即使我没有使用 python 运行 os.walk 或任何其他类型的文件读/写操作，我也会收到此错误。

当我跑步时

find -L ./ -mindepth 15

我找到了循环中涉及的文件。本地是/usr/bin/X11和在服务器上我得到以下信息：

error walking file system: OSError [Errno 40] Too many levels of symbolic links: '/dev/fd/6/dev/fd/6/dev/fd/6/dev/fd/6/dev/fd/6/dev/fd/6/dev/fd/6/dev/fd/6/dev/fd/6/dev/fd/6/dev/fd/6/dev/fd/6/dev/fd/6/dev/stderr'

然后从 WatchGodReload：

Reloading...

要么我使用我通常绑定的卷运行容器：

UPLOADS_PATH=/var/opt/tmp
LOCAL_UPLOADS_PATH=/var/containers/TEST_UPLOADS

docker build --build-arg POSTGRES_USER --build-arg POSTGRES_PASSWORD --build-arg POSTGRES_SERVER --build-arg POSTGRES_DB --build-arg POSTGRES_PORT --build-arg UPLOADS_PATH --build-arg WHERE_AM_I --build-arg SESSION_SECRET --build-arg DO_YOU_WANT_USERS -t test .

docker run -d --name test_container -v ${LOCAL_UPLOADS_PATH}:${UPLOADS_PATH} -p 7000:7000 test

或者没有绑定，我仍然得到相同的错误日志，并且应用程序在每次请求后不断重启。

PS我也试过了docker system prune -a，虽然有过时的东西，但没有任何改变。

非常感谢任何关于进一步探索的建议。

这/dev/fd是一个特殊的伪设备文件系统，它显示VFS句柄或简单地说正在检查设备的 PID 的打开文件。通过容器中构建和运行进程的巧合，您的图像具有指向 /dev/fd 的链接，该链接与它试图读取的 /dev/fd 相同。

但是，如果您在伪设备上跟随符号链接链接，这并不罕见，因此当find -L您作为超级用户使用时，您应该排除/dev,/sys并且/proc在搜索和跟随链接时使用-xdev

采用

find -L ./ -xdev -mindepth 15

根据@jordanvrtanoski 的建议，我将关闭它，将其视为一个单独的问题。

他/她的回复也让我更好地理解了问题的性质，从而取得了进展。
