The Next Generation of DaemonSet Autoscaling

summary
Prototype implements per-pod VPA for DaemonSets by adding a scope field so each pod on each node gets its own recommendation rather than one value for all. Demo runs on a three‑node kind cluster with a logging daemon, tuned VPA to react faster, evicts the hot pod and raises its CPU request only on that node, reducing wasted reservation on others. Proposal and demo code appear as scope=hostName and are linked in PR 7942 and PR 7978.
