# By default the app's data and the database live in named Docker volumes
# (app_files, app_thumbs, app_import, db_data). To keep them in specific folders
# on the host instead, point any of these at a host path — absolute, or relative
# to this file (e.g. ./data/files). Unset = named volume.

# DB_DIR=/var/lib/tanabata/db

# When bind-mounting the app folders above, the container must be able to write
# to them. Set PUID/PGID to the owner of those folders and create them with
# matching ownership first, e.g.:
#   sudo mkdir -p /var/lib/tanabata/{files,thumbs,import}
#   sudo chown -R 1000:1000 /var/lib/tanabata
#   PUID=1000
#   PGID=1000
# Defaults match the image's tanabata user (42776), which owns the named volumes. The
# DB folder is handled by Postgres itself and needs no PUID/PGID.
