+# ============================================================
+# Gitea Actions CI/CD — 自动迁移 → 构建 → 部署到 Runner 本机
+#
+# 前置条件：
+#   1. Gitea Runner (act_runner) 已注册，Runner 有 Docker 权限
+#   2. Runner 服务器已执行首次初始化（仅一次）：
+#      docker network create yudao-net
+#      docker compose -f script/docker/docker-compose.yml up -d postgres redis
+#   3. Runner Docker 需配 registry-mirrors（国内加速拉镜像）
+#
+# 数据库连接：
+#   CI 容器通过宿主机 IP 连接持久化 PostgreSQL（非临时 service）
+#   默认使用 172.17.0.1（Docker 默认网桥）；如果不对，设置 runner 环境变量 DOCKER_HOST_IP
+# ============================================================
