用法:
./scripts/deploy/production-api-deploy.sh --source-dir build/<version> [--version <version>] [--release-root /opt/genarrative/releases] [--current-link /opt/genarrative/current] [--service genarrative-api.service] [--health-url http://127.0.0.1:8082/readyz] [--api-env-file /etc/genarrative/api-server.env] [--database genarrative-prod] [--spacetime-server-url http://127.0.0.1:3101]
说明:
进入维护模式,校验并发布 api-server 单文件,更新 current 链接,重启 systemd 服务并执行 readiness 检查。
若传入 --database,会在重启前把 GENARRATIVE_SPACETIME_DATABASE 写入 api-server 环境文件,避免服务继续读取旧库。
失败时保留维护模式。
