# wallet-monitor/Dockerfile — image for the one-shot wallet-balance alerter.
#
# Same multi-stage tsx strategy as supplier/Dockerfile: install workspace deps
# in a builder stage, ship source + node_modules to a slim runtime stage, run
# the entry point with tsx (we do NOT compile ahead-of-time because
# @marketplace/shared exports .ts via package.json#exports — see supplier/Dockerfile).
#
# This is NOT a long-running server: there is no HEALTHCHECK / EXPOSE. It's
# invoked one-shot by cron: `docker compose -f deploy/mainnet/docker-compose.wallet-monitor.yml run --rm wallet-monitor`.
#
# Build context MUST be the repo root so pnpm can resolve workspace deps:
#   docker build -f wallet-monitor/Dockerfile -t marketplace-wallet-monitor .
