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.

Can I use "FROM ubuntu@sha256:e2ff67c8f9bb7e1eda3ec573fd8ac74b976d170d9e13babc5c5035f4443af744" to build a image base on ubuntu:trusty? It seems like the digest of trusty is "sha256:e2ff67c8f9bb7e1eda3ec573fd8ac74b976d170d9e13babc5c5035f4443af744"

@thaniyarasu these are containers, not VMs, so the kernel is provided by the host.

is this ubuntu image updated to linux kernel 3.19.* ?
my host is ubuntu 14.10 with kernel is 3.16.0-34-generic
today i did
docker pull ubuntu:15.04
docker run -i -t ubuntu:15.04 /bin/bash
root@sdf34rdsf:~$ uname -a

but says that they have upgraded kernel version to 3.19.*
is this "official ubuntu image" updated one ?
should i update my host os from ubuntu 14.10 to 15.04 ?
