Which is funny because Moby split the Dockerfile format from Docker, so you no longer need the Dockerfile format to make Docker images. At the top of a “Dockerfile” is

    # syntax=docker/dockerfile:v1

Which is a Docker image that translates the declarative syntax into the commands sent to the low-level builder. That syntax is pointing to a Docker image name and tag (`docker/dockerfile:v1`) that Buildkit pulls down and feeds the passed commands into. Technically, that could be anything. If you wanted to put in the work, you could write a Buildkit frontend for Ansible or Chef and use that to configure the image.

So, on the list of “4 things Docker is”, they were wrong on the first one.
