Dotnet restore fails to use the local Nuget.Config to retrieve nuget packages from private feeds while building docker image

Steps to reproduce

add a Nuget.Config to your project with a private feed and run dotnet restore as part of docker build. Below is the basic Docker file that I am using.

FROM microsoft/dotnet:latest
COPY . /app
WORKDIR /app
RUN ["dotnet", "restore"]
RUN ["dotnet", "build"]
EXPOSE 80
CMD ["dotnet", "run", "--server.urls", "http://*:80"]

Dotnet restore fails because it is not using the package sources from the nuget.config file inside the project. Below is the Nuget.Config file that I am using (mocking the private feed name).

<?xml version="1.0" encoding="utf-8"?>
<configuration>
 <packageSources>
    <clear/>
    <add key="private package source" value="http://artifactory.private.svc/artifactory/api/nuget/nuget-release-local" />
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" />
  </packageSources>
</configuration>

Expected behavior

NuGet Config files used: /root/appName/Nuget.Config /root/.nuget/NuGet/NuGet.Config

Feeds used: http://artifactory.private.svc/artifactory/api/nuget/nuget-release-local https://api.nuget.org/v3/index.json

Actual behavior

NuGet Config files used: /root/.nuget/NuGet/NuGet.Config

Feeds used: https://api.nuget.org/v3/index.json

I had the same problem and I did something similar,

COPY NuGet.Config /root/.nuget/NuGet/

I had the same issue but my file was capitalized “Nuget.confg” originally and changing it to “NuGet.Config” appears to have worked.
