victoriamonitor监控gcp的cloudrun

方案总览

VictoriaMetrics 无法直接 scrape Cloud Run 的 /metrics，因为：
Cloud Run 是动态实例，没有固定 IP；
Cloud Run 实例按需启动/销毁；
没有暴露容器内部端口供 scraping。
所以正确的做法是：
[Cloud Run 服务指标]
↓
[Cloud Monitoring (Stackdriver)]
↓
[Prometheus /metrics 接口 (Google Managed Prometheus Adapter)]
↓
[vmagent 或 VictoriaMetrics 集群采集]

一、前提条件

用以下命令生成了 GCP 服务账号的密钥：

gcloud iam service-accounts keys create vmagent-key.json \
  --iam-account vmagent-monitor@YOUR_PROJECT_ID.iam.gserviceaccount.com

二、把密钥转为 Base64

Kubernetes Secret 里的数据必须是 Base64 编码的。
运行下面命令：

cat vmagent-key.json | base64 -w 0


（macOS 用：base64 -b 0）

输出会是一长串 Base64 字符串，例如：

ewogICJ0eXBlIjogInNlcnZpY2VfYWNjb3VudCIsCiAg...

🧾 三、创建 YAML 文件

把输出填到下面这个模板里 👇

apiVersion: v1
kind: Secret
metadata:
  name: gcp-token
  namespace: monitoring   # 或你自己的命名空间
type: Opaque
data:
  credentials.json: ewogICJ0eXBlIjogInNlcnZpY2VfYWNjb3VudCIsCiAg...   # <== 这里替换为你的 base64 编码内容


保存为：

gcp-secret.yaml

🚀 四、应用到集群

kubectl apply -f gcp-secret.yaml

验证：

kubectl get secret gcp-token -n monitoring -o yaml

你会看到编码后的内容在 data.credentials.json 里。

🧩 五、在 Deployment / Pod 中使用

举例：vmagent Deployment 里挂载这个 Secret👇

apiVersion: apps/v1
kind: Deployment
metadata:
  name: gcp-cloudrun-detailed-exporter
  namespace: vm
spec:
  replicas: 1
  selector:
    matchLabels:
      app: gcp-cloudrun-detailed-exporter
  template:
    metadata:
      labels:
        app: gcp-cloudrun-detailed-exporter
    spec:
      containers:
      - name: stackdriver-exporter
        image: prometheuscommunity/stackdriver-exporter:latest
        ports:
        - containerPort: 9255
          name: metrics
        args:
          - --monitoring.metrics-prefixes=run.googleapis.com
        env:
        - name: GOOGLE_APPLICATION_CREDENTIALS
          value: /etc/gcp/credentials.json
        - name: GOOGLE_PROJECT_ID
          value: "aiart-develop"
        volumeMounts:
        - name: gcp-credentials
          mountPath: /etc/gcp
          readOnly: true
        resources:
          requests:
            memory: "256Mi"
            cpu: "200m"
          limits:
            memory: "512Mi"
            cpu: "500m"
      volumes:
      - name: gcp-credentials
        secret:
          secretName: seaart-cloudrun-token

这样，容器中就能自动读取 /var/secrets/google/credentials.json，使用该 GCP 账号身份访问监控接口。

六、创建service

暴露metric端口

apiVersion: v1
kind: Service
metadata:
  name: gcp-cloudrun-detailed-exporter
  namespace: vm
  labels:
    app: gcp-cloudrun-detailed-exporter
spec:
  selector:
    app: gcp-cloudrun-detailed-exporter
  ports:
  - port: 9255
    targetPort: 9255
    name: metrics

七、部署刮擦配置

自动抓取cloudrun的指标

apiVersion: operator.victoriametrics.com/v1beta1
kind: VMServiceScrape
metadata:
  name: gcp-cloudrun-detailed-exporter
  namespace: vm
spec:
  jobName: gcp-cloudrun-detailed-exporter
  endpoints:
    - port: metrics
      interval: 1m
      path: /metrics
  selector:
    matchLabels:
      app: gcp-cloudrun-detailed-exporter

接下来是配置grafana的dashboard

直接导入json模版
