Kubernetes v1.36: Tiered Memory Protection with Memory QoS
On behalf of SIG Node, we are pleased to announce updates to the Memory QoS feature (alpha) in Kubernetes v1.36. Memory QoS uses the cgroup v2 memory controller to give the kernel better guidance on how to treat container memory. It was first introduced in v1.22 and updated in v1.27. In Kubernetes v1.36, we're introducing: opt-in memory reservation, tiered protection by QoS class, observability metrics, and kernel-version warning for memory.high. What's new in v1.36Opt-in memory reservation with memoryReservationPolicyv1.36 separates throttling from reservation. Enabling the feature gate turns on memory.high throttling (the kubelet sets memory.high based on memoryThrottlingFactor, default 0.9), but memory reservation is now controlled by a separate kubelet configuration field: None (defaul
