我有。net核心解决方案包含一些微服务项目，当我试图在dokcer上发布我的项目时，我得到一些错误

当我输入地址
时https://api.nuget.org/v3-flatcontainer/system.io.filesystem/4.0.1/system.io.filesystem.4.0.1.nupkg在浏览器中，包被下载，但是Docker不能从同一个地址下载
我的操作系统是windows 10，我在上面使用docker桌面来构建镜像，
我用Visual Studio和Docker命令(Docker -compose up)两种方式创建了图像我遇到了同样的问题在这两个方法
可能是SSL的问题因为另一个错误消息是:
Retrying 'FindPackagesByIdAsync' for source 'https://api.nuget.org/v3-flatcontainer/microsoft.extensions.hosting.abstractions/index.json'.
The SSL connection could not be established, see inner exception.
Received an unexpected EOF or 0 bytes from the transport stream.
如何解决
我也有同样的问题，原因是我的网速慢。在dotnet恢复命令中必须使用--disable-parallel标志像

这个标志的缺点是你的docker构建时间上升了很多
