I am trying to setup Kubernetes on Ubuntu 18.04 by following this article.

Everything works fine but when I am trying to access local Kubernetes dashboard then it shows empty and nothing is visible like pods,services & deployments.

However when I am running

I already ran following commands

gt; kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-beta8/aio/deploy/recommended.yaml

gt; kubectl proxy

Am I missing any configuration here? Any suggestions to fix this issue?

gt; kubectl get pods --all-namespaces
NAMESPACE              NAME                                         READY   STATUS    RESTARTS   AGE

kubernetes-dashboard   dashboard-metrics-scraper-76585494d8-4rrdp   1/1     Running   3          46h
kubernetes-dashboard   kubernetes-dashboard-5996555fd8-sxgxf        1/1     Running   16         46h

After looking at the notification section, found these errors

1. events is forbidden: User "system:serviceaccount:kubernetes-dashboard:admin-user" cannot list resource "events" in API group "" in the namespace "default"

2. pods is forbidden: User "system:serviceaccount:kubernetes-dashboard:admin-user" cannot list resource "pods" in API group "" in the namespace "default"

Update 1:

its working now after applying RBAC kubectl apply -f filename.yml
