如何配置PrometheusRules

Prometheus提供了PrometheusRules的用于创建用户自己的record来查询指标。

apiVersion: monitoring.coreos.com/v1
kind: PrometheusRule
metadata:
  name: demo
  namespace: monitoring
  labels:
    role: operator-prometheus   # 保持一致，必须配置，prometheus配置了该ruleSelector
spec: 
  groups: 
  - name:  demo
    interval: 15s
    rules:
    - record: cpu_request
      expr:   kube_pod_container_resource_requests{resource="cpu",unit="core"}
    - record: cpu_limit
      expr:   kube_pod_container_resource_limits{resource="cpu",unit="core"}
    - record: memory_request
      expr:   kube_pod_container_resource_requests{resource="memory",unit="byte"}
    - record: memory_limit
      expr:   kube_pod_container_resource_limits{resource="memory",unit="byte"}
