Is it possible to remove the network policy setting from an AKS cluster?

Question

I have a pre-existing AKS cluster that I am looking to test Karpenter on. A pre-requisite for that is the Azure CNI Overlay. The console and documentation says Overlay is not possible with network policy being set. Is there a way to change from network policy azure to no network policy without recreating the AKS cluster?

Thanks for posting your question in the Microsoft Q&A forum.

You can change the network policy to "none" using the Azure CLI command:

az aks update --resource-group YOUR_RESOURCE_GROUP --name YOUR_CLUSTER_NAME --network-policy none

This command will disable the current network policy on your AKS cluster. However, there are a few important considerations:

• Your AKS cluster must be running version 1.22 or later
• The cluster should not have any Windows node pools
• Ensure that you have removed any existing network policies from your cluster before running this command.
