Build Link Attestation For Free

A single manifest is information about an image, such as layers, size, and digest. The docker manifest command also gives users additional information such as the os and architecture an image was built for.

A Docker tag is an alias pointing at a manifest (i.e., the name attribute of the component). A layer is unique and only stored once in a repository; however, many manifests are able to reference one layer. A Docker layer, for example, could be a specific operating system referenced by multiple Docker images.

$ 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.

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.

In docker build all builds finish by creating a container image and exporting it to docker images . buildx makes this step configurable allowing results to be exported directly to the client, oci image tarballs, registry etc. Buildx with docker driver currently only supports local, tarball exporter and image exporter.

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