# key holds shell `export MINIO_ROOT_USER=...` lines. Created out-of-band
# (SOPS), see minio-secrets.enc.yaml. NOTE: the operator health-monitor logs a
# cosmetic "empty tenant credentials" warning (it greps for legacy
# access_key/secret_key keys) — MinIO itself authenticates fine; ignore it.

# Per the 3-CP topology only talos-cp-1 is schedulable and holds Longhorn, so
# MinIO is a single-server tenant. 4 volumes give erasure-coded durability
# (MinIO's minimum for parity) on that one node.
