# Production image for @insignia/iios-service (the single IIOS backend).
# Build context MUST be the monorepo ROOT (it needs the workspace + lockfile):
#   docker build -f packages/iios-service/Dockerfile -t iios-service:latest .
#
# Multi-stage: (1) build the service + its workspace deps and prune to a
# self-contained prod bundle via `pnpm deploy`; (2) a slim runtime that only
# carries that bundle. Migrations run at container start (see docker-entrypoint.sh).
