码头工人"Unable to bind to"

Question

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

我已经尝试了许多端口配置。我尝试导航到本地主机 ip 而不是本地主机。我也用谷歌搜索了一下，又用谷歌搜索了一下。

PS C:UsersjamiesourcereposAngularAngular> docker run -it -p 8080:80 angular

另外，这是我的码头工人文件

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，但我认为应用程序端口的问题，因为服务器运行在不同的位置，如您所见

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

所以试着绑定5000或5001

docker run -it -p 8080:5000 angular
or
docker run -it -p 8080:5001 angular

正如大卫提到的，你也需要倾听 尝试添加ENTRYPOINT [ "dotnet", "Angular.dll", "--urls", "http://0.0.0.0:5000"]如果没有，请按照评论中链接中的答案进行操作
