Now that youve installed and set up the Kubernetes dashboard, the only thing left to do is enjoy its functionality! We will be creating a Kubernetes cluster using Azure Kubernetes Service (AKS), you will need an Azure account, the Azure CLI, Kubectl and Helm. The UI can only be accessed from the machine where the command is executed. For demonstration purposes, we will now create a ClusterRoleBinding and assign the ClusterRole cluster-admin to the ServiceAccount. Import the certificates to your Azure Stack Hub management machine. You will need to stop the previous port forward command, or run this in another terminal if you would like to run them side by side. On Azure Kubernetes Service (AKS) clusters with AAD enabled, you need oauth2-proxy to login the AAD user and send the bearer token to the dashboard. To verify that the Kubernetes service is running in your environment, run the following command: 1. Next, delete the Kubernetes dashboard pod using the name found in step three using the kubectl delete command. For supported Kubernetes clusters on Azure Stack, use the AKS engine. Prometheus and Grafana make our experience better. This article shows you how to set up the Kubernetes dashboard on Azure Stack Hub. For more information on the Kubernetes dashboard, see Kubernetes Web UI Dashboard. Update the script with the locations, and then open PowerShell with an elevated prompt.
