kubernetes部署2.0版本UI頁面，以及容器資源使用監控（2）

你們可能都知道k8s默認有個ui界面，可是呢，通常都使用的是1版本的，今天給你們部署的是2版本頁面

完整部署文件 Github 地址：https://github.com/my-dlq/blog-example/tree/master/kubernetes/kubernetes-dashboard2.0.0-deploy

接下來開始部署

部署一共分5個步驟：
一、建立RBAC
二、建立configmap和secret
三、建立dashboard
四、建立metrics-scraper
五、建立訪問的serviceaccount

我吧文件直接都配好了放到了百度網盤，大家能夠直接下載解壓使用

完成以後就能夠經過web頁面訪問了

這裏使用的是kubeadmin部署的，若是是二進制，須要修改api-server的參數否則沒法支持metrics-server服務的

一、建立 Dashboard RBAC 部署文件
cat > k8s-dashboard-rbac.yaml <<EOF
apiVersion: v1
kind: ServiceAccount
metadata:
labels:
k8s-app: kubernetes-dashboard
name: kubernetes-dashboard
namespace: kube-system

apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
labels:

rules:

• apiGroups: [""]
  resources: ["secrets"]
  resourceNames: ["kubernetes-dashboard-key-holder", "kubernetes-dashboard-certs", "kubernetes-dashboard-csrf"]
  verbs: ["get", "update", "delete"]
• apiGroups: [""]
  resources: ["configmaps"]
  resourceNames: ["kubernetes-dashboard-settings"]
  verbs: ["get", "update"]

完成以後登錄頁面而後看看

看到了數據

好了2版本的web-ui就完成了有什麼問題能夠私信我哈
