# Isolated MTConnect live-gate overlay (Task 21).
#
# Runs the MAIN central pair ONLY, from this worktree's image, under its own
# compose project + offset host ports, so the shared `otopcua-dev` rig and the
# three sibling driver worktrees that share `otopcua-host:dev` are untouched.
# Mirrors how the mqtt-sparkplug worktree isolated itself (`otopcua-host:mqtt`,
# project `otopcua-mqtt`, ports 9210/4850).
#
#   docker build -f docker-dev/Dockerfile --target runtime -t otopcua-host:mtconnect .
#   docker compose -p otopcua-mtc -f docker-dev/docker-compose.yml \
#                  -f docker-dev/docker-compose.mtconnect.yml \
#                  up -d sql migrator cluster-seed central-1 central-2
#
#   AdminUI  -> http://localhost:9220   (login disabled; auto-admin)
#   OPC UA   -> opc.tcp://localhost:4860 (central-1) / :4861 (central-2)
#   SQL      -> localhost,14340
#
# Both MAIN nodes run because `cluster-seed` declares MAIN as a 2-node cluster:
# ConfigPublishCoordinator sources its expected-ack set from enabled ClusterNode
# rows, so deploying with one node down fails at the apply deadline.
#
# Traefik is deliberately not started — central-1 publishes its AdminUI port
# directly, which removes the :9200 round-robin that otherwise makes it
# ambiguous which node served a request.

# NOTE: `!override` is required on every `ports` list. Compose MERGES list-valued
# keys by appending, so a plain re-declaration would keep the base file's
# "14330:1433" / "4840:4840" alongside the offsets and collide with the running
# `otopcua-dev` rig ("Bind for 0.0.0.0:14330 failed: port is already allocated").
