I have an AKS cluster with multiple user node pools. I have one node pool with 2 nodes. When I stop the node pool from the AKS portal using the Stop button, the 2 nodes don’t get scaled down. I still see them active when I call kubectl get nodes. Even in the portal it says Power state: Stopped (2/2 nodes ready).

I run into an issue when placing an AKS cluster behind a BASIC Azure Firewall.

I have an AKS in an Azure Subscription. AKS version is 1.26.x. Not old. And I have gone into Cluster Configuration and chose “Microsoft Entra ID authentication with Azure RBAC”. and not “Microsoft Entra ID authentication with Kubernetes RBAC”. It was initially set to Local account with Kubernetes.
