How to build Fedora container images

Before we look at how the Fedora container base image is built, let’s define a base image and a layered image. A simple way to define a base image is an image that has no parent layer. But what does that concretely mean? It means a base image usually contains only the root file system (rootfs) of an operating system. The base image generally provides the tools needed to install software in order to create layered images.
