Python 使用flask、gunicorn、docker和azure处理请求时发生套接字错误

使用gunicorn运行python flask应用程序。当我在本地旋转docker映像时，一切都很好，但是当我在azure上使用kubernetes运行docker映像时，我得到了这个操作错误。请求正常，但日志中出现错误

有人知道发生了什么吗

使用启动应用程序

gunicorn --certfile Config/cert.crt --keyfile Config/cert.key -w 2 -b :8084 --access-logfile - gunicorn_app:app

将python版本从3.6.*升级到3.7.4，效果很好。

最后，我发现这是由pod liveness Probe造成的，因为gunicorn服务器目前无法同时支持http和https，如果我们只对公共域使用https，http Probe检查请求将失败，并出现此错误

解决方案：

将gunicorn服务器更改为Nginx或Apache。

我已将gunicorn更改为uwsgi，不再令人头痛

你能解决这个问题吗？我也犯了同样的错误。但是这里有更多的信息。在那里添加了一个问题，因为我在3.7.5上没有得到答案，仍然遇到这个错误。
