1. 将上述文件保存为 prometheus-additional.yaml，创建secret

kubectl create secret generic additional-configs --from-file=prometheus-additional.yaml -n monitoring

2. 修改CRD为prometheus的文件
   

3. 添加service文件的注释

  annotations:
    prometheus.io/scrape: "true"
    prometheus.io/port: "8000"
    prometheus.io/scheme: "http"
    prometheus.io/path: "/metrics"
