kubernetes部署2.0版本UI页面，以及容器资源使用监控（2）

大家可能都知道k8s默认有个ui界面，但是呢，一般都使用的是1版本的，今天给大家部署的是2版本页面

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

接下来开始部署

部署一共分5个步骤：
1、创建RBAC
2、创建configmap和secret
3、创建dashboard
4、创建metrics-scraper
5、创建访问的serviceaccount

我吧文件直接都配好了放到了百度网盘，你们可以直接下载解压使用

完成之后就可以通过web页面访问了

这里使用的是kubeadmin部署的，如果是二进制，需要修改api-server的参数不然无法支持metrics-server服务的

1、创建 Dashboard RBAC 部署文件
cat > k8s-dashboard-rbac.yaml <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:
k8s-app: kubernetes-dashboard

  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"]

  apiVersion: rbac.authorization.k8s.io/v1
  kind: ClusterRoleBinding
  metadata:
  name: kubernetes-dashboard
  namespace: kube-system
  roleRef:
  apiGroup: rbac.authorization.k8s.io

data:
csrf: ""

apiVersion: v1
kind: Secret
metadata:
labels:
k8s-app: kubernetes-dashboard
name: kubernetes-dashboard-key-holder

      args:
    • --auto-generate-certificates
    • --namespace=kube-system #设置为当前namespace
      volumeMounts:
    • name: kubernetes-dashboard-certs
      mountPath: /certs
    • mountPath: /tmp
      name: tmp-volume

EOF
部署 Dashboard Metrics
kubectl apply -f k8s-dashboard-metrics.yaml

kubectl apply -f k8s-dashboard-token.yaml
获取 Token

完成之后登陆页面然后看看

看到了数据

好了2版本的web-ui就完成了
有什么问题可以私信我哈
