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=

        #- --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=

          - --deployment=metrics-server-v0.3.4

          - --container=metrics-server

          - --poll-period=

          - --estimator=exponential

          - --minClusterSize=

          #- --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
