centos7 搭建 kubernetes1.16.7 集群 III ( dashboard & metrics-server )

换应用镜像（毕设原因）

将 mediawiki换成 rubis，具体步骤和装mediaWiki一样，rubis镜像： mcabranches/rubis-app 

如下图：

 

装 dashboard

在　　https://github.com/kubernetes/dashboard/releases　　中找到和k8s版本对应的版本。

1 # 这里先 wget 到本地 
2 [root@k8s-master dashboard]# wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-beta7/aio/deploy/recommended.yaml
 1 # 对 recommended.yaml 部分代码进行更改
 2 # 首先是 kubernetes-dashboard 的 Service，将访问方式改为 NodePort
 3 kind: Service
 4 apiVersion: v1
 5 metadata:
 6   labels:
 7     k8s-app: kubernetes-dashboard
 8   name: kubernetes-dashboard
 9   namespace: kubernetes-dashboard
10 spec:
11   type: NodePort
12   ports:
13     - port: 443
14       targetPort: 8443
15   selector:
16     k8s-app: kubernetes-dashboard
17 
18 # 其次是 kubernetes-dashboard 的 Deployment
19 # 我将镜像先pull到了本地，将 imagePullPolicy 改为 IfNotPresent，不从网上拉
20 # args 中加入    - --token-ttl=43200 ，延长 token 过期时间
21  spec:
22       containers:
23         - name: kubernetes-dashboard
24           image: kubernetesui/dashboard:v2.0.0-beta7
25           imagePullPolicy: IfNotPresent      
26           ports:
27             - containerPort: 8443
28               protocol: TCP
29           args:
30             - --auto-generate-certificates
31             - --namespace=kubernetes-dashboard
32             - --token-ttl=43200
33 #对于 dashboard-metrics-scraper 的 deployment ，也先pull image到本地，将 imagePullPolicy 改为 IfNotPresent
34 spec:
35       containers:
36         - name: dashboard-metrics-scraper
37           image: kubernetesui/metrics-scraper:v1.0.2
38           imagePullPolicy: IfNotPresent

16 
17 # kubectl get svc --all-namespaces 获取 dashboard 的 port，就可以访问了
18 # 使用filefox ，以及https
19 
20 # 获取 tocken
21 [root@k8s-master dashboard]#   kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin-user | awk '{print $1}')
