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
本次部署环境为k8s多Master节点
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

kubectl create secret generic kubernetes-dashboard-certs --from-file=./ -n kube-system
5. 通过kubectl creste命令创建resources
5.1 dashboard-rbac.yaml
规定kubernetes-dashboard-minimal该角色的权限：例如其中具备获取更新删除等不同的权限
[root@master01 dashboard]# kubectl create -f dashboard-rbac.yaml role.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created #有几个kind就会有几个结果被创建，格式为kind+apiServer/name
查看类型为Role,RoleBinding的资源对象kubernetes-dashboard-minimal是否生成
[root@master01 dashboard]# kubectl get role,rolebinding -n kube-system #-n kube-system表示查看指定命名空间中的pod，缺省值为default NAME AGE role.rbac.authorization.k8s.io/extension-apiserver-authentication-reader 3d8h role.rbac.authorization.k8s.io/kubernetes-dashboard-minimal 2m42s role.rbac.authorization.k8s.io/system::leader-locking-kube-controller-manager 3d8h role.rbac.authorization.k8s.io/system::leader-locking-kube-scheduler 3d8h role.rbac.authorization.k8s.io/system:controller:bootstrap-signer 3d8h role.rbac.authorization.k8s.io/system:controller:cloud-provider 3d8h role.rbac.authorization.k8s.io/system:controller:token-cleaner 3d8h NAME AGE rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard-minimal 2m42s rolebinding.rbac.authorization.k8s.io/system::leader-locking-kube-controller-manager 3d8h rolebinding.rbac.authorization.k8s.io/system::leader-locking-kube-scheduler 3d8h rolebinding.rbac.authorization.k8s.io/system:controller:bootstrap-signer 3d8h rolebinding.rbac.authorization.k8s.io/system:controller:cloud-provider 3d8h rolebinding.rbac.authorization.k8s.io/system:controller:token-cleaner 3d8h
5.2 dashboard-secret.yaml
证书和密钥创建
[root@master01 dashboard]# kubectl create -f dashboard-secret.yaml secret/kubernetes-dashboard-certs created secret/kubernetes-dashboard-key-holder created
查看类型为Secret的资源对象kubernetes-bashboard-crets,kubernetes-dashboard-key-holder是否生成
[root@master01 dashboard]# kubectl get secret -n kube-system NAME TYPE DATA AGE default-token-4nhtx kubernetes.io/service-account-token 3 3d8h kubernetes-dashboard-certs Opaque 0 107s kubernetes-dashboard-key-holder Opaque 0 107s
5.3 dashboard-configmap.yaml
配置文件，对于集群dashboard设置的创建
[root@master01 dashboard]# kubectl create -f dashboard-configmap.yaml configmap/kubernetes-dashboard-settings created
查看类型为ConfigMap的资源对象kubernetes-dashboard-settings是否生成
[root@master01 dashboard]# kubectl get configmap -n kube-system NAME DATA AGE extension-apiserver-authentication 1 3d8h kubernetes-dashboard-settings 0 73s
5.4 dashboard-controller.yaml
创建容器需要的控制器以及服务账户
[root@master01 dashboard]# kubectl create -f dashboard-controller.yaml serviceaccount/kubernetes-dashboard created deployment.apps/kubernetes-dashboard created
查看类型为ServiceAccount,Deployment的资源对象kubernetes-dashboard-setting是否生成
[root@master01 dashboard]# kubectl get serviceaccount,deployment -n kube-system NAME SECRETS AGE serviceaccount/default 1 3d8h serviceaccount/kubernetes-dashboard 1 2m39s NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE deployment.extensions/kubernetes-dashboard 1 1 1 1 2m39s
5.5 dashboard-service.yaml
将服务发布出去
[root@master01 dashboard]# kubectl create -f dashboard-service.yaml service/kubernetes-dashboard created
查看创建在指定的kube-system命名空间下的pod和service状态信息
