Summary
Kubernetes v1.37 promotes Memory QoS to Beta, enabling it by default on Linux nodes using cgroup v2. The feature, first Alpha in v1.22, gives the kernel better guidance on container memory handling.
Key facts
- Memory QoS reached Beta in Kubernetes v1.37 and is enabled by default.
- It applies to Linux nodes running cgroup v2 via the memory controller.
- The feature was first introduced as Alpha in v1.22.
- It was expanded in v1.36.
Why it matters
Operators on Linux cgroup v2 nodes get the feature without opting in, so existing memory tuning and limits may behave differently after upgrading to v1.37.
