This is a base image, not like a image from dockerfile.
There are couple ways to do this,
1. ISO
# mount -o loop ubuntu-14.04-server-amd64.iso /media/cdrom
# tar -C /media/cdrom -c . | docker import - guol/ubuntu14
2. Debian and Ubuntu, debootstrap way.
1. Install debootstrap.
2. Creat a chroot image folder.
3. Import this chroot folder into docker.
=====
# sudo zypper in debootstrap
# sudo debootstrap --arch amd64 sid /sid-chroot http://deb.debian.org/debian/
# sudo tar -C sid -c . | sudo docker import - sid
# sudo docker run -ti sid /bin/bash
3. fdebootstrap
