-Dashboard is a web-based Kubernetes user interface. You can use Dashboard to deploy containerized applications to a Kubernetes cluster, troubleshoot your containerized application, and manage the cluster itself along with its attendant resources. You can use Dashboard to get an overview of applications running on your cluster, as well as for creating or modifying individual Kubernetes resources (such as Deployments, Jobs, DaemonSets, etc). For example, you can scale a Deployment, initiate a rolling update, restart a pod or deploy new applications using a deploy wizard.

 ## Accessing the Dashboard UI
 
-There are multiple ways you can access the Dashboard UI; either by using the kubectl command-line interface, or by accessing the Kubernetes master apiserver using your web browser.
+To protect your cluster data, Dashboard deploys with a minimal RBAC configuration by default. Currently, Dashboard only supports logging in with a Bearer Token. To create a token for this demo, you can follow our guide on [creating a sample user](https://github.com/kubernetes/dashboard/wiki/Creating-sample-user).

-### Master server
-You may access the UI directly via the Kubernetes master apiserver. Open a browser and navigate to ``https://<master-ip>:<apiserver-port>/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/``, where `<master-ip>` is IP address or domain name of the Kubernetes

-Please note, this works only if the apiserver is set up to allow authentication with username and password. This is not currently the case with some setup tools (e.g., `kubeadm`). Refer to the  [authentication admin documentation](/docs/reference/access-authn-authz/authentication/) for information on how to configure authentication manually.

-If the username and password are configured but unknown to you, then use `kubectl config view` to find it.

 Dashboard shows most Kubernetes object kinds and groups them in a few menu categories.
 
-#### Admin
-View for cluster and namespace administrators. It lists Nodes, Namespaces and Persistent Volumes and has detail views for them. Node list view contains CPU and memory usage metrics aggregated across all Nodes. The details view shows the metrics for a Node, its specification, status, allocated resources, events and pods running on the node.

 #### Workloads
-Entry point view that shows all applications running in the selected namespace. The view lists applications by workload kind (e.g., Deployments, Replica Sets, Stateful Sets, etc.) and each workload kind can be viewed separately. The lists summarize actionable information about the workloads, such as the number of ready pods for a Replica Set or current memory usage for a Pod.
