Deployment of Nubus on Kubernetes

More about running on Kubernetes

Install Nubus on an existing Kubernetes cluster. With the provided Helm charts, installation and future upgrades are fully automated.

Univention provides all necessary artifacts for deployment on Kubernetes (container images and Helm chart) in a Harbor registry. The download is therefore managed directly through Kubernetes as part of the documented setup. All required steps are detailed in the linked “Operations Manual.“

Download UCS Source Code

The source code of each UCS release is also available. This can be downloaded in packages via the “apt-get source” mechanism built into APT. This applies to both in-house developments and software adopted by Debian. The packages are subject to different licenses. These are documented within each package.

The source code of the in-house developments is also available in a GIT repository. It is also possible to participate in the further development of UCS.
