Un Dahboardable to access the Kubernete

[venkatesh]

Hi All,

After installed Kubernetes. I am unable to access the Dashboard. the moment when I hit the master ip :8080/ui in the browser, below is output we are getting

{
  "kind": "Status",
  "apiVersion": "v1",
  "metadata": {},
  "status": "Failure",
  "message": "no endpoints available for service \"kubernetes-dashboard\"",
  "reason": "ServiceUnavailable",
  "code": 503
}

Also unable to download the  kubectl create -f https://rawgit.com/kubernetes/dashboard/master/src/deploy/kubernetes-dashboard.yaml  file

output: [root@kubernetesmaster ~]# kubectl create -f https://rawgit.com/kubernetes/dashboard/master/src/deploy/kubernetes-dashboard.yaml --validate=false
Error from server (AlreadyExists): error when creating "https://rawgit.com/kubernetes/dashboard/master/src/deploy/kubernetes-dashboard.yaml": serviceaccounts "kubernetes-dashboard" already exists
Error from server (BadRequest): error when creating "https://rawgit.com/kubernetes/dashboard/master/src/deploy/kubernetes-dashboard.yaml": ClusterRoleBinding in version "v1beta1" cannot be handled as a ClusterRoleBinding: no kind "ClusterRoleBinding" is registered for version "rbac.authorization.k8s.io/v1beta1"

Error from server (AlreadyExists): error when creating "https://rawgit.com/kubernetes/dashboard/master/src/deploy/kubernetes-dashboard.yaml": services "kubernetes-dashboard" already exists

Please help me.

Thanks,

It looks like you're running an older version of Kubernetes that doesn't support RBAC. If that's the case, then install the dashboard version for your version, e.g.

  kubectl create -f https://git.io/kube-dashboard-no-rbac

Hi Remon,

Kubernetes version is 1.5.2 

[root@kubernetesmaster ~]# kubectl --version

Kubernetes v1.5.2

[root@kubernetesmaster ~]#

which you provided the link also same getting error message

[root@kubernetesmaster ~]#  kubectl create -f https://git.io/kube-dashboard-no-rbac

Error from server (AlreadyExists): error when creating "https://git.io/kube-dashboard-no-rbac": deployments.extensions "kubernetes-dashboard" already exists

Error from server (AlreadyExists): error when creating "https://git.io/kube-dashboard-no-rbac": services "kubernetes-dashboard" already exists

I checked in current directory no file with the name of kubernetes-dashboard. then why we are getting an error message?

Help on this, almost I am working 3 days on this issue. still the issue is open.

Thanks,

Venkatesh

The "already exists" errors is because you've previously tried to create the dashboard. You should delete it first, then try again.
