+# DIDI PostgreSQL HA cluster — Patroni + etcd + HAProxy (IaC, reproducible)
+#
+# Containerized mirror of the production topology (see ../MIGRATION.md):
+#   prod: 3× PG/Patroni (10.11.50.160-162) + 3× etcd (163-165)
+#         + 2× HAProxy (166/169, VIP 167) + pgBackRest (168)
+#   here: 3× Spilo (Patroni+PG, Zalando) + 3× etcd + 1× HAProxy
+#         → same failover semantics, single-host footprint for
+#           demo/recepție/DR-rehearsal.
+#
+# Endpoints (identical contract to production):
+#   localhost:5000 → leader  (read-write)   [HAProxy checks Patroni /primary]
+#   localhost:5001 → replicas (read-only)   [HAProxy checks Patroni /replica]
+#   localhost:7000 → HAProxy stats UI
+#
+# Usage:
+#   docker compose up -d
+#   # wait ~30s for leader election, then:
+#   psql -h localhost -p 5000 -U postgres     # password: $PG_SUPERUSER_PASSWORD
+#   # restore DIDI schema:
+#   psql -h localhost -p 5000 -U postgres -f ../DIDI_full_export_2026-07-02.sql
+#   # failover drill:
+#   docker compose stop $(docker compose ps --format '{{.Name}}' | head -1)
+#   # → a replica is promoted in seconds; :5000 keeps serving writes.
