What is Ubuntu?
Ubuntu is a Debian-based Linux operating system, with Unity as its default desktop environment. It is based on free software and named after the Southern African philosophy of ubuntu (literally, "human-ness"), which often is translated as "humanity towards others" or "the belief in a universal bond of sharing that connects all humanity".
Development of Ubuntu is led by UK-based Canonical Ltd., a company owned by South African entrepreneur Mark Shuttleworth. Canonical generates revenue through the sale of technical support and other services related to Ubuntu. The Ubuntu project is publicly committed to the principles of open-source software development; people are encouraged to use free software, study how it works, improve upon it, and distribute it.

wt is root password for ubuntu:14.04 container ?
@parag4code if yout use the tag wily, so the command : docker pull ubuntu:wily, you will have the cloudimg image of wily because this pull use that Dockfile : https://github.com/tianon/docker-brew-ubuntu-core/blob/e68c4b0d4c860a8e0547cfea6f1b07f0adb9ff46/wily/Dockerfile
where to find the ubuntu-wily-core-cloudimg-amd64-root.tar.gz file?
Why all ubuntu docker images have a "/core" file? Is this a core dump? Is it necessary?
should your images always be small in size ?, i guess the point of docker images to be light weight?
32 bit are available ?
Is this a server version of Ubuntu?thanks.
the size so big so foo.
use something like VirtualBox for the desktop version. Docker is not for being able to run window managers. Maybe linux gurus can make it happen, but is not for the faint hearted.
Also try to read more on understanding what a docker container is and how it is built, because reading your question you seem to be lost.
docker containers mainly have the idea of "one service per container", but of course there are ways to run multiple inside one. As a tip, read this first: https://docs.docker.com/engine/examples/running_ssh_service
I also had to read much more of the first chapters of the documentation until it boiled down how to think about a container.
