https://github.com/moby/buildkit/releases is now available, along with https://github.com/docker/buildx/releases and https://github.com/moby/buildkit/releases syntax. We’ve released new features, bug fixes, performance improvements, and https://docs.docker.com/build/ for all of the Docker Build tools.
You can enable all of these new provenance records using the https://docs.docker.com/build/attestations/slsa-provenance/ in Buildx: $ docker buildx build --provenance=true -t
For example, suppose you want to build your own custom intermediate image based on https://www.docker.com/blog/how-to-use-the-alpine-docker-official-image/ that contains some development tools: $ docker buildx build.
You can then connect this Dockerfile to your OCI layout using the new oci-layout:// URI schema for the https://docs.docker.com/engine/reference/commandline/buildx_build/#build-context flag: $ docker buildx build.
