Docker 化的 .net 8 应用未正确公开端口

问：

我正在尝试对dotnet 8 web api项目进行docker化。 我在安装了 Docker Desktop 的 Windows 10 上。

这是我正在使用的 Dockerfile

FROM mcr.microsoft.com/dotnet/aspnet:8.0 

WORKDIR /app

# Copy the built application from the build image
COPY ./bin/Release/net8.0/ /app

# Expose the port the app will run on
EXPOSE 5000

# Set the environment variable for ASP.NET Core
ENV ASPNETCORE_URLS=http://+:5000

# Set the entry point for the application
ENTRYPOINT ["dotnet", "Finch.Agents.dll"]

这是 launchSettings.json：

{
  "$schema": "https://json.schemastore.org/launchsettings.json",
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:60197",
      "sslPort": 44302
    }
  },
  "profiles": {
    "http": {
      "commandName": "Project",
      "dotnetRunMessages": true,
      "launchBrowser": true,
      "launchUrl": "swagger",
      "applicationUrl": "http://localhost:5000",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "https": {
      "commandName": "Project",
      "dotnetRunMessages": true,
      "launchBrowser": true,
      "launchUrl": "swagger",
      "applicationUrl": "https://localhost:7120;http://localhost:5000",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "launchUrl": "swagger",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}

这是我运行容器的docker-compose.yml部分

  finch-agent:
    image: finch-agent:1.0.0
    container_name: finch-agent
    ports:
      - "8081:5000"

以下是docker logs ...

---------------------------------------------
.... my logs ...
---------------------------------------------
warn: Microsoft.AspNetCore.Hosting.Diagnostics[15]

在字里行间出现了一些我打印的自定义日志消息，因此我确定应用程序正在运行。 此外，应用程序似乎正在正确侦听端口 80。-----

那么，如果我在 http://localhost:8081/swagger 打开浏览器时，为什么会出现 404 错误呢？（我在 http://localhost:8081/ 也遇到同样的错误）

PS：'也确定应用程序在运行时可以正常工作，而不是dockerized。dotnet run

编辑：

附加信息：在 pip3r 注释之后，我添加了以下信息：

结果netstat -anop

关于 Docker Desktop 的常规和安全设置，我可以添加其他公开 Web 应用程序的容器（不是 dotnet，例如。我有一个使用相同的docker-compsoe运行的phpmyadmin容器），工作正常。
