* Set small CPU requests on static pods kube-apiserver, kube-controller-manager, and kube-scheduler to align with upstream tooling and for edge cases * Effectively, a practical case for these requests hasn't been observed. However, a small static pod CPU request may offer a slight benefit if a controller became overloaded and the below mechanisms were insufficient Existing safeguards: * Control plane nodes are tainted to isolate them from ordinary workloads. Even dense workloads can only compress CPU resources on worker nodes. * Control plane static pods use the highest priority class, so contention favors control plane pods (over say node-exporter) and CPU is compressible too.
