How to install Web UI (Dashboard)

According to the Kubernetes documentation:

"Dashboard is a web-based Kubernetes user interface. You can use Dashboard to deploy containerized applications to a Kubernetes cluster, troubleshoot your containerized applications, and manage the cluster resources."

Below is a step-by-step guide on installing the Kubernetes Dashboard and accessing it using a token issued in the customer portal.

Deploying the Kubernetes Dashboard

1. Install Helm
2. Add the Kubernetes Dashboard repository:

    helm repo add kubernetes-dashboard https://kubernetes.github.io/dashboard/

3. Deploy the Kubernetes Dashboard:

    helm upgrade --install kubernetes-dashboard kubernetes-dashboard/kubernetes-dashboard --create-namespace --namespace kubernetes-dashboard

The Kubernetes Dashboard will now be deployed in your cluster.

Accessing the Dashboard UI

Create a Dashboard user

This example demonstrates how to create a user account with administrative rights. If you need to create a new user, assign permissions, and generate an individual token for that user, refer to the creating a sample user.

1. Create a manifest file (e.g., dashboard-adminuser.yaml) and add the following snippets to it:
   1. Creating ServiceAccount with the name admin-user in namespace kubernetes-dashboard:

      apiVersion: v1
      kind: ServiceAccount
      metadata:
      	name: admin-user
      	namespace: kubernetes-dashboard
      

   2. Creating a ClusterRoleBinding for the ServiceAccount

      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
      

2. Save the file and apply it using the following command:

   kubectl apply -f {path to the dashboard-adminuser.yaml file}

The user account has now been successfully created.

Command line proxy

You can enable access to the Dashboard using the kubectl command-line tool, by executing the following command:

kubectl -n kubernetes-dashboard port-forward svc/kubernetes-dashboard-kong-proxy 8443:443

Kubectl will make Dashboard available at https://localhost:8443.

In the Bearer Token field, enter the value obtained from the customer portal → Kubernetes Cluster Details → Secret field.

The UI can only be accessed from the machine where the command is executed. Use the kubectl port-forward --help command for more options.
