Understanding Kube-Scheduler-Simulator
summary
A web-based kube-scheduler-simulator reproduces a Kubernetes control plane locally via Docker Compose, launching three containers (kube-apiserver, simulator backend and frontend) and serving the UI on port 3000 to create/edit/delete Pods, Nodes, PersistentVolumes and StorageClasses. It runs the real scheduler plus a simulator server, exposes API endpoints, and supports custom scoring plugins that produced example scores (96, 100, 200) in the demo. CI migrated from GitHub Actions to Prow and end-to-end tests are in progress; the demo shows scheduling decisions applied and the tool working end-to-end.
