Ubuntu Desktop (GNOME) Dockerfile

This repository contains the Dockerfile and associated files for setting up a container with Ubuntu, GNOME and TigerVNC for Docker.

• The VNC Server currently defaults to 1366*768 24bit.

Dependencies

• dockerfile/ubuntu

Installation

1. Install Docker.

   For an Ubuntu 14.04 host the following commands will get you up and running:

   `sudo apt-get -y update && \

   sudo apt-get -y install docker.io && \

   sudo ln -sf /usr/bin/docker.io /usr/local/bin/docker && \

   sudo restart docker.io`

2. You can then pull the file:

   sudo docker pull cannycomputing/dockerfile-ubuntu-gnome

   Or alternatively build an image from the Dockerfile:

   sudo docker build -t="cannycomputing/dockerfile-ubuntu-gnome" github.com/CannyComputing/Dockerfile-Ubuntu-Gnome

SuperQuick Install

This will get you going superfast - one line! - from a fresh Ubuntu install (rememebr to update the /etc/hosts file to relect your hostname at 127.0.1.1)

sudo apt-get -y update && \
sudo apt-get -y install docker.io && \
sudo ln -sf /usr/bin/docker.io /usr/local/bin/docker && \
sudo restart docker.io && \
sudo docker pull cannycomputing/dockerfile-ubuntu-gnome && \
sudo docker run -it --rm -p 5901:5901 cannycomputing/dockerfile-ubuntu-gnome

Usage

Starting

• Change the port number to run multiple instances on the same host (remeber to open the ports for tcp ingress)

• this will run and drop you into a session:

  sudo docker run -it --rm -p 5901:5901 cannycomputing/dockerfile-ubuntu-gnome

• or for silent running:

  sudo docker run -it -d -p 5901:5901 cannycomputing/dockerfile-ubuntu-gnome

Connecting to instance

• Connect to vnc://<host>:5901 via your VNC client. currently the password is hardcoded to "acoman"

Notes

• You can use the following command from within the container to kill the vnc server:

  USER=root vncserver -kill :1

• Then run the following command from within the container to restart start the vnc server, the flags are optional but pretty self explanatory.

  USER=root vncserver :1 -geometry 1024x768 -depth 24
