Self Contained Change: This change will only affect new users who use the new image.
Container Minimal Image
Summary
Produce a new container image that contains as little as possible, but also still provides the ability to install packages from dnf repositories.
Builds for Fedora 26 Alpha can be found here: http://dl.fedoraproject.org/pub/fedora/linux/releases/test/26_Alpha/
Koji builds: https://koji.fedoraproject.org/koji/packageinfo?packageID=23806
Example:
curl http://dl.fedoraproject.org/pub/fedora/linux/releases/test/26_Alpha/Docker/x86_64/images/Fedora-Container-Minimal-Base-26_Alpha-1.7.x86_64.tar.xz | docker load docker run --rm -ti fedora-container-minimal-base-26_alpha-1.7.x86_64 bash microdnf install httpd
Currently, builds of this are not automatically pushed to any registry. The plan however is for this to be regularly updated once Fedora 26 final is released.

Detailed Description
As a user of Fedora I'd like to build containers based on an image that is a little more lightweight than the current base container image that is produced in Fedora. We have a proof of concept kickstart [1] that will create such an image. It is a work in progress.
