Foreman Birthday Event 2024 – Recap
On Monday, 15.07.2024, I met early with my colleagues Lennart and Matthias to travel to Garching for the Foreman Birthday Event. This year it was again hosted by ATIX at a conference room next to their office, so thanks to all of them for having as there, especially to Bernhard! And also thanks to the community members that joined us! It was a nice mix from the German community with also some international guests from Red Hat, mostly familiar faces but also some new ones. And it is as great to see the community still growing even after 15 years as it is great to meet all the people who became friends in this time.
The morning
After some time to get together we entered the room and Bernhard gave the official welcome before handing over to his colleagues for the first talk.
“Automated Provisioning with SecureBoot and Foreman” by Jan Löser and Markus Reisner was a great talk giving insights in SecureBoot in general as a start. Then they showed the current state of Foreman handling SecureBoot and why the implementation is limiting real world scenarios. But ATIX is working on a complete overhaul of the feature and thanks to the community input it is taking shape. The new feature will be backwards compatible, so no change needed if you do not want to use it. This is great, especially as the first step will require some manual work to setup everything. But the plans for automated setup are there and as I know the guys it will not take too long to get this implemented, too. With this in place using SecureBoot with Foreman will give you a better experience!
As second speaker Martin Alfke told us the story “How Foreman Community enables new contributors”. While working with Foreman already for a long time at different customers, he never joined the community in a deeper sense. After they developed Hiera Data Manager customers asked for some integration with Foreman. And with the help of the community they delivered! So now you can debug the Hiera data of your Puppet environment not only much easier, but also directly from the Foreman UI.
On the day Martin got the help with the last missing piece, the Foreman installer, and was encourage to join official Professional Services starting with a blogpost.
After a short break Evgeni Golov introduced the audience to “Foreman build test environment: migration from Jenkins to GitHub Actions”. He showed where the Project was before starting the migration, the current stage and what else is planned. He also encouraged the Plugin developers in the room to make use of it. And I think other projects can also learn from it. So take a look at his slides.
The afternoon
ATIX invited us to have lunch in the restaurant of the office complex which provided some nice choices and great quality of food. I also used this for a nice mixture of private and business talk with Martin and some ATIX guys. It is always great to realize how well we work together in the community even we are somehow competitors.
Then the stage was mine asking the question “Foreman – a complete lifecycle management tool for desktops?”. A bit out of my comfort zone it was not a technical deep talk with many demos, but a more light one sharing my experience based on some use cases. Starting with a simple virtual desktop over our training setup to the proof of concept we did for a customer project I looked into the challenges we experienced and how we solved them if we did already. After that I came to the conclusion that Foreman is ready to manage Linux desktops with only a bit of work, but the Linux desktops are not ready to be automated without putting some more work into.
“Foreman documentation: Helping users figure things out since May 15, 2019” by Maximilian Kolb and Aneta Šteflová Petrová talked us through the progress the Foreman documentation made since Red Hat started to upstream the documentation. The anecdotes and examples given by the two technical writers showed their great commitment to the project. One reason they pointed out why the project is seen as a real success story is how closely developers and technical writers of different companies involved work together.
Afterwards we had a short discussion on how to improve further and how to reach the goal of the new documentation being the default one.
And last but not least Ian Ballou joined us remotely from the US to show “New Feature: Pushing Containers Into Katello”. It was great having him give this demo even without being on-site. He did really dived deep into this new feature and answered all the questions the audience had afterwards. So if you had a Container registry to push your images to and then to be synced from to Katello, this will make your life easier by allowing direct push to Katello’s registry.
Cake time
After the talks and a short feedback round unfortunately some had to leave, but for the rest of us it was cake time. Bernhard hesitated to cut the cake, so this job become my honor. After a quick count I had to cut it into 20 pieces directly starting the discussion how to do this best with everyone offering suggestions. But with the problem solved, we split into groups. Some still discussing topics from the talks, some talking about other aspects of the project or IT in general and others just having a friendly chat. About one hour later it was time to leave so we could catch our train back to Nuremberg, but we were not the last ones.
It was again a great event, so thanks to everyone who made it possible. I already heard the feedback like having an introduction round, having more hands-on demos, more time for open discussion, more hybrid. Not sure what of this we can implement next year, but I want to make it a similar success again in 2025!
Other celebrations
But we were not the only one celebrating the Foreman’s 15th birthday. Christian Stankowic made a special on the podcast FOCUS ON: LINUX consisting of two episodes. Episode 110 is “15 Jahre Foreman” (in German) which has Christian, Evgeni, Bernhard and me talking about the project and trying to include every possible pun. Episode 111 is an Interview with Ohad Levy about the project’s history and answering questions.
P.S.: As a side note for Ian: I promised to eat a slice of the birthday cake in your name so the second piece was also delicious and replaced my diner! 😉

OSCamp 2024 | Confidential Containers – Sensible Daten und Privatsphäre in Cloud Native Umgebungen
Am OSCamp 2024 nahm uns Magnus Kulke mit in die Welt der Confidential Containers und wie sensible Daten und Privatsphäre in Cloud Umgebungen gewahrt werden können.
Warum Confidential Containers?
Magnus hat uns in seinen Vortrag an anschaulichen Beispielen erklärt, warum Confidential Containers gerade in Cloud Umgebungen wichtig sind. Insbesondere bei der Verarbeitung von PII-Daten.
Er geht darauf ein, was die problematischen Stellen sind und was es zu beachten gilt. Angefangen von der Bereitstellung der Umgebung über den Betrieb, da die Daten für den Host im laufenden Betrieb stets Transparent sind.
Eine Bereitstellung der entsprechenden Umgebung ist nicht trivial und erfordert einiges an Vorarbeit. Die Hoffnung besteht darin, dass sich Confidential Computing verbreitet, wenn es in die Container Umgebungen einfügt wird.
