Kubernetes Dashboard docs ( https://kubernetes.io/docs/tasks/access-application-cluster/web-ui-dashboard/ ) say: Kubectl will make Dashboard available at http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/. but I get this when using that URL:

{
kind: "Status",
apiVersion: "v1",
metadata: { },
status: "Failure",
message: "services "kubernetes-dashboard" not found",
reason: "NotFound",
details: {
name: "kubernetes-dashboard",
kind: "services"
},
code: 404
}

FYI

[vagrant@master ~]$ kubectl get all -n kube-system
