    #117 How Policy as Code Is Changing Kubernetes Forever

    In this episode of De Nederlandse Kubernetes Podcast, we talk with Jim Bugwadia, founder and CEO of Nirmata, and Shuting Zhao, Staff Engineer and one of the maintainers of Kyverno — the CNCF project for Kubernetes policy management. Jim and Shuting share how Kyverno was born from Nirmata’s commercial work and has since become one of the most widely adopted open source projects in Kubernetes governance, with over 3.4 billion image pulls. We explore the real question: Why does Kubernetes need policies if it’s already declarative?  Jim explains how policy as code helps developers, operators, and security teams collaborate on cluster configuration at scale — from pod security to resource quotas, network policies, and automation. Shuting dives deeper into how Kyverno enables granular control, policy exceptions, and flexible enforcement modes — from audit to enforce. They discuss how large organizations use policy automation to improve compliance, security, and even cost efficiency, citing use cases like Adidas saving 50% in dev/test environments using policy-driven resource management. We also touch on: 🧠 The evolution of policy as code and its parallels with infrastructure as code (like Terraform)🧩 The role of AI in simplifying policy authoring (“I don’t want to run as root — just write the policy for me”)⚙️ Nirmata’s Control Hub, a collaboration layer for DevSecOps teams🔒 Shift-down security, where platform teams integrate security directly into Kubernetes itselfA deep-dive episode into how Kyverno and Nirmata are shaping the future of secure, automated Kubernetes governance — blending open source, AI, and DevSecOps collaboration.

    #116 Running AI on Kubernetes: From GPUs to CRO

    In this episode of De Nederlandse Kubernetes Podcast, we talk with Carlos Santana, Principal Partner Solution Architect at AWS and long-time contributor to the Kubernetes and AI communities. Carlos joins us to explore what it really takes to run AI workloads on Kubernetes, from GPU scheduling to scaling inference and training efficiently across clusters. We discuss how AI and machine learning are transforming the cloud-native ecosystem — and why orchestration is becoming just as important as the models themselves. He shares insights into: 💡 The challenges of scheduling and sharing GPUs in multi-tenant Kubernetes clusters⚙️ Why Kubernetes Resource Orchestrator (CRO) could be the next big abstraction layer🚀 The balance between performance, cost efficiency, and developer experience🧠 His hands-on experiments with Jetson devices, edge computing, and model optimization🌐 How open source projects and cloud providers are shaping the future of AI infrastructureA forward-looking conversation about where AI, Kubernetes, and cloud-native engineering are heading — from someone building that future at scale.

    #115 Extending Kubernetes: CRDs, Inheritance & Modularity

    In this episode of De Nederlandse Kubernetes Podcast, we talk with Mustafa Hadadian, PhD researcher at the University of Groningen and founder of startup CAIDEL. Mustafa shares his journey from video game development to big data and Kubernetes innovation, and how his latest work explores a powerful concept: bringing inheritance into Kubernetes Custom Resource Definitions (CRDs). We dive into his poster presentation at KubeCon, titled “Extensible Kubernetes CRDs via Inheritance for Modularity and Reuse”, and discuss: 🔧 How CRDs can be extended — just like classes in Java — to reduce duplication and improve reusability. 🧩 Why inheritance could make Kubernetes development more modular and flexible. 🚀 How this helps developers define what they need (e.g., “a message queue”) while platform engineers decide how it’s implemented (Kafka, RabbitMQ, etc.). 💡 The proof of concept he built with his student Nick — showing how inheritance could work in practice through annotations and controllers. 🤖 And how his broader PhD project explores AI-driven data pipelines that assemble themselves automatically based on goals and inputs. A fascinating deep dive into what’s next for CRDs, extensibility, and how academia and open source innovation intersect in the Kubernetes world. Stuur ons een bericht.

    #114 Do We Even Need Logs Anymore? And What is vCluster?

    In this episode, we sit down with Nicolas Fränkel, Developer Advocate at Loft Labs, to talk about two things every Cloud Native engineer should know in 2025: 🪵 OpenTelemetry Tracing and 🌀 vCluster. Nicolas helps us unpack why tracing is often the missing pillar of observability — and whether it might one day make traditional logs obsolete. We dive into: How traces, spans and sampling actually work under the hood.Why post-sampling may save your storage bill.What happens when you combine tracing with frameworks like Java, Go and Rust.And yes… how to finally understand those span IDs 😅Then we switch gears to vCluster — Loft Labs’ open-source project that lets you run full virtual Kubernetes clusters inside another cluster. Think of it as: 👉 faster developer environments 👉 lightweight isolation for CI/CD 👉 no more waiting 15 minutes for test clusters to spin up Whether you care about observability, cost-efficient clusters, or simply love smart engineering, this one’s packed with insights and stories from the field.

