1.下载软件

git clone https://github.com/kubernetes-incubator/metrics-server

2.修改deployment文件

vim metrics-server/deploy/kubernetes/metrics-server-deployment.yaml

apiVersion: v1
kind: ServiceAccount
metadata:
  name: metrics-server
  namespace: kube-system
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: metrics-server
  namespace: kube-system
  labels:
    k8s-app: metrics-server
......
containers
      - name: tmp-dir
        emptyDir: {}
      containers:
      - name: metrics-server
        image: k8s.gcr.io/metrics-server-amd64:v0.3.6
        command: #adding lines
        - /metrics-server
        - --kubelet-insecure-tls
        - --kubelet-preferred-address-types=InternalIP
        imagePullPolicy: IfNotPresent
        ......
    

3.应用配置文件

kubectl apply -f metrics-server/deploy/kubernetes/

4.查看结果

kubectl get pod -n kube-system -owide
