Univention Bugzilla – Bug 39870
Produce "official" Docker appliance images
Last modified: 2019-01-03 07:22:57 CET
Docker offers a build service which pulls a Dockerfile from github. If it follows certain guidelines the image is supposed to be advertised as "official" on hub.docker.com. This might be a good way to advertise UCS as an appliance and we should aim at getting the images currently available on https://hub.docker.com/u/univention/ into that status.
The Dockerfile and scripts used to build the ucs-stem-amd64 image are already committed into ucs-4.1/internal/univention-docker-dev. They should be commited to github in a way that is accepted for official Docker image builds.
Additionally the scripts for building ucs-generic-amd64:4.1-0 and ucs-master-amd64:4.1-0 and the other role images should be integrated into a Dockerfile following the example of ucs-stem-amd64 and uploaded.

We should create UCS 4.1 docker images and upload them to the docker hub.
is there a chance to please get the dockerfiles and possible installation scripts to reproduce, how a container-installation works?
I aim to install UCS in an LXC-Container, which does not work starting with an wheezy container.
Sorry, the link I posted is not usable, I'll think about a way to make the scripts and Dockerfiles available.
Same requirement here. I would like to run UCS in an LXC container too.
Are there any dockerfiles, howtos, guides, checklists or notes, that would help someone, who is experienced in debian/ubuntu server administration?
We have a Debian source package containing the scripts and Dockerfile templates.
On a UCS 4.1-4 system this can be installed simply by running the following two commands:
ucr set repository/online/unmaintained='yes'
You can also directly download the package from
With the files installed to /usr/share/univention-docker-dev:
1. A debootstrapped UCS "minbase" image can be created with:
2. Building on that, a "stem" image can be created, containing files common to all UCS server roles:
3. Building on that "stem" image, either a "generic" or a specific role image can be created, e.g. a master:
The result should be exactly what https://hub.docker.com/u/univention/ provides.

Thanks. This helps a lot.
