aks_nodepools_without_autoscaling

AKS Node Pools Without Autoscaling

What It Does

This policy will raise an incident if there are any AKS clusters with user node pools that do not have autoscaling enabled.

How It Works

This policy checks all the user node pools associated with each AKS cluster. If the 'enableAutoScaling' value for a node pool is set to 'false', that node pool is added to the list of problematic pools, and an incident is raised if this list contains any items.
