# syntax=docker/dockerfile:1.7
#
# gateway/Dockerfile — multi-stage image for the OpenAI-compatible gateway.
#
# Mirrors buyer/Dockerfile: we do NOT run `tsc` for the server because
# @marketplace/shared and @marketplace/buyer export .ts directly via
# package.json#exports — the tsx loader handles them at runtime. The gateway
# reuses the buyer's Marketplace SDK + lucid (buildAcceptTx / buildWithdrawTx),
# so it needs the same better-sqlite3 native rebuild + libsodium patch and the
# contracts/marketplace/plutus.json blueprint.
#
# Build:
#   docker build -f gateway/Dockerfile -t marketplace-gateway .
