CoreDNS和Dashboard部署

1.建立CoreDNS

[root@linux-node1 ~]# kubectl create -f coredns.yaml 

[root@linux-node1 ~]# kubectl get pod -n kube-system
NAME                                    READY     STATUS    RESTARTS   AGE
coredns-77c989547b-9pj8b                1/1       Running   0          6m
coredns-77c989547b-kncd5                1/1       Running   0          6m

2.建立Dashboard

ps:node

1. 訪問dashboard用的是裝有kubectl-proxy node節點的外網ip地址。
2. 安裝完成後，經過安裝有kubectl-proxy的機器的外網ip進行訪問，訪問的時候還須要輸入證書內容，證書的內容經過命令來產生。

dashboard yaml文件地址: https://github.com/unixhot/salt-kubernetes/tree/master/addons/dashboardlinux

[root@linux-node1 ~]# kubectl create -f 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'.

kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin-user | awk '{print $1}')
