Question

我正在从事.Net核心项目。有八个并行运行的容器。下面是屏幕截图。

显示所有容器

每当我运行make start时，所有容器都会开始运行，并且我也可以运行UI和API。如果我想在UI或API中进行更改，那么我将在代码中进行更改并重新启动容器。我想调试邮递员的API。每当我尝试调试vs代码中的api代码，但在代码中尝试与容器中运行的其他服务进行通信时，就会出现异常。就我而言，与Postgres DB建立连接时出现错误。下面是我的docker.compose.yml

我可以知道在本地调试API的方法是什么？如果有人通过可用的调试方法帮助我，那将非常有帮助。任何帮助，将不胜感激。谢谢

如何在容器中调试.net核心？
