message: "services "kubernetes-dashboard" not found", - kubernetes

Question

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

The docs are probably not updated. Since the service is created in kube-system namespace you can use below
http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/