[root@master01 dashboard]# kubectl get pods,svc -n kube-system -o wide #svc为service的缩写，可用 NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE pod/kubernetes-dashboard-65f974f565-nk4r8 1/1 Running 0 5m7s 172.17.97.3 192.168.122.12 <none> NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE SELECTOR service/kubernetes-dashboard NodePort 10.0.0.98 <none> 443:30001/TCP 3m37s k8s-app=kubernetes-dashboard
6. 为node节点准备加载dashboard镜像（node节点，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 #上传镜像包 rz waiting to receive. [root@node01 opt]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE nginx latest 87a94228f133 2 weeks ago 133MB centos 7 eeb6ee3f44bd 6 weeks ago 204MB nginx 1.14 295c7be07902 2 years ago 109MB registry.cn-hangzhou.aliyuncs.com/google-containers/pause-amd64 3.0 99e59f495ffa 5 years ago 747kB [root@node01 opt]# docker load -i dashboard.tar #载入该镜像 23ddb8cbb75a: Loading layer [==================================================>] 102.8MB/102.8MB Loaded image: siriuszg/kubernetes-dashboard-amd64:v1.8.3 [root@node01 opt]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE nginx latest 87a94228f133 2 weeks ago 133MB centos 7 eeb6ee3f44bd 6 weeks ago 204MB nginx 1.14 295c7be07902 2 years ago 109MB siriuszg/kubernetes-dashboard-amd64 v1.8.3 784cf2722f44 3 years ago 102MB registry.cn-hangzhou.aliyuncs.com/google-containers/pause-amd64 3.0 99e59f495ffa 5 years ago 747kB
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/
2021/11/01 02:35:39 [INFO] generate received request
2021/11/01 02:35:39 [INFO] received CSR

specifically, section 10.2.3 ("Information Requirements").
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 dashboard]# kubectl apply -f dashboard-controller.yaml Warning: kubectl apply should be used on resource created by either kubectl create --save-config or kubectl apply serviceaccount/kubernetes-dashboard configured Warning: kubectl apply should be used on resource created by either kubectl create --save-config or kubectl apply deployment.apps/kubernetes-dashboard configured
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 dashboard]# kubectl get pods,svc -n kube-system -o wide NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE pod/kubernetes-dashboard-7dffbccd68-d8nzh 1/1 Running 0 2m39s 172.17.54.4 node01 <none> NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE SELECTOR service/kubernetes-dashboard NodePort 10.0.0.98 <none> 443:30001/TCP 149m k8s-app=kubernetes-dashboard
查看发现node节点更换为node1，也就是192.168.122.11。
端口号仍是30001。
7.1.6 访问查看
到此页面，说明可以访问，保持该页面，测试下一个浏览器。
7.2 火狐浏览器
进入该页面，说明可以访问，保持该页面，测试下一个浏览器。
7.3 360浏览器
360浏览器虽然显示证书风险，但未出现任何阻止浏览或风险提示窗口，直接可进入登录页面。
7.4 令牌获取
7.4.1 使用k8s-admin.yaml文件进行创建令牌
[root@master01 dashboard]# kubectl create -f k8s-admin.yaml serviceaccount/dashboard-admin created clusterrolebinding.rbac.authorization.k8s.io/dashboard-admin created
7.4.2 获取token简要信息，名称为dashboard-admin-token-xxxxx
[root@master01 dashboard]# kubectl get secrets -n kube-system NAME TYPE DATA AGE dashboard-admin-token-n5dcl kubernetes.io/service-account-token 3 86s default-token-4nhtx kubernetes.io/service-account-token 3 3d11h kubernetes-dashboard-certs Opaque 11 19m kubernetes-dashboard-key-holder Opaque 2 170m kubernetes-dashboard-token-kkpxs kubernetes.io/service-account-token 3 165m
7.4.3 查看令牌序列号，截取“token:”后面的内容
[root@master01 dashboard]# kubectl describe secrets dashboard-admin-token-n5dcl -n kube-system
Name: dashboard-admin-token-n5dcl
Namespace: kube-system
Labels: <none>
