下面是来自https://blog.jetbrains.com/pycharm/2017/03/docker-compose-getting-flask-up-and-running/的非常有用的教程
以示例应用为例，运行docker-compose up，一切正常，URL运行为http://0.0.0.0:5000
但是，在按照PyCharm的设置将项目解释器设置为docker-compose之后，我可以运行，但是无法连接到服务器（连接已重置）。
尝试通过Docker（而不是Docker Compose）配置运行应用程序时，得到相同的结果。
PyCharm中是否需要指定端口转发的区域？
docker-compose up --build的结果：
