GitOps the Hard Way, with Argo CD

Creating the Destination Namespace Automatically

The CreateNamespace option tells Argo CD to create the destination namespace if it does not already exist.

By default, if the namespace in spec.destination.namespace is missing, the sync fails: Argo CD will not create it for you. Set CreateNamespace=true and Argo CD creates that namespace as part of the sync, before applying the rest of the resources.
