dotnet restore 在本地工作但在构建 Docker 容器时失败 [英] dotnet restore works locally but fails when building Docker container

问题描述

如果我使用 dotnet classlib -lang f# -o hello-docker 创建一个新的控制台应用程序，cd 进入目录，然后运行 ​​dotnet restore，一切都按预期进行.

If I create a new console application using dotnet classlib -lang f# -o hello-docker, cd into the directory and then run dotnet restore, everything works as expected.

但是，如果我添加具有以下内容的 Dockerfile

However, if I add a Dockerfile with the following content

FROM microsoft/dotnet:2-sdk

WORKDIR /hello

COPY hello-docker.fsproj .
COPY *.fs ./

RUN dotnet restore

RUN dotnet build

ENTRYPOINT [ "dotnet", "run" ]

并运行 docker build .，它无法访问 nuget.org 并显示以下消息:

and run docker build ., it fails to reach nuget.org with the following message:

/usr/share/dotnet/sdk/2.0.0/NuGet.targets(102,5): 错误:无法加载源的服务索引 https://api.nuget.org/v3/index.json.[/hello/hello-docker.fsproj]

命令/bin/sh -c dotnet restore"返回非零代码:1

The command '/bin/sh -c dotnet restore' returned a non-zero code: 1

为什么我可以在本地恢复，而不能在 Docker 容器内恢复?

Why can I restore locally, but not inside the Docker container?

推荐答案

我通过进入我的网络适配器上的属性/共享来修复它并与 hyper-v/docker 开关共享它......认为它被称为 nat 或东西.

I fixed it by going into properties/sharing on my network adapter and shared it with the hyper-v/docker switch...think it was called nat or something.
