I'm setting up a Kubernetes master node. Just the master node, no worker nodes for now.
Set up was completed without any issues using this tutorial. Now,
$kubectl get pods -o wide --all-namespaces
kube-system calico-kube-controllers-694687c474-96b7h 0/1 Pending 0 4h19m <none> <none> <none> <none>
kube-system coredns-86c58d9df4-dv847 0/1 Pending 0 4h28m <none> <none> <none> <none>

kube-system kubernetes-dashboard-57df4db6b-wlv86 0/1 Pending 0 3h55m <none> <none>
When I try to open the Kubernetes-dashboard using, http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/ in local browser, it fails to open the dashboard and I receive below error in the browser:
{
"kind": "Status",
"apiVersion": "v1",
"metadata": {
},
"status": "Failure",
"message": "no endpoints available for service \"kubernetes-dashboard\"",
"reason": "ServiceUnavailable",
"code": 503
}
I assume as the kubernetes-dashboard pod is pending, dashboard would not open. How do I get it to work for me?
Any help is appreciated.
You can do kubectl describe pod kubernetes-dashboard-57df4db6b-wlv86
and the output should tell you why the Pod couldn't be scheduled. There can be different reasons and kubernetes 'debug pods' guide covers several of them. The most common is insufficient resources but it could be other things, especially on a new cluster. I notice the DNS pods are also pending - I'd suggest looking at those first as you need networking to run applications.
