没有可用于服务的终结点 [英] no endpoints available for service \"kubernetes-dashboard\"

问题描述

我正在尝试遵循 GitHub-kubernetes/dashboard:Kubernetes集群的通用Web UI.

部署/访问:

# export KUBECONFIG=/etc/kubernetes/admin.conf
# kubectl create -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml
secret/kubernetes-dashboard-certs created
serviceaccount/kubernetes-dashboard created
role.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
deployment.apps/kubernetes-dashboard created
service/kubernetes-dashboard created
# kubectl proxy
Starting to serve on 127.0.0.1:8001

卷曲:

# curl http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/
{
  "kind": "Status",
  "apiVersion": "v1",
  "metadata": {

  },
  "status": "Failure",
  "message": "no endpoints available for service \"kubernetes-dashboard\"",
  "reason": "ServiceUnavailable",
  "code": 503
}# 

请告知.

推荐答案

您似乎正在尝试利用 kubeadm 部署Kubernetes，但跳过了

It would appear that you are attempting to deploy Kubernetes leveraging kubeadm but have skipped the step of Installing a pod network add-on (CNI). Notice the warning:

必须在任何应用程序之前部署网络.另外，在安装网络之前，CoreDNS将不会启动.kubeadm仅支持基于容器网络接口(CNI)的网络(不支持kubenet).

The network must be deployed before any applications. Also, CoreDNS will not start up before a network is installed. kubeadm only supports Container Network Interface (CNI) based networks (and does not support kubenet).

执行此操作后，CoreDNS吊舱将正常运行.可以通过以下方式验证: kubectl -n kube-system -l = k8s-app = kube-dns获取Pod

Once you do this, the CoreDNS pods should come up healthy. This can be verified with: kubectl -n kube-system -l=k8s-app=kube-dns get pods

然后， kubernetes-dashboard 窗格也应该正常运行.

Then the kubernetes-dashboard pod should come up healthy as well.
