# ============================================
# Switchboard Core - Backend Deployment
# ============================================
# Secrets:
#   switchboard-db-credentials  - POSTGRES_USER, POSTGRES_PASSWORD
#   switchboard-admin           - username, password, email (optional)
#   switchboard-encryption      - ENCRYPTION_KEY (required for v0.9.4+)
#
# PVC:
#   switchboard-storage         - Extraction scratch (always needed)
#   Requires ReadWriteMany (RWX) — see k8s/storage-pvc.yaml
#   With S3 backend, PVC is small (extraction status only, not blobs)
#
# Variables (Gitea CI):
#   STORAGE_CLASS               - StorageClass for PVC (e.g. "cephfs")
#   STORAGE_SIZE                - PVC size (e.g. "10Gi" for PVC, "1Gi" for S3)
#   STORAGE_BACKEND             - "pvc" or "s3" (default: "pvc")
#   EXTRACTION_CONCURRENCY      - Max concurrent extractions (default "3")
#   EXTRACTOR_IMAGE             - Sidecar image (LibreOffice headless)
#
# S3 secrets (Gitea Secrets — only when STORAGE_BACKEND=s3):
#   S3_ENDPOINT                 - e.g. "http://minio:9000" or Ceph RGW URL
#   S3_BUCKET                   - bucket name (must exist before deploy)
#   S3_ACCESS_KEY               - S3 access key
#   S3_SECRET_KEY               - S3 secret key
#
# Admin bootstrap: on every pod start, if SWITCHBOARD_ADMIN_* env vars
# are set, the backend upserts an admin user. Change the secret and
# restart the pod to reset the admin password.
