Ever wondered why `kubectl get all` doesn't actually get all your resources? It conveniently ignores Ingresses, PersistentVolumeClaims, and many other resource types. Even worse, when you do list everything in a namespace, you're left staring at a pile of disconnected objects with no way to understand how they relate to each other or form complete systems. This video dives into this fundamental Kubernetes problem and explores how ownerReferences and resource hierarchies actually work under the hood.
To solve this challenge, I built a custom Solution CRD that wraps related resources into logical groups with clear context, intent, and aggregated status. Instead of manually piecing together which Deployments, Services, Ingresses, and databases belong to the same application, you can now define and query complete solutions as first-class citizens in your cluster. I'll walk you through the problem, demonstrate tools like kubectl-tree for exploring ownership hierarchies, and show you how this simple CRD approach finally answers questions like "What is this app?" and "Is my entire system healthy?" Check out the project at github.com/vfarcic/dot-ai-controller if you want to try it yourself.
