A pod is considered as QoS ensured if it meets the requirements described below. If it does, it will be executed on nodes where only such pods are running.

QoS ensured pod should have this spec.resources specifications:

• requests.memory equal to limits.memory and not equal to zero
• requests.cpu not zero

Installation

Taint nodes as k8s.smp.io/qos=enforced:NoExecute and label them as k8s.smp.io/qos=enforced.

Pods that match QoS ensured criterias will be scheduled on these nodes only.
