第 7 章 使用拓扑管理器

流程

1. 启用 LatencySensitive FeatureGate

   # oc edit featuregate/cluster

   Copy to Clipboard Toggle word wrap

2. 添加 Feature Set: LatencySensitive 到 spec：

   # oc describe featuregate/cluster
   
   Name:         cluster
   Namespace:
   Labels:       <none>
   Annotations:  release.openshift.io/create-only: true
   API Version:  config.openshift.io/v1
   Kind:         FeatureGate
   Metadata:
     Creation Timestamp:  2019-10-30T15:06:41Z
     Generation:          2
     Resource Version:    7773803
     Self Link:           /apis/config.openshift.io/v1/featuregates/cluster
     UID:                 b00204ab-cc5e-4ca5-ad93-b9bdd738c1de
   Spec:
     Feature Set:  LatencySensitive
   Events:         <none>

3. 使用 KubeletConfig 配置 Topology Manager 策略。

   以下 YAML 文件示例显示了一个指定的 single-numa-node 策略。

   apiVersion: machineconfiguration.openshift.io/v1
   kind: KubeletConfig
   metadata:
     name: cpumanager-enabled
   spec:
     machineConfigPoolSelector:
       matchLabels:
         custom-kubelet: cpumanager-enabled
     kubeletConfig:
        cpuManagerPolicy: static
        cpuManagerReconcilePeriod: 5s
        topologyManagerPolicy: single-numa-node
