k8s网站页面--kubernetes dashboard仪表盘

前面我们做了k8s的多节点实验
下面是k8s的网站管理页面的部署

//在master01上操作
//创建dashborad工作目录
[root@localhost k8s]# mkdir dashboard
//拷贝官方的文件
https://github.com/kubernetes/kubernetes/tree/master/cluster/addons/dashboard

这个yaml文件里面包含了网站的一些pod资源：

我把他分成了5个yaml文件，也可以放在一个yaml文件中创建
[root@localhost dashboard]# ls
dashboard-configmap.yaml   dashboard-rbac.yaml    dashboard-service.yaml
dashboard-controller.yaml  dashboard-secret.yaml  k8s-admin.yaml
[root@localhost dashboard]# kubectl create -f dashboard-rbac.yaml  ##授权管理文件
role.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
[root@localhost dashboard]# kubectl create -f dashboard-secret.yaml  ##证书验证文件
secret/kubernetes-dashboard-certs created
secret/kubernetes-dashboard-key-holder created
[root@localhost dashboard]# kubectl create -f dashboard-configmap.yaml ##配置文件
configmap/kubernetes-dashboard-settings created
[root@localhost dashboard]# kubectl create -f dashboard-controller.yaml  ##控制器资源
serviceaccount/kubernetes-dashboard created
deployment.apps/kubernetes-dashboard created
[root@localhost dashboard]# kubectl create -f dashboard-service.yaml  ##服务资源
service/kubernetes-dashboard created
//完成后查看创建在指定的kube-system命名空间下
[root@localhost dashboard]# kubectl get pods -n kube-system
NAME                                    READY   STATUS              RESTARTS   AGE

//查看如何访问
[root@localhost dashboard]# kubectl get pods,svc -n kube-system

service/kubernetes-dashboard   NodePort   10.0.0.243   <none>        443:30001/TCP   2m24s

//访问nodeIP就可以访问
https://192.168.130.20:30001/

如果是火狐浏览器的话，直接就可以登录，但是谷歌不行，需要自己做个证书验证，才能登录
解决办法：

[root@localhost dashboard]# vim dashboard-cert.sh
cat > dashboard-csr.json <<EOF
{
   "CN": "Dashboard",
   "hosts": [],
   "key": {
       "algo": "rsa",
       "size": 2048
   },
   "names": [
       {
           "C": "CN",
           "L": "BeiJing",
           "ST": "BeiJing"
       }
   ]
}
EOF

K8S_CA=$1
cfssl gencert -ca=$K8S_CA/ca.pem -ca-key=$K8S_CA/ca-key.pem -config=$K8S_CA/ca-config.json -profile=kubernetes dashboard-csr.json | cfssljson -bare dashboard
kubectl delete secret kubernetes-dashboard-certs -n kube-system
kubectl create secret generic kubernetes-dashboard-certs --from-file=./ -n kube-system
[root@localhost dashboard]# vim dashboard-controller.yaml  ##增加证书两行，然后apply

#        - --tls-key-file=dashboard-key.pem   ##增加2行
#        - --tls-cert-file=dashboard.pem    ##增加
[root@localhost dashboard]# bash dashboard-cert.sh /root/k8s/k8s-cert/
//重新部署
[root@localhost dashboard]# kubectl delete -f dashboard-controller.yaml 
[root@localhost dashboard]# kubectl apply -f dashboard-controller.yaml
