# Grafana cluster deployment Argo CD owns the Grafana Helm release and the dashboard ConfigMaps in `resources/`. The selected upstream chart version is recorded once in `bootstrap/grafana.yaml`; change it there to upgrade. The existing `grafana` Secret supplies the admin credentials, while `grafana-postgres-secret` supplies database and OAuth credentials. They are referenced by name and must remain cluster-managed; do not add their data to this public repository. The prior Helm release record is retained for recovery and must not be upgraded or uninstalled after Argo adoption.
