我试图在构建脚本中添加（覆盖）私有NuGet源，以便添加用户/密码并将其保留不在我的源代码控制之下。我到目前为止尝试过的：
nuget 在镜像内没有被识别为命令。dotnet nuget 没有添加其他源的命令。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
通过向解决方案/项目添加nuget.config文件并将其复制到Docker项目中：
WORKDIR /src
COPY ["nuget.config", ""]
您可以添加源代码，然后使用Docker构建成功。
<?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>
我的当前解决方案是创建一个包含用户名和密码占位符的packageSourceCredentials部分的nuget.config副本。然后，我将现有的nuget.config替换为此文件，并用环境变量替换用户名和密码。
唯一的缺点是我需要保持两个配置文件同步。如果我修改了项目中的nuget.config，我需要记得同时更新副本。
nuget.config.template
<?xml version="1.0" encoding="utf-8"?>

<packageSources>
<add key="GitHub private registry" value="https://nuget.pkg.github.com/your_orga/index.json" />

<add key="Username" value="USER" />
<add key="ClearTextPassword" value="PW" />

In your private feed if it's azure artifacts create a personal access token with full access.
Add a NuGet.Config file to the root of your project
<configuration>
<packageSources>
<add key="MyPrivateFeed" value="https://myfeed.url/index.json" />
</packageSources>
<packageSourceCredentials>
<MyPrivateFeed>
<add key="Username" value="myusername" />
<add key="ClearTextPassword" value="xq6n4lvnayeo2f467osasdasdgj4nat7xw2mkm7qwowvqeutjdueq" />
<add key="ValidAuthenticationTypes" value="basic" />
</MyPrivateFeed>
</packageSourceCredentials>
</configuration>
the ClearTextPassword key is your PAT
Add these two-line to the copy section of your docker file
COPY "NuGet.Config" "/"
RUN ["cp", "/NuGet.Config", "/root/.nuget/NuGet/NuGet.Config"]
and finally run your docker build it should be work.
COPY到正确的目录，不需要使用cp），否则会创建一个不必要的层。 - Alex Povel2023年的答案
这段代码针对WebApplication3运行得很好。我们使用BaGet NuGet服务器作为Nuget.org和我们的构建服务器之间的代理，以便更快地加载我们使用的常见包。

nuget source 命令是 nuget.exe 命令行界面的一部分，只能在 Linux 上与 Mono 结合使用。因为 mcr.microsoft.com/dotnet/core/sdk 镜像是一个 Linux 容器（确切地说是 Debian），所以您需要自己安装 Mono 和 Nuget 才能使用该命令。另一个选择是获取 官方 Mono Docker 镜像 并将 .NET Core 和 NuGet.exe 安装到其中。
