本文详细介绍了如何在Kubernetes环境中使用Docker下载MetricsServer镜像，创建必要的角色和权限，以及部署和配置metrics-server.yaml文件。通过kubectl应用yaml，最终在kuboard中验证安装效果。

1、下载镜像

docker pull swr.cn-east-2.myhuaweicloud.com/kuboard-dependency/metrics-server:v0.6.2

2、在任一一个主节点上创建角色，执行下面语句

kubectl create clusterrolebinding kube-proxy-cluster-admin --clusterrole=cluster-admin --user=system:kube-proxy

3、准备安装的yaml文件，metrics-server.yaml文件内容如下：

apiVersion: v1
kind: ServiceAccount
metadata:
  labels:
    k8s-app: metrics-server
  name: metrics-server
  namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  labels:
    k8s-app: metrics-server
    rbac.authorization.k8s.io/aggregate-to-admin: "true"
    rbac.authorization.k8s.io/aggregate-to-edit: "true"
    rbac.authorization.k8s.io/aggregate-to-view: "true"
  name: system:aggregated-metrics-reader
rules:
- apiGroups:
  - metrics.k8s.io
  resources:
  - pods
  - nodes
  verbs:
  - get
  - list
  - watch
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  labels:
    k8s-app: metrics-server
  name: system:metrics-server
rules:
- apiGroups:
  - ""
  resources:
  - nodes/metrics
  verbs:
