How to access Kubernetes Dashboard via web browser?

Accessing Kubernetes Dashboard via Web Browser

The Kubernetes Dashboard is a web-based user interface for managing and troubleshooting your Kubernetes cluster. It provides a comprehensive overview of the cluster's state, including the running applications, resource utilization, and configuration details. Accessing the Kubernetes Dashboard through a web browser can be a convenient way to interact with your cluster, especially for users who prefer a graphical interface over the command-line.

Prerequisites

Before you can access the Kubernetes Dashboard, you need to ensure that the following prerequisites are met:

1. Kubernetes Cluster: You must have a running Kubernetes cluster. This can be a local cluster, such as minikube or Docker Desktop, or a cloud-hosted Kubernetes service, like Google Kubernetes Engine (GKE), Amazon Elastic Kubernetes Service (EKS), or Azure Kubernetes Service (AKS).

2. Kubernetes Dashboard Deployment: The Kubernetes Dashboard must be deployed and running in your cluster. In most cases, the dashboard is installed by default when you create a new Kubernetes cluster, but you can also manually deploy it if necessary.

3. Access Permissions: You must have the necessary permissions to access the Kubernetes Dashboard. This typically involves having a Kubernetes user account with the appropriate role-based access control (RBAC) permissions.

Accessing the Kubernetes Dashboard

There are several ways to access the Kubernetes Dashboard, depending on your deployment and configuration. Here are the general steps:

1. Accessing the Dashboard Locally:

   • If you're running a local Kubernetes cluster, such as minikube or Docker Desktop, you can access the dashboard by running the following command:

     kubectl proxy

   • This will start a proxy server that allows you to access the dashboard at http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/.
   • Open your web browser and navigate to the URL provided by the kubectl proxy command.

2. Accessing the Dashboard Remotely:

   • If you're using a cloud-hosted Kubernetes service, you'll need to configure the dashboard to be accessible from outside your cluster.
   • The specific steps may vary depending on your cloud provider, but generally, you'll need to:
     • Expose the Kubernetes Dashboard service as a LoadBalancer or NodePort service.
     • Obtain the external IP address or URL of the exposed service.
   • Once you have the external access details, you can open your web browser and navigate to the provided URL to access the Kubernetes Dashboard.

3. Authenticating with the Dashboard:

   • When you first access the Kubernetes Dashboard, you may be prompted to authenticate.
   • The authentication method may vary depending on your Kubernetes cluster configuration, but common options include:
     • Token-based authentication: You'll need to provide a valid Kubernetes user token.
     • Kubeconfig-based authentication: You can use your local Kubeconfig file to authenticate.
   • Follow the instructions provided on the dashboard login page to authenticate and gain access to the Kubernetes Dashboard.

Once you've accessed the Kubernetes Dashboard, you'll be able to view and manage your Kubernetes resources, such as deployments, pods, services, and more, through the web-based interface.

Visualizing Kubernetes Concepts with Mermaid

To better understand the relationship between the Kubernetes Dashboard and the underlying Kubernetes cluster, let's use a Mermaid diagram:

In this diagram, we can see that the Kubernetes Dashboard is a separate component that connects to the Kubernetes API server to retrieve and display information about the cluster. The user can then interact with the cluster through the web-based interface provided by the Kubernetes Dashboard.

By understanding this relationship, you can better appreciate how the Kubernetes Dashboard fits into the overall Kubernetes ecosystem and how it can be used to simplify the management and monitoring of your Kubernetes applications.
