Kubernetes provides a Dashboard, to allow cluster management through a user interface, certainly more intuitive than the classic command line. You can use Dashboard to deploy containerized applications on a Kubernetes cluster, troubleshoot the containerized application, and manage cluster resources. You can use the Dashboard to get an overview of the applications running on the cluster, as well as to create or modify individual Kubernetes resources. For more information, consult the official documentation Kubernetes Dashboard.

Installation

The user interface is not distributed by default. Installation is very simple, just run the following command (check the version)

$ kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.1.0/aio/deploy/recommended.yaml

Access

We need to make a small modification to a .yaml file, via the command

...

$ kubectl -n kubernetes-dashboard get services
NAME                        TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)         AGE
dashboard-metrics-scraper   ClusterIP   10.106.152.1   <none>        8000/TCP        3d
kubernetes-dashboard        NodePort    10.101.35.23   <none>        443:30000/TCP   3d

Account and token

By connecting to the browser at https://<node_FIP>:<port>, in our case https://131.154.97.163:30000 (note the adoption of the protocol for secure communication with https), we could access the dashboard. There is no need to activate the VPN. The credentials entry screen will appear. As you can see, there are two ways of accessing: via token or via a configuration file. Here we deal with the first mode. However, it is advisable to try the connection to the dashboard, to make sure that the procedure carried out so far is correct.
