To run Kubernetes dashboard, we simply fire a command to apply a configuration file, and every resource is created automatically:

$ kubectl create -f
https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml
secret "kubernetes-dashboard-certs" created
serviceaccount "kubernetes-dashboard" created
role "kubernetes-dashboard-minimal" created
rolebinding "kubernetes-dashboard-minimal" created
deployment "kubernetes-dashboard" created
service "kubernetes-dashboard" created

Next, let's use the command kubectl proxy to open a gateway connecting localhost and the API server. Then, we are good to access the dashboard via a browser:

$ kubectl proxy
Starting to serve on 127.0.0.1:8001

Once you see a halting result showing, as in the preceding code, you can now access the dashboard by URL: http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/. There, you will see the following screen in your browser:

To step into our demonstration quickly, we will take the token of an existed service account to log in with. No matter what booting tool you use, leveraging the one created by the dashboard is suitable in every case:

// check the service account in your system
$ kubectl get secret -n kube-system
NAME                               TYPE                                  DATA      AGE
default-token-7jfmd                kubernetes.io/service-account-token   3         51d
kubernetes-dashboard-certs         Opaque                                0         2d

kubernetes-dashboard-token-jw42n   kubernetes.io/service-account-token   3         2d
// grabbing token by checking the detail information of the service account with prefix "kubernetes-dashboard-token-"
$ kubectl describe secret kubernetes-dashboard-token-jw42n -n kube-system

Copy the token and paste it into console on the browser, then, click SIGN IN:
