# 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
|
||||
# dnf 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
