildKit. However, changing the Docker engine configuration doesn't have the same disabling effect on BuildKit.

A Docker registry is a system for versioning, storing and distributing Docker images. DockerHub is a hosted registry used by default when installing the Docker engine, but there are other hosted registries available for public use such as AWS and Google's own registries.

It's the verifiable information about software artifacts describing where, when and how something was produced. For higher SLSA levels and more resilient integrity guarantees, provenance requirements are stricter and need a deeper, more technical understanding of the predicate.

For example, --provenance=false can be used to disable all provenance attestations, while --provenance=true can be used to enable all provenance attestations. By default, a minimal provenance attestation will be created for.
