Question

我必须在Centos7的docker中运行flask应用程序。现在我遇到了一些问题，但是无论在本地还是在AWS上，我都只能在docker中运行flask应用程序。那么在哪里可以找到记录器信息？

有我的config.py：

import os
base_path = "/opt/cv_parser_data"

port = os.getenv('PORT', 3000)

store_dir_prefix = "%s/cv_store/" % base_path

log_path = "%s/log/" % base_path

tmp_file_path = "%s/tmp_file/" % base_path

使用此命令：

admins-MacBook-Pro:~ admin$ sudo npm i -g @angular/cli@latest npm ERR! path /usr/local/bin/ng npm ERR! code EEXIST npm ERR! Refusing to delete /usr/local/bin/ng: ../lib/node_modules/angular-cli/bin/ng symlink target is not controlled by npm /usr/local/bin npm ERR! File exists: /usr/local/bin/ng npm ERR!

希望获得帮助！

如果没有docker，您的日志没有打印到stdout，那么有了docker，它们也不会被打印到stdout，那么您就无法使用docker logs看到它。

如果是上述情况，则必须进入容器以查看日志，请参见this。

对于您的情况，您提到了log_path = "%s/log/" % base_path，很多人都输入了next，然后cd进入上方的文件夹以查看日志。

docker exec -it $your_container_name /bin/bash
