Build a full Ubuntu desktop docker image

问题:

I want to build a full version of Ubuntu 14 desktop as the base image for gui applications, I know how to build on the Ubuntu desktop version by the debootstrap, as described in https://docs.docker.com/articles/baseimages/, but that is a minimal Linux version and some GUI application cannot run perfectly, because there are some basic components missing, such as a font family, so I want the full control of a basic image, thanks!

I don't see the benefits of it, but impossible n'est pas français (impossible isn't French).

Docker Desktop is a way that will give you an X11 server to connect on using SSH.

This Dockerfile creates a docker image and once it's executed it creates a container that runs X11 and SSH services. The ssh is used to forward X11 and provide you encrypted data communication between the docker container and your local machine.

https://github.com/fcwu/docker-ubuntu-vnc-desktop provides a convenient setup:

docker run --name ub16vnc -p 6080:80 -p 5900:5900 dorowu/ubuntu-desktop-lxde-vnc

Then either:

• visit: http://127.0.0.1:6080/#/ which runs a noVNC more limited JavaScript VNC client

• run:

  sudo apt-get install tigervnc-viewer
  xtigervncviewer :5900
  

  Then inside vinagre, you might want to go into full screen mode to be able to see the full desktop

  I also tried vinagre, but it was much laggier when scrolling Firefox on YouTube.

To quit just kill docker on the terminal. And to restart the machine

docker start ub16vnc

and then reconnect with VNC. Then to quit the machine:

docker stop ub16vnc

You have to wait a few seconds for the VNC server on the guest to start before you can connect.

Chromium won't start from the menu. If you try to launch it from the command line it explains why:

Running as root without --no-sandbox is not supported. See https://crbug.com/638180.

Firefox does not care however.
