# 一、环境 #

<table> 
 <tbody> 
  <tr> 
   <td>软件</td> 
   <td>版本</td> 
  </tr> 
  <tr> 
   <td>kubernetes</td> 
   <td>1.10.5</td> 
  </tr> 
  <tr> 
   <td>dashboard</td> 
   <td>v1.8.3</td> 
  </tr> 
 </tbody> 
</table>

# 二、配置dashboard.yaml #

从[https://raw.githubusercontent.com/kubernetes/dashboard/v1.8.3/src/deploy/recommended/kubernetes-dashboard.yaml][https_raw.githubusercontent.com_kubernetes_dashboard_v1.8.3_src_deploy_recommended_kubernetes-dashboard.yaml]下载yaml配置文件。

或者从[https://github.com/sealire/k8s-config/blob/main/dashboard.yaml][https_github.com_sealire_k8s-config_blob_main_dashboard.yaml]下载我修改后的dashboard配置文件。

修改kubernetes-dashboard的镜像地址的端口，以及Service，增加了一个NodePort类型的Service。

修改api-server启动参数，增加如下配置

**--anonymous-auth=false**

如果kubernetes安装了ca证书，在生成server.csr的配置文件中增加kubernetes的clusterip，可通过kubectl get service获取该clusterip地址。如下所示：

[req]
    req_extensions = v3_req
    distinguished_name = req_distinguished_name
    [req_distinguished_name]
    [ v3_req ]
    basicConstraints = CA:FALSE
    keyUsage = nonRepudiation, digitalSignature, keyEncipherment
    subjectAltName = @alt_names
    [alt_names]
    DNS.1 = kubernetes
    DNS.2 = kubernetes.default
    DNS.3 = kubernetes.default.svc
    DNS.4 = kubernetes.default.svc.cluster.local
    DNS.5 = cloud-i						#cloud-i hostname
    IP.1 = 10.10.0.1					#cloud-i clusterip 可通过kubectl get service获取
    IP.2 = 192.168.0.11					#cloud-i ip
    IP.3 = 10.0.0.1						#cloud-i clusterip 可通过kubectl get service获取

# 三、启动dashboard #

配置好dashboard的yaml文件后，通过如下命令启动dashboard：

**kubectl create -f dashboard.yaml**

在dashboard.yaml中，配置了NodePort类型的Service，绑定了node主机的本地端口，直接访问nodeIP:nodePort即可打开dashboard监控页面。如下所示：
