I understand and accept that you're fine with Dockerfiles, but your statement is overbroad: Heroku and Pivotal aren't the only ones in the industry frustrated at the shortcomings of Dockerfiles. I'm glad alternatives are growing in number. (Others include Buildah, to be included in RHEL 8; and the Docker image support for Bazel.)

As well as Kaniko, Makisu, Orca and I've genuinely lost track.

Though buildpacks differ from most of these by skipping Dockerfiles altogether.

Thanks for that list. If I'm not mistaken, Buildah and Bazel skip Dockerfiles as well; not sure of the three you just named.

I forgot Jib! It also skips Dockerfiles.
