4.2. 通用配置选项

您可针对 Pod 和卷调整 CPU、内存或存储资源请求和/或限值。以下 default-resource-limits.yaml 提供了一个针对各个组件设置资源请求和限值的示例。

apiVersion: metering.openshift.io/v1
kind: MeteringConfig
metadata:
  name: "operator-metering"
spec:
  reporting-operator:
    spec:
      resources:
        limits:
          cpu: 1
          memory: 500Mi
        requests:
          cpu: 500m
          memory: 100Mi
  presto:
    spec:
      coordinator:
        resources:
          limits:
            cpu: 4
            memory: 4Gi
          requests:
            cpu: 2
            memory: 2Gi

      worker:
        replicas: 0
        resources:
          limits:
            cpu: 8
            memory: 8Gi
          requests:
            cpu: 4
            memory: 2Gi

  hive:
    spec:
      metastore:
        resources:
          limits:
            cpu: 4
            memory: 2Gi
          requests:
            cpu: 500m
            memory: 650Mi
        storage:
          class: null
          create: true
          size: 5Gi
      server:
        resources:
          limits:
            cpu: 1
            memory: 1Gi
          requests:
            cpu: 500m
            memory: 500Mi

您可以在特定节点集合上运行 metering 组件。在 metering 组件上设置 nodeSelector 来控制组件的调度位置。以下 node-selectors.yaml 文件提供了一个针对各个组件设置节点选择器的示例。

apiVersion: metering.openshift.io/v1
kind: MeteringConfig
metadata:
  name: "operator-metering"
spec:
  reporting-operator:
    spec:
      nodeSelector:
        "node-role.kubernetes.io/infra": "" 1

  presto:
    spec:
      coordinator:
        nodeSelector:
          "node-role.kubernetes.io/infra": "" 2
      worker:
        nodeSelector:
          "node-role.kubernetes.io/infra": "" 3
  hive:
    spec:
      metastore:
        nodeSelector:
          "node-role.kubernetes.io/infra": "" 4
      server:
        nodeSelector:
          "node-role.kubernetes.io/infra": "" 5
