    There is no need to install the image from scratch, I found this answer where you can make docker to download the desired version and I adapted to my needs: 

    sudo docker run ubuntu:12.04 cat /etc/issue

    returns this:

    Unable to find image 'ubuntu:12.04' locally
12.04: Pulling from library/ubuntu
Downloading
...
Status: Downloaded newer image for ubuntu:12.04
Ubuntu 12.04.4 LTS \n \l

    or alternatively you can use:

    sudo docker pull ubuntu:12.04

    and then run that image with 

    sudo docker run -i -t ubuntu:12.04 /bin/bash

    to make sure in the prompt try to see the version:

    cat /etc/issue

    PS. Dont forget to commit the changes, before exiting, otherwise are lost. First get the container id using this command:

    sudo docker ps -l

    Commit changes to the container:

    sudo docker commit <container_id> repo/img1

    Then run the container:

    sudo docker run -i -t repo/img1 /bin/bash
