How to add private nuget source in dotnet dockerfile?

问题

I try to add (override) a private nuget source to my build script in order to add the user/pw - and keep it out of my source control. What I tried so far:

nuget is not recognized as command inside the image
dotnet nuget does not have the command to add additional sources
installing nuget does not effect dotnet restore

FROM mcr.microsoft.com/dotnet/core/sdk:2.2 
RUN apt-get update && apt-get install -y nuget 
RUN nuget source Add -Name "Private Feed" -Source ".." -UserName "UserVAR" -Password "PassVAR"
RUN dotnet restore

By adding a nuget.config to the solution/project and copying it into the Docker project:

WORKDIR /src
COPY ["nuget.config", ""]

You can add the source and then have success with your docker build.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    <add key="Nellson Nuget Repo" value="http://private.source.local:123/v3/index.json" />
  </packageSources>
  <activePackageSource>
    <add key="NuGet official package source" value="https://api.nuget.org/v3/index.json" />
    <add key="Nellson Nuget Repo" value="http://private.source.local:123/v3/index.json" />
  </activePackageSource>
</configuration>

My current workaround is to create a copy of the nuget.config with a packageSourceCredentials section that contains placeholders for user name and password. I then replace my existing nuget.config with this file and replace the user name and password with environment variables.

The only drawback is that I need to keep both config files in sync. If I modify my nuget.config in the project I need to remember to update the copy as well.

nuget.config.template

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="GitHub private registry" value="https://nuget.pkg.github.com/your_orga/index.json" />
  </packageSources>
  <packageSourceCredentials>
    <GitHub_x0020_private_x0020_registry>
        <add key="Username" value="USER" />
        <add key="ClearTextPassword" value="PW" />
    </GitHub_x0020_nuget_x0020_registry>
</packageSourceCredentials>
</configuration>

Dockerfile

FROM mcr.microsoft.com/dotnet/core/sdk:2.2 AS build-image
ARG NUGET_AUTH_TOKEN
ARG NUGET_USER_NAME

WORKDIR /app
COPY ./My.Project .

# Replace nuget.config
RUN rm nuget.config
COPY ./gitlab-ci/nuget.config.template ./nuget.config
RUN sed -i -e "s/USER/$NUGET_USER_NAME/g" -e "s/PW/$NUGET_AUTH_TOKEN/g" nuget.config

RUN dotnet restore

.gitlab-ci.yml

docker build
      --build-arg NUGET_USER_NAME=$NUGET_USER_NAME
      --build-arg NUGET_AUTH_TOKEN=$NUGET_AUTH_TOKEN
      --tag $CI_REGISTRY/organization/application:$CI_COMMIT_SHA
      --file gitlab-ci/Dockerfile
      .

The nuget source command is part of the nuget.exe command line interface, which can only be used on Linux in combination with Mono. Because the mcr.microsoft.com/dotnet/core/sdk image is a Linux container (Debian, to be precise) - you will need to install Mono and Nuget yourself in order to use that command. Your other option is to get the official Mono docker image and install .NET Core and NuGet.exe into that.
