Hello @alsikorski ,

thanks for proposing this new feature to the module. I have a question:

when setting automatic_channel_upgrade what happens to these other values ?

• kubernetes_version
• orchestrator_version

I mean setting kubernetes_version for example to 1.25.2 and automatic_channel_upgrade to patch. If the autoupgrade will upgrade the cluster to 1.25.3, will the next Terraform run complain for configuration drift ?
What is the best way to address this in the module ?

are you willing to propose a PR for this feature ?

thanks

Talked with @zioproto about the orchestrator_version. We haven't tested or validated this at all. Might need another PR?
