Suspend sync globally in ArgoCD?

Question

Is there a way in Argo CD to suspend sync globally? For example, my company occasionally does deployment freezes in which no one is allowed to ship to production. Is there a way to turn off sync globally in Argo CD to prevent new versions of apps from deploying?

Answer 1

As LostJon commented, you can scale the application controller down. But then you won't see the current state of resources in the UI - only the state as of the moment the controller was shut down.

Instead of scaling down the controller, you can set a sync window on a global project.
