Secrets Not Included

The Secrets Not Included podcast shows why many IT systems in practice are insecure, unstable, or unnecessarily complex — and how to do it better.

Ole and Daniel talk about real architectures, concrete security problems, and the decisions behind them. It's not about theoretical best practices, but about solutions that stand up under real conditions: secure deployments, clean secret strategies, robust infrastructure, and well thought-out automation.

It becomes clear that security isn't an add-on — it's the result of clear technical decisions and clean processes.

Anyone responsible for systems quickly recognises where typical weak points sit — and how modern, secure platforms have to be built to run reliably in the long term.

K3s: Kubernetes ohne Overkill

Hosts

Daniel und Ole sprechen bei Affenhitze aus geheimer Outdoor-Location über K3s als pragmatischen Mittelweg zwischen Docker Compose und großem Kubernetes-Cluster: klein starten, sauber skalieren, GitOps nutzen und trotzdem nicht im Infrastruktur-Overhead versinken. Dazu geht es um Cloud-Kosten, europäische Alternativen, DevOps-Realität und die Frage, wo KI im Betrieb hilft – und wo Erfahrung weiterhin unschlagbar bleibt.
