# shopdb-flask single-site container.
#
# One image, one site. Per ADR-004, each adopting facility runs its own
# stack with its own DB, secrets, and enabled-plugin list. This image
# bundles all six core plugins; install them at runtime with
# `flask plugin install <name>`.
#
# Build:
#   docker build -t shopdb-flask .
# Run (with .env):
#   docker run --env-file .env -p 5001:5001 shopdb-flask
