1) 修改metrics-server-deployment.yaml

[root@hadoop01 metrics-server]# vim metrics-server-deployment.yaml
      containers:
      - name: metrics-server
        image: registry.aliyuncs.com/google_containers/metrics-server-amd64:v0.3.4
        command:
        - /metrics-server
        - --metric-resolution=30s
        #- --kubelet-port=10255
        #- --deprecated-kubelet-completely-insecure=true
        - --kubelet-insecure-tls
        - --kubelet-preferred-address-types=InternalIP,Hostname,InternalDNS,ExternalDNS,ExternalIP
.......
.......
.......
.......
        command:
          - /pod_nanny
          - --config-dir=/etc/config
          #- --cpu={{ base_metrics_server_cpu }}
          - --extra-cpu=0.5m
          #- --memory={{ base_metrics_server_memory }}
          #- --extra-memory={{ metrics_server_memory_per_node }}Mi
          - --threshold=5
          - --deployment=metrics-server-v0.3.4
          - --container=metrics-server
          - --poll-period=300000
          - --estimator=exponential
          - --minClusterSize=2
          #- --minClusterSize={{ metrics_server_min_cluster_size }}

2)修改resource-reader.yaml

rules:
- apiGroups:
  - ""
  resources:
  - pods
  - nodes
  - nodes/stats //加上这个
  - namespaces
  verbs:
  - get
  - list
  - watch

3)重新apply

kubectl apply -f metrics-server-deployment.yaml
