I also needed a ubuntu image. Creating this was for less painful than the Fedora image:

  • curl -o debootstrap.sh     https://raw.githubusercontent.com/docker/docker/master/contrib/mkimage/debootstrap
  • chmod 755 debootstrap.sh
  • sudo ./debootstrap.sh ubuntu --components=main,universe trusty
  • sudo tar -C ubuntu -c . | docker import - ubuntu:14.04.4
  • docker tag ubuntu:14.04.4-new ubuntu:14.04
