# PostgreSQL for the MasterOne portal (hostPath PV — single-node local cluster;
# data persists on the host under /root/rancher/data/masterone/postgres).
# NOTE: Longhorn migration pending — Longhorn volumes fail to attach on this
# nested-docker node (iscsid lifetime issue). hostPath is the working config.
