配置一个Redis的exporter，我们通过redis进行暴露监控

我们在之前的Redis上添加prometheus.io/scrape=true

cat redis.yaml

apiVersion: apps/v1
    kind: Deployment
    metadata:
      name: redis
      namespace: kube-system
    spec:
      replicas: 1
      selector:
        matchLabels:
          app: redis
      template:
        metadata:
          labels:
            app: redis
        spec:
          containers:
          - name: redis
            image: redis:4
            resources:
              requests:
                cpu: 100m
                memory: 100Mi
            ports:
            - containerPort: 6379
          - name: redis-exporter
            image: oliver006/redis_exporter:latest
            resources:
              requests:
                cpu: 100m
                memory: 100Mi
            ports:
            - containerPort: 9121
    ---
    kind: Service
    apiVersion: v1
    metadata:
      name: redis
      namespace: kube-system
      annotations:
        prometheus.io/scrape: "true"
        prometheus.io/port: "9121"
    spec:
      selector:
        app: redis
      ports:
      - name: redis
        port: 6379
        targetPort: 6379
      - name: prom
        port: 9121
        targetPort: 9121

通过kubectl apply更新yaml文件

kubectl  apply -f redis.yaml

redis 这个 Pod 中包含了两个容器，一个就是 redis 本身的主应用，另外一个容器就是 redis\_exporter，由于Redis服务的metrics接口在redis-exporter 9121上，所以我们添加了prometheus.io/port=9121这样的annotation,在prometheus就会自动发现redis了，接下来我们刷新一下Redis的Service配置：

kubectl apply -f  redis.yaml

在grafana导入redis的json文件Redis Cluster-1571393212519.json，

json文件所在链接如下：
