# Test infrastructure for redis-rb. Topology selection via Docker profiles:
#   docker compose --profile standalone up -d --wait   (just the master)
#   docker compose --profile replica    up -d --wait   (master + replica, no sentinels)
#   docker compose --profile sentinel   up -d --wait   (master + replica + 3 sentinels)
#   docker compose --profile cluster    up -d --wait   (6-node cluster)
#   docker compose --profile modules    up -d --wait   (Redis Stack instance for module tests)
#   docker compose --profile all        up -d --wait   (everything)
#
# Override the Redis version with REDIS_VERSION=8.X.Y. The image is amd64-only,
# so on Apple Silicon the platform is pinned via Rosetta emulation.
#
# Uses host networking so the test runner reaches services via 127.0.0.1 at the
# ports redis-rb has used historically: 6381 / 6382 / 6383 / 6400-6402 / 16380-16385.
# This is the simplest model that keeps sentinel and cluster reporting host-
# reachable addresses.
#
# macOS note: Docker Desktop requires the "host networking" beta feature
# (Settings > Resources > Network > Enable host networking). Without it, Linux
# containers can use host networking inside the VM but their ports won't be
# visible on the macOS host. CI runs on Linux and is unaffected.
