fedora-kickstarts/fedora-docker-base.ks

# This is a minimal Fedora install designed to serve as a Docker base image. 
#
# To keep this image minimal it only installs English language. You need to change
# yum configuration in order to enable other languages.
#
###  Hacking on this image ###
# This kickstart is processed using Anaconda-in-ImageFactory (via Koji typically),
# but you can run imagefactory locally too.
#
# To do so, testing local changes, first you'll need a TDL file.  I store one here:
# https://git.fedorahosted.org/cgit/fedora-atomic.git/tree/fedora-atomic-rawhide.tdl
# 
# Then, once you have imagefactory and imagefactory-plugins installed, run:
# 
#   imagefactory --debug target_image --template /path/to/fedora-atomic-rawhide.tdl --parameter offline_icicle true --file-parameter install_script $(pwd)/fedora-docker-base.ks docker
#
