# Domain: paperless.${DOMAIN}
# Database: PostgreSQL + Redis
# RAM: ~500MB (more with OCR/Tika) | Pi-compatible: Yes (arm64, 4GB+ RAM recommended)
#
# Environment variables (set in Portainer):
#   DOMAIN                  - Your domain (e.g., demo-felhom.eu)
#   HDD_PATH                - HDD mount path (e.g., /mnt/hdd_1)
#   PAPERLESS_SECRET_KEY    - Random secret (generate with: openssl rand -hex 32)

#   PAPERLESS_ADMIN_USER    - Initial admin username (default: admin)
#   PAPERLESS_ADMIN_PASSWORD - Initial admin password
#
# Storage layout:
#   Consume folder   → ${HDD_PATH}/storage/paperless/consume   (HDD, drop files here)
#   Document media   → ${HDD_PATH}/storage/paperless/media      (HDD, originals + archive)
#   Export folder    → ${HDD_PATH}/storage/paperless/export     (HDD, for backups)
#   App data/index   → paperless_data                            (named volume, NVMe)
#   PostgreSQL data  → paperless_postgres_data                   (named volume, NVMe)
#   Redis data       → paperless_redis_data                      (named volume, NVMe)
#
# First-time setup:
#   If PAPERLESS_ADMIN_USER/PASSWORD env vars are set, admin is auto-created.
#   Otherwise: docker exec -it paperless-webserver createsuperuser
