我有一个redis集群和redis导出器，在kubernetes集群的同一个命名空间中的两个独立部署中。我正在使用prometheus操作符来监视集群，但是我找不到设置导出器和操作符的方法。我已经建立了一个针对redis导出器的服务（见下文）和一个servicemonitor（见下文）。如果我将端口转发到redis exporter服务，我可以看到度量。此外，redis exporter日志不显示问题。

apiVersion: apps/v1
kind: Deployment
metadata:
  namespace: foo
  name: redis-exporter
  labels:
    app: redis-exporter
spec:
  replicas: 1

    matchLabels:

  template:

        prometheus.io/scrape: "true"
        prometheus.io/port: "9121"

        app: redis-exporter
    spec:

        env:
        - name: REDIS_ADDR
          value:  redis-cluster.foo.svc:6379
        ports:
        - containerPort: 9121

我的服务和服务监视器

kind: Service

如果我切换到redis集群旁边的sidecar redis exporter，那么一切都正常工作。有人面临过这样的问题吗？
