# syntax=docker/dockerfile:1.7
#
# Local-dev image for the gateway service. Mirrors `gateway/Dockerfile`
# (the integration/production image) but switches the runtime stage to
# alpine so docker-compose healthchecks can shell out to `wget`.
#
# Build via the local-dev compose: `make -C tools/local-dev up`. The
# build context is the repository root.
