关于kubernetes:Kubernetes-Dashboard部署

jiezi

下载

先从官网把部署 Kubernetes Dashboard 的 yaml 下载到本地。

wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.7.0/aio/deploy/recommended.yaml

PS：如果因为墙了，本人想方法，总之先下载下来。

部署

执行上面的命令进行 Kubernetes Dashboard 部署

kubectl apply -f ./recommended.yaml

执行之后输入以下信息，示意曾经部署胜利

namespace/kubernetes-dashboard created
serviceaccount/kubernetes-dashboard created
service/kubernetes-dashboard created
secret/kubernetes-dashboard-certs created
secret/kubernetes-dashboard-csrf created
secret/kubernetes-dashboard-key-holder created
configmap/kubernetes-dashboard-settings created
role.rbac.authorization.k8s.io/kubernetes-dashboard created
clusterrole.rbac.authorization.k8s.io/kubernetes-dashboard created
rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created
clusterrolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created
deployment.apps/kubernetes-dashboard created
service/dashboard-metrics-scraper created
deployment.apps/dashboard-metrics-scraper created

查问一下 pod 和 service 是否都曾经创立

  • 查问 kubernetes-dashboard 命名空间下全副 pod
    kubectl get pods -n kubernetes-dashboard
NAME                                         READY   STATUS    RESTARTS   AGE
dashboard-metrics-scraper-64bcc67c9c-6hbv5   1/1     Running   0          4m
kubernetes-dashboard-5c8bd6b59-mm7gh         1/1     Running   0          4m
  • 查问 kubernetes-dashboard 命名空间下全副 service
    kubectl get svc -n kubernetes-dashboard
NAME                        TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)         AGE
dashboard-metrics-scraper   ClusterIP   10.102.13.19     <none>        8000/TCP        4m22s
kubernetes-dashboard        ClusterIP   10.109.154.224   <none>        443:/TCP        4m22s

能够看到 service 的 TYPE 是 ClusterIP：只对集群外部可见，内部无法访问。NodePort：才可对外部可见。
因而然而 443 端口仍是外部才能够拜访的，咱们机器无法访问，因而须要将 443 端口映射进去。

映射端口让内部能够拜访

执行一下命令，即可随机调配一个 30000+ 的端口映射 443 即 https 端口

kubectl patch svc kubernetes-dashboard -p '{"spec":{"type":"NodePort"}}' -n kubernetes-dashboard

执行后，咱们再执行
kubectl get svc -n kubernetes-dashboard

NAME                        TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)         AGE
dashboard-metrics-scraper   ClusterIP   10.102.13.19     <none>        8000/TCP        4m22s
kubernetes-dashboard        NodePort    10.109.154.224   <none>        443:31767/TCP   4m22s

曾经将 kubernetes-dashboard 的 service TYPE 改为了 NodePort，内部端口是 31767。

实现

浏览器关上：https://localhost:31767/
如果 Chrome/Edge 提醒不平安，你就在页面出，盲敲 thisisunsafe，就能够进入。

到此为止就能够进入 kubernetes-dashboard。
