This will create a public issue which anybody can view and comment on.

Please provide as much information as possible. At least, this should include a description of your issue and steps to reproduce the problem. If possible please provide a summary of what steps or workarounds you have already tried, and any docs or articles you found (un)helpful.

Problem you have encountered:
When the customer used the documentation [1] to create Config Controller Cluster, the documentation mentioned that Because Config Controller is a managed service, Google upgrades it automatically.

What you expected to happen:
As any cluster is there a way to have a notification for the next update event so the cx can prepare the workload, as the upgrade causes a whole environment to be down.

Or if there is a way to set GKE maintenance windows and exclusions.

Steps to reproduce:
Follow the documentation [1] https://cloud.google.com/anthos-config-management/docs/how-to/config-controller-setup#before_you_begin
