This debian image attempts to immitate a standard (non docker) ubuntu workstation.
It contains the essential packages pre-installed, and a non root user
(with sudo privileges) named megatron
$ docker run --rm -it dannyben/debian
Since this image sets the user to megatron, if you need to execute commands
that require root access in your image, you need to use this pattern:
FROM dannyben/debian
USER root
# root stuff goes here
USER megatron
