k8s的WEB介面部署

兩個master節點檢查pod資源是否正常

[root@localhost ~]# kubectl get nodes  '//檢查node節點是否執行正常'
NAME             STATUS   ROLES    AGE   VERSION
192.168.136.30   Ready    <none>   15h   v1.12.3
192.168.136.40   Ready    <none>   15h   v1.12.3
[root@master ~]# kubectl get pods	'//檢查之前建立的pod資源是否執行正常'
NAME                    READY   STATUS    RESTARTS   AGE
nginx-dbddb74b8-5s6h7   1/1     Running   0          7d8h

master節點上建立dashboard工作目錄，並拷貝部署web介面所需的檔案到指定目錄

• 下載的網址（直接複製即可）：https://github.com/kubernetes/kubernetes/tree/master/cluster/addons/dashboard

在master01上操作

建立dashborad工作目錄

[root@localhost k8s]# mkdir dashboard

[root@localhost k8s]# cd /root/k8s/dashboard/
[root@localhost dashboard]# ls
dashboard-configmap.yaml   dashboard-rbac.yaml    dashboard-service.yaml
dashboard-controller.yaml  dashboard-secret.yaml  k8s-admin.yaml

configmap.yaml：設定，deployment.yaml：控制器，rbac.yaml：角色控制，存取控制，secret.yaml：安全，service.yaml：服務’

我們檢視一下里面的內容

[root@localhost dashboard]# vim dashboard-rbac.yaml 

建立資源（順序不可以亂）

1：建立rbac.yaml：角色控制

[root@localhost dashboard]# kubectl create -f dashboard-rbac.yaml 

2：建立secret.yaml：安全

[root@localhost dashboard]# kubectl create -f dashboard-secret.yaml

3：建立configmap.yaml：設定

[root@localhost dashboard]# kubectl create -f dashboard-configmap.yaml 

4：建立controller

[root@localhost dashboard]# kubectl create -f dashboard-controller.yaml 

5：建立service

[root@localhost dashboard]# kubectl create -f dashboard-service.yaml

檢視資源是否被建立

[root@localhost dashboard]# kubectl get pods -n kube-system
NAME                                    READY   STATUS    RESTARTS   AGE
kubernetes-dashboard-7dffbccd68-jmbgg   1/1     Running   1          10h

檢視所有建立的資源

[root@localhost dashboard]# kubectl get role -n kube-system
[root@localhost dashboard]# kubectl get Secret -n kube-system
[root@localhost dashboard]# kubectl get ConfigMap -n kube-system
[root@localhost dashboard]# kubectl get  ServiceAccount -n kube-system
[root@localhost dashboard]# kubectl get Service -n kube-system 

檢視server資源和pods資源

kubectl get pods,svc -n kube-system

檢視地址

 kubectl get pods -n kube-system -o wide（檢視pod資源）
 kubernetes-dashboard-7dffbccd68-jmbgg   1/1     Running   1          10h   172.17.38.2   192.168.136.40   <none>

建立簽名證書

[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

建立證書

先刪除資源
kubectl delete secret kubernetes-dashboard-certs -n kube-system
建立證書
kubectl create secret generic kubernetes-dashboard-certs --from-file=./ -n kube-system

執行指令

bash dashboard-cert.sh /root/k8s/k8s-cert/

自簽證書

[root@localhost dashboard]# vim dashboard-controller.yaml

 47           - --auto-generate-certificates 下面新增
 48        -    --tls-key-file=dashboard-key.pem
 49           - --tls-cert-file=dashboard.pem

重新部署

 kubectl apply -f dashboard-controller.yaml

如果上面命令無法操作請嘗試下面

 kubectl delete -f dashboard-controller.yaml
 kubectl create -f dashboard-controller.yaml

在次存取出現點選繼續存取

生成令牌

[root@localhost dashboard]# kubectl create -f k8s-admin.yaml 

儲存

[root@localhost dashboard]# kubectl get secret -n kube-system
