KDE neon on Docker

Do you want to test KDE applications from master without installing KDE neon Dev Unstable edition. Maybe you have Dev Unstable edition installed but want to develop on your stable branch. Maybe you like your larswm setup but wonder if Plasma is the desktop for you and are looking for an easy way to test it out. KDE neon Docker images are the solution to quickly give you access to use or develop another branch without reinstalling your system or spending hours compiling.

32111280196_9b2875a809_b.jpg The above screenshot shows a computer running its normal Plasma desktop with three KDE neon Docker containers. One is a full Plasma session of KDE neon User Edition, one is a full Plasma session of KDE neon Developer Unstable edition and one is a single app from Developer Stable edition running Okular.

KDE neon Docker Images comes in two variants each with the same Plasma editions as our archives. Plasma images (~2GB) come with the same software as our installable ISOs, Plasma and minimal applications. All Applications images (~4GB) come with all applications built on KDE neon.

Flavours available are: kdeneon/plasma:dev-unstable, kdeneon/plasma:dev-stable, kdeneon/plasma:user, kdeneon/plasma:user-lts (and the same for kdeneon/all)

To give it a try first set up Docker as you would for your distro. For Ubuntu distros that means running:

apt-get install docker.io xserver-xephyr
sudo usermod -aG docker $(whoami)

and log out and in again

By default it will run a full session with startkde on DISPLAY=:1, you can use Xephyr as an X server window.

Xephyr -screen 1024x768 :1 &
docker run -v /tmp/.X11-unix:/tmp/.X11-unix kdeneon/plasma:dev-unstable)

Or you can tell it to run on DISPLAY=:0 and run a single app

xhost +
docker run -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=:0 kdeneon/plasma:dev-unstable

For an interactive session where you mount your coding directory ~/src run

xhost +
docker run -ti -v /tmp/.X11-unix:/tmp/.X11-unix -v ~/src:/home/neon/src -e DISPLAY=:0 kdeneon/plasma:dev-unstable bash

This will give you a Bash prompt, you can code as you would on your host machine and run X apps. Type exit to quit, the ~/src directory will be preserved on your host machine.

You can also commit your Docker images if you make changes you would like to come back to such as installing applications. For more information on using Docker see Docker Engine user guide.
