Kubernetes is an advanced container orchestration platform, but operating it via the command line may be difficult, particularly for novices. The Kubernetes Dashboard is a simple web-based GUI that allows you to monitor and manage your cluster effectively. This guide will walk you through the steps of installing and using the Kubernetes Dashboard in your cluster.

Requirements

• A running Kubernetes cluster
• Install and setup kubectl CLI to interface with your cluster.
• Administrative access to deploy and manage resources in the cluster

Step 1 – Deploy the Kubernetes Dashboard

To install the Kubernetes Dashboard, apply the official YAML manifest:

kubectl apply -f

https://raw.githubusercontent.com/kubernetes/dashboard/v2.7.0/aio/deploy/recomme nded.yaml

This command deploys the essential components, such as the dashboard UI, metrics server, and associated configurations.

Step 2 – Create an Admin Service Account

By default, the dashboard has limited permissions. Create a service account with cluster-wide administrative privileges to completely access and control the cluster.

Create a new YAML file (for example, admin-service-account.yaml) containing the following content:

apiVersion: v1
kind: ServiceAccount
metadata:
 name: admin-user
 namespace: kubernetes-dashboard
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
 name: admin-user
roleRef:
 apiGroup: rbac.authorization.k8s.io
 kind: ClusterRole
 name: cluster-admin
subjects:
- kind: ServiceAccount
 name: admin-user
 namespace: kubernetes-dashboard

Apply this configuration:

kubectl apply -f admin-service-account.yaml

Step 3 – Retrieve the Access Token

Once the service account is created, retrieve its access token to authenticate with the dashboard:

kubectl -n kubernetes-dashboard create token admin-user

Copy and save the token as you will need it to log in to the dashboard.

Step 4 – Access the Kubernetes Dashboard

To access the dashboard, start a proxy server:

kubectl proxy

Now, open the following URL in your browser:

http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/ht tps:kubernetes-dashboard:/proxy/

Step 5 – Log in to the Dashboard

When prompted, select the Token authentication method and paste the token retrieved earlier. Click Sign In to access the dashboard.

Conclusion

The Kubernetes Dashboard simplifies monitoring and managing your cluster by making it easy to deploy applications, inspect logs, and control resources. These instructions mentioned above will allow you to safely configure and access the dashboard in your Kubernetes system.
