Meet our Experts

Running Kubernetes at scale, meeting security and compliance requirements, and deploying Kubernetes clusters spanning on-premise or multiple public clouds can introduce an increasing amount of complexity. Request a meeting with our Founders or experts onsite to discover how to easily master all these challenges and drive your business forward!

    Comms & Social Media - Why Does a Project Need It

    Mario Fahlandt, Customer Delivery Architect at Kubermatic with Chris Short (Amazon Web Services)
    3:20 PM BST at Maintainer Summit Europe 2025

    All the projects have at least a website. Most of the projects try to have some kind of Social Media presence. However, let's face the hard truth - Comms for a project is hard, and we can run into various pitfalls, and it is a lot of ground to cover.

    Let's discover what channels and processes you can employ in a project to ensure good communications. We start with the identification of target groups for comms. What channels to use and will end in drafting social media policies and guidelines for the contributors when they are publishing comms in the name of a project. Also, have you ever thought of critical comms for a project - how do you handle comms if something critical is happening? After the session, you have ideas for your project to move towards a more consistent and reliable communication.

    Building a Cloud Native Curriculum for Real-World Readiness

    Marko Mudrinić, Senior Software Engineer at Kubermatic
    03:55 PM BST at Cloud Native University

    As Cloud Native technologies become the backbone of modern industry, it's important to prepare computer science students for the challenges and expectations they'll face in their careers. Traditional curricula often focus on small, theoretical projects and assignments, while the real world is more about working on large-scale projects, collaborating with diverse teams, and utilizing concepts such as DevOps, none of which students had prior contact with.

    Marko was part of the team building a Cloud Native curriculum focused on DevOps, Kubernetes, CI/CD, and open source for a 13-week course. The team quickly ran into problems, such as designing assignments big enough to cover these concepts practically. They also discovered that students were not well-versed in Linux, Bash, and working with the CLI. But 13 weeks is a little time to teach all of that. Marko will share how they overcame these problems, and created a course that received very positive feedback from 300+ students.

    Tutorial: Exploring Multi-Tenant Kubernetes APIs and Controllers With Kcp

    Marko Mudrinić, Senior Software Engineer at Kubermatic with Robert Vasek (Clyso GmbH), Nabarun Pal (Broadcom), Varsha Narsing (Red Hat) & Mangirdas Judeikis (Cast AI).

    While Kubernetes transformed container orchestration, creating multi-tenant platforms remains a significant challenge. kcp goes beyond DevOps and workload management, to reimagine how we deliver true SaaS experiences for platform engineers. Think workspaces and multi-tenancy, not namespaces in a singular cluster. Think sharding and horizontal scaling, not overly large and hard to maintain deployments. With novel approaches to well-established building blocks in Kubernetes API-Machinery, this CNCF sandbox project gives engineers a framework to host and consume any kind of API they need to support their platforms.

    In this hands-on workshop, participants will learn how to extend Kubernetes with KCP, build APIs, and design controllers to tackle multi-tenancy challenges. By exploring real-world scenarios like DBaaS across clusters, attendees will gain practical skills to create scalable, multi-tenant platforms for their Kubernetes environments.

    Dynamic Multi-Cluster Controllers With Controller-runtime

    Marvin Beckers, Team Lead at Kubermatic with Stefan Schimanski (Upbound)
    3:00 PM BST at KubeCon + CloudNativeCon

    controller-runtime is the most popular SDK to write controllers for individual Kubernetes clusters. But the Kubernetes landscape is changing quickly: multi-cluster is becoming ubiquitous (e.g. through Cluster API), with clusters joining and leaving dynamically. controller-runtime has had no direct support, making writing uniform multi-cluster controllers hard and fracturing the emerging ecosystem.

    This talk explores how to build controllers that reconcile resources across a dynamic fleet of Kubernetes clusters. A key change is the ability to plug in a dynamic cluster provider that registers new Kubernetes clusters from a specific source. While implementation internals are briefly discussed, focus is on a hands-on walkthrough for writing your own cluster provider, event handlers and reconciler functions.

    We discuss a simplistic cluster provider implementation for "kind" clusters as an example and extrapolate from that how more complex providers could look like (e.g. for CAPI or kcp).

    Navigating the Inevitable: Kubernetes Breaking Changes Behind the Scenes

    Marko Mudrinić, Senior Software Engineer at Kubermatic
    4:00 PM BST at KubeCon + CloudNativeCon

    You're looking forward to a new feature, waiting for the release day like it's Christmas morning. Suddenly, the feature is dropped from the release. Even worse, a feature you heavily depend on is unexpectedly deprecated or removed. What now? Negative emotions take over, you feel sad, frustrated, and even angry at the project and its maintainers. Fortunately, this doesn't happen too often. But it does happen.

    The Kubernetes maintainers strive to make users satisfied, but they also have to prioritize the health of the project and the well-being of the maintainers. To do that, they sometimes have to make breaking changes, even on short notice, as hard as it might be. In this talk, we'll dive into some of those decisions, see what went on behind the scenes, and talk a bit about Kubernetes policies. Finally, we'll explore your options as an end user, how you can be better informed, how you can provide feedback on proposed changes, and how you can help the project!

    Contributing To Kubernetes in Its Second Decade - How ContribEx Enhances the Journey!

    Mario Fahlandt, Customer Delivery Architect at Kubermatic with Nabarun Pal (Broadcom), Madhav Jivrajan (UIUC), Priyanka Saggu (SUSE)
    11:45 AM BST at KubeCon + CloudNativeCon

    SIG Contributor Experience has been wildly successful in helping grow the contributor base of Kubernetes in the first ten years of the project via New Contributor Workshops. We stressed on the importance of growing existing contributors in our last maintainer track session. However, the other side of the sustainability coin is ensuring that contributors who get started with contributing to Kubernetes, actually stick around. A lot has changed in the last decade, and we also need to change how we teach folks to contribute and interact with the community. Join us as we give a comprehensive overview of the Kubernetes governance and community structure, where you can seek help and what some pitfalls are that you will unexpectedly but inadvertently face in your contributor journey. We will highlight areas that are suited for folks from all backgrounds: marketing, content creation, event planning, community elections, automation and so much more!
