# Central backend in a container. Mirrors apps/machine-manager. Connects to an ALREADY-RUNNING MongoDB
# (start it from apps/mongodb: `docker compose up -d`).
#
# START IT WITH:
#   docker compose up -d --build
#
# Config: the local `.env` is injected straight into the container (env_file). Because that .env
# points at 127.0.0.1 for both MongoDB (:27017) and the agent-manager (publicHost :8090), the service
# uses HOST networking so those addresses resolve to the services on the same VM — no rewriting .env.
#
# Notes:
#   - `network_mode: host` is a Linux feature (this is the production path). On Docker-Desktop-Mac it's
#     unreliable → for Mac dev run the backend natively (`npm run dev`).
#   - With host networking `ports:` is ignored; the app binds PORT (default 8085, from .env) on the host.
#   - To use bridge networking instead: drop `network_mode`, add `ports: ["8085:8085"]` +
#     `extra_hosts: ["host.docker.internal:host-gateway"]`, and point DATABASE_URL (and the manager
#     publicHost it reads from the DB) at host.docker.internal.
