Kubernetes Dashboard Installation

Kubernetes Dashboard deployed on Master Node

To avoid running the Dashboard on worker nodes, the following command needs to be launched before any worker nodes joining the cluster: (It is important to note that the hyperlink in the original video is not working, the following instruction has been tested as of July 21, 2021)

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.2.0/aio/deploy/recommended.yaml

A service account must be created to make dashboard available

kubectl create serviceaccount dashboard -n default 

Then, it needs to create the dashboard-admin

kubectl create clusterrolebinding dashboard-admin -n default --clusterrole=cluster-admin --serviceaccount=default:dashboard

Then, one needs to get the secret key to be pasted into the web-based interface of Kubernetes Dashboard.

kubectl get secret $(kubectl get serviceaccount dashboard -o jsonpath="{.secrets[0].name}") -o jsonpath="{.data.token}" | base64 --decode

This will generate a long token string, something like this:
