# syntax=docker/dockerfile:1
# =============================================================================
# book-feeder — Project Gutenberg + Open Library feeder sidecar. Multi-stage
# build; build context is this repo's root (the Cargo workspace).
#
# meta-feeder-sdk arrives as a git dependency (tag-pinned), so the vendored
# `crates/` copy is not copied in — `git` must be present in the builder for
# cargo to fetch it. Same BuildKit cache-mount strategy as the gateway
# Dockerfile: the cargo registry/git and `target/` persist across builds. The
# release binary is copied OUT of the target cache mount within the same RUN.
