docker "Unable to bind to"

Question

我已经构建了我的第一个 .net core 3.0 docker 镜像，但是在尝试运行该镜像时，docker 返回了一些错误。

我尝试了许多端口配置。我尝试导航到 localhost ip 而不是 localhost。我也用谷歌搜索并搜索了更多。

PS C:\Users\jamie\source\repos\Angular\Angular> docker run -it -p 8080:80 angular
warn: Microsoft.AspNetCore.DataProtection.Repositories.FileSystemXmlRepository[60]
      Storing keys in a directory '/root/.aspnet/DataProtection-Keys' that may not be persisted outside of the container. Protected data will be unavailable when container is destroyed.

Hosting environment: Production
Content root path: /app
Now listening on: http://localhost:5000
Now listening on: https://localhost:5001
Application started. Press Ctrl+C to shut down.

另外，这是我的 dockerfile

FROM mcr.microsoft.com/dotnet/core/sdk:3.0
WORKDIR /app
COPY bin/Debug/netcoreapp3.0/publish .
ENTRYPOINT [ "dotnet", "Angular.dll"]

Answer 1

这些只是警告，但我认为来自应用程序端口的问题，因为服务器运行的不同，如您所见

Now listening on: http://localhost:5000
Now listening on: https://localhost:5001

所以尝试绑定(bind) 5000或 5001

docker run -it -p 8080:5000 angular

or

docker run -it -p 8080:5001 angular

正如大卫所说，你还需要倾听
尝试添加 ENTRYPOINT [ "dotnet", "Angular.dll", "--urls", "http://0.0.0.0:5000"]如果没有，请按照评论链接中的答案进行操作
