Kubernetes Dashboard Setup Explained

Kubernetes Dashboard Setup Explained

Kubernetes, an open-source container orchestration platform, has revolutionized the way we deploy, scale, and manage containerized applications. One of the key tools in the Kubernetes ecosystem is the Kubernetes Dashboard, a web-based user interface that provides a graphical representation of your cluster. In this guide, we'll walk you through the step-by-step process of setting up the Kubernetes Dashboard, enabling you to efficiently monitor and manage your Kubernetes clusters.


Before we dive into the setup process, make sure you have the following prerequisites in place:

  1. A running Kubernetes cluster.
  2. kubectl, the Kubernetes command-line tool, installed on your local machine.
  3. Cluster-admin permissions to deploy the necessary resources.

Step 1: Install the Kubernetes Dashboard

To begin, you need to install the Kubernetes Dashboard using kubectl. Open your terminal and run the following command:

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.3.1/aio/deploy/recommended.yaml

This command deploys the necessary resources for the Kubernetes Dashboard, including the deployment, service account, and role-based access control (RBAC) configuration.

Step 2: Create a Service Account

For security reasons, it is recommended to create a service account dedicated to the Kubernetes Dashboard. Execute the following commands to create a service account and bind it to the cluster-admin role:

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

Step 3: Access the Kubernetes Dashboard

Once the installation is complete, you can access the Kubernetes Dashboard using kubectl. Run the following command to get the authentication token:

kubectl -n kubernetes-dashboard describe secret $(kubectl -n kubernetes-dashboard get secret | grep dashboard-admin-sa-token | awk '{print $1}')

Copy the token from the output and use it to log in to the Kubernetes Dashboard. To access the dashboard, run the following command:

kubectl proxy

Open your web browser and navigate to http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/.

Step 4: Explore the Kubernetes Dashboard

Congratulations! You've successfully set up the Kubernetes Dashboard. Explore the various tabs and functionalities it offers, such as viewing nodes, pods, deployments, and services. The dashboard provides valuable insights into the health and performance of your Kubernetes cluster.

More Examples:

For advanced users, the Kubernetes Dashboard offers additional features such as resource metrics, custom metrics, and application logs. Explore these capabilities to gain a deeper understanding of your cluster's behavior.

Feel free to tailor the steps based on your specific Kubernetes setup and requirements. This guide provides a solid foundation for deploying the Kubernetes Dashboard, allowing you to leverage its capabilities for efficient cluster management.
