Docker sandbox 环境变量治理：用 env_file 替代散落明文 env
问题/场景：在沙箱任务里直接写多行环境变量，容易出现泄漏与配置漂移。前置：使用 Docker sandbox，并可维护受控 env 文件。实施步骤：集中维护 env_file、引用到 sandbox 配置、重启后做最小冒烟验证。关键命令：`openclaw gateway restart`、`openclaw status`。验证：任务容器能读取所需变量且日志不暴露敏感值。风险：env 文件权限和路径挂载错误会导致任务启动失败。来源：GitHub PR。

Prerequisites
- OpenClaw deployment uses Docker sandbox execution mode.
- You can create and permission-control an env file readable by gateway runtime.
Steps
- Create a dedicated env file (for example .sandbox.env) and move sensitive vars out of inline config.
- Reference this file in Docker sandbox config via env_file field.
- Restrict file permissions to runtime user and restart gateway to apply config.
- Run one sandbox task that requires these vars and inspect logs for redaction/no secret echo.
Commands
chmod 600 .sandbox.envopenclaw gateway restartopenclaw statusVerify
Sandbox task starts successfully with required env vars and no plaintext secrets appear in logs.
Caveats
- Never commit env files with secrets to git; keep them in secure local/secret storage.
- env_file schema path may change before final release tag; verify against your installed version（需验证）.
