metrics-server出现 no metrics known for node

1.下载metrics-server
git clone -b v0.3.6 https://github.com/kubernetes-incubator/metrics-server

cd  ./metrics-server/deploy/1.8+/

2.修改metrics-server-deployment.yaml

      hostNetwork: true
      serviceAccountName: metrics-server
      volumes:
      # mount in tmp so we can safely use from-scratch images and/or read-only containers
      - name: tmp-dir
        emptyDir: {}
      containers:
      - name: metrics-server
        image: k8s.gcr.io/metrics-server-amd64:v0.3.6
        imagePullPolicy: Always
        args:
        - --kubelet-insecure-tls
        - --kubelet-preferred-address-types=InternalIP

3.安装metrics-server
[root@master 1.8+]# pwd
/root/yaml/metrics-server/deploy/1.8+
[root@master 1.8+]# kubectl apply -f ./

 

  备注：如果遇到api不支持需要替换对应yaml的接口即可，用下面命令查找现在支持的

kubectl api-versions