    #113 Goodbye Ingress-NGINX Hello Gateway API!

    In this episode we sit down with James Strong, Solutions Architect at Isovalent (the team behind Cilium), to talk about one of the biggest evolutions in Kubernetes networking: the shift from Ingress-NGINX to the Gateway API. James, who is also a maintainer of Ingress-NGINX, explains why the project is being phased out and how the community is building its successor — in-gate, a new implementation designed around the Gateway API. We dive into: Why the Gateway API is the next-generation replacement for Ingress.The challenges of migrating existing workloads and dealing with technical debt.How the new API improves security, RBAC separation, and flexibility.The importance of community contribution, not just through code, but by joining discussions, testing, and providing feedback.We also discuss common misconceptions, unusual use cases (like people trying to load balance VPNs and SFTP!), and what the future looks like for networking projects in the CNCF ecosystem. An honest, behind-the-scenes look at the future of Kubernetes networking — from someone helping to build it. Stuur ons een bericht.

    #111 Beyond Orchestration: CNCF’s Past, Present and Future

    In this 11th episode of the 100th-episode series, we speak with Chris Aniszczyk, CTO at the Cloud Native Computing Foundation and the Linux Foundation. He reflects on ten years of CNCF and explains how the community has continually adapted to the needs of its users: from the arrival of Prometheus and containerd, to GitOps tools like Flux and Argo, and the rise of OpenTelemetry as the standard for observability. Chris explains that Kubernetes is much more than just a container orchestrator. Thanks to extensions and CRDs, it is increasingly seen as the “Linux of the cloud” — a generic infrastructure layer on which you can run not only containers but also VMs, databases, and even AI workloads. We discuss the challenges around stateful workloads, the role of projects like Vitess and CloudNativePG, and how Kubernetes is maturing in supporting complex scenarios. We also touch on the future: serverless patterns, better resource optimization, and the growing interconnection between cloud native and AI. --------- In deze 11e aflevering in de 100e aflevering-reeks spreken we met Chris Aniszczyk, CTO bij de Cloud Native Computing Foundation en de Linux Foundation. Hij blikt terug op tien jaar CNCF en vertelt hoe de community zich steeds opnieuw heeft aangepast aan de behoeften van gebruikers: van de komst van Prometheus en containerd, tot GitOps-tools als Flux en Argo, en de opmars van OpenTelemetry als dé standaard voor observability. Chris legt uit dat Kubernetes veel meer is dan een container orchestrator. Dankzij extensies en CRD’s wordt het steeds vaker gezien als de “Linux van de cloud” – een generieke infrastructuurlaag waarop je naast containers ook VM’s, databases en zelfs AI-workloads kunt draaien. We bespreken de uitdagingen rond stateful workloads, de rol van projecten als Vitess en CloudNativePG, en hoe Kubernetes volwassen wordt in het ondersteunen van complexe scenario’s. Ook komt de toekomst aan bod: serverless patronen, betere resource-optimalisatie en de steeds hechtere verwevenheid tussen cloud native en AI. Stuur ons een bericht.

    #110 Cluster API: Kubernetes-clusters bouwen met Kubernetes zelf

    In deze aflevering spreken we opnieuw met Tim Stoop, Senior Solutions Architect bij ACC ICT BV Tim legt uit hoe je Cluster API technologie het opzetten en beheren van Kubernetes-clusters sterk vereenvoudigt door alles te abstraheren en te automatiseren. Vanuit een zogeheten management cluster kun je eenvoudig workload clusters uitrollen, ongeacht of dat nu op hardware, VMware, of een cloudprovider is. We bespreken de verschillen met tools als kubeadm en Terraform, hoe auto-scaling en providers werken, en wat de grootste lessen zijn bij het toepassen van Cluster API: de onderliggende complexiteit verdwijnt niet, maar wordt wél beter beheersbaar. Tot slot blikken we vooruit: Tim ziet een belangrijke rol voor Cluster API in de opkomst van soevereine clouds, waarbij organisaties onafhankelijk blijven van één leverancier en workloads over meerdere partijen en locaties kunnen verdelen.
