# This is a minimal CentOS kickstart designed for docker.
# It will not produce a bootable system
# To use this kickstart, run the following command
# livemedia-creator --make-tar \
#   --iso=/path/to/boot.iso  \
#   --ks=centos-7.ks \
#   --image-name=centos-root.tar.xz
#
# Once the image has been generated, it can be imported into docker
# by using: cat centos-root.tar.xz | docker import -i imagename
