Docker build jfrog artifactory private feed authentication via environment variable not working

zenwalker1985 · January 28, 2024, 10:12am

After going through or referring through alot of documentation and SO threads or in this forum on using Nuget.config file to restore build process; i give up and here asking for help.

>docker info
Client:
 Version:    24.0.6
 Context:    default
 Debug Mode: false

My Docker file:

FROM mcr.microsoft.com/dotnet/framework/sdk:4.8 AS buildPhase
ARG BUILD_CONFIGURATION=Release
ARG ARTIFACTORY__API_KEY=%ARTIFACTORY__API_KEY%
ARG ARTIFACTORY__USER=%ARTIFACTORY__USER%
WORKDIR /src
COPY ["MyProj/MyProj.csproj", "MyProj/"]
COPY ./Nuget.config /src
RUN dotnet restore "./MyProj/MyProj.csproj" --configfile /src/Nuget.config

My Nuget.config file:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>    
    <add key="dev" value="https://xyz.jfrog.io/artifactory/api/nuget/v3/dev-nuget" />
  </packageSources>
  <packageSourceCredentials>
    <dev>
      <add key="Username" value="%ARTIFACTORY__USER%" />
      <add key="ClearTextPassword" value="%ARTIFACTORY__API_KEY%" />
    </dev>
  </packageSourceCredentials>
    <packageSourceMapping>
        <packageSource key="dev">
            <package pattern="*" />
        </packageSource>
    </packageSourceMapping>
</configuration>

With above configuration; i am trying to set the environment variables for Nuget feed by following this article: dotnet-docker/documentation/scenarios/nuget-credentials.md at main · dotnet/dotnet-docker · GitHub

No matter what i try (powershell/cmd) i am unable to get the restore phase success in dockerfile.

Below are the commands i am issuing:

> $env:ARTIFACTORY__USER = 'user@user.com'
>  $env:ARTIFACTORY__API_KEY = 'apikey'
> docker build --build-arg $env:ARTIFACTORY__API_KEY --build-arg $env:ARTIFACTORY__USER -f .\Custom.Dockerfile .

Errors i get are and docker build output:

As you can see; the host is reachable from the container; its just that it can not authenticate.

Kindly please help.

Thanks

Thank you for your reply.

Kindly please note that the docker image (base) i am referring to or using here is windowservercore having 4.8 framework installed.

Hence; i guess (plz correct me); i can not use ${ARTIFACTORY__USER} in the nuget.config and also
i wont be able to use sed command as powershell does not support sed command.

However; i guess using equivalent replacement of sed in powershell; i should get it done.

Ill try and revert back.

Thanks

Finally i was able to get this working.

Below is my dockerfile. The image is a windows container and this is working on Docker desktop Windows container mode

#FROM mcr.microsoft.com/dotnet/framework/sdk:4.8 AS build
#ARG BUILD_CONFIGURATION=Release
#ARG ARTIFACTORY__API_KEY
#ARG ARTIFACTORY__USER

#WORKDIR /src
#COPY . /src

#RUN (Get-Content /src/Nuget.config).replace('%ARTIFACTORY__USER%', $env:ARTIFACTORY__USER) | Set-Content /src/Nuget.config
#RUN (Get-Content /src/Nuget.config).replace('%ARTIFACTORY__API_KEY%', $env:ARTIFACTORY__API_KEY) | Set-Content /src/Nuget.config

#RUN dotnet publish "./MyProj/MyProj.csproj" --configfile /src/Nuget.config -c $env:BUILD_CONFIGURATION  /p:OutputPath=/app/publish/MyProj -v d
