# Sipher federation test cluster
#
# Three independent Sipher instances (A, B, C) sharing one Postgres server
# (separate databases) and one Redis server (separate logical DBs 0/1/2).
#
# All commands below should be run from the repository root with the explicit
# compose file (-f tests/docker-compose.yml) — `package.json` already wraps
# the common ones (docker:generate-keys, docker:build, docker:setup-discovery).
#
# Quick start
# ───────────
#   1.  bun run docker:generate-keys                       # writes tests/docker/sipher-{a,b,c}.env
#   2.  docker compose -f tests/docker-compose.yml \
#         --profile init up                                # push DB schema (exits when done)
#   3.  docker compose -f tests/docker-compose.yml up -d   # start the cluster
#   4.  docker compose -f tests/docker-compose.yml \
#         --profile setup up                               # mutual discovery (exits when done)
#
# Running integration tests
# ─────────────────────────
#   docker compose -f tests/docker-compose.yml run --rm test-runner \
#     tests/integration/proxy-chain.ts \
#     --proxy http://sipher-b:3001 --target http://sipher-c:3002
#
#   docker compose -f tests/docker-compose.yml run --rm test-runner \
#     tests/integration/federation-post-delivery.ts \
#     --proxy http://sipher-b:3001 --target http://sipher-c:3002
#
# Both integration scripts now auto-create their own Better Auth users + identity
# keys + follow rows via HTTP, so you no longer need to pass --bearer.
#
# Teardown
# ────────
#   docker compose -f tests/docker-compose.yml down       # stop (keeps volumes)
#   docker compose -f tests/docker-compose.yml down -v    # stop + wipe all data volumes
# ─────────────────────────────────────────────────────────────────────────────

# Pinned project name so the docker objects (containers, network, volumes) keep
# stable names regardless of the directory containing this compose file. Docker
# would otherwise default to the parent directory of the compose file.

  # ── Sipher instances ─────────────────────────────────────────────────────────
  # Each instance:
  #   • has its own Postgres database (sipher_a / _b / _c)
  #   • has its own Redis logical DB (0 / 1 / 2) — isolates BullMQ queues and
  #     rate-limit buckets so instances don't interfere with each other
  #   • has a unique federation Ed25519 + X25519 keypair (generated by docker:generate-keys)
  #   • lists sipher-a/b/c in DEV_ALLOWED_HOSTNAMES so the SSRF url-guard allows
  #     outbound federation requests to the other instances over the Docker network
