# Local-dev image for the backend service. Mirrors the structure of
# `backend/Dockerfile` (the integration/production image) but switches
# the runtime stage to alpine so docker-compose healthchecks can shell
# out to `wget` and the container can run as root for Docker-socket
# access without needing the production-grade nonroot guarantees.
#
# Build via the local-dev compose: `make -C tools/local-dev up`. The
# build context is the repository root.

# Bake the GeoIP test database into the build context so downstream

# `MaxMind-DB` git submodule under `pkg/geoip/test-data/`; the file is
# the smallest country DB MaxMind publishes and is what every other
# dev-stack uses. Baking it lets dev-deploy skip the bind-mount that
# fails on runner-workspace volumes the host Docker daemon cannot see.
