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. 访问dashboard用的是装有kubectl-proxy node节点的外网ip地址。
2. 安装完成后，经过安装有kubectl-proxy的机器的外网ip进行访问，访问的时候还须要输入证书内容，证书的内容经过命令来产生。

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}')
