一：部署Dashboard

1.kube-proxy 开启 ipvs

[root@k8s-master ~]# kubectl get configmap kube-proxy -n kube-system -o yaml > kube-proxy-configmap.yaml
[root@k8s-master ~]# sed -i 's/mode: ""/mode: "ipvs"/' kube-proxy-configmap.yaml
[root@k8s-master ~]# kubectl apply -f kube-proxy-configmap.yaml
[root@k8s-master ~]# rm -f kube-proxy-configmap.yaml
[root@k8s-master ~]# kubectl get pod -n kube-system | grep kube-proxy | awk '{system("kubectl delete pod "$1" -n kube-system")}' 

2.下载Dashboard安装脚本

[root@master ~]# wget http://www.xingdiancloud.cn:92/index.php/s/yer7cWtxesEit2R/download/recommended.yaml

3.创建证书

[root@k8s-master ~]# mkdir dashboard-certs
[root@k8s-master ~]# cd dashboard-certs/
#创建命名空间
[root@k8s-master ~]# kubectl create namespace kubernetes-dashboard
# 创建私钥key文件
[root@k8s-master ~]# openssl genrsa -out dashboard.key 2048
#证书请求
[root@k8s-master ~]# openssl req -days 36000 -new -out dashboard.csr -key dashboard.key -subj '/CN=dashboard-cert'
#自签证书
[root@k8s-master ~]# openssl x509 -req -in dashboard.csr -signkey dashboard.key -out dashboard.crt
#创建kubernetes-dashboard-certs对象
[root@k8s-master ~]# kubectl create secret generic kubernetes-dashboard-certs --from-file=dashboard.key --from-file=dashboard.crt -n kubernetes-dashboard

4.创建管理员

创建账户
[root@k8s-master ~]# vim dashboard-admin.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
  labels:
    k8s-app: kubernetes-dashboard
  name: dashboard-admin
  namespace: kubernetes-dashboard
#保存退出后执行
[root@k8s-master ~]# kubectl create -f dashboard-admin.yaml
为用户分配权限
[root@k8s-master ~]# vim dashboard-admin-bind-cluster-role.yaml
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: dashboard-admin-bind-cluster-role
  labels:
    k8s-app: kubernetes-dashboard
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: dashboard-admin
  namespace: kubernetes-dashboard
#保存退出后执行
[root@k8s-master ~]# kubectl create -f dashboard-admin-bind-cluster-role.yaml

5.安装 Dashboard

#安装
[root@k8s-master ~]# kubectl create -f  ~/recommended.yaml

#检查结果
[root@k8s-master ~]# kubectl get pods -A  -o wide

[root@k8s-master ~]# kubectl get service -n kubernetes-dashboard  -o wide
NAME                        TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)         AGE   SELECTOR
dashboard-metrics-scraper   ClusterIP   10.1.186.219   <none>        8000/TCP        19m   k8s-app=dashboard-metrics-scraper
kubernetes-dashboard        NodePort    10.1.60.1      <none>        443:30008/TCP   19m   k8s-app=kubernetes-dashboard

6.查看并复制token

[root@master ~]# kubectl -n kubernetes-dashboard describe secret $(kubectl -n kubernetes-dashboard get secret | grep dashboard-admin | awk '{print $1}')
Name:         dashboard-admin-token-xlhzr
Namespace:    kubernetes-dashboard
Labels:       <none>
Annotations:  kubernetes.io/service-account.name: dashboard-admin
              kubernetes.io/service-account.uid: a38e8ce3-848e-4d94-abcf-4d824deeb697

Type:  kubernetes.io/service-account-token
