Kubernetes defaults apiVersion=v1 and kind=PersistentVolumeClaim onto every
StatefulSet volumeClaimTemplates entry, but neither the raw manifests nor the
rendered helm charts emit those fields. Live StatefulSets therefore carry
TypeMeta that git lacks, and ArgoCD reports a diff removing it. Because
volumeClaimTemplates are immutable on an existing StatefulSet, ArgoCD can never
apply the removal, so consul-server, kanidm and nats stay perpetually OutOfSync
and can contribute to sync failures.
Add a fleet-wide resource.customizations.ignoreDifferences for apps/StatefulSet
that ignores the defaulted apiVersion/kind under every volumeClaimTemplates
entry. A single global customization covers the affected StatefulSets across
both raw manifests (kanidm) and helm renders (consul, nats), and is inert for
those whose charts already emit TypeMeta (vault, woodpecker).
