# visionA-backend docker-compose
#
# 對應：.autoflow/04-architecture/build-deploy.md §4
#
# 服務拓撲（Phase 0 雛形）：
#
#   browser ──(3721)──▶ api-server ──(internal:3801)──▶ remote-proxy
#                                                            ▲
#                                                            │
#                                           local agent ──(WS:3800)──┘
#
#  - api-server 無狀態；session state 全在 remote-proxy in-memory
#  - 兩個 service 用 compose 的 default bridge network（service 名稱互通）
#    因此 api-server 用 `http://remote-proxy:3801` 打 internal API
#
# 使用：
#   cd visionA-backend
#   cp .env.example .env          # 首次
#   docker compose -f docker/docker-compose.yml up -d
#   docker compose -f docker/docker-compose.yml logs -f
#   docker compose -f docker/docker-compose.yml down
