Hi, Im using version: hashicorp/azurerm v2.79.0
And we still get:
"Feature Microsoft.ContainerService/AutoUpgradePreview is not enabled. Please see https://aka.ms/aks/previews for how to enable features."

When this parameter is not specified. Default value seems not to be None.

Experiencing the same issue as of 2.79.0 when building AKS cluster.

"Feature Microsoft.ContainerService/AutoUpgradePreview is not enabled. Please see https://aka.ms/aks/previews for how to enable features."

I'd expect that defaulting to none should also allow you to explicitly set automatic_channel_upgrade = none. However, I get the following on terraform plan:

Error: expected automatic_channel_upgrade to be one of [patch rapid stable node-image], got none

[tombuildsstuff]

@fcatacut you can specify none by omitting the field / setting this value to null

@fcatacut you can specify none by omitting the field / setting this value to null

Original Error: Code="BadRequest" Message="Feature Microsoft.ContainerService/AutoUpgradePreview is not enabled.

I set automatic_channel_upgrade to null, but still have the same error

[Sanverik]

The same situation when I am just omitting the field automatic_channel_upgrade

Tryning to speak for aks. Think we've created some confusing here. @favoretti @tombuildsstuff None not actaully the default blank or unspecified is. This is because we're reserveing the right to change the default in the future but still let the customer opt out to none.

Azure/AKS#2584

this does not work in 2.80 when automatic_channel_upgrade is set to null or "none" or "".

meaning I cannot create kubernetes cluster with the azurerm provider >= 2.79.

@tombuildsstuff posted a message in the corresponding AKS issue: Azure/AKS#2584 (comment). For now, I'd suggest just pinning to 2.78. Hopefully, you don't need any new functionality or bug fixes that are available in a later version.
