1、k8s的dashboard的安装部署，首先需要将压缩包下载下来，然后进行解压缩操作。
1 [root@k8s-master ~]# cd k8s/ 2 [root@k8s-master k8s]# ls 3 book-master.war deploy health pod rc skydns skydns.zip svc tomcat_demo tomcat_demo.zip 4 [root@k8s-master k8s]# wget https://www.qstack.com.cn/dashboard.zip 5 --2020-06-18 20:02:26-- https://www.qstack.com.cn/dashboard.zip 6 Resolving www.qstack.com.cn (www.qstack.com.cn)... 123.125.46.149, 111.202.85.37 7 Connecting to www.qstack.com.cn (www.qstack.com.cn)|123.125.46.149|:443... connected. 8 HTTP request sent, awaiting response... 200 OK 9 Length: 1099 (1.1K) [application/zip] 10 Saving to: ‘dashboard.zip’ 11 12 100%[=======================================================================================================================================================================>] 1,099 --.-K/s in 0.05s 13 14 2020-06-18 20:02:26 (20.2 KB/s) - ‘dashboard.zip’ saved [1099/1099] 15 16 [root@k8s-master k8s]# unzip dashboard.zip 17 Archive: dashboard.zip 18 creating: dashboard/ 19 inflating: dashboard/dashboard-deploy.yaml 20 inflating: dashboard/dashboard-svc.yaml 21 [root@k8s-master k8s]#
查看配置文件dashboard-deploy.yaml，并对配置进行修改。
1 [root@k8s-master dashboard]# vim dashboard-deploy.yaml
首先，需要将kubernetes-dashboard-amd64下载下来，然后上传到私有仓库里面，方便使用。

dashboard-deploy.yaml，对配置进行修改，具体内容，如下所示。
1 apiVersion: extensions/v1beta1 2 kind: Deployment 3 metadata: 4 # Keep the name in sync with image version and 5 # gce/coreos/kube-manifests/addons/dashboard counterparts 6 name: kubernetes-dashboard-latest 7 namespace: kube-system 8 spec: 9 replicas: 1 10 template: 11 metadata: 12 labels: 13 k8s-app: kubernetes-dashboard 14 version: latest 15 kubernetes.io/cluster-service: "true" 16 spec: 17 containers: 18 - name: kubernetes-dashboard 19 image: 192.168.110.133:5000/kubernetes-dashboard-amd64:v1.10.0 20 resources: 21 # keep request = limit to keep this container in guaranteed class 22 limits: 23 cpu: 100m 24 memory: 50Mi 25 requests: 26 cpu: 100m 27 memory: 50Mi 28 ports: 29 - containerPort: 9090 30 args: 31 - --apiserver-host=http://192.168.110.133:8080 32 livenessProbe: 33 httpGet: 34 path: / 35 port: 9090 36 initialDelaySeconds: 30 37 timeoutSeconds: 30
修改的地方，如下所示：
配置完毕，创建deployment，如下所示：
1 [root@k8s-master dashboard]# kubectl create -f dashboard-deploy.yaml 2 deployment "kubernetes-dashboard-latest" created
修改dashboard-svc.yaml配置文件，其中port是VIP的端口，targetPort是容器的端口，访问vip的端口80就会跳转到targetPort的9090端口。
[root@k8s-master dashboard]# vim dashboard-svc.yaml
1 apiVersion: v1 2 kind: Service 3 metadata: 4 name: kubernetes-dashboard 5 namespace: kube-system 6 labels: 7 k8s-app: kubernetes-dashboard 8 kubernetes.io/cluster-service: "true" 9 spec: 10 selector: 11 k8s-app: kubernetes-dashboard 12 ports: 13 - port: 80 14 targetPort: 9090
开始创建svc，命令如下所示：
1 [root@k8s-master dashboard]# kubectl create -f dashboard-svc.yaml 2 service "kubernetes-dashboard" created 3 [root@k8s-master dashboard]#
创建完毕，查看是否已经正常启动了。

此时，就可以进行访问了，服务已经Running了。
2、首先，可以访问一下api-server，可以使用8080端口号。访问地址http://192.168.110.133:8080/。
接下来访问倒数第二行的/ui/，访问的效果，如下所示：
报错，如下所示：
1 the server could not find the requested resource
这里查看k8s的版本，使用kubectl version。
1 [root@k8s-master ~]# kubectl version 2 Client Version: version.Info{Major:"1", Minor:"5", GitVersion:"v1.5.2", GitCommit:"269f928217957e7126dc87e6adfa82242bfe5b1e", GitTreeState:"clean", BuildDate:"2017-07-03T15:31:10Z", GoVersion:"go1.7.4", Compiler:"gc", Platform:"linux/amd64"} 3 Server Version: version.Info{Major:"1", Minor:"5", GitVersion:"v1.5.2", GitCommit:"269f928217957e7126dc87e6adfa82242bfe5b1e", GitTreeState:"clean", BuildDate:"2017-07-03T15:31:10Z", GoVersion:"go1.7.4", Compiler:"gc", Platform:"linux/amd64"} 4 [root@k8s-master ~]#
注意：k8s v1.5 web界面，kubernetes-dashboard v1.5 ，k8s的安装版本和kubernetes-dashboard的版本对应，此时对k8s了解还不是很深，只能一点点摸索了。
kubernetes dashboard镜像获取：docker pull registry.cn-hangzhou.aliyuncs.com/google-containers/kubernetes-dashboard-amd64:v1.5.0。
这里重新tag，并push到自己的私有镜像仓库了，命令如下所示：

然后将创建的Pod删除掉，修改deployment配置文件dashboard-deploy.yaml。
1 [root@k8s-master dashboard]# vim dashboard-deploy.yaml
修改内容，如下所示：
删除创建的delpoyment、svc。

访问路径，查看界面。http://192.168.110.133:8080/ui/
k8s的dashboard是k8s的一个web界面的工具，可以创建多种资源或者删除资源。注意，如果三台机器挂起之后，第二次直接启动，你的dashboard好像不能访问耶，我直接重启了三台机器就行了，因为我的所有组件服务都是设置的开机自启动，避免了一些麻烦。
使用k8s的dashboard创建资源来创建一个资源，有两种方式，第一种是按照规则填写，第二种是上传Json格式的文件。
可以看到，默认是Deployment，这个很多东西估计和自己的dashboard的版本有关，所以根据自己的情况进行判断即可。
接下来，可以多这个Deployment进行删除或者编辑配置文件，这里将它删除掉。
然后，可以将创建的Service删除掉，如下所示：
这里Replica Sets也删除掉，deployment并不像RC直接去启动Pod，它们之间的区别是deployment会启动一个RS，RS拥有RC的百分之九十的功能，比RC的功能还多一些。
此时，可以看到创建的两个Pod也就删除掉了。
