# CRDs only, extracted to plain YAML (`helm show crds kube-prometheus-stack`)
# and committed to git under k8s/infra/monitoring/crds/, applied via Server-
# Side Apply to avoid the etcd 262144-byte last-applied-configuration
# annotation limit that client-side apply hits on these very large CRDs
# (prometheuses, alertmanagers, scrapeconfigs, etc). A plain git path source
# (not a remote Helm source) is used deliberately so ArgoCD applies exactly
# these 8 CRD manifests and nothing else — no ambiguity about what "CRDs only"
# means from a Helm chart. Split out from the main `prometheus` Application
# (helm.skipCrds: true there) because ServerSideApply conflicts with that
# app's managedNamespaceMetadata.
# NOTE: bump k8s/infra/monitoring/crds/kube-prometheus-stack-crds.yaml
# whenever the kube-prometheus-stack chart version changes materially
# (`helm show crds prometheus-community/kube-prometheus-stack > ...`).
