From edff63218619c1d466ebbfbc14fde1774c44ddfc Mon Sep 17 00:00:00 2001 From: "James E. Blair" Date: Thu, 19 Dec 2019 10:57:03 -0800 Subject: [PATCH] Add containerfile element This is a base element which uses a containerfile (Dockerfile) to build a container image, then the filesystem is extracted from that image and forms the root of the dib image. You can add as little or as much to the dockerfile as desired.
