What Kubernetes becomes over the next 10 years will depend on how it adapts to AI workloads and agentic applications. Mauricio Salatino expects those changes to reshape the platform and raise the bar for developer tooling. He believes the future of Kubernetes will be defined by how easily teams can build and deploy these new (AI) workloads. Watch the full interview: https://ku.bz/QXKc1tBFY

This article explains what really happens when you run kubectl apply, and how server-side apply moves field ownership into the API server so Helm, Argo CD and HPAs hit conflicts. More: https://ku.bz/KZ_RzWBV5

k is a small kubectl wrapper that lets you switch context, cluster, and namespace inline with short prefixes instead of typing out long flags every time. More: https://ku.bz/nGDPGD1Zr

Kube Select is here. It tests one claim: more telemetry does not yield better decisions. Henrik Rexed of Dynatrace joins hosts Salman Iqbal and Bart Farrell to test it. You will learn: - how service ownership gives telemetry incident context - why proxy metrics can produce extreme data volume - how AI agents run queries before human review Watch: https://ku.bz/848pmBN5_ 🌟 Kubernetes moves too fast to track everything.

AI optimizing AI — that's what Andrew Hillier and the team at Kubex shipped at KubeCon. The trend is clear: agentic management is coming to Kubernetes. Instead of static rules, AI analyzes your environment and optimizes GPU utilization dynamically. Combined with advances in DRA (Dynamic Resource Allocation) and Kubernetes 1.35 improvements, the ecosystem is finally getting the tools to solve GPU underutilization at scale. These GPUs are expensive. Seeing them sit idle is painful. The tooling is catching up. Watch the full interview: https://ku.bz/wL-0d1X0y

Running Java on Kubernetes? CPU and memory limits affect much more than scheduling. A 4 GiB heap requires a container larger than 4 GiB. Fractional CPU limits can also change the processor count that HotSpot sees. In our new article, you will learn: - Why JVM heap size and container memory are different boundaries - How CPU limits affect garbage collection, worker pools, and application performance - Which JVM and container metrics to collect when validating resource settings under load The article also includes practical experiments and an interactive configuration calculator.

Kubernetes turned 10 last year. What does the next decade look like? Abby Bangser sees Kubernetes becoming like Linux — essential infrastructure that fades into the background. The core will solidify while the community shifts focus to higher-level abstractions. AI workloads are accelerating this: they're being built on Kubernetes, which pushes it further into the "operating system" layer that teams build on top of rather than interact with directly. The future of Kubernetes isn't more Kubernetes — it's what gets built on top of it. Watch the full interview: https://ku.bz/5Rqq275dl

Introducing Kube Signals: the new KubeFM show that turns keynote trends into direct conversations with the speakers shaping them. For episode one, Brian Teller sits down with Saiyam Pathak from vCluster after his KubeCon India keynote on AI factories. They examine why the GPU beneath the model is becoming a platform-engineering problem. They discuss: - Why whole-GPU allocation wastes capacity - How DRA, HAMI, MIG, and MPS enable sharing - What Kubernetes must learn to support AI factories Watch the full episode: https://ku.bz/4QZDqrnf- This episode is sponsored by LearnKube.
