1. Dashboard 介绍

Dashboard（仪表盘）是基于 Web 的 Kubernetes 用户界面。
可以使用仪表盘将容器化应用程序部署到 Kubernetes 集群，对容器化应用程序进行故障排除，并管理集群本身机器伴随资源。
可以使用仪表盘来概述集群上运行的应用程序，以及创建或修改单个 Kubernetes 资源（例如部署，作业，守护进程等）。
例如：可以使用部署向导扩展部署，启动滚动更新，重新启动 Pod 或部署新应用程序。仪表盘还提供有关集群中 Kubernetes 资源状态以及可能发生的任何错误的信息。

2. 服务器环境

3. 在 K8S 工具目录中创建 dashboard 工作目录

[root@master01 ~]# mkdir /opt/k8s/dashboard
[root@master01 ~]# cd !$
cd /opt/k8s/dashboard
[root@master01 dashboard]# rz -E
#上传 Dashboard.zip 压缩包
rz waiting to receive.
[root@master01 dashboard]# unzip Dashboard.zip 
#解压
Archive:  Dashboard.zip
  inflating: dashboard-configmap.yaml  
  inflating: dashboard-controller.yaml  
  inflating: dashboard-rbac.yaml     
  inflating: dashboard-secret.yaml   
  inflating: dashboard-service.yaml  
  inflating: k8s-admin.yaml          
  inflating: dashboard-cert.sh       
[root@master01 dashboard]# ls
dashboard-cert.sh         dashboard-controller.yaml  dashboard-secret.yaml   Dashboard.zip
dashboard-configmap.yaml  dashboard-rbac.yaml        dashboard-service.yaml  k8s-admin.yaml

4. 核心文件说明核心文件说明dashboard-rbac.yaml用于访问控制设置，配置各种角色的访问控制权限及角色绑定（绑定角色和服务账户），内容中包含对应各种角色所配置的规则（rules）dashboard-secret.yaml提供令牌，访问API服务器所用（个人理解为一种安全认证机制）dashboard-configmap.yaml配置模板文件，负责设置Dashboard的文件，ConfigMap提供了将配置数据注入容器的方式，保证容器中的应用程序配置从Image内容中解耦dashboard-controller.yaml负责控制器即服务账户的创建，来管理pod副本dashboard-service.yaml负责将容器中的服务提供出去，供外部访问Dashboard一共有7个文件，其中包含5个构建该界面的核心文件，一个k8s-admin.yaml文件是自己写的，用来生成待会在浏览器中登录时所用的令牌；一个dashboard-cert.sh，用来快速生成解决谷歌浏览器加密通信所需的证书文件。核心文件官方下载资源地址：https://github.com/kubernetes/kubernetes/tree/master/cluster/addons/dashboard 4.1 查看 dashboard-rbac.yaml

6. 为 node 节点准备加载 dashboard 镜像（以 node01 为例，该步骤可省略） 
为提高速度，我这里已将 siriuszg/kubernetes-dashboard-amd64:v1.8.3 镜像压缩成 tar 包，在 node 节点释放该镜像。该步骤也可省略，node节点会通过kubernetes公有仓库去自动拉取该镜像。 
[root@node01 ~]# cd /opt
[root@node01 opt]# rz -E

7. 访问测试（多浏览器） 
不同浏览器的安全访问策略和防护级别是不同的，由于我们没有给 dashboard 做证书，因此使用不同的浏览器可能会出现不同的效果，本次使用我们最常用的 Edge/Chrome、火狐以及 360 浏览器进行测试。
 由于 dashboard-service.yaml 定义的 nodePort:30001，因此我们的测试地址应该是 pod 所属 node 的 30001 端口。 
7.1 Edge浏览器 
 
无法访问，由于Edge使用的是Chrome内核，因此Google的Chrome也是相同效果，可通过以下步骤查看问题。
 
 
 chrome浏览器在Security项下查看
 
 发现问题是缺少证书，那么我们为其制作证书即可。 
7.1.1 修改 dashbaord-controller.yaml 
[root@master01 dashboard]# cd /opt/k8s/dashboard/
[root@master01 dashboard]# vim dashboard-controller.yaml 
 
......
        args:
          # PLATFORM-SPECIFIC ARGS HERE
##在文件的第47行下面添加以下两行，指定加密（tls）的私钥和证书文件
          - --auto-generate-certificates
          - --tls-key-file=dashboard-key.pem
          - --tls-cert-file=dashboard.pem
 
7.1.2 执行脚本 dashboard-cret.sh 
[root@master01 dashboard]# cd /opt/k8s/dashboard/
[root@master01 dashboard]# chmod +x dashboard-cert.sh 
[root@master01 dashboard]# ./dashboard-cert.sh /opt/k8s/k8s-cert/

secret "kubernetes-dashboard-certs" deleted
secret/kubernetes-dashboard-certs created
 
7.1.3 在 dashboard 工作目录下将生成两个证书、 
[root@master01 dashboard]# ls *.pem
dashboard-key.pem  dashboard.pem
 
7.1.4 重新部署 dashboard-controller.yaml 
注意：当 apply 不生效时，先使用 delete 清除资源，再 apply 创建资源 
[root@master01 /opt/k8s/dashboard]# kubectl delete -f dashboard-controller.yaml
serviceaccount "kubernetes-dashboard" deleted
deployment.apps "kubernetes-dashboard" deleted

[root@master01 /opt/k8s/dashboard]# kubectl apply -f dashboard-controller.yaml

7.1.5 查看分配节点和端口号 
由于可能会更换所分配的节点，所以要再次查看一下分配的节点服务器地址和端口号 
[root@master01 ~]# kubectl get pods,svc -n kube-system -o wide
NAME                                        READY   STATUS    RESTARTS   AGE   IP           NODE             NOMINATED NODE
