kubernetes - 访问 kubernetes ui 时未找到服务 "kubernetes-dashboard"

Question

我正在使用以下命令部署 kubernetes UI:

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml

启动代理:

kubectl proxy --address='172.19.104.231' --port=8001 --accept-hosts='^*$'

访问用户界面:

curl http://172.19.104.231:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/
http://kubernetes.example.com/api/v1/namespaces/kube-system/services/kube-ui/#/dashboard/

日志输出:

[root@iZuf63refzweg1d9dh94t8Z ~]# curl http://172.19.104.231:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/
{
  "kind": "Status",
  "apiVersion": "v1",
  "metadata": {

  },
  "status": "Failure",
  "message": "services \"kubernetes-dashboard\" not found",
  "reason": "NotFound",
  "details": {
    "name": "kubernetes-dashboard",
    "kind": "services"
  },
  "code": 404}

如何解决问题？检查 Pod 状态:

[root@iZuf63refzweg1d9dh94t8Z ~]# kubectl get pod --namespace=kube-system
NAME                                    READY   STATUS    RESTARTS   AGE
kubernetes-dashboard-7d75c474bb-b2lwd   0/1     Pending   0          34h

如果您使用 K8S 仪表板 v2.0.0-betax，

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-beta8/aio/deploy/recommended.yaml

然后使用它来访问仪表板:

http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/

如果您使用 K8S 仪表板 v1.10.1，

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml

然后使用它来访问仪表板:

http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/

我也遇到了同样的问题，但后来我意识到仪表板 v2.0.0-betax 和 v1.10.1 使用不同的命名空间。最新版本使用 kubernetes-dashboard 命名空间，但旧版本使用 kube-system 命名空间
