UnrecognizedArgumentError: unrecognized arguments: --auto-upgrade-channel stable

az feedback auto-generates most of the information requested below, as of CLI version 2.0.62

Describe the bug I am following this docs to enable auto-upgrade for AKS cluster https://docs.microsoft.com/en-us/azure/aks/upgrade-cluster#set-auto-upgrade-channel, but I am failed because of “UnrecognizedArgumentError: unrecognized arguments: --auto-upgrade-channel stable” error

To Reproduce Login in with az az account set --subscription SUBSCRIPTION_ID az feature register --namespace Microsoft.ContainerService -n AutoUpgradePreview --subscription SUBSCRIPTION_ID az provider register --namespace Microsoft.ContainerService --subscription SUBSCRIPTION_ID --wait az aks update --resource-group RESOURCE_GROUP --name AKS_NAME --auto-upgrade-channel stable --subscription SUBSCRIPTION_ID

Expected behavior Should have auto-upgrade enabled for the AKS

Hi all, I got the solution, try to run az extension add --name aks-preview before az aks update --name $AKS_CLUSTER_NAME --resource-group $RESOURCE_GROUP --auto-upgrade-channel stable @MateusAmin @g3gurung

@yonzhan Maybe the Microsoft should address this in the documentation.

a bit off topic, but can you add spot nodes after you enabled auto-upgrade?
