在K8S中，已经部署了 Istio 服务网格，且开启了 meshConfig.enablePrometheusMerge=true（默认是开启的），详情请看这里 Istio 开启 Prometheus 指标合并，修改完配置后，需要重启 Pod。

  • Deployment 部署文件，告知 Istio 从 :9101/metrics 地址获取指标
apiVersion: apps/v1
kind: Deployment
spec:
  template:
    metadata:
      annotations:
        # 补充这三条注解
        prometheus.io/path: '/metrics'
        prometheus.io/port: '9101'
        prometheus.io/scrape: 'true'
  • Configmap 配置文件，开启 Prometheus 监控端口
apiVersion: v1
kind: ConfigMap
data:
  user.yaml: |
    # prometheus监控
    Prometheus:
      Host: 0.0.0.0
      Port: 9101
      Path: /metrics

如果要变更端口，则需要同时修改以上两个地方，且要保持一致
