Kaniko: Build container images in Kubernetes
This work (and related efforts like Img and Buildah) is a big deal.<p>Right now docker images and Dockerfiles are joined at the hip to the Docker daemon.<p>It works great for local development, but for hosted systems that run on containers, it&#x27;s a dire mess. I have personally slammed head-first into Docker-in-Docker quagmires on Kubernetes and Concourse. Not knowing the particular arcane rites and having neither sufficient eye of newt nor sufficient patience to get it to work, I like everyone else in the universe gave up.<p>Not an acceptable state of affairs, given the many problems of Dockerfiles in themselves. Dockerfiles force an ugly choice. You can have ease of development or you can have fast, safe production images. But you can&#x27;t really have both.<p>Kaniko is another step in the direction of divorcing docker images as a means of distributing bits from Dockerfiles as a means of describing docker images from Docker daemons as a means for assembling the images. All three are different and should no longer be conflated.<p>Disclosure: I work for Pivotal, we have a lot of stuff that does stuff with containers.
