DON’T REALLY DO THAT
docker run -t -i <base image> /bin/bash
Do some stuff in container : apt-get install nginx
Exit container and run :
docker commit -m "message" -a "your name" <container_id> ouruser/test:v2(target)

Dockerfile

mkdir /image
touch /image/Dockerfile
echo "# This is a comment
FROM ubuntu:14.04
MAINTAINER Thomas <thomas@example.com>
RUN apt-get update && apt-get install -y nginx" > /image/Dockerfile

Built it : docker build -t repo/image:tag .
Use it : docker run -t -i repo/image:tag /bin/bash
