Master Node on AKS cluster
Is it possible to look at Master node? The reason I want to do this is to check if RBAC is enabled in my cluster, and if not, enable it.
It is not possible, Kubernetes master node managed by Azure, because Azure handles these critical maintenance tasks for you, AKS does not provide direct access (such as with SSH) to the cluster.
If you need more control over the Azure resource manager templates, you can use the open source acs-engine project to build your own custom kubernetes cluster and deploy it via the az CLI.
Use the below command using azure CLI to verify if the clsuter has RBAC enabled or not
az resource show -g <resource-group-name> -n <aks-cluster-name> --resource-type Microsoft.ContainerService/ManagedClusters --query properties.enableRBAC