Konzepte
Nachdem wir wissen, warum wir Confidential Containers benötigen, bringt uns Magnus die aktuellen Konzepte näher, welche Möglichkeiten es zur Realisierung gibt, was wichtig ist und was es braucht, damit es als erfolgreich umgesetzt gilt.
Demo
Zur Abrundung des Vortrags gibt es noch eine Demo wie Confidential Containers umgesetzt werden kann und betrieben.
Magnus erklärt die Root of Trust von der Hardware bis zur Software anhand eines etablierten Konzepts.
Eine Live-Demo mit Kata Containers hat sich Magnus nicht nehmen lassen.
Zusammenfassung
Magnus gibt eine Einführung, einen Überblick von den Grundlagen über Konzepte samt Demo auf dem Themenfeld der Confidentail Containers.
Er stellt das Kata Containers Projekt vor und gibt eine praktische Live Demo zur Abrundung des Vortrags.
Confidential Containers im Confidential Computing Umfeld wird immer wichtiger bei der Verarbeitung von personenbezogenen Daten und bleibt ein spannendes Thema.
OSMC 2024 | Workshop Update!
Earlier, we announced the first set of workshops for this year’s Open Source Monitoring Conference. Now, we’re excited to announce two additional workshop topics that will be available on November 19.
OpenTelemetry Fundamentals
This workshop, held by Markus Opolka, focuses on OpenTelemetry, a vendor-neutral open-source observability framework for instrumenting, generating, collecting, and exporting telemetry data such as traces, metrics, and logs. Since its inception, it has rapidly gained adoption by industry leaders in the observability space.
In this workshop, you will delve into the core concepts and the ecosystem of OpenTelemetry. There will be hands-on demonstrations and small sessions where you will transition from theory to practice. The goal is to gradually build a functioning system instrumented with OpenTelemetry. Participants are required to have basic knowledge of Linux and very rudimentary programming skills.
Discover all the details about Markus’ OpenTelemetry workshop!
Developing Icinga Web 2 Modules
Learn from Nicolas Schneider how to extend Icinga Web 2 and its modules. You’ll become familiar with the basic structure of a module and understand common pitfalls. From there, the workshop will focus on your specific needs. What’s missing in your monitoring environment? Do you need to implement missing CLI actions? Would you like to provide user documentation within Icinga Web 2? Are you missing a previously removed feature? Let’s optimize monitoring together and deliver the specific features your environment requires.
Attendee Requirements: Participants should be proficient in at least one scripting language. PHP knowledge and a basic understanding of HTML and CSS would be great.
Get the scoop on Nicolas’ Icinga workshop!

NETWAYS stellt sich vor – Kleon Rockenbach
Name: Kleon Rockenbach
Alter: 29
Position bei NETWAYS: Systems Engineer
Bei NETWAYS seit: April 2024
Was genau gehört zu Deinem Aufgabenbereich bei NETWAYS?
Als Teil des MyEngineer-Teams bin ich aktuell für den First-Level-Support unserer Kunden zuständig. Das heißt, ich stehe von der ersten Kontaktaufnahme bis hin zur Eskalation dem Cloud-Spezialisten zur Verfügung. Darüber hinaus bin ich dafür verantwortlich, die Funktionsfähigkeit der Instanzen unserer Kunden mithilfe unseres Icinga-Monitorings zu gewährleisten. Dazu gehört, potenzielle Probleme schnell, nachhaltig und effektiv zu lösen. Die Entwicklung von Tools, die uns bei diesen Aufgaben unterstützen, ist ebenfalls Teil meiner Aufgaben im Team.
Was macht Dir an Deiner Arbeit am meisten Spaß?
Es mag ja klischeehaft klingen, aber es ist die Abwechslung, immer wieder vor neuen Herausforderungen zu stehen und diese mit einer guten Mischung aus Kreativität und Fachwissen zu lösen. Ach, der Kaffee im Office ist auch herrlich und immer ein Highlight. Es gibt wohl keinen ITler, der kein bisschen Koffein braucht, oder?
Welche größeren, besonders interessanten Projekte stehen künftig an?
Momentan steht nichts Großes an. Seit ein paar Wochen arbeite ich zwischendurch mit Kollegen aus dem MyEngineer- und Cloud-Team an einem automatischen Bereinigungstool für unsere OpenStack Instanzen. Dieses erkennt Wartungs-Snapshots und dann bereinigt sie, sobald die Datenpersistenz dieser Backups nicht mehr benötigt wird. Dafür haben wir unter anderem angepasste Authentifizierungsverfahren für das Tool entwickelt.
Was machst Du, wenn Du mal nicht bei NETWAYS bist?
Neben den üblichen Stunden am PC, in denen ich gerne mit Freunden zocke oder privat Software und Arduino zu Testzwecken aufbaue, bin ich im Sommer gerne draußen beim Trail-Mountainbiking und Wandern. Wenn der Winter aufschlägt, mache ich mich mit dem Snowboard auf den Weg in die Berge. Ein paar Mal pro Woche trainiere ich auch gerne Brazilian Jiu-Jitsu.
Wie geht es in Zukunft bei Dir weiter?
Ich habe eine Leidenschaft für IT, insbesondere neulich entdeckt im Bereich Cybersecurity und DevSecOps. Mein Ziel ist es, mein Wissen und meine technischen Fähigkeiten weiter auszubauen, um in Zukunft größere Projekte erfolgreich leiten zu können sowie Lösungen für Threat-Intelligence und Vulnerability Überwachung zu implementieren. Ich bin überzeugt, dass ich bei NETWAYS eine top Gelegenheit gefunden habe, um dieses Ziel zu erreichen.
