#
# integration-fixtures.sh — throwaway, self-contained fixtures for the v2-integration workflow (#757).
#
#   up    start SQL Server, PostgreSQL (seeded), QuestDB, opc-plc and a port-NAT opc-plc as containers named
#         otopcua-ci-*, wait until each is usable, and print the env exports the
#         *.IntegrationTests fixtures read (also appended to $GITHUB_ENV when set).
#   down  remove those containers (idempotent; touches nothing else).
#
# Deliberately NOT the shared 10.100.0.35 host: CI must not depend on that box, and these
# containers are created and destroyed inside the job. Host ports are non-default so a
# developer's own fixtures are never clobbered when the script is run locally.
#
# Reaching the containers: on the host (or a host-network job) that is 127.0.0.1; when the job
# itself runs inside a container (/.dockerenv) the published ports live on the docker host,
# i.e. the container's default gateway. Override with FIXTURE_HOST.
