Docker is a great way to fully describe and implement an installed Linux environment, and we make use of it at work as part of our continuous integration system to provide a clean environment for the jobs that we run.Unfortunately, the main public repo ( currently only contains images for x64, so if you want a different architecture, you may need to build it yourself.

In this situation, I required a Fedora 23 image on Power PC. I started with a working Fedora 23 in PowerKVM.

The problems I had to address:

  • You can't run nested KVM instances, and imagefactory wants to use it by default
  • Passing the proxy settings to the guest environment has to be done via a kernel parameter
  • Only the nominated .ks file iss passed to the installation environment (files that are included are not available)


So, assuming you are logged in to a working Power environment:

  • git clone
  • cd spin-kickstarts
  • cp fedora-docker-base.ks fedora-docker-ppc.ks
  • merge in the contents of fedora-docker-base-ppc.ks to fedora-docker-ppc.ks (only the first .ks file is passed to the install environment, so includes do not seem to work)
  • dnf install yum-utils koji-builder strace mock kernel-firmware ntp ntpdate rsyslog oz imagefactory imagefactory-plugins-TinMan imagefactory-plugins-Docker imagefactory-plugins-vSphere imagefactory-plugins-ovfcommon imagefactory-plugins imagefactory-plugins-OVA imagefactory-plugins-EC2 imagefactory-plugins-RHEVM python-psphere VMDKstream pykickstart
  • edit /etc/oz/oz.cfg and set the virtualisation type to 'qemu'
  • create ../fedora-23.tdl (documented here):<template>
            <install type='url'>
        <kernelparam>proxy=http://<proxy server>:<proxy port></kernelparam>

  • imagefactory --debug target_image --template ../fedora-23.tdl --parameter offline_icicle true --file-parameter install_script $(pwd)/fedora-docker-ppc.ks docker
  • This should have created a file like /var/lib/imagefactory/storage/<some hash>.body
  • docker load --input /var/lib/imagefactory/storage/<some hash>.body
  • docker images (your new image will be called rawhide:latest)
  • docker tag <id> fedora:23
  • docker tag <id> fedora:latest
  • docker tag <id> fedora:rawhide
  • docker run fedora:23 ls
