概述

Kubernetes基础环境的安装部署请参照:https://lolicp.com/kubernetes/20211532.html

开始准备部署

根据 Kubernetes 版本选择 Kubernetes 仪表板的版本号，具体如下表：

可以前往https://github.com/kubernetes/dashboard/releases/tag/查看Kubernetes 仪表板对应版本表

下载配置文件

由于特殊原因，国内无法直接访问外网。请提前下载好文件后拷贝。

[root@master-all ~]# wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-beta4/aio/deploy/recommended.yaml

开始导入配置

[root@master-all ~]#  kubectl apply -f recommended.yaml
namespace/kubernetes-dashboard created
serviceaccount/kubernetes-dashboard created
service/kubernetes-dashboard created
secret/kubernetes-dashboard-certs created
secret/kubernetes-dashboard-csrf created
secret/kubernetes-dashboard-key-holder created
configmap/kubernetes-dashboard-settings created
role.rbac.authorization.k8s.io/kubernetes-dashboard created
clusterrole.rbac.authorization.k8s.io/kubernetes-dashboard created
rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created
clusterrolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created
deployment.apps/kubernetes-dashboard created
service/dashboard-metrics-scraper created
deployment.apps/dashboard-metrics-scraper created

查看pod状态

[root@master-all ~]# kubectl get pod -n kubernetes-dashboard -o wide
NAME                                         READY   STATUS    RESTARTS   AGE    IP               NODE     NOMINATED NODE   READINESS GATES
dashboard-metrics-scraper-66b49655d4-g8g4z   1/1     Running   0          2m8s   10.103.119.130   node-1   <none>           <none>
kubernetes-dashboard-74b4487bfc-vsr2z        1/1     Running   0          2m8s   10.103.119.129   node-1   <none>           <none>

查看服务状态

[root@master-all ~]# kubectl get service -n kubernetes-dashboard
NAME                        TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)    AGE
dashboard-metrics-scraper   ClusterIP   10.102.112.220   <none>        8000/TCP   9m31s
kubernetes-dashboard        ClusterIP   10.111.1.77      <none>        443/TCP    9m32s

配置用户

创建用户配置

创建一个admin-user用户，编辑dashboard-adminuser.yaml文件，内容如下:

apiVersion: v1
kind: ServiceAccount
metadata:
  name: admin-user
  namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: admin-user
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
  - kind: ServiceAccount
    name: admin-user
    namespace: kube-system

导入仪表盘配置

[root@master-all ~]# kubectl apply -f dashboard-adminuser.yaml
serviceaccount/admin-user created
clusterrolebinding.rbac.authorization.k8s.io/admin-user created

生成证书

生成根证书及用户证书

[root@master-all ~]# awk '/client-certificate-data/ {print $2}' ~/.kube/config |head -n 1 |base64 -d >> kubecfg.crt
[root@master-all ~]# awk '/client-key-data/ {print $2}' ~/.kube/config|head -n 1 | base64 -d >> kubecfg.key

生成个人证书

如不设置密码则回车即可。

[root@master-all ~]# openssl pkcs12 -export -clcerts -inkey kubecfg.key -in kubecfg.crt -out kubecfg.p12 -name "kubernetes-client"
Enter Export Password:
Verifying - Enter Export Password:

拷贝刚刚生成的证书至你的客户端。

浏览器证书信任配置

Google浏览器证书信任配置

浏览器地址栏访问:chrome://settings/security

导入生成的个人证书

设置密码

如生成时未设置密码则无需设置，其他无特殊要求则默认下一步即可。

登陆仪表盘

仪表盘地址为:https://部署IP:6443/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/#/login

选择刚刚导入的证书

获取登录Token

[root@master-all ~]# kubectl -n kubernetes-dashboard describe secret $(kubectl -n kubernetes-dashboard get secret | awk '/kubernetes-dashboard/ {print $1}')
