Kubernetes Dashboard

创建Dashboard

[root@linux-node1 ~]# kubectl create -f /srv/addons/dashboard/
[root@linux-node1 ~]# kubectl cluster-info
Kubernetes master is running at https://192.168.56.11:6443
kubernetes-dashboard is running at https://192.168.56.11:6443/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

查看Dashboard信息

#发现Dashboard是运行在node3节点
[root@linux-node1 ~]# kubectl get pod -n kube-system -o wide
NAME                                    READY     STATUS    RESTARTS   AGE       IP          NODE
kubernetes-dashboard-66c9d98865-bqwl5   1/1       Running   0          1h        10.2.76.3   192.168.56.13

#查看Dashboard运行日志
[root@linux-node1 ~]# kubectl logs pod/kubernetes-dashboard-66c9d98865-bqwl5 -n kube-system

#查看Dashboard服务IP(可以访问任意node节点的34696端口就可以访问到Dashboard页面 https://192.168.56.13:34696/#!/overview?namespace=default,如何master节点安装了kube-proxy也可以访问)
[root@linux-node1 ~]# kubectl get service -n kube-system
NAME                   TYPE       CLUSTER-IP   EXTERNAL-IP   PORT(S)         AGE
kubernetes-dashboard   NodePort   10.1.36.42   <none>        443:34696/TCP   1h
