Official Docker image for Ubuntu Server?
The question was about Ubuntu Server, but all the answers and discussions were about Ubuntu Desktop. So I'll answer both but address Ubuntu Desktop first. Finally, (and not really recommended for an ephemeral container which most containers should be per Docker's best practices, but hey, there's exceptions) you can install Ubuntu Desktop and Ubuntu Server on a container and run it.
NOTE: You can add the --rm
flag to keep your host's storage from bloating by automatically deleting containers after they run if you're only experimenting with them.
docker run --rm -it ubuntu
Ubuntu Desktop Container
A running container
This is a pretty big container! ~ 1.5Gb
If you run:
docker run -it ubuntu
Then, in the container:
> apt-get update && apt-get install -y ubuntu-desktop
You'll effectively download the Ubuntu Desktop
Dockerfile for Ubuntu Desktop
A Dockerfile could be made:
FROM ubuntu:16.04
ENV DEBIAN_FRONTEND noninteractive
RUN apt-get update && apt-get install -y ubuntu-desktop
Then build it:
docker build -t ubuntu-desktop .
And run it:
docker run -it ubuntu-desktop
Ubuntu Server container
A running container
docker run -it ubuntu
From container terminal:
apt-get update && apt-get install -y ubuntu-server
Dockerfile for Ubuntu Server
FROM ubuntu:16.04
ENV DEBIAN_FRONTEND noninteractive
RUN apt-get update && apt-get install -y ubuntu-server
Build it:
docker build -t ubuntu-server .
Run it:
docker run -it ubuntu-server
Ubuntu Desktop and Server Container
A running container:
docker run -it ubuntu
The container's terminal:
apt-get update && apt-get install -y ubuntu-server ubuntu-desktop
Dockerfile for Ubuntu Server/Desktop
FROM ubuntu:16.04
ENV DEBIAN_FRONTEND noninteractive
RUN apt-get update && apt-get install -y ubuntu-server ubuntu-desktop
Build it:
docker build -t ubuntu-server-desktop .
Run it:
docker run -it ubuntu-server-desktop
You can test it, first run bash in Ubuntu container by:
docker run -it ubuntu /bin/bash
-i
,--interactive
Keep STDIN open even if not attached
-t
,--tty
Allocate a pseudo-TTY
Then run following command to check if ubuntu-desktop
is installed:
dpkg -l ubuntu-desktop
All I could find is an official Docker image for Ubuntu Desktop on Docker Hub.
Nowhere does that page say that it's an Ubuntu Desktop image. Anyway, that wouldn't make sense because you (generally) don't run a desktop environment in a Docker container.
