Multi Container Support for Docker Apps for Univention App Center

docker-logo-blog-header

Since the release of UCS 4.1 in November 2015, the App Center has supported Docker apps. These are applications in the form of Docker images that are deployed by the App Center in a Docker container. To do this, the App Center downloads the Docker image of an app and starts the Docker container. We call these apps “Single Container Apps” because the App Center only supports one container per app. This functionality is sufficient for many apps.

Until now!

In the Univention App Center: OpenID Connect Provider

OpenID Connect Provider-01-01

With the development of the OpenID Connect Provider App, which we announced at the Univention Summit 2018, we have taken another important step towards making UCS a secure and open platform for managing a wide range of services.

The goal we are pursuing: All UCS users should retain full control over their data and digital identities at all times. Also they should have the greatest possible and free choice between different software applications.

News from The Univention Development Team

It‘s been only four weeks that we published UCS 4.3-2, and we already have some more news for you from our development team.

UCS 4.2-5

Two weeks ago we published UCS 4.2-5. Essentially this release bundles the nearly 100 errata updates, mainly security updates and stabilizations that were released for UCS 4.2-4. The upcoming errata updates for UCS 4.2-5 will only be available for customers with an enterprise subscription. If you are a Core Edition user, we therefore recommend you to update to UCS 4.3 so that you continue to receive security updates in the future.

With UCS 4.3-2, the second point release for Univention Corporate Server (UCS) 4.3 is now available, which includes a number of security updates and various new features.

New: UCS maintenance mode

UCS 4.3-2 now offers a maintenance mode for importing release updates via Univention Management Console (UMC). UMC is the web-based, graphical user interface for the administration of the entire domain. In the past, when a release update was recorded, short-term failures of the UMC could occur, for example, because the updated services were restarted.

New: UCS Dashboard Facilitates Administrator Monitoring

In the UCS Dashboard app, we now have the first (beta) version of a new dashboard based on the Open Source solutions Grafana® and Prometheus. The app allows administrators to check the status of domains and individual servers on different dashboards quickly and simply. The dashboards can be accessed simply via a web browser, access a database in the background, and deliver updated reports on certain aspects of the domain or servers continually.

Briefly : Set Up a UCS Mail Server as a Central IT Service

Graphic about UCS and mail server
Learn in this article how to set up a fully functional mail server. As e-mails are today an essential part of business communication, we recommend to embed the mail server as a central service into the IT of your organization.

Let me show you here not only how to do this but also explain the various options for receiving and sending mails. In addition, I will describe how to configure the users.

How UCS synchronizes Linux/Windows IT Infrastructures with Samba AD

The central management of a heterogeneous network has always been UCS’ strength. This was our goal from the beginning to provide a platform that bridges the Linux/Windows worlds. But how does the synchronization between UCS and Microsoft Windows actually work? The problem is that Windows doesn’t speak the same language as UCS. They don’t support the standard-compliant LDAP protocol that allows the communication between the server and clients in UCS. Microsoft has chosen a different approach for its Active Directory.

Let me explain you today which exact technologies we introduced in Univention Corporate Server to provide a solution to this problem. Among other things, I give you details about the replication process via listener/notifier for OpenLDAP, DRS replication for the Active Directory and the Univention S4 Connector, which synchronizes between Microsoft Windows and Linux.

Release of UCS 4.3-1: Various Security Updates and Usability Improvements

We released UCS 4.3-1, the first point release for Univention Corporate Server (UCS) 4.3. In addition to a number of security updates, it also brings various new features.

The diagnostics module of the Univention Management Console (UMC), for example, now provides further functional tests. These help administrators to check the “health” of the server and the entire domain. In addition, UCS 4.3-1 has improved its usability, for example with regard to the configuration of e-mail addresses or DNS settings. Furthermore, the integration of very large LDAP scheme extensions and the start of the LDAP server on DC backup and DC slave systems now work much more stable.
