## 一：部署Dashboard
|
|||
|
|
|
|||
|
|
#### 1.kube-proxy 开启 ipvs
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
[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
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
[root@master ~]# wget http://www.xingdiancloud.cn:92/index.php/s/yer7cWtxesEit2R/download/recommended.yaml
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
#### 3.创建证书
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
[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
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
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
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
#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
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
[root@master ~]# kubectl -n kubernetes-dashboard describe secret $(kubectl -n kubernetes-dashboard get secret | grep dashboard-admin | awk '{print $1}')
|
|||
|
|
