# A GoCommerce store on your own machine, in one command.

#   curl -O https://kitcommerce.store/docker-compose.yml
#   curl -o .env https://kitcommerce.store/env.example
#   docker compose up -d
#
# What this starts, and what it deliberately does not:
#
#   postgres    the database GoCommerce owns
#   gocommerce  the commerce API *and* the Svelte admin — one Go binary, because
#               the admin is compiled into it with //go:embed. There is no
#               separate admin service to run, and adding one would be theatre.
#   web         Caddy in front, so the store answers on port 80 rather than 8080
#               and there is one place to add TLS later.
#
# Svelte Commerce is behind a profile, not in the default set. It starts with
#
#   docker compose --profile storefront up -d
#
# and serves on port 3000 — but it does not read from this stack as it stands.
# The GoCommerce connector for Svelte Commerce, @misiki/gocommerce-connector,
# is published but early (0.1.0), and it is not in this image: Svelte Commerce
# ships with its Litekart and Vendure connectors. To pair them, install the
# GoCommerce connector in a Svelte Commerce checkout in their place and point it
# at this stack with PUBLIC_GOCOMMERCE_API_URL=http://gocommerce:8080. It
# covers catalogue, cart, checkout and order lookup, not customer accounts or
# search, and no store is known to run the pair in production. The service is
# here so its definition exists, not because the pair works from this file.
# See https://kitcommerce.store/gocommerce-svelte-commerce-connector/
#
# GoCommerce builds from source rather than pulling a published image, because
# no image is published yet. The first run compiles Go and takes a few minutes;
# later runs are cached.
