docker-compose.contract.yml

# Self-contained brokers for the broker contract suite (EVO-1199).
#
# Unlike docker/docker-compose.{kafka,rabbitmq}.yml (which require the external
# `local-net` network and ship dev-only extras like kafka-ui), this compose is
# standalone: a plain bridge network + healthchecks so CI and the local suite
# can `up -d`, wait for healthy, and run without touching the dev stack.
#
#   docker compose -f docker-compose.contract.yml up -d
#   BROKER_CONTRACT=1 \
#     KAFKA_BROKERS=localhost:9092 \
#     RABBITMQ_URL=amqp://admin:admin@localhost:5672 \
#     npm test -- broker.contract.spec
