Getting Started with ApplicationSets - Red Hat The main implication here is that it takes If we have autoprune enabled then ArgoCD would try to delete this object immediately which would be pretty bad for us because we want to get our new app built and the deletion cancels this all of a sudden. in a given Deployment, the following yaml can be provided to Argo CD: Note that by the Deployment schema specification, this isn't a valid manifest. The sync was performed (with pruning disabled), and there are resources which need to be deleted. The patch is calculated using a 3-way-merge between the live state the desired state and the last-applied-configuration annotation. Argo CD cannot find the CRD in the sync and will fail with the error the server could not find the requested resource.
