# All-in-one image: PocketBase + API Server + Web App in a single container.
#
# The build context MUST be the project root so this file can reach both
# "API Server/" and "Web App/". The root .dockerignore is an allow-list of the
# paths copied below — add to it if you add a COPY here. Build it with:
#
#   docker build -f "Docker-AIO/Dockerfile" -t drivervault-aio .
#
# Run it (all three services start together):
#
#   docker run -d --name drivervault -p 80:80 -p 8070:8070 \
#     -e PB_ADMIN_EMAIL=admin@example.com \
#     -e PB_ADMIN_PASSWORD=change-me \
#     -e DRIVERVAULT_SUPERADMIN_EMAIL=owner@example.com \
#     -e DRIVERVAULT_SUPERADMIN_PASSWORD=change-me \
#     -v drivervault_pb:/pb/pb_data \
#     drivervault-aio
#
# Then: web app on http://host/  and PocketBase admin on http://host:8070/_/
# On first boot the API Server creates the collections and the super-admin.

# leave it on: a release can add collections or fields the server needs, and a

# plugin settings, is created on demand; nothing else is.)
# For Anker Solix charger control, OCPP_REQUIRE_TLS (default true) rejects
# chargers that did not arrive over TLS — this image serves plain HTTP, so put a
# TLS-terminating proxy in front and set OCPP_PUBLIC_URL to the public wss://
# base, or set OCPP_REQUIRE_TLS=false on a trusted network.
# Pass them with `docker run -e ...`.

# pb_data holds everything that persists — the database, the uploads, and the
# server settings that used to sit in a file beside the binary. It is the only
# volume: the API Server keeps no state on disk. Both directories are
