一.k8s图形化

# 1.下载镜像导入

[root@node-2 ~]# docker load < metrics-scraper.v1.0.4.tar.gz
[root@node-2 ~]# docker load < dashboard.v2.0.0.tar.gz

#2.修改资源清单的nodeport，指定启动节点然后应用

 39 spec:
 40   type: NodePort
 41   ports:
 42     - port: 443
 43       targetPort: 8443
 44       nodePort: 31000
 45   selector:
 46     k8s-app: kubernetes-dashboard

273     spec:
274       nodeName: node-2
275       containers:
276         - name: dashboard-metrics-scraper
277           image: kubernetesui/metrics-scraper:v1.0.4
278           imagePullPolicy: IfNotPresent

[root@master-1 ~]# kubectl apply -f recommended-2.0.yaml
[root@master-1 ~]# kubectl get pod -o wide -n kubernetes-dashboard

dashboard-metrics-scraper-86bc87dc46-cgjbf   1/1     Running   0          59s   10.2.1.76   node-2     <none>           <none>
kubernetes-dashboard-79658c479c-nbf2k        1/1     Running   0          60s   10.2.0.19   master-1   <none>           <none>

#3.授权
[root@master-1 ~]# kubectl create serviceaccount dashboard-admin -n kubernetes-dashboard

[root@master-1 ~]# kubectl create clusterrolebinding \
dashboard-admin --clusterrole=cluster-admin --serviceaccount=kubernetes-dashboard:dashboard-admin

# 4.获取token
[root@master-1 ~]# kubectl describe secrets \
-n kubernetes-dashboard $(kubectl -n kubernetes-dashboard get secret | awk '/dashboard-admin/{print $1}')
